2 SAFETY CONSIDERATIONS Installation and servicing of air conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair or service air conditioning equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils and cleaning and replacing filters. All operations should be performed by trained service personnel. Observe precautions in the literature, tags and labels attached to the unit. Follow all safety codes Wear safety glasses and gloves. Use quenching cloth and have fire extinguisher available for all brazing operations. Use care in handling, rigging and setting bulky equipment. WARNING Be sure all power is shut off before performing maintenance or service. More than one disconnect may be present. PREINSTALLATION Moving and Storage To transfer unit from truck to storage site, use a fork truck. Do not stack units more than 2 high during storage. If unit is to be stored for more than 2 weeks before installation, choose level, dry storage site free from vibration. Do not remove plastic wrap or skid from unit until final installation. Remove plastic wrap. Examine unit for shipping damage. If shipping damage is evident, file claim with transportation agency. Remove base skid prior to actual installation. Check nameplate information against available power supply and model number description. UNIT POSITIONING The unit can be mounted on the floor for vertical application with return air entering the face of the unit and supply air discharging vertically through the top of the unit. The unit can be also applied in a horizontal arrangement with return air entering horizontally and the supply air discharging horizontally. When applying the unit in a horizontal arrangement, ensure the condensate drain pan is located at the bottom center of the unit for adequate condensate disposal. See Fig. 1 for condensate connections for each position. Typical positioning and alternate return air locations are shown in Fig. 1. Alternate return air locations can be used by moving the unit panel from the alternate return air location to the standard return air location. Fig. 1 Typical Unit Positioning Rigging All 40RM/RMS Series units can be rigged by using the shipping skids. Units are shipped fully assembled. Do not remove shipping skids or protective covering until unit is ready for final placement; damage to bottom panels can result. Use slings and spreader bars as applicable to lift unit. INSTALLATION General Allow 21/2 ft at front and side of unit for service clearance and airflow. For units equipped with an economizer, refer to accessory installation instructions for additional clearance requirements. Be sure floor, wall or ceiling support unit weight. See Table 1A, 1B, 1C, 1D for details. IMPORTANT Do not attempt to install the unit with return air entering top panel of the unit. Condensate will not drain from unit. Uncrating Move unit as near as possible to final location before removing shipping skid.

3 Unit Isolation Where extremely quiet operation is essential, install isolators between floor and base of unit or between ceiling and top section of unit. Be sure that unit is level and adequately supported. Use channels at front and sides of unit for reference points when leveling. Refrigerant and Chilled Water Piping Access The 40RM/RMS series units come with stubout pipes for easy refrigerant and chilledwater piping. These pipes are protruded outside the units for ready installation. The standard location of these pipes are at the right side. However, should alternate route of pipings be required there are also available knockout holes at the opposite side of the unit. Refrigerant Piping See Tables 1A, 1B, 1D, 1E for refrigerant pipe connection sizes. For ease in brazing, it is recommended that all internal and external solder joints be made before unit is placed in final position. The 40 RM directexpansion coils have internal factoryinstalled thermostatic expansion valves (TXV s), distributors and nozzles for use with R22. Knockouts are provided in the unit corner posts. The sensor bulb capillary tubes must be routed from the TXVs inside the unit through one of the piping access holes. Clamp the TXV sensor bulb on a vertical position of the suction line, outside the unit. See Fig. 3.1 and RM series evaporator have a facesplit design. Ensure that lower circuit of the coil is first on/last off when connected to the condensing unit and /or system controls. External TXV equalizer connections are provided and factory brazed into the coil suction manifolds. If suction line must be horizontal, clamp bulb onto suction line at least 45 degrees above the bottom at approximately the 4 o clock or 8 o clock position. See Fig. 2. FOR 40 RM 016 & 024 FOR 40 RM 024 ONLY Fig. 3.1 FaceSplit Coil Suction and Liquid Line Piping (Typical for 40RM 016/024) Fig. 3.2 FaceSplit Coil Suction and Liquid Line Piping (Typical for 40RM 028/034) Fig. 2 TXV Sensing Bulb Location Note: The 8 o clock position is shown above IMPORTANT NEVER attach the sensor to the suction manifold. DO NOT mount the sensor on a trapped portion of the suction line.

4 pressure created by fans, preventing complete drainage. Conditions will worsen as filters become dirty. Install cleanout plugs in traps. Pitch drain line downward to an open floor drain or sump. Provide service clearance around drain line to permit removal of panels. Observe all local sanitary codes. As shipped, the unit s condensate drain pan is not sloped towards the drain connection. The pan slope must be changed to pitch towards the side of the unit with the drain connection. See Fig. 6. Loosen the 2 screws next to the drain outlet at both ends of the unit, push drain pan down in the slots near the drain connections, and up in the slots on the opposite end. Retighten screws. The pan should have a pitch of at least ¼ in. over its length toward the drain connection. Fig. 4 Typical Evaporator Coil Connections (40RM) Chilled Water Piping See Table 1B for chilled water connection sizes. For ease in piping connection it is recommended that all external fittings be made before the unit is placed in a final position. Alternative holes are available on the opposite Post Corner should the alternate route of pipings are required. To design and install chilled water piping, consult Carrier System Design Manual. See Fig. 7 for an example of a typical installation. Recommended fittings are listed in Table 1B. To access 40RMS coil vents and drains, remove the unit side panel over the coil header. Vent and drain plugs are on the top and bottom of the header, respectively. Fig. 5 Condensate Drains Condensate Drain Install a trapped condensate drain line to unit connection as shown in Fig. 5. Some areas may require an adapter to connect to either galvanized steel or copper pipe. Note: A trap must be installed in the condensate drain line to ensure that the static pressure of fans is balanced with the water column in the drain line and that the condensate can drain completely from pan. Without a trap, air can be drawn up drain line until water level in condensate pan becomes equal to static Fig. 6 Drain Slope Adjustments

6 Connecting Ductwork Refer to Carrier System Design Manual for the recommended design and layout of ductwork. Fig. 10 shows recommended duct connection to units with two fans. Most unit service can be performed by removing one or both of the unit s side panels. Coil cleaning or removal or insulation cleaning may require removal of rear, top or bottom panel, depending on the unit s orientation. When service is completed, replace unit panels. Panels Panels are fastened to unit frame with sheet metal screws. Fan coil and coil compartment must be sealed tightly after service to prevent air from bypassing the cooling coil. Fan Motor Lubrication Fan motor supplied with unit is permanently lubricated and requires no further lubrication. Fan Shaft Bearings Bearings on size units have pillowblock bearings (Fig. Fig. 10 Typical Fan Discharge Connections for Multiple Fan Units START UP Before starting the unit, check the following and correct as necessary: Is the unit solidly supported? Is fan adjusted for speed and pulley alignment? Are pulleys, motors and bearings securely mounted? Is condensate drain pan pitched for correct drainage? Are coil baffles tight against coil to prevent air bypass? Are all panels securely fastened? Are all electrical connections correct and tight? SERVICE Inspection and maintenance should be performed at regular intervals and should include the following : Complete cleaning of cabinet, fan wheel, cooling coil, condensate pan and drain and return air grille ( if present). Inspection of panels and sealing unit against air leakage. Adjustment of fan motor, belt, bearings and wheels. Cleaning or replacing of filters. Testing for cooling system leaks. Checking of all electrical connections. 11) that must be lubricated with suitable bearing grease every 3 months. Fig. 11 Fan Shaft, Bearings and Fan Wheel Centering Fan Wheel If fan and fan shaft assembly are not properly centered, blades may scrape against scroll or may create an objectionable whistling noise. It may be necessary to adjust individual fan wheels or move the entire fan shaft. See the following sections. Fan Shaft Position Adjustment Loosen setscrew or locking collar of each fan shaft bearing. Slide shaft into correct position and replace locking collar (Fig. 12). To replace locking collar, push collar up against inner face of the bearing. Turn collar in direction of the fan rotation until tight, and tighten setscrew. Tightening locking collar in direction of fan rotation results in further tightening of collar should setscrew work itself loose.

Fig. 14 Fan Rotation Fig. 12 Fan Shaft Bearing Individual Fan Wheel Adjustment Loosen the two locking bolts holding the fan wheel hub to the shaft. Position fan wheel in center of the fan housing and tighten locking bolts. Clearance between wheel and housing should be the same on both sides. Fan Belts Motor mounting plate and motor support angles are slotted to permit both vertical and horizontal adjustments. Adjust belt(s) for correct deflection by loosening motor mounting bolts, moving motor/plate assembly forward or back and tightening bolts. Press down on belt with one finger midway between fan and motor pulleys to check deflection. For units with motor sizes up to and including 3.0 hp (2.3Kw), correct deflection is 3/16 in. (4.8 mm). For larger motor sizes, correct deflection is 1/8 in (3.2 mm). See Fig. 13 Fan Pulley Alignment Align as follows : 1. Loosen setscrews on pulleys. 2. Align pulleys visually and tighten setscrews on fan pulleys to lock it in place. 3. Use the methods shown in Fig. 15. To check proper pulley alignment. 4. If pulleys are not in correct alignment, loosen the motor holddown bolts and slide the motor axially until the pulleys are aligned. 5. Tighten the motor holddown bolts. Pulley and Drive Adjustments To obtain desired fan speed, refer to fan motor and drive data and adjust pulley as follows: 1. Remove belt from fan motor pulley after loosening motor from motor base. 2. Loosen setscrew in moveable flange of pulley. Screw moveable flange toward fixed flange to increase the fan speed and away from fixed flange to reduce speed. Before tightening setscrew, make certain that setscrew is over nearest flat surface of pulley hub. Fig. 13 Fan Motor Mounting If complete belt replacement is required during servicing, loosen the motor plate mounting bolts, move motor/plate assembly towards the fan pulley and pull the belt(s) off the pulleys. Reverse the procedure with new bolts and readjust deflection. Fan Rotation Correct fan rotation with respect to fan outlet is shown in Fig. 14. To reverse the direction of rotation of a 3phase fan motor, interchange any 2 of the power leads. Refer to the connection Fig. 15 Fan Pulley Adjustments CAUTION Increasing fan speed produces a greater load on motor. Do not exceed rated capacity of motor.

8 Condensate Drains Keep condensate drains free of dirt and foreign matter. ReturnAir Filters Refer to Replacing Filters Section for filter accessibility and removal. Replace with clean filters of the sizes listed in Tables 1A 1D. Coil Removal Remove returnair filters. Remove any heavy dirt that may have accumulated on underside of the coil. Coil can be cleaned more easily with a stiff brush, vacuum cleaner or compressed air when coil is dry. If coil is wet or if water is to be used for cleaning, guard against splashing water on electrical components or damaging surrounding area. Clean coil baffles as applicable and check for tight fit to be sure air does not bypass coil. Cleaning Insulation The insulation contains an immobilized antimicrobial agent that helps prevent the growth of bacteria and fungi. It is recommended to clean the surface of the insulation after every cleaning of the coil by wiping it with watersoap solution.. Replacing Filters Filters can be removed and installed from either side of the unit. 1. Remove the filter side cover. 2. Remove old filters by sliding them out one by one from the filter track. 3. Reverse the procedure to install new filters.
