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 arrange-  
ment with return air entering horizontally and the supply air  
discharging horizontally. When applying the unit in a horizon-  
tal 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.

Alternate Air Intake and Discharge  
Air Intake and Discharge  
Fig. 4 — Typical Unit Positioning  
IMPORTANT: Do NOT attempt to install unit with return  
air entering top panel of unit. Condensate will not drain  
from unit.  
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.  
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.  
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 so-  
lenoid 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 com-  
pressor 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 installa-  
tion 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 field-  
installed. 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.  
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 re-  
quired 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 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: 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 rec-  
ommended that all internal solder joints be made before unit is  
placed in final position.  
The 40RM and 40RMQ direct-expansion units have inter-  
nal 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 field-  
fabricated piping access holes. See Fig. 6, which also lists rec-  
ommended 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.

*See Fig. 6 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. 12 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 recom-  
mended 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 ac-  
cess holes are required for 40RMS chilled water piping. See  
Fig. 6, which lists recommended knockouts and access holes to  
use for each 40RMS unit size.  
Fig. 12 — Typical 40RMS Chilled Water Piping  
19  
See Fig. 14. 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  
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. 13. The unit drain con-  
nection is a PVC stub. See Fig. 14. 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. Condi-  
tions 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.  
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  
(40RM007-012,  
40RMQ008-012,  
40RMS008-012 units)  
2 — matched fan belts (40RM014-034, 40RMS014-034,  
40RMQ014-028 units)  
For instructions on changing fan rotation, changing drive  
speeds and adjusting drives, see Pulley and Drive Adjustment  
in the Service section.

460-v, 3-ph, 60 Hz operation can be field-converted to  
208/230-v, 3-ph, 60 Hz operation. Rewire the motor according  
to the diagram plate on the motor. After reconfiguring the mo-  
tor, mark the motor specifying 208-v or 230-v operation replac-  
ing the 460-v sticker information on the units’ corner post.  
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.  
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. 15 and 16). Wire the thermostat to the  
24-v control circuit terminal block located in the side of the fan  
contactor control box, according to Fig. 17 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. 17.  
Install disconnect switch and power wiring in accordance  
with all applicable local codes. See Fig. 15-17 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 termi-  
nal. For units with motor sizes of 5 Hp (3.7 kW) or more, con-  
nect power wiring with 1/4-in. ring terminal.

Connecting Ductwork — Refer to the Carrier System  
Design Manual for the recommended design and layout of  
ductwork. Figure 18 shows recommended duct connection to  
units with 2 fans.  
Do not operate unit without ductwork or discharge plenum  
unless fan speed has been adjusted for external static pres-  
sure of zero in. wg. Failure to do so may result in motor  
overload.  
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. Us-  
ing 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. 19. After flanges are installed, connect them to the supply  
duct using a canvas connection to prevent vibration. It is im-  
portant that this connection be properly fabricated to prevent  
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 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 outdoor-  
air inlet to field-installed accessory economizer. Refer to  
Economizer Installation Instructions.

START-UP  
Fan Shaft Bearings — Bearings on size 007-012 units  
are sealed, permanently lubricated bearings that require no  
further lubrication. Size 014-034 units have pillow-block bear-  
ings (Fig. 20) that must be lubricated with suitable bearing  
grease approximately every 3 months. See Table 7 for suitable  
lubricants.  
Before starting unit, check the following and correct as nec-  
essary:  
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?

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 insu-  
lation 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.  
Fig. 20 — Fan Shaft, Bearings, and Fan Wheel  
(Typical)  
Fan Motor Lubrication — Fan motor supplied with  
unit is permanently lubricated and requires no further  
lubrication.  
25  
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 neces-  
sary 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. 20.  
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. 21). To re-  
place locking collar, push collar up against inner face of bear-  
ing. Turn collar in direction of fan rotation until tight, and tight-  
en setscrew. Tightening locking collar in direction of fan rota-  
tion results in further tightening of collar should setscrew work  
itself loose.  
Fan Belts — Motor mounting plate and motor support an-  
gles are slotted to permit both vertical and horizontal adjust-  
ment. 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 fin-  
ger midway between fan and motor pulleys to check deflection.  
For units with motor sizes up to and including 3.7 Hp  
3
(2.76 kW), correct deflection is /16-in. (4.8 mm). For larger  
motor sizes, correct deflection is 1/8-in. (3.2 mm). See Fig. 22.  
NOTE: The 028 and 034 size units with 60 Hz motors  
(standard or medium static drive) are shipped with an extra set  
of 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. 22), 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. 23.  
To reverse the direction of rotation of a 3-phase fan motor,  
reverse any 2 of the power leads. Refer to the connection dia-  
gram on the inside of motor terminal box cover for proper re-  
versing procedure of single-phase motor.

Fig. 22 — Fan Motor Mounting  
26  
Fig. 23 — Fan Rotation  
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. 24 to check proper pulley  
alignment.  
Fig. 24 — 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.  
5. Tighten motor holddown bolts.  
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 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-  
11D and adjust fan motor 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. Be-  
fore tightening setscrew, make certain that setscrew is  
over nearest flat surface of pulley hub (Fig. 24).  
IMPORTANT: Draining from return line will not com-  
pletely drain water from coils.  
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.  
Increasing fan speed produces a greater load on motor. Do  
not exceed rated capacity of motor.  
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.  
Condensate Drains — Keep condensate drains free of  
dirt and foreign matter.  
Cleaning Cooling Coil — Remove return-air filters.  
Remove any heavy dirt that may have accumulated on under-  
side 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 splash-  
ing 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.  
Return-Air Filters — Refer to Replacing Filters section  
for filter accessibility and removal. Replace with clean filters of  
the sizes listed in Tables 1A-1F.  
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.  
Cleaning Insulation — The insulation contains an im-  
mobilized antimicrobial agent that helps prevent the growth of  
bacteria and fungi. Clean the inner surface of the insulation  
according to the separate maintenance instructions shipped  
with the unit.  
27  
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 (see Fig. 25).  
3. Remove old filters by lifting and tilting them out of the  
filter track. See Fig. 15 and 26.  
4. Reverse the procedure to install new filters.  
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 filter track.  
Do not operate unit without air filters.
