Product Data
FEATURES AND BENEFITS
AVAILABLE SIZES:
Nominal sizes are available from 018 through 060 to meet the
needs of residential and light commercial applications.
CERTIFICATION:
All models are listed with UL and NOM.
ELECTRICAL RANGE:
Units offered in single phase 208/230v are 018--060 and three
phase 208/230v in 036, 048 and 060.
FAN MOTOR:
The totally enclosed fan motor provides greater reliability under
adverse conditions and dependable performance for many years.
The permanent split capacitor type motor was designed for
optimum efficiency. The motor was then qualified under extreme
conditions to help ensure a long, reliable life.
CABINET:
A weather protective cabinet of prepainted steel is protected
underneath by a galvanized coating and treated with a layer of zinc
phosphate for a finish that will last for many years. All screws on
cabinet exterior are coated for a long--lasting, rust--resistant, quality
appearance.
UNIT DESIGN:
The copper tube, enhanced sine wave, aluminum fin coil is
designed for optimum heat transfer. Vertical air discharge carries
sound and hot condenser air up and away from adjacent patio areas
and foliage. The base pan is designed for easy removal of water,
dirt, and leaves.
COMPRESSOR:
Each compressor is protected with internal temperature-- and
current--sensitive overloads. An internal pressure relief valve
provides high pressure protection to the refrigerant system. For
improved serviceability, all models are equipped with a compressor
terminal plug.
SERVICE VALVES:
Both service valves are brass, front seating type with sweat
connections. Valves are externally located so refrigerant tube
connections can be made quickly and easily. Each valve has a
service port for ease of checking operating refrigerant pressures.
SERVICEABILITY:
One access panel provides access to electrical controls. Removal of
top gives access to fan motor, compressor, and condenser coil.

{ Required for Low---Ambient Controller (full modulation feature) MotorMasterr Control.
Accessory Description and Usage (Listed Alphabetically)
1. Ball--Bearing Fan Motor
A fan motor with ball bearings which permits speed reduction
while maintaining bearing lubrication.
Usage Guideline:
Required on all units when MotorMasterr is used.
2. Compressor Start Assist -- Capacitor and Relay
Start capacitor and relay gives a ”hard” boost to compressor motor
at each start up.
Usage Guideline:
Required for reciprocating compressors in the
following applications:
Long line
Low ambient cooling
Hard shut off expansion valve on indoor coil
Liquid line solenoid on indoor coil
Required for single--phase scroll compressors in the
following applications:
Long line
Low ambient cooling
Suggested for all compressors in areas with a history of
low voltage problems.
3. Compressor Start Assist — PTC Type
Solid state electrical device which gives a ”soft” boost to the
compressor at each start--up.
Usage Guideline:
Suggested in installations with marginal power supply.
4. Crankcase Heater
An electric resistance heater which mounts to the base of the
compressor to keep the lubricant warm during off cycles. Improves
compressor lubrication on restart and minimizes the chance of
liquid slugging.
Usage Guideline:
Required in low ambient cooling applications.
Required in long line applications.
Suggested in all commercial applications.
5. Cycle Protector
The cycle protector is designed to prevent compressor short
cycling. This control provides an approximate 5--minute delay after
power to the compressor has been interrupted for any reason,
including power outage, protector control trip, thermostat jiggling,
or normal cycling.
6. Evaporator Freeze Thermostat
An SPST temperature--actuated switch that stops unit operation
when evaporator reaches freeze--up conditions.
Usage Guideline:
Required when low ambient kit has been added.
7. Low--Ambient Pressure Switch Kit
A long life pressure switch which is mounted to outdoor unit
service valve. It is designed to cycle the outdoor fan motor in order
to maintain head pressure within normal operating limits
(approximately 100 psig/689.5 KpA to 225 psig/1551.3 KpA. The
control will maintain working head pressure at low--ambient
temperatures down to 0_F (--18_C)when properly installed.
Usage Guideline:
A Low--Ambient Pressure Switch or MotorMasterr
Low--Ambient Controller must be used when cooling operation is
used at outdoor temperatures below 55_F (12.8_C).
8. MotorMasterr Low--Ambient Controller
A fan--speed control device activated by a temperature sensor,
designed to control condenser fan motor speed in response to the
saturated, condensing temperature during operation in cooling
mode only. For outdoor temperatures down to --20_F (--28.9_C), it
maintains condensing temperature at 100_F ±10_F (37.8_C ±
5.5_C).
Usage Guideline:
A MotorMasterr Low Ambient Controller or
Low--Ambient Pressure Switch must be used when
cooling operation is used at outdoor temperatures
below 55_F (12.8_C).
Suggested for all commercial applications.
9. Outdoor Air Temperature Sensor
Designed for use with Carrier Thermostats listed in this
publication. This device enables the thermostat to display the
outdoor temperature. This device also
is required to enable special thermostat features such as auxiliary
heat lock out.
Usage Guideline:
Suggested for all Carrier thermostats listed in this
publication.

Accessory Description and Usage (Listed Alphabetically) (Continued)
13. Time--Delay Relay
An SPST delay relay which briefly continues operation of indoor
blower motor to provide additional cooling after the compressor
cycles off.
NOTE: Most indoor unit controls include this feature. For those
that do not, use the guideline below.
Usage Guideline:
For improved efficiency ratings for certain
combinations of indoor and outdoor units. Refer to
ARI Unitary Directory.
14. Winter Start Control
This control is designed to alleviate nuisance opening of the
low--pressure switch by bypassing it for the first 3 minutes of
operation.
38CKD
10. Sound Hood
Wraparound sound reducing cover for the compressor. Reduces the
sound level by about 2 dBA.
Usage Guideline:
Suggested when unit is installed closer than 15 ft (4.57 m) to
quiet areas, bedrooms, etc.
Suggested when unit is installed between two houses less
than 10 ft (3.05 m) apart.
11. Support Feet
Four stick--on plastic feet that raise the unit 4 in. (101.6 mm) above
the mounting pad. This allows sand, dirt, and other debris to be
flushed from the unit base, minimizing corrosion.
Usage Guideline:
Suggested in the following applications:
Coastal installations.
Windy areas or where debris is normally circulating.
Rooftop installations.
For improved sound ratings.
12. Thermostatic Expansion Valve (TXV)
A modulating flow--control valve which meters refrigerant liquid
flow rate into the evaporator in response to the superheat of the
refrigerant gas leaving the evaporator.
Kit includes valve, adapter tubes, and external equalizer tube. Hard
shut off types are available.
NOTE: When using a hard shut off TXV with single phase
reciprocating compressors, a Compressor Start Assist Capacitor
and Relay is required.
Usage Guideline:
Required to achieve ARI ratings in certain equipment
combinations. Refer to combination ratings.
Hard shut off TXV or LLS required in air conditioner
long line applications.

NOTES:
1. Ratings are net values reflecting the effects of circulating fan motor heat. Supplemental electric heat is not included.
2. Tested outdoor/indoor combinations have been tested in accordance with DOE test procedures for central air conditioners. Ratings for other combinations
are determined under DOE computer simulation procedures.
3. Determine actual CFM values obtainable for your system by referring to fan performance data in fan coil or furnace coil literature.
4. Minimum outdoor operating ambient in cooling mode is 55_F (12.8_C), maximum 115_F (46.1_C).

{ Total and sensible capacities are net capacities. Blower motor heat has been subtracted.
} Sensible capacities shown are based on 80° F (27° C) entering air at the indoor coil. For sensible capacities at other than 80° F (27° C), deduct 835 Btuh (245 kW) per 1000 CFM (480 L/S) of indoor coil air for each degree below
80° F (27° C), or add 835 Btuh (245 kW) per 1000 CFM (480 L/S) of indoor coil air per degree above 80° F (27° C).
When the required data falls between the published data, interpolation may be performed.
# Detailed cooling capacities are based on indoor and outdoor unit at the same elevation, per ARI Standard 210/240 ---94, and connected by 25 ft of tubing. If other than 25 ft of tubing is used and/or indoor unit is located above
outdoor unit, a slight variation in capacity may occur.
** Unit kW is total of indoor and outdoor unit kilowatts.

Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01--in. wc.
Minimum outdoor operating air temperature without low--ambient operation accessory is 55_F (12.8_C).
Maximum outdoor operating air temperature is 115_F (46.1_C).
For reliable operation, unit should be level in all horizontal planes.
Maximum elevation of indoor coil above or below base of outdoor unit is: indoor coil above = 80 ft (24.38 m), indoor coil below = 200
ft (60.96 m).
For interconnecting refrigerant tube lengths greater than 80 ft (24.38 m) horizontal or 20 ft (6.10 m) vertical differential, consult
Residential Split System Long--Line Application Guideline available from equipment distributor.
Crankcase heater required when interconnecting refrigerant tube length exceeds 80 ft (24.38 m).
If any refrigerant tubing is buried, provide a minimum 6 in (152.4 mm). vertical rise to the valve connections at the unit. Refrigerant
tubing lengths up to 36 in (914.4 mm). may be buried without further consideration.
Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
