Efficient operation

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.

Building owners will appreciate the high unit EERs
(Energy Efficiency Ratios) offered by the AR units.
These units provide greater efficiency than similar
units in the marketplace, which translates into yearround operating savings.

Economy — The 0RM 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
0RM models.
High efficiency, precision-balanced fans minimize air
turbulence, surging, and unbalanced operation, cutting
operation expenses.

Controls for performance dependability

The AR 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 ARD0-08 units feature  compressors and 
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
AR units are UL, compliant.

Rugged dependability — The 0RM 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 (0RM0-0) are securely
fastened to the solid steel fan shaft with split collets
and clamp locking devices. Smaller unit sizes have
spider-type bearings.

Innovative Carrier 40RM packaged air
handlers are custom matched to 38AR
condensing units

Coil flexibility — Model 0RM directexpansion coils
have galvanized steel casings; inlet and outlet
connections are on the same end. The coils are
designed for use with R- refrigerant and have /-in.
diameter copper tubes mechanically bonded to
aluminum sine-wave fins.
The coils include matched, factoryinstalled
thermostatic expansion valves (TXVs) with matching
distributor nozzles.

The 0RM 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 0RM
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 buildup of humidity in the room, even during part-load
conditions. Unit sizes of 0 tons and larger feature
dual-circuit coils for improved temperature control.
Standard -in. aluminum washable filters remove dust
and airborne particles from the occupied space for
cleaner air.

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.

ets to support units in horizontal ceiling installations.
CO 2 sensors can be used in conjunction with the econ­
omizer accessoryto help meet indoor air quality require­
ments. The sensor signals the economizer to open when
the CO2 level in the spaceexceedsthe set point. A Carrier
Comfort Systemprogrammable thermostat can be usedto
override the sensorif the outsideair temperature is too high
or too low.

Bold indicates field supplied drive is required.
Plain type indicates standard motor and standard drive.
Underline indicates a different motor and drive combination other than
the standard motor and standard drive combination is required. Refer to
fan motor and drive tables, pages 57-59, to complete selection.
NOTES:
1. Maximum allowable fan speed is 1100 rpm for unit sizes 028 and
034; 1200 rpm for all other sizes.
2. Fan performance is based on deductions for wet coil, clean 1-in.
filters, and unit casing. See table at right for factory-supplied filter
pressure drop.
3. For 50 Hz units, the medium- static drive and standard motor
combination is not available for 016-028 sizes. Use alternate
motor if medium-static drive is required for these sizes.

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

% Voltage Imbalance = 100 x
= 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.

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.

Application data
The air handler fan must always be operating when the
condensingunit is operating.
Ductwork should be sized according to unit size, not
building load. For larger units with two fans, a split duct
transition is recommendedat the fan outlets, but a plenum
can be usedwith slight reduction in external static pressure
capability.
For variable air volume (VAV) systems with supply-to­
return air recycling, usethe equipment room as a return air
plenum.

Operating limits

General
Select equipment to match or to be slightly lessthan peak
load. This providesbetter humidity control, lessunit cycling,
and lesspart-load operation. Equipment should be selected
to perform at no lessthan 300 cfm/ton (40 L/s per kW).
