Data
38CKC
60 Hz Air Conditioner
Sizes 018 thru 060
Model 38CKC Energy-Efficient Air
Conditioner incorporates innovative
technology to provide reliable summer
cooling performance. Built into these
units are the features most desired by
homeowners today, including SEER
ratings of up to 11.5 when used
with components designated by
manufacturer.All models are listed
with UL, c-UL, ARI, CEC, and
CSA-EEV.
AVAILABLE OPTIONS
Electrical Range — All units are
offered in 208–230v single phase.
Three-phase units are available from
030 through 060 sizes in 208/230v and
from 036 through 060 sizes in 460v.
Wide Range of Sizes — The 38CKC
is available in 7 nominal sizes from
018 through 060 to meet the needs of
residential and light commercial
applications.
WeatherArmor II Cabinet — The
steel is protected with a galvanized
coating and treated with a layer of zinc
phosphate. A modified polyester
powder coating is then applied and
baked on, providing each unit with a
hard, smooth finish that will last for
many years.
All screws on cabinet exterior are
coatedforalong-lasting,rust-resistant,
quality appearance.
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.

UnitDesign —Coppertube,enhanced
sine wave aluminum fin coil is
designed for optimum heat transfer.
Verticalairdischargecarriessoundand
hot condenser air up and away from
adjacent patio areas and foliage. Heat
pump style drain pan allows for easy
removal of water, dirt, and leaves.
Application Versatility — The unit
canbe combined with awide varietyof
evaporator coils and blower packages
to provide quiet, dependable comfort.
Unit can be installed on a roof or at
ground level.
External Service Valves — Service
valves are brass, front seating type. The
38CKC has sweat field connections.
Valves are externally located so
refrigeranttubeconnectionscanbemade
quickly and easily. Each valve has a
service port for ease of checking
operating refrigerant pressures.
Easy Serviceability — One access
panel provides access to electrical
controls and compressor. Removal of
wire dome gives access to fan motor
and removal of the top gives access to
the coil.
Compressor Protection — Each
compressor is protected with internal
temperature- and current-sensitive
overloads.
LimitedWarranty — Standard 1-year
warranty on parts, with an additional
4-year warranty on compressor.

SUGGESTED USE: Installations where interconnecting tube length exceeds 50 ft.
Installations where outdoor design temperature exceeds 105°F (40.6°C).
Replacement installations with hard shutoff expansion valve on indoor coil.
Installations where Liquid-Line Solenoid Valve has been added.
4. Compressor Start Assist — PTC
Solid-state electrical device which gives a ‘‘soft’’boost to the compressor at each start-up.
SUGGESTED USE: Installations with marginal power supply.
Replacement installations with rapid pressure balance (RPB) expansion valve on indoor coil.
5. 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 chance of refrigerant slugging. May or may not include a thermostat control.
SUGGESTED USE: When interconnecting tube length exceeds 50 ft.
When unit will be operated below 55°F (12.8°C) outdoor air temperature. (Use with low-ambient controller.)
All commercial installations.
6. Cycle Protector
Solid-state timing device which prevents compressor rapid recycling. Control provides an approximate 5-minute delay after power to the compressor has been
interrupted for any reason, including normal room thermostat cycling.
SUGGESTED USE: Installations in areas where power interruptions are frequent.
Where user is likely to ‘‘play’’ with the room thermostat.
All commercial installations.
Installations where interconnecting tube length exceeds 50 ft.
High-rise applications.

Accessory description and usage continued
7. Evaporator FreezeThermostat
An SPST temperature actuated switch which stops unit operation when evaporator reaches freeze-up conditions.
SUGGESTED USE: All units where Winter Start Control has been added.
8. Filter Drier
A device for removing contaminants from refrigerant circulating in an air conditioner: 1-direction flow.
SUGGESTED USE: All split-system air conditioners.
9. High-Pressure Switch
Auto reset SPST switch activated by refrigerant pressure on high side of refrigerant circuit. Cycles compressor off if refrigerant pressure rises to 400 ± 10 psig
and resets at 298 ± 20 psig. Provides protection against compressor damage due to loss of outdoor airflow. To prevent rapid compressor recycling, Cycle
Protector can be used with this switch.
SUGGESTED USE: Installations exposed to very ‘‘dirty’’ outdoor air.
Installations where condenser inlet air temperature exceeds 125°F (51.7°C).
10. Inlet Grille Kit
A field-installed enhanced inlet grille to replace the standard inlet grille on residential air conditioners and heat pumps.
SUGGESTED USE: For greater protection against inclement weather, incidental damage, and vandalism.
11. Liquid-Line Solenoid Valve (LSV)
An electrically operated shutoff valve to be installed at the outdoor or indoor unit (depending on tubing configuration) which stops and starts refrigerant liquid
flow in response to compressor operation. Maintains a column of refrigerant liquid ready for action at next compressor operation cycle.
NOTE: Compressor Start Assist–Capacitor and Relay must also be used. Do not use with hard shutoff TXV.
SUGGESTED USE: For improved system performance in air conditioners for certain combinations of indoor and outdoor units. Refer to ARI Unitary Directory.
In certain long-line applications. Refer to Long-Line Application Guideline.
12. Low-Ambient Controller
Head pressure controller is a cycle control device activated by a temperature sensor mounted on a header tube of the outdoor coil. It is designed to cycle the
outdoor fan motor in order to maintain condensing temperature within normal operating limits (approximately 100°F high and 60°F low).
The control will maintain working head pressure at low-ambient temperatures down to 0°F when properly installed.
SUGGESTED USE: Cooling operation at outdoor temperatures below 55°F (12.8°C).
13. Low-Pressure Switch
Auto reset SPST switch activated by refrigerant pressure on low side of refrigerant circuit. Cycles compressor off if refrigerant pressure drops to about 27
psig. Prevents indoor coil freeze-up due to loss of indoor airflow. Provides additional protection against compressor damage due to loss of refrigerant charge.
To prevent rapid compressor recycling, Cycle Protector can be used with this switch.
SUGGESTED USE: Where indoor coil is exposed to ‘‘dirty’’ air.
All commercial installations.
14. MotorMaster® Control
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, it maintains condensing temperature at 100°F ± 10°F.
SUGGESTED USE: Cooling operation at outdoor temperatures below 55°F.
All commercial installations.
15. Outdoor AirTemperature Sensor
A device that allows the temperature at a remote location (outdoors) to be displayed at the thermostat.
SUGGESTED USE: All corporate programmable thermostats.
16. Sound Hood
Wraparound sound attenuation cover for the compressor. Reduces unit sound level by about 2 dBA.
SUGGESTED USE: Unit installed closer than 15 ft to quiet areas — bedrooms, etc.
Unit installed between 2 houses less than 10 ft apart.
17. 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. Both hard shutoff and RPB valves are available. Do not use hard shutoff TXV with
Liquid-Line Solenoid Valve.
SUGGESTED USE: For improved system performance in cooling mode for certain combinations of indoor and outdoor units. Refer to ARI Unitary Directory.
Required for use on all zoning systems.
18. Time-Delay Relay
An SPST delay relay which briefly continues operation of the indoor blower motor to provide additional cooling after the compressor cycles off.
SUGGESTED USE: For improved efficiency ratings for certain combinations of indoor and outdoor units. Refer toARI Unitary Directory.
19. Winter Start Control
An SPST delay relay which bypasses the low-pressure switch for approximately 3 minutes to permit start-up for cooling operation under low-load conditions.
SUGGESTED USE: All air conditioners where Low-Ambient Controller has been added.
