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 sup-  
ply 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 con-  
densate disposal. See Fig. 3 for condensate connections for  
each unit position.  
LEGEND  
Accessory Line  
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.

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 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 knock-  
outs and access holes to use for each 40RM and 40RMQ  
unit size. Recommended fittings are listed in Table 3.  
Refrigerant and Chilled Water Piping Access —  
The 40RM Series units come with standard knockouts for  
refrigerant and chilled water piping. These knockouts are lo-  
cated 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. Rec-  
ommended 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.  
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 suc-  
tion line, outside the unit. See Fig. 5.

IMPORTANT: Never attach the sensor to the suction  
manifold. Do NOT mount the sensor on a trapped por-  
tion of the suction line.  
40RM Series evaporator coils have a face-split design. En-  
sure that lower circuit of coil is first on/last off when con-  
nected to the condensing unit and/or system controls. See  
Fig. 6.  
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. 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.

†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 ex-  
ample of a typical installation. Recommended fittings are listed  
in Table 3.  
Chilled Water Piping — See Tables 1C and 1F for  
chilled water connection sizes. For ease in brazing, it is rec-  
ommended that all internal solder joints be made before unit  
is placed in final position.  
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.  
Knockouts are provided in the unit corner posts for 40RM  
and 40RMQ refrigerant piping; additional field-fabricated ac-  
cess 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 14-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 re-  
quire 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 drain-  
age. Conditions will worsen as filters become dirty.  
Fan Motors and Drives — Motor and drive pack-  
ages 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)  
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.  
For instructions on changing fan rotation, changing drive  
speeds and adjusting drives, see Pulley and Drive Adjust-  
ment in the Service section.  
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 con-  
nection. See Fig. 11. Loosen the 2 screws next to the drain

230-v, 3-ph, 60 Hz operation. Rewire the motor according to  
the diagram plate on the motor. After reconfiguring the mo-  
tor, place the sticker specifying 230-v operation (supplied in  
installation packet) over the 460-v sticker on the units cor-  
ner post.  
Power Supply and Wiring — Check the unit data  
plate to ensure that available power supply matches electri-  
cal 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.  
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 ther-  
mostat shown in Fig. 14.  
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 ter-  
minal. For units with motor sizes of 5 Hp (3.7 kW) or more,  
1
connect power wiring with 4-in. ring terminal.  
The 40RM, 40RMQ and 40RMS size 007-016 units (ex-  
cept 40RM016 with YC or WD option) that have motors wired  
for 460-v, 3-ph, 60 Hz operation can be field-converted to

Connecting Ductwork — Refer to the Carrier Sys-  
tem Design Manual for the recommended design and layout  
of ductwork. Figure 15 shows recommended duct connec-  
tion to units with 2 fans.  
DISCHARGE CONNECTIONS — Duct flanges are factory  
supplied; they are shipped inside the unit attached to the hair-  
pin 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 sup-  
ply duct using a canvas connection to prevent vibration. It is  
important that this connection be properly fabricated to pre-  
vent high air friction losses and air noise.  
RETURN CONNECTION — When using return-air duct-  
work, route return-air duct to the unit’s return air inlet near  
the filter rack, using a canvas connection to prevent trans-  
mission 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 outdoor-  
air inlet to field-installed accessory economizer. Refer to econo-  
mizer Installation Instructions.  
Return-Air Filters — Type and size of filters are  
shown in Tables 1A-1F and are factory-supplied and in-  
stalled. 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:  
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 bear-  
ings (Fig. 17) that must be lubricated with suitable bearing  
grease approximately every 3 months. See Table 7 for suit-  
able lubricants.  
• 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?

SERVICE  
Inspection and maintenance should be performed at  
regular intervals and should include the following:  
• Complete cleaning of cabinet, fan wheel, cooling coil, con-  
densate 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 serv-  
ice 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.

Centering Fan Wheel — If fan and fan shaft assem-  
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.  
Individual Fan Wheel Adjustment — Loosen the  
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 set-  
screw 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 loosen-  
ing motor plate mounting bolts, moving motor/plate assem-  
bly 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  
3
including 3.7 Hp (2.76 kW), correct deflection is 16-in.  
(4.8 mm) For larger motor sizes, correct deflection is 18-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 pre-  
installed belts or extra belts depending on the adjustable  
pulley setting.  
If complete belt replacement is required during serv-  
icing, 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 mo-  
tor, 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 pul-  
ley to lock it in place.  
3. Use the methods shown in Fig. 21 to check proper pulley  
alignment.  
Fig. 21 — Fan Pulley Adjustments  
4. If pulleys are not in correct alignment, loosen the motor  
holddown bolts and slide the motor axially until the pul-  
leys are aligned.  
Alternative freeze protection methods follow:  
5. Tighten motor holddown bolts.  
• 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 field-  
supplied 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 mo-  
tor from motor base.  
2. Loosen setscrew in moveable flange of pulley. Screw move-  
able flange toward fixed flange to increase the fan speed  
and away from fixed flange to reduce speed. Before tight-  
ening 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 fasten-  
ing screws. Remove coil through end or side sections of unit.  
Increasing fan speed produces a greater load on mo-  
tor. Do not exceed rated capacity of motor.  
Cleaning Cooling Coil — Remove return-air filters.  
Remove any heavy dirt that may have accumulated on un-  
derside 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 dam-  
aging 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 sec-  
tion, 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  
immobilized antimicrobial agent that helps prevent the  
growth of bacteria and fungi. Clean the inner surface of the  
insulation according to the separate maintenance instruc-  
tions shipped with the unit.  
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 in-  
stalled 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.

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 pres-  
sure drop.  
3. Refer to fan motor and drive tables for additional data.  
To install new filters in larger units that have 2 fans, fol-  
low 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.
