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, 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.
PRE-INSTALLATION
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.
Accessories — Refer to instructions shipped with each
accessory for specific information.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Fig. 2 — Model Number Nomenclature
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. 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.
LEGEND
Accessory Line
Alternate Air Intake and Discharge
Air Intake and Discharge
Fig. 3 — Typical Unit Positioning
IMPORTANT: Do NOT attempt to install unit with
return air entering top panel of unit. Condensate will
not drain from unit.
11
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 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 unit requires additional field-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 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. 5.
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
and 40RMS units, additional holes must be field-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.

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 first 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 field supplied components may be
required. See the following two sections.

*See Fig. 4 for access hole location by number.
†Fittings are listed in order from header or tee stub connection out to access hole in corner support post.
To size, design, and install chilled water piping, consult
the Carrier System Design manual. See Fig. 9 for an example of a typical installation. Recommended fittings are listed
in Table 3.
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 header, respectively. See the Service
section for information on preventing coil freeze-up during
winter.
Chilled Water Piping — See Tables 1C and 1F for
chilled water connection sizes. For ease in brazing, it is recommended that all internal solder joints be made before unit
is placed in final position.
Knockouts are provided in the unit corner posts for 40RM
and 40RMQ refrigerant piping; additional field-fabricated access holes are required for 40RMS chilled water piping. See
Fig. 4, which lists recommended knockouts and access holes
to use for each 40RMS unit size.

outlet at both ends of the unit, push drain pan down in
the slots near the drain connection, and up in the slots
on the opposite end. Retighten screws. The pan should
have a pitch of at least 1⁄4-in. over its length toward the drain
connection.
Condensate Drain — Install a trapped condensate drain
line to unit connection as shown in Fig. 10. The unit drain
connection is a PVC stub. See Fig. 11. Some areas may require an adapter to connect to either galvanized steel or
copper pipe. For these applications, install a field-supplied
threaded PVC adapter.
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 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 pressure created by fans, preventing complete drainage. Conditions will worsen as filters become dirty.
Install clean-out plugs in trap. Pitch drain line downward
to an open floor drain or sump. Provide service clearance
around drain line to permit removal of unit 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. 11. Loosen the 2 screws next to the drain
Fan Motors and Drives — Motor and drive packages are factory installed in all units. The standard motor
and drive packages consist of the following items:
1 — fan motor
1 — adjustable motor pulley
1 — fan pulley
1 —fan belt (40RM007-016, 40RMQ008-016, 40RMS
008-016 units)
2 —matched fan belts (40RM024-034, 40RMS024-034
units)
For instructions on changing fan rotation, changing drive
speeds and adjusting drives, see Pulley and Drive Adjustment in the Service section.

230-v, 3-ph, 60 Hz operation. Rewire the motor according to
the diagram plate on the motor. After reconfiguring the motor, place the sticker specifying 230-v operation (supplied in
installation packet) over the 460-v sticker on the units corner post.
Fan motors are factory installed on all units. Indoor-fan
contactors are located in the fan contactor box behind the
side access panel (see Fig. 12 and 13). Wire the thermostat
to the 24-v control circuit terminal block located in the side
of the fan contactor control box, according to Fig. 14 or the
unit label diagram. If the air handler is part of a split system,
complete the wiring from the condensing unit to the thermostat shown in Fig. 14.
Power Supply and Wiring — Check the unit data
plate to ensure that available power supply matches electrical characteristics of the unit. Provide a disconnect switch of
size required to provide adequate fan motor starting current.
See Tables 4 - 6 for unit electrical data.
Install disconnect switch and power wiring in accordance
with all applicable local codes. See Fig. 12-14 and the unit
label diagram. For units with motor sizes less than 5 Hp
(3.7 kW), connect power wiring to unit with no. 10 ring terminal. For units with motor sizes of 5 Hp (3.7 kW) or more,
connect power wiring with 1⁄4-in. ring terminal.
The 40RM, 40RMQ and 40RMS size 007-016 units (except 40RM016 with YC or WD option) that have motors wired
for 460-v, 3-ph, 60 Hz operation can be field-converted to
105° C 600V

Connecting Ductwork — Refer to the Carrier System Design Manual for the recommended design and layout
of ductwork. Figure 15 shows recommended duct connection to units with 2 fans.
DISCHARGE CONNECTIONS — Duct flanges are factory
supplied; they are shipped inside the unit attached to the hairpin end of the coil tube sheet for field installation. Using the
existing screws, install the duct flanges on the unit’s fan deck.
Each fan discharge requires 2 flanges; each flange must be
bent in the middle to conform to the discharge opening. See
Fig. 16. After flanges are installed, connect them to the supply duct using a canvas connection to prevent vibration. It is
important that this connection be properly fabricated to prevent high air friction losses and air noise.
RETURN CONNECTION — When using return-air ductwork, route return-air duct to the unit’s return air inlet near
the filter rack, using a canvas connection to prevent transmission of unit vibration. If the duct blocks off the unit’s
access panel, provide a slip joint in the ductwork to permit
removal for servicing.
OUTDOOR-AIR INLET CONNECTION — Connect outdoorair inlet to field-installed accessory economizer. Refer to economizer Installation Instructions.
Return-Air Filters — Type and size of filters are
shown in Tables 1A-1F and are factory-supplied and installed. In all units with 2 fans, a filter replacement tool (hook)
is shipped inside the unit for field use when replacing filters.
See the Service section for instructions on filter element
replacement.

START-UP
Fan Motor Lubrication — Fan motor supplied with
unit is permanently lubricated and requires no further
lubrication.
Before starting unit, check the following and correct as
necessary:
• Is unit solidly supported?
• Is fan adjusted for speed and pulley alignment?
• Are pulleys, motor, and bearings securely mounted?
• Are there any loose parts that will rattle or vibrate?
• Is condensate drain pan pitched for correct drainage?
• Are coil baffle plates tight against coil to prevent air
bypass?
• Are all panels securely fastened?
• Are all electrical connections correct and tight?
Fan Shaft Bearings — Bearings on 007-012 size units
are sealed, permanently lubricated bearings that require no
further lubrication. Size 014-034 units have pillow-block bearings (Fig. 17) that must be lubricated with suitable bearing
grease approximately every 3 months. See Table 7 for suitable lubricants.

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, heating coils, and return-air grille
(if present).
• Inspection of panels and sealing of unit against air
leakage.
• Adjustment of fan motor, belt, bearings, and wheels.
• Cleaning or replacement of filters.
• Testing for cooling/heating system leaks.
• Checking of all electrical connections.
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 a 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 and coil compartment must be sealed tightly
after service to prevent air from bypassing the cooling coil.

Individual Fan Wheel Adjustment — Loosen the
bly 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 entire fan
shaft. See the following two sections.
2 locking bolts holding fan wheel hub to shaft. See Fig. 17.
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 Shaft Position Adjustment — Loosen setscrew or locking collar of each fan shaft bearing. Slide shaft
into correct position and replace locking collar (Fig. 18). To
replace locking collar, push collar up against inner face of
bearing. Turn collar in direction of 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.
Fan Belts — Motor mounting plate and motor support
angles are slotted to permit both vertical and horizontal
adjustment. Adjust belt(s) for correct deflection by loosening motor plate mounting bolts, moving motor/plate assembly forward or back, and retightening 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 3.7 Hp (2.76 kW), correct deflection is 3⁄16-in.
(4.8 mm) For larger motor sizes, correct deflection is 1⁄8-in.
(3.2 mm). See Fig. 19.
NOTE: The 028 and 034 size units with 60 Hz motors are
shipped with an extra set of matching belts. Use the preinstalled belts or extra belts depending on the adjustable
pulley setting.
If complete belt replacement is required during servicing, loosen the motor plate mounting bolts (Fig. 19), move
motor/plate assembly towards fan pulley, and pull belt(s) off
pulleys. Reverse the procedure with new bolts and readjust
deflection.
Fan Rotation — Correct fan rotation with respect to
fan outlet is shown in Fig. 20.
To reverse the direction of rotation of a 3-phase fan motor, reverse any 2 of the power leads. Refer to the connection
diagram on the inside of motor terminal box cover for proper
reversing procedure of single-phase motor.

Fan Pulley Alignment — Align as follows:
1. Loosen setscrews on pulleys.
2. Align pulleys visually and tighten setscrews on fan pulley to lock it in place.
3. Use the methods shown in Fig. 21 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 motor holddown bolts.
Fig. 21 — Fan Pulley Adjustments
Alternative freeze protection methods follow:
• Circulate hot water within the water coil’s supply main or
supplementary space heating.
• Close off supply lines to unit and open a union or fieldsupplied drain valve in the return line.
Pulley and Drive Adjustment — To obtain desired
fan speed, refer to the fan motor and drive data in
Tables 8A-10D and adjust fan motor pulley as follows:
IMPORTANT: Draining from return line will not
completely drain water from coils.
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. 21).
After draining as much water as possible from coils, add
sufficient antifreeze to prevent residual water in the coil
from freezing.
• Add a sufficient quantity of non-corrosive antifreeze to the
entire system to prevent all water within the system from
freezing.
Coil Removal — Remove unit panels and corner posts
as required. Disconnect coil connections and remove fastening screws. Remove coil through end or side sections of unit.
Increasing fan speed produces a greater load on motor. Do not exceed rated capacity of motor.
Cleaning Cooling Coil — Remove return-air filters.
Remove any heavy dirt that may have accumulated on underside of 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.
Condensate Drains — Keep condensate drains free of
dirt and foreign matter.
Return-Air Filters — Refer to Replacing Filters section, page 39, for filter accessibility and removal. Replace
with clean filters of the sizes listed in Tables 1A-1F.
Cleaning Insulation — The insulation contains an
Chilled Water Coil Freeze Protection — Shut off
water supply to unit. Remove side panel of unit and remove
vent and drain plugs in top and bottom of coil header. Drain
coil and blow out remaining water. Reinstall plugs and side
panel.

Legend and Notes for Tables 10C and 10D
Replacing Filters — Filters can be removed and installed from either side of the unit. Install new filters in units
that have one fan as follows:
1. Remove the side access panel (retain screws).
2. Remove the filter retainer clip.
3. Remove old filters by tilting them and lifting them out of
the filter track. See Fig. 12 and 22.
4. Reverse the procedure to install new filters.
LEGEND
ESP — External Static Pressure
NOTES:
1. Maximum allowable fan speed is 18.3 r/s for unit sizes 028 and
034; 20 r/s for all other sizes.
2. Fan performance is based on deductions for wet coil, clean 51-mm
filters, and unit casing. See right for factory-supplied filter pressure drop.
3. Refer to fan motor and drive tables for additional data.
To install new filters in larger units that have 2 fans, follow the preceding steps, but use the factory-supplied
filter hook to slide filters within reach for removal. The
filter hook is shipped inside the unit in the baserail.
