Efficient operation

Building owners will appreciate the high unit EERs

(Energy Efficiency Ratios) offered by the 38AR units.

These units provide greater efficiency than similar

units in the marketplace, which translates into year-

round operating savings.

Controls for performance dependability

The 38AR condensing units offer the building owner

operating controls and components designed for

performance dependability. The highly efficient

compressors are engineered for long life and

durability. The compressors include overload

protection and vibration isolation for quiet operation.

The high pressure switch protects the entire

refrigeration system from abnormally high operating

pressures. A low pressure switch protects the system

from loss of charge.

The 38ARD014-028units feature 2 compressors and 2

refrigerant circuits that provide continuous air

conditioning and design flexibility.

All units include a crankcase heater to eliminate liquid

slugging at start-up. The latest safety standards for

38AR units are UL, compliant.

Innovative Carrier 40RM packaged air

handlers are custom matched to 38AR

condensing units

The 40RM Series has excellent fan performance,

efficient direct-expansion (DX) coils, a unique

combination of indoor-air quality options, and is easy

to install. Its versatility and state-of-the art features

help to ensure economical performance of the split

system both now and in the future.

Indoor-air quality (IAQ) features —

The unique combination of IAQ features in the 40RM

Series air handlers help to ensure that only clean,

fresh, conditioned air is delivered to the occupied

space.

Direct-expansion (DX) cooling coils prevent the build-

up of humidity in the room, even during part-load

conditions. Unit sizes of 10 tons and larger feature

dual-circuit coils for improved temperature control.

Standard 1-in. aluminum washable filters remove dust

and airborne particles from the occupied space for

cleaner air.

The pitched, non-corroding drain pan can be adjusted

for a right-hand or left-hand connection to suit many

applications and provide positive drainage and prevent

standing condensate.

Economy — The 40RM Series packaged air handlers

have low initial costs, and provide reduced installation

expense and energy-efficient performance.

Quick installation is ensured by the multipoise design.

Units can be installed in either the horizontal or

vertical configuration without modifications. Fan

motors and contactors are prewired and thermostatic

expansion valves (TXVs) are factory-installed on all

40RM models.

High efficiency, precision-balanced fans minimize air

turbulence, surging, and unbalanced operation, cutting

operation expenses.

Rugged dependability — The 40RM series units are

made to last. The die-formed galvanized steel panels

ensure structural integrity under all operating

conditions. Galvanized steel fan housings are securely

mounted to a galvanized steel fan deck. Rugged

pillow-block bearings (40RM014-034) are securely

fastened to the solid steel fan shaft with split collets

and clamp locking devices. Smaller unit sizes have

spider-type bearings.

Coil flexibility — Model 40RM directexpansion coils

have galvanized steel casings; inlet and outlet

connections are on the same end. The coils are

designed for use with R-22 refrigerant and have 3/8-in.

diameter copper tubes mechanically bonded to

aluminum sine-wave fins.

The coils include matched, factoryinstalled

thermostatic expansion valves (TXVs) with matching

distributor nozzles.

Easier installation and service —

The multipoise design and component layout ensures

quick unit installation and operation. Units can be

converted from horizontal to vertical operation by

simply repositioning the unit. Drain pan connections

are duplicated on both sides of the unit. The filters,

motor, drive, TXVs, and coil connections are all easily

accessed by removing side panels.

Refrigerant piping

IMPORTANT: Do not bury refrigerant piping

underground.

It is recommended that the refrigerant piping for all

commercial split systems include a liquid line

solenoid valve, a liquid line filter drier and a sight

glass.

For refrigerant lines longer than 75 lineal ft, a

liquid line solenoid valve installed at the indoor

unit and a suction accumulator are required. Refer

to the Refrigerant Specialties

Part Numbers table.

Options and accessories

Factory-installed options

Alternate fan motors and drives are availableto pro-

vide the widest possiblerange of performance.

Field-installed accessories

Electric resistance heat coils havean open-wire design

and are mounted in a rigid frame. Safety cutouts for high

temperature conditions are standard. Terminal block for

single-point power connection is included.

Economizer (enthalpy contr olled) provides ventilation

air and ``free'' cooling if outside ambient temperature and

humidity are suitable.Can also be used with CO

sensors

to help meet indoor air quality requirements.

Discharge plenum directs the air discharge directly into

the occupiedspace;integral horizontal and vertical louvers

enable redirection of airflow. Accessory is available un-

painted or painted. Field assemblyrequired.

Standard units available from the factory are in

Double skin.

Return-air grille provides a protective barrier over the

return-air opening and givesa finished appearanceto units

installed in the occupied space. Accessoryis availableun-

painted or painted.

Subbase provides a stable,raised platform and room for

condensatedrain trap connectionfor verticalfloor-mounted

units. Accessoryis availableunpainted or painted.

Over head suspension package includes necessarybrack-

ets to support units in horizontal ceiling installations.

sensors can be used in conjunction with the econ-

omizer accessoryto help meet indoor air quality require-

ments. The sensor signalsthe economizer to open when

the CO

levelin the spaceexceedsthe setpoint. A Carrier

Comfort Systemprogrammable thermostat can be usedto

overridethe sensorif the outsideair temperatureistoo high

or too low.

Carrier's line of ther mostats provide both program-

mable and non-programmable capability with the new

Debonair line of commercial programmable thermostats,

the TEMP System controls offer communication capabil-

ity with stagedheatingandcooling, the Commercial Elec-

tronic thermostats provide 7-day programmablecapability

for economicalapplications,while the Non-Programmable

thermostatsoffer a multitude of stagedheating and cooling

subbaseoptions.

Condensate drain trap includesan overflow shutoff switch

that can be wired to turn off the unit if the trap becomes

plugged. Kit also includesa wire harnessthat can be con-

nected to an alarm if desired. The transparent trap is de-

signedfor easyserviceand maintenance.

FLA — Full Load Amps

MOCP — Maximum Overcurrent Protection

*Motors are designed for satisfactory operation within 10% of nominal voltages

shown. Voltages should not exceed the limits shown in the Voltage Limits column.

NOTES:

1. Minimum circuit amps (MCA) and MOCP values are calculated in accordance

with NEC (National Electrical Code) (U.S.A. standard), Article 440.

2. Motor FLA values are established in accordance with UL (Underwriters’ Labo-

ratories) Standard 1995 (U.S.A. standard).

3. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage 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

= 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.

% Voltage Imbalance = 100 x 397

= 1.5%

This amount of phase imbalance is satisfactory because it is below the maxi-

mum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2%, con-

tact your local electric utility company immediately.

*Values shown are for single-point connection of electric heat accessory and air

handler.

†Single-phase motors. All other motors are 3-phase.

NOTES:

1. Electrical resistance heaters are rated at 240 v, 480 v, or 575 v. To determine

heater capacity (kW) at unit nameplate multiply the 240-v, 480-v, or 575-v ca-

pacity (kW) by the factor shown in the table below for the unit voltage.

2. The following equation converts kW of heat energy to Btuh:

kW x 3,412 = Btuh.

3. Heater contactor coils are 24 v and require 8 va holding current.

4. Electric heaters are tested and ETL approved at maximum total external static

pressure of 1.9 in. wg.

5. MCA and MOCP values apply to both standard and alternate factory-supplied

motors.
