SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment can be hazardous due to system pressures, electrical components and equipment location (elevated structures, etc.).
Only trained, quali®ed 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
®lters. 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.
PRE-INSTALLATION
Moving and Storage Ð 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 ®nal installation.
Rigging Ð 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 ®nal placement; damage to bottom panels can result. Use slings and spreader bars as applicable to lift unit.
INSTALLATION
General Ð Allow 21¤2 ft at front and side of unit for service clearance and air¯ow. For units equipped with an economizer, refer to the accessory installation instructions for additional clearance requirements. Be sure ¯oor, wall, or ceiling can support unit weight (Tables 1A-1F). See Fig. 1A-1C for dimensions.
Uncrating Ð Move unit as near as possible to ®nal location before removing shipping skid.
Remove metal banding, top skid, and plastic wrap. Examine unit for shipping damage. If shipping damage is evident, ®le claim with transportation agency. Remove base skid just prior to actual installation.

Fig. 2 Ð Model Number Nomenclature
Unit Positioning Ð The unit can be mounted on the ¯oor 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. 3 for condensate connections for each unit position.
Typical positioning and alternate return air locations are shown in Fig. 3. Alternate return air locations can be used by moving the unit panel from the alternate return air location to the standard return air location.

Unit Isolation Ð Where extremely quiet operation is essential, install isolators between ¯oor 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 Ð
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 ¯exibility. The standard knockouts provide sufficient access to the unit's coils for all 40RM and some 40RMQ units, however, for 40RMQ016 and 40RMS units, additional holes must be ®eld-fabricated to accommodate the piping. See Fig. 4 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. 4 shows the access holes on the control-box side of the unit; this is the side of the unit with the coil headers, so it is used most often for piping access.
Refrigerant Piping Ð 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 ®nal 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 unit requires additional ®eld-fabricated piping access holes. See Fig. 4, which also lists recommended knockouts and access holes to use for each 40RM and 40RMQ unit size. Recommended ®ttings 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. 5.

IMPORTANT: Never attach the sensor to the suction manifold. Do NOT mount the sensor on a trapped portion of the suction line.
40RM Series evaporator coils have a face-split design. Ensure that lower circuit of coil is ®rst on/last off when connected to the condensing unit and/or system controls. See Fig. 6.
External TXV equalizer connections are provided and factorybrazed 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. 7.
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 38AQS condensing unit in a heat pump system, however, some ®eld supplied components may be required. See the following two sections.

* Feeder tube size is 1¤4 in. (6.35 mm).
NOTE: Hot gas bypass applications require ®eld-supplied auxiliary side connector.
38AQS008/40RMQ008 HEAT PUMP SYSTEM PIPING Ð Addition of a liquid solenoid valve (LLSV) is recommended when the piping system length exceeds 75 feet. The LLSV must be a bi-¯ow type suited for use in heat pump systems. The recommended valve is Sporlan model CB14S2 (5/8-in. ODF, 7/8-in. ODM) available from the Replacement Components Division as part number EF23JS-214. This solenoid valve requires Sporlan part no. MKC-2 coils that must be purchased locally. Wire the solenoid valve in parallel with the compressor contactor coil.
The LLSV must be installed at the outdoor unit with the ¯ow arrow pointed toward the outdoor unit (in-¯ow direction for the heating mode.)
FILTER DRIER REQUIREMENTS FOR 38AQS012/ 40RMQ012 AND 38AQS016/40RMQ016 HEAT PUMP SYSTEMS Ð The 38AQS012 and 016 units do not include ®lter driers. Filter driers must be ®eld-supplied and installed in 38AQS012/40RMQ012 and 38AQS016/ 40RMQ016 systems. The ®lter driers used with these systems must be bi-¯ow types suited for use in heat pump applications. The Replacement Component Division part numbers listed in Fig. 8 are recommended and available for ®eld installation.
