REFRIGERANT FLOW DIAGRAM YCWL Low-pressure liquid refrigerant enters the cooler tubes and is evaporated and superheated by the heat energy absorbed from the chilled liquid passing through the cooler shell. Low-pressure vapour enters the compressors where pressure and superheat are increased. High pressure superheated refrigerant enters the condenser shell where heat is rejected to the condenser water passing through the tubes. The fully condensed and subcooled liquid leaves the condenser and enters the expansion valve, where pressure reduction and further cooling takes place. The lowpressure liquid refrigerant then returns to the cooler. YCRL Low-pressure liquid refrigerant enters the cooler tubes and is evaporated and superheated by the heat energy absorbed from the chilled liquid passing through the cooler shell.

APPLICATION DATA Location Requirements To achieve optimum performance and trouble-free service, it is essential that the proposed installation site meet with the location and space requirements for the model being installed. 500 mm clearance above unit 3500 mm Installation of Vibration Isolators An optional set of spring type vibration isolators can be supplied loose with each unit. Pipework Connection The following piping recommendations are intended to ensure satisfactory operation of the unit. Failure to follow these recommendations could cause damage to the unit, or loss of performance, and may invalidate the warranty. The maximum fl ow rate and pressure drop for the cooler and condenser must not be exceeded at any time. The water must enter the heat exchangers by the inlet connection. A fl ow switch must be installed in the customer pipework at the outlet of the exchangers as shown in the arrangement diagrams, and wired back to the control panel using screened cable. This is to prevent damage to the exchangers caused by inadequate liquid fl ow. 800 mm Control Panel 800 mm The liquid pumps installed in the pipework systems should discharge directly into the unit heat exchanger sections of the system. The pumps require an autostarter (by others) to be wired to the control panel. 800 mm The clearances recommended are nominal for the safe operation and maintenance of the unit and power and control panels. Local health and safety regulations, or practical considerations for service replacement of large components, may require larger clearances than those given in this manual. Units are designed for indoor installation and not intended for wet, corrosive or explosive atmospheres. Installation should allow for water drain, ventilation and suffi cient clearance for service, including tube cleaning/ removal. For installation in equipment rooms near noise-critical areas, common walls should be of adequate sound attenuating construction, all doors should be tightly gasketed, and the unit should have vibration isolators fi tted. The concrete base must capable of supporting 150% of the operating weight. In case of upper fl oors, the unit and piping should be isolated from walls and ceiling. The unit may be bolted to the foundation using XX mm Ø holes. When lower transmitted vibration levels are required optional anti-vibration isolators can be supplied loose for site installation. Pipework and fi ttings must be separately supported to prevent any loading on the heat exchangers. Flexible connections are recommended which will also minimize transmission of vibrations to the building. Flexible connections must be used if the unit is mounted on anti-vibration mounts as some movement of the unit can be expected in normal operation. Pipework and fi ttings immediately next to the heat exchangers should be readily de-mountable to enable cleaning prior to operation, and to facilitate visual inspection of the exchanger nozzles. Each heat exchanger must be protected by a strainer, preferably of 20 microns, fi tted as close as possible to the liquid inlet connection, and provided with a means of local isolation. The heat exchangers must not be exposed to fl ushing velocities or debris released during fl ushing. It is recommended that a suitably sized by-pass and valve arrangement be installed to allow fl ushing of the pipework system. The by-pass can be used during maintenance to isolate the heat exchanger without disrupting fl ow to other units. Thermometer and pressure gauge connections should be provided on the inlet and outlet connections of each heat exchanger. Drain and air vent connections should be provided at all low and high points in the pipework to permit drainage of the system, and to vent any air in the pipes. Page 9

Liquid systems at risk of freezing, due to low ambient temperatures, should be protected using insulation and heater tape and/or a suitable glycol solution. The liquid pumps must also be used to ensure liquid is circulated when the ambient temperature approaches freezing point. Insulation should also be installed around the heat exchanger nozzles. Condenser Cooling Liquid System Water Treatment The unit performance given in the Design Guide is based on a fouling factor of 0.044 m² C/kW. Dirt, scale, grease and certain types of water treatment will adversely affect the heat exchanger surfaces and therefore unit performance. Foreign matter in the water system(s) can increase the heat exchanger pressure drop, reducing the fl ow rate and causing potential damage to the heat exchanger tubes. Aerated, brackish or salt water is not recommended for use in the water systems. JCI recommends that a water treatment specialist be consulted to determine that the proposed water composition will not affect the evaporator materials of carbon steel and copper. The ph value of the water fl owing through the heat exchangers must be kept between 7 and 8.5. For unit operation with chilled liquid temperatures leaving the cooler at below 4.5 C, glycol solutions should be used to help prevent freezing. This manual gives recommended solution strength with water, as a percentage by weight, for the most common types of glycol. It is important to check glycol concentration regularly to ensure adequate concentration and avoid possible freeze-up in the cooler. Pipework Arrangement The following are suggested pipework arrangements for single unit installations. For multiple unit installations, each unit should be piped as shown. Recommendations of the Building Services Research Association -Isolating Valve - Normally Open -Isolating Valve - Normally Closed -Flow Regulating Valve -Flow Measurement Device -Strainer -Pressure Tapping -Flow Switch -Victualic/Flanged Connection -Pipework Connection Types & Sizes For connection sizes relevant to individual models refer to the physical data tables in this manual Chilled Liquid System Page 10

Refrigerant Relief Valve Piping The compressor, cooler and condensers are each protected against internal refrigerant over-pressure and fi re by refrigerant relief valves. The pressure relief valve is set at the design pressure of the system and has discharge capacity required by the relevant standard. It is recommended that each valve should be piped to the exterior of the building so that when the valve is activated the release of high pressure gas and liquid cannot be a danger or cause injury. The size of any pipework attached to a relief valve must be of suffi cient diameter so as not to cause resistance to the operation of the valve. For critical or complex installations refer to EN13136. Unless otherwise specifi ed by local regulations, the internal diameter depends on the length of pipe required and can be estimated with the following formula: D 5 =1.447 x L Where: D = minimum pipe internal diameter (cm) L = length of pipe (m). If relief pipework is common to more than one valve its cross sectional area must be at least the total required by each valve. Valve types should not be mixed on a common pipe. Precautions should be taken to ensure that the exit of relief valves/vent pipe remain clear of obstructions at all times. Condenser Cooling Liquid Systems For primary cooling of units, condensers are usually piped in conjunction with a cooling tower or a dry cooler, although in some cases they can be cooled by well water. With liquid cooled units it is necessary to control coolant fl ow and / or temperature into the condenser to maintain refrigerant pressure as constant as possible to ensure satisfactory operation of the expansion valves. The aim is to maintain a stable discharge pressure as low as possible, but at least 4.8 bar above suction pressure. This can be done at a fi xed value above the highest expected suction pressure, or by also measuring suction pressure and using differential control. In either case condenser cooling liquid fl ow and temperature limits must also be observed. Inlet Temperature Control (by others) For a cooling tower / dry cooler system, the simplest forms of control are to use fan cycling, fan speed control, or air damper control, with the tower having a thermostat in its sump. This will ensure stable condenser cooling liquid temperature sensing at design conditions and should be adjusted to ensure a condenser cooling liquid entering temperature of not lower than 18 C at lower ambient conditions. If these methods are not available, or a cooling tower is not the source of cooling water, then a three way valve recirculation system can be used with control based on condenser inlet liquid temperature. In this case the objective is to maintain the inlet cooling liquid temperature as low as possible, although still observing the minimum limit of 18 C. Direct Pressure Control (by others) With YCWL units it is possible, if desired, to control the condenser cooling liquid inlet temperature / fl ow directly from the unit refrigerant pressure. The refrigerant pressure can either be used to control cooling tower / dry cooler effectiveness by controlling fans or dampers on the tower, or to control condenser fl ow using a three way bypass valve. Page 11

CONDENSERLESS UNIT REFRIGERANT PIPING General When the unit has been located in its fi nal position, the unit piping may be connected. Normal installation precautions should be observed in order to receive maximum operating effi ciencies. All piping design and installation is the responsibility of the user. JOHNSON CONTROLS ASSUMES NO WARRANTY RESPONSIBILITY FOR SYSTEM OPERATION OR FAILURES DUE TO IMPROPER PIPING OR PIPING DESIGN. All fi lter driers, sight glasses, expansion valves and liquid line solenoid valves are factory installed on each refrigerant circuit. Interconnecting refrigerant piping and refrigerant charge are supplied and installed by others. Refrigerant Line Sizing Refrigerant piping systems must be designed to provide practical line sizes without excessive pressure drops, prevent compressor oil from being trapped in the refrigerant piping, and ensure proper fl ow of liquid refrigerant to the thermal expansion valve. Considerations should be given to: 1) Discharge line pressure drop due to refrigerant fl ow. 2) Discharge line refrigerant velocity for oil return. 3) Liquid line pressure drop due to refrigerant fl ow. 4) Liquid line pressure drop (or gain) due to vertical rise of the liquid line. To ensure a solid column of liquid refrigerant to the expansion valve, the total liquid line pressure drop should never exceed 275 kpa. Refrigerant vapour 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 5.1 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 the vertical rise. The value of static head loss of 11.3 kpa/m 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 2 cm/m in the direction of the refrigerant fl ow to aid in the return of oil to the chiller. All discharge lines with a vertical rise exceeding 90 cm should have a P trap at the bottom and top of the riser. Discharge lines with a vertical rise exceeding 7.5 m should be trapped every 4.5 m. Refrigerant Charge The chiller is charged and shipped with a dry nitrogen holding charge. 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. Final adjustment of refrigerant charge should be verifi ed by subcooling values (refer to IOM section on Pre-Startup for checking subcooling). ELECTRICAL CONNECTION The following connection recommendations are intended to ensure safe and satisfactory operation of the unit. Failure to follow these recommendations could cause harm to persons, or damage to the unit, and may invalidate the warranty. No additional controls (relays, etc.) should be mounted in the control panel. Power and control wiring not connected to the control panel should not be run through the control panel. If these precautions are not followed it could lead to a risk of electrocution. In addition, electrical noise could cause malfunctions or damage the unit and its controls. Power Wiring These units are suitable for 380 or 400 V, 3 phase, 50 Hz nominal supplies only. All electrical wiring should be carried out in accordance with local regulations. Route properly sized cables to the cable entries in the top of the power panel. In accordance with EN 60204 it is the responsibility of the user to install over current protection devices between the supply conductors and the power supply terminals on the unit. To ensure that no eddy currents are set up in the power panel, the cables forming each 3 phase power supply must enter via the same cable entry. All sources of supply to the unit must be taken via a common point of isolation (not supplied by JCI). Single Point Power Supply Wiring All models require one fi eld provided 400 V, 3Ø, 50 Hz + PE (Protected Earth) supply to the unit with circuit protection. Connect the 3 phase supply to the non-fused disconnect switch located in the power panel using M10 lugs Connect the earth wire to the main protective earth terminal located in the power panel. Page 12

Remote Emergency Stop Device If required, a remote emergency stop device may be wired into the unit. This device should be rated at 16 amps, 110 V, AC-15. The device should be wired into terminals L and 5 in the power panel after removing the factory fi tted link. Control Wiring - Voltage Free Contacts All wiring to the voltage free contact terminal block requires a supply provided by the customer maximum voltage 254 Vac, 28 Vdc. The customer must take particular care deriving the supplies for the voltage free terminals with regard to a common point of isolation. Thus, these circuits when used must be fed via the common point of isolation so the voltage to these circuits is removed when the common point of isolation to the unit is opened. This common point of isolation is not supplied by JCI. In accordance with EN 60204 it is recommended that the customer wiring to these terminals uses orange wires. This will ensure that circuits not switched off by the units supply disconnecting device are distinguished by colour, so that they can easily be identifi ed as live even when the unit disconnecting devices are off. The YORK voltage free contacts are rated at 125 VA. All inductive devices (relays) switched by the YORK voltage free contacts must have their coil suppressed using standard RC suppressors. If these precautions are not followed, electrical noise could cause malfunctions or damage to the unit and its controls. Chilled Liquid Pump Starter Terminals 23 and 24 close to start the liquid pump. This contact is closed if there is a Leaving Liquid Temperature Cutout or any of the compressors are running or the daily schedule is not calling for a shutdown with the unit switch on. The contact must be used to ensure that the pump is running in the event of a Leaving Liquid Temperature Cutout. The pump contact will not close to run the pump if the unit has been powered up for less than 30 seconds, or if the pump has run in the last 30 seconds, to prevent pump motor overheating. Run Contacts Terminals 25 and 26 close to indicate that refrigerant system 1 is running and terminals 27 and 28 close to indicate that refrigerant system 2 is running. Alarm Contacts Control Wiring - System Inputs All wiring to the control terminal block (nominal 30 Vdc) must be run in screened cable, with the screen earthed at the panel end only. Run screened cable separately from mains cable to avoid electrical noise pick-up. The voltage free contacts must be suitable for 30 Vdc (gold contacts recommended). If the voltage free contacts form part of a relay or contactor, the coil of the device must be suppressed using a standard RC suppressor. The above precautions must be taken to avoid electrical noise which could cause a malfunction or damage to the unit and its controls. Flow Switch A chilled liquid fl ow switch of suitable type must be connected to terminals 13 and 14 to provide adequate protection against loss of liquid fl ow. Remote Start/Stop Connect a remote switch to terminals 13 and 51 to provide remote start/stop control if required. Remote Reset of Chilled Liquid Setpoint The PWM input (terminals 13 and 20) allows reset of the chilled liquid setpoint by supplying a timed contact closure. Refer to Section 6 for details. Remote Load Limiting Load limiting prevents the unit from loading beyond a desired value. The unit % load limit depends on the number of compressors on the unit. The load limit inputs to terminals 13 and 21 work in conjunction with the PWM input to terminals 13 and 20. Heat Pump Kit When the Non-reversible Heat Pump Option is fi tted the heat pump mode is selected by closing a voltage free contact between terminals 13 and 50. EMS Analogue Input Provides a means of resetting the leaving chilled liquid temperature from the BAS/EMS. Accepts 4 to 20 ma, 0 to 20 ma, 0 to 10 Vdc or 2-10 Vdc. Connect to terminal A+ and A-. Disabled when using Modbus or BACnet MS/TP communications. Modbus and BACnet MS/TP Enable communications with building protocol systems using Modbus or BACnet protocol. Connect through standard RS485 port. Disabled when using EMS Analogue Input. Each refrigerant system has a voltage-free normally open contact that will close when control power is applied to the panel, if no fault conditions are present. When a fault occurs which locks a system out, or there is a power failure the contact opens. To obtain a system alarm signal, connect the alarm circuit to terminals 29 and 30 for No. 1 system and terminals 31 and 32 for No. 2 system. Page 13
