SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electric shock, or other occurrences which may injure you or damage your property. Consult qualified installer or service agency for information or assistance. The qualified installer or agency must use only factory-authorized kits or accessories when modifying this product.
Recognize safety information. This is the safety-alert symbol (
). When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury.
Understand the signal words — DANGER, WARNING, and CAUTION. These words are used with the safety-alert symbol. Danger identifies the most serious hazards which will result in severe personal injury or death. Warning indicates a condition that could result in personal injury. Caution is used to identify unsafe practices which would result in minor personal injury or product and property damage.
Installing, starting up, and servicing this equipment can be hazardous due to system pressures, electrical components and equipment location (elevated structures, etc.).
Only trained, qualified installers and service mechanics should install, start up, and service this equipment.
Untrained personnel can perform basic maintenance functions such as cleaning coils, and cleaning and replacing filters. All other operations should be performed by trained service personnel.
When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.
•Follow all safety codes.
•Wear safety glasses and work gloves.
•Use care in handling, rigging, and setting bulky equipment.
Be sure all power to equipment is shut off before performing maintenance or service. More than one disconnect may be present. Failure to do so may result in personal injury or damage to the unit.
PRE-INSTALLATION
1.The power supply (v, ph, and Hz) must correspond to that specified on unit rating plate.
2.The electrical supply provided by the utility must be sufficient to handle load imposed by this unit.
3. Refer to Installation, General section (page 2) and Fig. 1A-1C for locations of electrical inlets, condensate drain, duct connections, and required clearances before setting unit in place.

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 a level, dry storage site free from vibration. Do not remove plastic wrap or skid from unit until final installation.
Rigging — All 40RM Series units can be rigged by using the shipping skid. 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 the accessory installation instructions for additional clearance requirements. Be sure floor, wall, or ceiling can
support unit weight (Tables 1A-1F). See Fig. 1A-1C for dimensions.
Uncrating — Move unit as near as possible to final location before removing shipping skid.
Remove metal banding, top skid, and plastic wrap. Examine unit for shipping damage. If shipping damage is evident, file claim with transportation agency. Remove base skid just prior to actual installation.
Check nameplate information against available power supply and model number description in Fig. 2.
NOTE: Be sure to remove the styrofoam shipping pad from the thermostatic expansion valve (TXV). Verify that it has been removed. See Fig. 3.
Accessories — Refer to instructions shipped with each accessory for specific information.

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 also be 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. 4 for condensate connections for each unit position.
Typical positioning and alternate return air locations are shown in Fig. 4. Alternate return air locations can be used by moving the unit panel from the alternate return air location to the standard return air location. Refer to overhead suspension accessory drawing (Fig. 5) for preferred suspension technique. The unit needs support underneath to prevent sagging.
IMPORTANT: Do NOT attempt to install unit with return air entering top panel of unit. Condensate will not drain from unit.
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 Series units come with standard knockouts for refrigerant and chilled water piping. These knockouts are located on both sides of the unit for installation flexibility. The standard knockouts provide sufficient access to the unit’s coils for all 40RM and some 40RMQ units, however, for 40RMQ016,028 and 40RMS units, additional holes must be field-fabricated to accommodate the piping. See Fig. 6 for the positions and dimensions of the additional access holes required for these units, including hole diameters and drilling dimensions. Recommended access hole use is also listed for all units. Note that Fig. 6 shows the access holes on the controlbox side of the unit; this is the side of the unit with the coil headers, so it is used most often for piping access.
IMPORTANT: Do not bury refrigerant piping underground.
Refrigerant Piping — See Tables 1A, 1B, 1D, 1E for refrigerant pipe connection sizes. For ease in brazing, it is recommended that all internal solder joints be made before unit is placed in final position.
The 40RM and 40RMQ direct-expansion units have internal factory-installed thermostatic expansion valves (TXVs), distributors, and nozzles for use with R-22. See Table 2 for part numbers. Knockouts are provided in the unit corner posts for 40RM and 40RMQ008 and 012 refrigerant piping. The 40RMQ016,024 and 028 units requires additional fieldfabricated piping access holes. See Fig. 6, which also lists recommended knockouts and access holes to use for each 40RM and 40RMQ unit size. Recommended fittings are listed in Table 3.
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 portion of the suction line, outside the unit. See Fig. 7.
NOTE: Be sure to remove the styrofoam shipping pad from the TXV. Verify that it has been removed. See Fig. 3.
IMPORTANT: Never attach the sensor to the suction manifold. Do NOT mount the sensor on a trapped portion of the suction line.

The 40RM Series evaporator coils have a face-split design. Ensure that lower circuit of coil is first on/last off when connected to the condensing unit and/or system controls. See Fig. 8.
External TXV equalizer connections are provided and factory-brazed into the coil suction manifolds.
If suction line must be horizontal, clamp bulb to suction line at least 45 degrees above bottom, at approximately the 4 o’clock or 8 o’clock position. See Fig. 9.
NOTE: The 40RMQ units are supplied with factory-installed thermostatic expansion valves and check valve bypasses. No extra piping connections or kits are required to install the 40RMQ with a 38AQ, 38ARQ, or 38AQS condensing unit in a heat pump system, however, some field-supplied components may be required. See the following two sections.
HEAT PUMP SYSTEM PIPING — Addition of a liquid solenoid valve (LLSV) is recommended. The LLSV must be a bi-flow type suited for use in heat pump systems. Refer to the 38AQ, ARQ, AQS literature for recommended component part numbers. Wire the solenoid valve in parallel with the compressor contactor coil.
The LLSV must be installed at the outdoor unit with the flow arrow pointed toward the outdoor unit (in-flow direction for the heating mode.)
38ARQ DUPLEX/40RMQ024 HEAT PUMP SYSTEM PIPING — Two 38ARQ012 heat pump condensing units may be connected in a duplex arrangement with the 40RMQ024. See Fig. 10. Ensure that the lower circuit of the 40RMQ coil is the first on/last off by connecting to the “A” condensing unit and by configuring the controls so that the “A” condensing unit is the first on/last off.
38ARQ012/38AQS016 DUPLEX/40RMQ028 HEAT PUMP SYSTEM PIPING — One 38ARQ012 and one 38AQS016 heat pump condensing unit may be connected in a duplex arrangement with the 40RMQ028. See Fig. 10. The 40RMQ028 has a 60/40 face split coil. Ensure that the larger coil section (connection “B”, Fig. 8) is connected to the 38QAS016 and the smaller coil section is connected to the 38AQS012. In addition, ensure that the lower circuit of the 40RMQ coil is the first on/last off by connecting to the “A” condensing unit and by configuring (see 38ARQ,AQS installation instructions for more information) the controls so that the “A” condensing unit is the first on/last off.
FILTER DRIER REQUIREMENTS FOR HEAT PUMP SYSTEMS — The 38ARQ and 38AQS units do not include filter driers. Filter driers must be field-supplied and fieldinstalled. The filter driers used with these systems must be bi-flow types suited for use in heat pump applications. Refer to the 38AQ,ARQ,AQS literature for recommended component part numbers. See Fig. 11 for filter drier quantity and location information.
