38CKX Sizes 024 thru 060
Model 38CKX 50 Hertz Energy­Efficient Air Conditioner incorporates innovative technology to provide reliable summer cooling performance. Built into these units are the features most desired by consumers today, including SEER ratings of up to 10.0 when used with components designated by manufacturer.
AVAILABLE OPTIONS
Electrical Range — Units are offered
in 230v single phase for 024 and 036 sizes. Three-phase units are available in 036, 048, and 060 sizes in 400v.
Wide Range of Sizes — The 38CKX
is available in nominal sizes 024, 036, 048, and 060 to meet the needs of residential and light commercial applications.
Weather Armor II Cabinet — The
steel is protected with a galvanize 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 coated for a long-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.

)
Unit Design — 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. Heat pump style drain pan allows for easy remov al of water, dirt, and lea v es.
Application Versatility — The unit
can be combined with a wide variety of evaporator coils and blower packages to provide quiet, dependable comfort.
Unit can be installed on a roof or at ground level.
External Service Valves — Both
service valves are brass, front seating type. The 38CKX has sweat field 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.
Easy Serviceability — One access
panel provides access to electrical

Accessory description and usage (Listed alphabetically)
1.
Coastal Filter
A mesh screen inserted under the top cover and inside the base pan to protect the condenser coil from salt damage without restricting airflow.
SUGGESTED USE: In geographic areas where salt damage could occur.
2.
Compressor Start Assist — Capacitor/Relay Type
Start capacitor and start relay gives ‘‘hard’’ boost to compressor motor at each start-up.
SUGGESTED USE: Installations where interconnecting tube length exceeds 50 ft (15.24m).
Compressor Start Assist — PTC Type
3.
Solid-state electrical device which gives a ‘‘soft’’ boost to the compressor at each start-up.
SUGGESTED USE: Installations with marginal power supply.
Crankcase Heater
4.
An electric resistance heater which mounts to the base of the compressor to keep the lubricant warm during off cycles. Improv es 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 (15.24m).
Cycle Protector
5.
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.
Evaporator Freeze Thermostat
6.
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.
7.
Liquid 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/relay type must also be used.
SUGGESTED USE: For improved system performance in air conditioners for certain combinations of indoor and outdoor units. (Refer to ARI
8.
Low-Ambient Controller
This solid-state head pressure controller is a cycle control device activated by a temperature sensor. It is specifically designed to control outdoor fan motor run time in response to saturated condensing temperature. For outdoor air temperatures between 55°F and 0°F (12.8°C and –17.8°C), it maintains condensing temperature at 75°F and 130°F (23.8°C and 54.4°C).
SUGGESTED USE: Cooling operation at outdoor temperatures below 55°F (12.8°C).
9.
Support Feet
Four stick-on plastic feet which raise the unit 4 in. above the mounting pad. This allows sand, dirt, and other debris to be flushed from the unit base; minimizes corrosion.
SUGGESTED USE: Coastal installations.
10.
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.
SUGGESTED USE: For improved system performance in cooling mode for certain combinations of indoor and outdoor units. (Refer to ARI
11.
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 to ARI Unitary Directory.)
Winter Start Control
12.
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.
Installations where outdoor design temperature exceeds 105°F (40.6°C). Replacement installations with hard shutoff expansion valve on indoor coil.
Replacement installations with rapid pressure balance (RPB) thermostatic expansion valve on indoor coil.
When unit will be operated below 55°F (12.8°C) outdoor air temperature. (Use with low-ambient controller.) All commercial installations.
Where user is likely to ‘‘play’’ with the room thermostat. All commercial installations. Installations where interconnecting tube length exceeds 50 ft (15.24m). High-rise applications.
Unitary Directory.) In certain long-line applications. (Refer to Long-Line Application Guideline).
Windy areas or where debris is normally cirdculating. Rooftop installations.
Unitary Directory. Required for use on all zoning systems.

* Detailed cooling capacities are based on indoor and outdoor unit at the same elevation per ARI standard 210/240-94. If additional tubing length
and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur. † Total and sensible capacities are net capacities. Blower motor heat has been subtracted. ‡ Sensible capacities shown are based on 27°C entering air at the indoor coil. For sensible capacities at other than 27°C, deduct 245 kw per 480
L/S of indoor coil air for each degree below 27°C, or add 245 kw per 480 L/S of indoor coil air per degree above 27°C.
When the required data falls between the published data, interpolation may be performed.
** Unit kw is total of indoor and outdoor unit kilowatts.

System Design
1. Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01-in. wg.
2. Minimum outdoor operating air temperature without low-ambient operation accessory is 55°F (12.8°C).
3. Maximum outdoor operating air temperature is 125°F (51.7°C).
4. For reliable operation, unit should be level in all horizontal planes.
5. Maximum elevation of indoor coil above or below base of outdoor unit is: indoor coil above = 50 ft (15.24m), indoor coil below = 150 ft
(45.72m).
6. For interconnecting refrigerant tube lengths greater than 50 ft (15.24m), consult Long-Line Application Guideline available from equipment
distributor.
7. Crankcase heater required when interconnecting refrigerant tube length exceeds 50 ft (15.24m).
8. If any refrigerant tubing is buried, provide a minimum 6 in. (152mm) vertical rise to the valve connections at the unit. Refrigerant tubing
lengths up to 36 in. (912mm) may be buried without further consideration. For buried lines longer than 3 ft (912mm), consult your local distributor.
9. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
