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 func-

tions 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 per-

forming maintenance or service. More than one discon-

nect 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 us-

ing 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 2

1

⁄

2

ft at front and side of unit for

service clearance and airflow. For units equipped with an econo-

mizer, refer to the accessory installation instructions for ad-

ditional clearance requirements. Be sure floor, wall, or ceil-

ing can support unit weight (Tables 1A-1F). See

Fig. 1A-1C for dimensions.

Uncrating — Move unit as near as possible to final lo-

cation before removing shipping skid.

Remove metal banding, top skid, and plastic wrap. Ex-

amine 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.

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.

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.

*YC and WD option codes for all 034 size units and 008, 010 units with 208/230-1-60

power designate standard motor and high-static drive.

NOTE: See the following table for the sizes available for each 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 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.

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.

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 TXVequalizer 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.

38AQS008/40RMQ008 HEAT PUMP SYSTEM PIPING —

Addition of a liquid solenoid valve (LLSV) is recommended

when the piping system length exceeds 75 feet. The LLSV

must be a bi-flow 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 Com-

ponents 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

flow arrow pointed toward the outdoor unit (in-flow

direction for the heating mode.)

FILTER DRIER REQUIREMENTS FOR 38AQS012/

40RMQ012 AND 38AQS016/40RMQ016 HEAT PUMP

SYSTEMS — The 38AQS012 and 016 units do not in-

clude filter driers. Filter driers must be field-supplied

and installed in 38AQS012/40RMQ012 and 38AQS016/

40RMQ016 systems. The filter driers used with these sys-

tems must be bi-flow types suited for use in heat pump

applications. The Replacement Component Division part num-

bers listed in Fig. 8 are recommended and available for field

installation.

*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.

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.

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.

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.

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.

Fig.9—Typical 40RMS Chilled Water Piping

17

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.

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 con-

nection. See Fig. 11. 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.

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)

For instructions on changing fan rotation, changing drive

speeds and adjusting drives, see Pulley and Drive Adjust-

ment in the Service section.

NOTE: Dimensions in [ ] are in millimeters.

Fig. 10 — Condensate Drains

Fig. 11 — Drain Pan Slope Adjustment

18

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 Tables4-6forunit 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 ter-

minal. 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 (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

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.

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.

FLA — Full Load Amps

MOCP — Maximum Overcurrent Protection

*Motors are designed for satisfactory operation within 10% of nomi-

nal voltages shown. Voltages should not exceed the limits shown in

the Voltage Limits column.

NOTES:

1. Minimum Circuit Amp and MOCP values are calculated in

accordance with NEC (National Electrical Code) (U.S.A. stand-

ard), Article 440.

2. Motor FLA values are established in accordance with UL (Under-

writers’ Laboratories) Standard 1995 (U.S.A. standard).

3. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply volt-

age is greater than 2%.

Use the following formula to determine

the percentage of voltage imbalance.

% Voltage Imbalance

max voltage deviation from average voltage

= 100 x average voltage

EXAMPLE: Supply voltage is 400-3-50.

AB = 393 v

BC = 403 v

AC = 396 v 393 + 403 + 396

Average Voltage = 3

1192

=3

= 397

Determine maximum deviation from average voltage.

(AB) 397 − 393 = 4 v

(BC) 403 − 397 = 6 v

(AC) 397 − 396 = 1 v

Maximum deviation is 6 v.

Determine percent voltage imbalance.

6

% Voltage Imbalance = 100 x 397

= 1.5%

This amount of phase imbalance is satisfactory as it is below the

maximum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than

2%, contact your local electric utility company immediately.

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

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?

Also refer to condensing unit instructions before starting

a split system. A split system start-up checklist is provided

in the back of these instructions.

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.

Fan Motor Lubrication — Fan motor supplied with

unit is permanently lubricated and requires no further

lubrication.

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.

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.

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.

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 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

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 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.

Fig. 18 — Fan Shaft Bearing

Fig. 19 — Fan Motor Mounting

24

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.

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.

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:

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).

Increasing fan speed produces a greater load on mo-

tor. Do not exceed rated capacity of motor.

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.

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.

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.

IMPORTANT: Draining from return line will not

completely 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.

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.

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.

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.

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.

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.

Do not operate unit without air filters.
