9 SECTION 1 - GENERAL INFORMATION 1 Mechanical Specifications Overview YORK Air-Cooled Condensers, Models VDC-113D10 through VDC-266C60, are available in 66 standard model sizes for air conditioning and refrigeration applications, and may be used with any type of compressor for halocarbon refrigerants. YORK Air-Cooled Fluid Coolers, Models VD- CF113B10 through VDCF268B60, are available in 22 standard model sizes for commercial and industrial fluid cooling and may be used with water or glycol. Contact Johnson Controls for special applications, for example, winter-weather chiller economizer duty or cooling industrial fluids. Air-cooled condensers and fluid coolers air-sides operate dry (requiring a minimum of maintenance) and do not require pump and water piping installation except for fluid-side fluid cooling. Vertical airflow units are standard design for low silhouette applications. Legs Made from heavy-gauge galvanized steel with foot pads and mounting holes on the bottom of each leg. Coil Seamless copper tubes are expanded into full-collar aluminum fins. Fins have a corrugated surface to enhance heat transfer. Fin edges are rippled to work harden and stiffen material for resistance to mechanical damage. Return bends and headers are brazed with highly ductile silver-bearing copper alloy. Coil casings and tubesheets are manufactured from galvanized steel. The tubesheets include aluminum inserts to prevent wear at the juncture of the tubes and tubesheets. Prior to shipment, coils are strength and leak tested at design pressure, dehydrated, evacuated, pressurized with dry air or nitrogen, and sealed for shipment. Condenser coils up to four fan lengths use 3/8 in. OD internally enhanced microfin tubes for optimum performance. Five- and six-fan length coils use 1/2 in. OD tubes. Fluid coolers use 5/8 in. OD tubes for low pressure drop. For R-22, R-134a, R-407C, R-404A, and R-507A condensing, the 3/8 in. and 1/2 in. OD tube coils have a 420 psig (29 barg) design pressure at 250 F (121 C) for up to a 140 F (60 C) condensing temperature. For R-410A, the 3/8 in. OD tube coils have a 650 psig (44.8 barg) design pressure at 250 F (121 C) for up to a 140 F (60 C) condensing temperature. For fluid coolers the 5/8 in. OD tube coils have a 250 psig (17.25 barg) design pressure for up to 145 F (62.8 C) entering fluid temperature. Headers Heavy-wall copper tube headers are designed for low pressure loss and proper refrigerant distribution. Double-wide units feature completely separate headers for each system circuit so there is no danger of refrigerant leakage between circuits. Inlet and outlet connections are provided. Integral subcooling is available for condensers. Housing The unit structure is comprised of heavy-gauge galvanized steel panels coated with baked-on champagnecolored powder paint, which, when subjected to ASTM B hour salt spray testing, yields a minimum ASTM 1654 rating of "6". These panels are assembled with high-tensile strength fasteners. Fan panels have long, smooth-radius outlet orifices to ensure high energy efficiency and low noise level. Each fan section is fully compartmentalized to prevent fan windmilling. Fan Guards Heavy-gauge OSHA-accepted fan guard design uses corrosion resistant, coated-steel wire. Fans High-efficiency, high-strength airfoil-profile blade fans are used for low noise and energy-efficient performance. Motors Totally enclosed air-over (TEAO) motors have builtin thermal overload (ATO) protection and are inverter duty ready. They feature ball bearings that are doublesealed and permanently lubricated. Standard motor is 2.0 hp, 3-phase, 60 Hz, 200, 230, 460, or 575 volts. Optional 1.0 hp, 3-phase, 60 Hz, 200, 230, 460, or 575 volts and 2.0 or 1.0 hp, 3-phase, 50 Hz, 380, 400, or 415 volts are also available. JOHNSON CONTROLS 9

10 SECTION 1 - GENERAL INFORMATION Motor Mounts Heavy-gauge galvanized steel channels are used to mount motors.

11 SECTION 2 - PRODUCT DESCRIPTION Accessories and Options Special Coils While standard aluminum fins are compatible with most environments, when a unit is subjected to an especially corrosive atmosphere, such as coastal air with a high concentration of salt, special fin treatment may be required. The following options are available for these applications. Holly Gold Coat This gold-colored, corrosion-resistant, polyester-polymer-coated aluminum fin passes 1000 hours of ASTM B117 salt spray testing. Available only with 3/8 in. OD tube coils. ElectroFin Coat ElectroFin Coat is applied to the completed coil, protecting the tubes, fins, headers, and galvanized steel casing with a coating that passes 5000 hours of ASTM B117 salt spray testing. Does not include shipped loose manifold kit. Copper-Finned Coils Copper-finned coils are available for applications where the environment may cause galvanic corrosion of aluminum fins. Available only with 3/8 in. OD tube coils. Sealtite Conduit All fan motor wiring enclosed in sealed conduit. Manifold Kit Ties dual inlet and outlet connections together on double-wide units for a single field connection (shipped loose for field installation). Typically used on doublewide condensers for use with a single chiller circuits or double-wide fluid coolers. Not available from factory on units with 4 1/8 in. OD connections. Motor Wiring Options for Fan Control Motors are wired to contactors located in a UL-listed NEMA 4, weather-resistant enclosure, which includes a non-fused disconnect switch, motor fuses, contactors, and an integral 115 volt control transformer. See Table 10 on page 59 and Table 11 on page 59, for fan-cycling control settings or contact Application Engineering for support. Enclosure ships mounted. If there is a concern about noise due to fan cycling, it is recommended that Head Pressure Control (Variable Speed Drive (VSD) Ready) be used. Double-Wide Unit Fan Cycling Fan Cycling Options for Double-Wide Units are available with fans cycling in pairs or, for temperature-controlled and pressurecontrolled fan cycling, with individual fan-bank fan cycling so the VDC can serve individual chiller circuits. Fan Cycling Options Head Pressure Control by Temperature Motors are wired for temperature-controlled fan cycling. A temperature sensor, supplied with a clip for mounting in condenser s air stream or a bulb well for installation in fluid cooler s leaving fluid piping, must be field installed. Fans next to the header are always running when unit is activated by run signal. Receivers are not required. For fluid coolers, the lowest allowable leaving fluid temperature is -13 F (-25.0 C) which can be safely done with 50% Ethylene Glycol or 50% Propylene Glycol and a minimum ambient of -20 F (-28.9 C). When a glycol heat transfer fluid is used in the YORK VDCF fluid cooler ensure that the fluid maintains the correct design glycol concentration. It is imperative to maintain a high enough concentration to prevent the fluid cooler from experiencing a solution freeze that can permanently damage the coil. Johnson Controls recommends that the fluid be checked to verify that the correct concentration is maintained at the beginning of seasonal cold weather or any time the system is opened or a leak is discovered. It is also important that the unit is rated for the concentration of glycol that will be used. Higher concentrations than required will reduce the unit's heat transfer capacity and increase fluid pump horsepower. The concentration required for the given application will depend on the particular glycol-based heat transfer fluid used and the lowest expected temperature. Different fluids have different specific gravity, specific heat, viscosity and thermal conductivity at different percentages and temperatures. Typically the system should be protected to 15 degrees below the lowest anticipated temperature. The fluid manufacturer's recommenda- 2 JOHNSON CONTROLS 11

12 SECTION 2 - PRODUCT DESCRIPTION FORM NM1 tions should be closely followed for your particular application. The A350 controller and stage module are supplied with this option to control the fans. Head Pressure Control by Pressure Required when selecting a VDC for use as a remote condenser for a YCRL chiller. Motors are wired for pressure-controlled fan cycling. Included pressure transducer(s) must be field installed. Fans next to the header are always running when unit is activated by run signal. Receivers are not required. The P470 controller and stage module are supplied with this option to control the fans. Head Pressure Control (VSD Ready) Motors are wired for variable speed fan control. VSD bypass control circuit is included, but inverter drive (VSD) is not included. Temperature or pressure sensor(s) for control must be field provided and installed, if desired. Field-installed inverter drives (VSDs) shall be mounted on or in close proximity to the VDC unit. The inverter drive shall be equipped with load reactors for installations that require more than 25 feet of wire between the inverter and the VDC unit or whenever distortion is a concern to prevent voltage spikes that can damage the fan motors and void the VDC motor warranty. Motor damage caused by an improperly installed VSD is not warranted. The VSD s switching frequency shall not exceed 4 KHz. When this option is selected, the option Sealtite Conduit on page 11 shall also be selected to ensure that the motor wire is shielded from voltage spikes. Grounding of conduit and all wiring is of extreme importance. See Figure 18 on page 56 and VSD Inverter Wiring on page JOHNSON CONTROLS

13 SECTION 3 - HANDLING AND STORAGE Preface Your Johnson Controls Air-Cooled Condenser or Fluid Cooler incorporates the finest in engineering design, materials, and corrosion protection to provide a rugged long lasting unit. Proper installation, care and maintenance of your unit are essential to good performance and long life. Before rigging or beginning work on the unit, Johnson Controls recommends that experienced refrigeration contractors, operators, and maintenance technicians are formally trained on the Johnson Controls Air-Cooled Condenser features. Reading this manual is a minimum requirement. Before installing your unit, we suggest that you read the following instructions carefully and keep them handy for ready reference. After installation, the unit must be properly connected to appropriately designed and installed refrigeration systems. The engineering plans, piping layouts, etc., for the Johnson Controls Air-Cooled Condenser or Fluid Cooler and associated system components must be detailed in accordance with local/governing codes and the best industry standards and practices such as those outlined in current industry literature. Reference the DX Piping Guide, Form ES2 and the 2010 ASHRAE Refrigeration Handbook, Chapter 1, especially noting the Safety Requirements section for high pressure refrigerants on page Shipping Inspection Carefully examine the unit and notify the transportation agent of any missing parts or damage. It is advisable to inspect the unit as soon as received and to make a record of the serial number, and motor data. The unit shipment should be checked on arrival to ensure that all major pieces, boxes and crates are received. The unit should be checked on the trailer or rail car before unloading, for any visible signs of damage. Any damage or signs of possible damage should be reported to the transportation company immediately for their inspection. Contact the Johnson Controls Regional or District office in order for a Johnson Controls Representative to assist in filing damage claims. Johnson Controls will not be responsible for any damage in shipment or at job site, or loss of parts, if these shipping inspection instructions are not followed. (Refer to BOS Document Submitting and Processing Claims for materials lost or damaged in transit BEHQ) Once received at the job site, all containers should be opened and contents checked against the packing list. Any material shortage should be reported to Johnson Controls immediately. (Refer to Shipping Damage Claims, Form NM.) Coil Inspection The refrigerant coil has a low pressure charge from the factory. Check the coil to see that the holding charge is intact. To do this, remove the 1/4 inch cap and briefly depress the Schrader valve located on the liquid or suction header of each circuit to verify pressure. The charge must be maintained until refrigerant or fluid piping is connected to the unit. A coil that does not have a charge may have been damaged during transit. If the charge is not present when the unit is received, the coil must be pressure tested to 100 psig with dry nitrogen gas to confirm that it is leak free. Contact Johnson Controls before installing any air-cooled condenser or fluid cooler unit that has lost the factory charge. When communicating with the factory, refer to the model and serial numbers which are located on the unit nameplate. Safety Requirements Only experienced, qualified personnel should install, operate and maintain refrigeration equipment. Perform frequent visual inspections and continuously monitor a condenser to prevent the escape of refrigerant. Use electronic refrigerant detectors in the unit proximity for continuous monitoring and detection of the presence of refrigerant in the atmosphere. 3 JOHNSON CONTROLS 13

15 SECTION 4 - INSTALLATION Mounting Once the unit is placed in the desired location, secure legs to floor or steel work with 3/4" diameter bolts to prevent movement. The top should be level and the unit should be supported along its entire length (i.e., every leg should be secured). Use of vibration pads or isolators is recommended. The supporting structure must be strong enough to support the weight of the unit. Crane Rigging Instructions All units are designed for removal from the truck by crane only. Use lifting brackets shown on Figure 2 on page 15. Be careful to lift units evenly and balanced to avoid undue stress on the equipment. Refer to customer submittal drawings for dimensional data and weight before installing units. 4 Figure 2 - Rigging And Leg Mounting Drawing LD14082 JOHNSON CONTROLS 15

16 SECTION 4 - INSTALLATION Location Johnson Controls remote Air-Cooled Condensers and Fluid Coolers are designed to meet practically any requirement for mounting either indoors or outdoors. Care should be taken not to mount the unit where it is continually exposed to loose dirt or foreign matter which might clog the coil surface. The unit must be mounted in a level position, both front-to-back and side-to-side. An important consideration when locating the condenser is providing for adequate airflow to and from the unit. A minimum distance of four feet is recommended on all sides of the unit, with eight feet minimum recommended between adjacent air-cooled condensers. The capability and performance of the unit is dependent upon the unimpeded flow of ambient air over the extended surface for removal of heat from the refrigerant discharge gas within the coil. Solar effect has negligible bearing on the performance of the air-cooled condenser. Indoor Applications When the condenser or fluid cooler is mounted indoors, the air leaving the unit must be discharged to the outdoors to prevent recirculation of heated air through the unit. Provision must also be made for sufficient fresh air intake into the area where the unit is located. When a discharge duct is used with a propeller fan, the duct's added static pressure leaves the unit subject to diminished heat transfer capacity because of a reduction in airflow. The unit's rated capacity can be preserved by designing the duct for negligible pressure loss, by the addition of an external fan to overcome the duct's static pressure, or by a combination of the two. All fan guards should be removed and access provided in the duct to allow for servicing the fan and drive assemblies. A flexible duct connection will minimize noise transmission. If louvers are to be installed on the duct outlet, the free open area should equal the duct cross sectional area. For ducts of greater or lesser cross sectional area, special fans and motors can be furnished by Johnson Controls. Consult the factory for specific recommendations and pricing. FORM NM1 If inlet ducts are not provided, unrestricted flow of fresh air to the unit must be ensured. Care must be taken to ensure that the fresh air supplied is at the ambient air temperature. If air is taken from an area where the heat exceeds the ambient air temperature, the unit s capacity will be reduced. The arrangement must ensure that heated condenser discharge air is not re-circulated to the air intake of the unit. Outdoor Applications Your Johnson Controls Air-Cooled Condenser or Fluid Cooler has the fan motor(s) located inside the casing and requires no special provisions for weather protection. Multiple units should be installed so that the discharge of one unit is not directed into the intake of another unit. A vertical airflow unit may be located without regard to prevailing wind. These units minimize fan noise and allow greater flexibility of location in relation to surrounding structures. When installing condensers and fluid coolers, a location should be chosen so that at least three sides of the unit have unrestricted airflow. The fan should have free flow unrestricted by any overhanging structures. The unit may be placed close to a building on one side with a minimum clearance of eight feet. In the case of multiple unit installations, units may be placed end-toend without penalty and side-by-side with a minimum of four feet apart for single-wide and eight feet apart for double-wide units. Where located on a roof, it is best to mount the unit with the longer side parallel to the roof edge to minimize the potential for drawing heated air from the roof surfaces. The rugged mounting legs of the Johnson Controls Air- Cooled Condensers and Fluid Coolers are designed to provide sufficient height for any operating condition. Mounting pads should be located for ground level installation. When the unit will be located where an excessive buildup of superheated air is expected, the unit should be mounted in a structural open frame. 16 JOHNSON CONTROLS

17 SECTION 4 - INSTALLATION Wiring A disconnect, as required by local codes, should be provided for each motor circuit. The motors have internal thermal overload protection; therefore, multiple motors may be started from each circuit. See SECTION 5 - TECHNICAL DATA for wiring diagrams. With factory wired motors, verify that the supply voltage is the same as the motor nameplate voltage. For field wiring, check the wiring terminals inside the motor to ensure that they are wired for proper power supply voltage. The wiring diagram is attached to the motor housing. Also, confirm fan rotation direction as indicated by the fan blades. Corrosive Environment These units must not be installed in environments that may be corrosive to the materials of construction. This could result in reduced performance, condenser fin deterioration and coil leaks not covered by warranty. Electric Power Supply Check the electrical characteristics on the unit nameplate to make sure the power supply is the same. Only qualified electricians should install the power supply. All work should be done in conformance with prevailing codes and regulations. Do not remove safety equipment or warning labels from equipment. Removal could result in serious injury or death. Disconnect the power supply to the unit before performing any service or maintenance. The disconnect should be locked in the OFF position following proper lockout tagging procedures. Refrigerant Piping - Condenser Special care must be taken to ensure adequate sizing of refrigerant piping for Johnson Controls Air-Cooled Condensers. Applicable standards should be consulted in this regard. The copper tubing should be de-oxidized and dehydrated Type L refrigeration tubing with wrought copper fittings employed. Keep all piping clean, and clean all pipe connections with a wire brush or the equivalent. Braze with 5% silver braze material with the recommended flux. Use a wet rag around the next solder joint when brazing. Piping systems with halocarbon refrigerants must be properly evacuated to remove noncondensables and moisture prior to the introduction of refrigerant. A vacuum of 750 microns is the minimum requirement to remove moisture. The liquid drain line should not be exposed to high temperatures, and therefore should be insulated if it passes through an environment where temperatures exceed 120 F. All refrigerant piping must be well supported and protected from vibration. The condenser piping connections should not be left open to the atmosphere for any longer than required for solder connections to be made. Install a shut-off valve at the receiver inlet (if used). Install a purge valve or fitting at the highest point in the discharge gas piping. In order to prevent condensed liquid refrigerant from causing damage to the compressor(s), install a trap in the vertical discharge piping at the compressor(s). The height of the trap should be 6 inches for every 10 feet of vertical discharge piping. If the height of the vertical piping makes this impractical, the trap may be replaced by a check valve. When installing refrigeration piping, make certain that it is well supported. Make sure the vibrations from the compressor, condenser and piping are not transmitted to the building. The use of a discharge muffler may be necessary to prevent noises due to refrigerant pulsations; particularly with high speed compressors. Refrigerant Line Sizing Refrigerant piping systems must be designed to provide practical line sizes without excessive pressure drops to prevent compressor oil from being "trapped" in the refrigerant piping, and to ensure proper flow of liquid refrigerant to the thermal expansion valve. Be sure to review DX Piping Guide, Form ES2. Considerations should be given to: 1. Discharge line pressure drop due to refrigerant flow. 2. Discharge line refrigerant velocity for oil return. 3. Liquid line pressure drop due to refrigerant flow. 4. Liquid line pressure drop (or gain) due to vertical rise of the liquid line. 5. Pressure rating of brazed Type L Copper tubing with high pressure refrigerants. 4 JOHNSON CONTROLS 17

18 SECTION 4 - INSTALLATION To ensure a solid column of liquid refrigerant to the expansion valve, the total liquid line pressure drop should never exceed 40 PSI (276 kpa). Refrigerant vapor in the liquid line will measurably reduce valve capacity and poor system performance can be expected. To allow adequate oil return to the compressor, discharge risers should be sized for a minimum of 1000 FPM (5.08 m/s) while the system is operating at minimum capacity to ensure oil return up the suction riser. Chiller Below Condenser On a system where the chiller is located below the condenser, the discharge line must be sized for both pressure drop and oil return. In some cases a double discharge riser must be installed to ensure reliable oil return at reduced loads. Condenser Below Chiller When the condenser is located below the chiller, the liquid line must be designed for both friction loss and static head loss due to the vertical rise. The value of static head loss of 5 PSI/ft. (3.4 kpa/30 cm) must be added to the friction loss pressure drop in addition to all pressure drops due to driers, valves, etc. Oil Traps All horizontal discharge lines should be pitched at least 1/4" per foot (2 cm/m) in the direction of the refrigerant flow to aid in the return of oil to the chiller. All discharge lines with a vertical rise exceeding 3 feet (.91 meters) should have a "P" trap at the bottom and top of the riser. Discharge lines with a vertical rise exceeding 25 feet (7.6 meters) should be trapped every 15 feet (4.6 meters). Refrigerant Piping Reference R-410A Copper Line Sizing When selecting pipe diameter and material for remote condenser piping R-410A systems, it is recommended that ASTM B280 material is used. For more details, refer to the 2014 ASHRAE Refrigeration Handbook, Chapter 1, and note that brazing reduces the strength of the heated pipe material to that of annealed material. Suggested Field Piping Arrangements This section shows four field piping arrangements for remote air-cooled condensers in field erected systems using receivers. Receivers are shown in Figures 3 through 6 for convenience. Many applications do not require receivers when the volume of the refrigerant charge does not exceed 80% of the condenser coil internal volume and can be stored entirely in the condenser coil. Loop Trap Discharge Line Condenser Compressor Liquid Line Receiver FORM NM1 Figure 3 - Condenser, Compressor And Receiver On Same Level LD16218 Figure 3 on page 18 covers a common application where the air- cooled condenser is located on the same elevation as the compressor and receiver. The discharge line in this case is not too critical. The main problem usually associated with this arrangement is insufficient vertical height to allow free draining of the liquid refrigerant from the condenser coil to the receiver. To prevent gas binding in the receiver and liquid buildup in the condenser coil, locate the receiver as far below the condenser outlet as possible. Liquid lines must be free of any loops or traps and horizontal runs must be pitched toward the receiver. YCRL Line Sizing Notes If the VDC is used in conjunction with a YCRL chiller with a design pressure of 650 psig, a mechanical high pressure cutout to shut the unit off at 585 psig, and (the unit) is rated at 650 psig, the maximum discharge pipe diameter that can be used is 1-5/8". 18 JOHNSON CONTROLS

19 SECTION 4 - INSTALLATION Loop Loop Discharge Line A Condenser Condenser Condenser Discharge Line B Trap Liquid Line Discharge Line Trap Liquid Line Compressor Receiver Figure 4 - Capacity Controlled Systems LD16219 Figure 4 on page 19 shows the recommended configuration for applications of capacity controlled systems. Discharge line A is sized for the maximum load conditions. Discharge line B is sized for the minimum loading conditions at sufficient velocity to carry the oil to the condenser at the reduced capacity. Discharge Line Condenser Compressor Receiver LD16221 Figure 6 - Two Or More Condensers Connected To One Compressor Figure 6 on page 19 illustrates another common application where two or more separate air-cooled condensers are interconnected to a single compressor. In this case, each condenser must have both equal capacity and equal pressure drop. The piping must also be arranged to ensure equal lengths to and from each condenser. If unlike piping and/or unequal condensers are used, the unequal pressure drop will cause liquid to build up in one of the condensers, reducing its effective capacity. 4 Trap Compressor Receiver Liquid Line Figure 5 - Condenser Higher Than Compressor And Receiver LD16220 Recommended Refrigeration Line Sizes The recommended refrigerant line sizes (discharge line-compressor to condenser and liquid line-condenser to receiver) can be determined from the DX Piping Guide, Form ES2, while exercising care with regards to internal working pressure of copper piping with brazed joints for use with high-pressure refrigerants. Figure 5 on page 19 illustrates a typical piping arrangement where the remote air-cooled condenser is located on a higher elevation than the compressor or receiver. In this arrangement, the design of the discharge line is very critical and should be modified to the arrangement in diagram Figure 4, unless a very constant and steady load is maintained.

Figure 8 - Refrigerant Connections - VDC Receiver Location (if Required for Refrigerant Storage) It is preferable that the receiver be located in an ambient temperature above 65 F. When located in a lower ambient temperature, provision should be made to heat and insulate the receiver, especially if long off-cycles are encountered. Table 1 on page 21 shows suggested receiver and heater sizes. The receiver should be insulated with 1-inch thick Armaflex insulation or equivalent. Before applying the receiver insulation, the heater cable should be wrapped around the receiver throughout the length for even heat distribution. The heater must be field connected to the proper voltage and controlled so that it is energized on system shutdown.

22 SECTION 4 - INSTALLATION Refrigerant Charge The chiller is charged and shipped with a dry nitrogen holding charge. The chiller and the remote piping condenser must be evacuated and the operating charge for the chiller, remote condenser and refrigerant piping must be weighed in after all refrigerant piping is installed, leak checked, and evacuated. A minimum of 70% of the calculated complete system charge must be installed before attempting to operate a system. Final adjustment of refrigerant charge should be verified by subcooling values. FORM NM1 Use of refrigerant other than that stamped on the nameplates may cause damage to the refrigeration coils. Coil must not be subject to higher pressure than design pressure stamped on the nameplate. The total system refrigerant charge is the sum of the operating charges of the evaporator, condenser and refrigerant piping. The Refrigerant charge for discharge lines and liquid lines may be found in Tables 15 and 16 respectively on pages 28 and 29 of the DX Piping Guide, Form ES2. The pump down capacity of the condenser should be equal to or greater than the total refrigerant charge required. Pumpdown capacity is normally the sum of the evaporator, condenser and refrigerant piping charges multiplied by LD16223 Notes: 1. Standard YORK fluid cooler with one single-circuit coil. 2. Standard YORK fluid cooler with two single-circuit coils, shown with optional manifolds (shipped loose), not available from factory on units with 4 1/8 in. OD connections.

59 SECTION 7 - UNIT OPERATION Standard Fan Cycling Air-cooled condensers must operate at lower than design ambient dry bulb temperature. A minimum operating pressure must be maintained under all ambient operating conditions to ensure sufficient pressure and satisfactory system operation. Therefore, if air-cooled condenser operation below 40 F ambient temperature is required, refer to Fan Cycling Options on page 11 and Low Ambient Control Options on page 60. The capacity of an air-cooled condenser is directly proportional to the TD, which is the temperature difference between the condensing temperature and the air dry bulb entering the condenser. A condenser is normally selected to operate on a TD suitable for summer ambient temperature conditions. The capacity of this condenser, however, is substantially increased when operated with low ambient temperatures. The result of the increase in condenser capacity is to reduce the system head pressure. When the ambient temperature drops below a certain value, the head pressure falls below the point where the expansion valve cannot properly feed the evaporator and very poor or unsatisfactory system operation results. On multiple fan units, individual fan sections can be cycled to not exceed nominal condenser capacity at low ambient conditions. Table 10 on page 59 provides minimum ambient temperatures for this method of control. Table 11 on page 59 gives individual thermostat settings for all units referenced to various design temperature differences. In lieu of thermostats, fan cycling can be controlled by pressure switches connected to condenser inlet (hot gas) headers. This is recommended for process applications. Contact Johnson Controls for special pricing.

60 SECTION 7 - UNIT OPERATION VDC Pressure Setting Guidelines When a YORK VDC is used as a remote condenser with a YCRL chiller, the VDC must be ordered and installed with the Head Pressure Control by Pressure option, which provides Johnson Controls model P470 pressure controllers factory mounted in the VDC control panel. P470 controller operating manuals, included in the VDC control panel, provide guidance for field fan-staging setup. Johnson Controls recommends the following pressure set points for general use; if excessive fan cycling is noted the final stage of cycling should be adjusted (deadband increased). The deadband proposed in these guidelines is set to 125 psi, which is the standard setting for Johnson Controls air-cooled R-410A units (YLAA, YCAL and YCRL). Two-stage units (2-fan single-wide, 4-fan double-wide VDC) Stage 1, ON when any compressor is ON. Stage 2, ON at 380 psig, OFF at 255 psig. Three-stage units (3-fan single-wide, 6-fan double-wide VDC) Stage 1, ON when any compressor is ON. Stage 2, ON at 380 psig, OFF at 255 psig. Stage 3, ON at 405 psig, OFF at 280 psig. Four-stage units (4-fan single-wide, 8-fan double-wide VDC) Stage 1, ON when any compressor is ON. Stage 2, ON at 380 psig, OFF at 255 psig. Stage 3, ON at 405 psig, OFF at 280 psig. Stage 4, ON at 430 psig, OFF at 305 psig. Compressor will unload when the discharge pressure reaches 565 psig. Low Ambient Operation Since air-cooled condensers are often required to operate over a wide range of ambient air temperatures and variable loading conditions, provision must be made to maintain the overall system balance. Any air-cooled condenser tends to run at a low head pressure when operating in a low ambient air temperature. Low head pressures can result in poor expansion valve operation, which will in turn cause poor system operation. Within limits, air conditioning applications allow the operating head pressure to vary with the ambient air temperature without adversely affecting the system operation. The head pressure lower limit depends upon the required pressure drop across the thermostatic expansion valve. For normal air conditioning applications, the low pressure limit should correspond to a condensing temperature of 65 to 70 F. This corresponds to an ambient air temperature lower limit of approximately 55 to 60 F. Air conditioning may not be required at or below these ambient temperatures. However, to ensure sufficient receiver pressure during compressor start-up, it is recommended that a high-pressure cut-in switch be used to allow the head pressure to rise before the condenser fan starts. Many applications, such as commercial refrigeration, require operation below the above ranges (55 to 60 F). Johnson Controls offers fan cycling to maintain a desired condensing pressure. Low Ambient Control Options FORM NM1 Fan Cycling Control On multiple fan units, individual fan sections can be controlled to prevent exceeding nominal condenser capacity at low ambient conditions. Table 10 on page 59 provides minimum ambient temperatures for effective fan cycle control. Lower ambient temperatures than listed are not recommended for this method of control. Table 11 on page 59 gives temperature settings for all units referenced to various design temperature differences. Head Pressure Control by Temperature on page 11 for VDCs and VDCFs and Head Pressure Control by Pressure on page 12 for VDCs can be used to control individual fans in single-wide models and individual fans or pairs of fans in double-wide models. Head Pressure Control (VSD Ready) on page 12 for VDCs and VDCFs can be used to vary speeds of all fans in unison. 60 JOHNSON CONTROLS

65 SECTION 8 - MAINTENANCE General When our Johnson Controls remote Air-Cooled Condenser or Fluid Cooler has been properly installed, it will require little in the way of regular service or maintenance. A regular schedule of periodic maintenance should be established, which includes a complete annual checkup. Motors are equipped with sealed bearings; no motor grease is required. Cleaning When visual inspection so indicates, the condenser coil should be cleaned with a vacuum cleaner, compressed air or brush to clear dust and debris which will impede performance. A clean coil saves energy. Consult the material Safety Data Sheet to determine a cleaning solution that is compatible with all parts of the unit. If the unit's casing shows signs of rust, the rust spots should be cleaned and sprayed with a rust preventative. Recommended Spare Parts See Renewal Parts Guide, Form RP1 for replacement and recommended spare parts for earlier as well as current models. 8 JOHNSON CONTROLS 65
