Product Data 38YCB 50 Hz Heat Pump ® 38YCB Sizes 024 thru 060 Quality Assurance The 38YCB 50 Hertz Outdoor Sections of Split-System Heat Pumps are designed for quiet, reliable heating during the winter and cooling during the summer. With a SEER up to 10.0 and COP up to 3.0, these heat pump systems provide economy of operation through energy conservation when used with components designated by manufacturer. They recover heat for indoor comfort from outdoor air during the heating season and, by automatically reversing the refrigerant system, remove indoor heat and excess humidity during the cooling season. FEATURES/BENEFITS Electrical Range — Units are offered in single phase 220–240v. Threephase units are available in sizes 036, 048, and 060 in 400v. Size Range — The 38YCB is available in nominal sizes 024, 036, 048 and 060 to meet the needs for residential and light commercial applications. Compressor — Designed specifically for heat pump duty, with energy efficiency during heating and cooling operation. Each compressor is hermetically sealed against contamination to assure long life and dependable performance, internally sprung (units with reciprocating compressor) and externally mounted on rubber isolators for quiet operation. Continuous compressor operation is approved down to –30°F (–34.4°C) in the heating mode, and down to 55°F (12.8°C) in the cooling mode.

Built-in-Reliability Components — Includes a suctiontube accumulator that reduces the amount of liquid refrigerant that reaches the compressor; a lowpressure switch to stop the compressor if refrigerant charge is lost; a crankcase heater on units with reciprocating compressor and all 3-phase units to keep compressor oil warm and free of refrigerant for maximum lubricity; an internal compressor relief valve for high-pressure protection. Discharge Muffler — Minimizes low frequency sound and pressure pulsation generated by compressor discharge gas. Defrost Control Board — Incorporates a defrost relay, defrost timer, and low-voltage terminations. The defrost control is a time and temperature initiation/termination control which includes 3 fieldselectable time periods of 30, 50, and 90 minutes. The control includes builtin 5-minute compressor delay for units equipped with scroll compressors (see Compressor data table). Weather-Protective Cabinet — Steel is protected with a heavy coating commonly called “galvanizing,” and treated with a layer of zinc phosphate. A coat of 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. Unit Design — All units are equipped with totally enclosed fan motors for greater reliability under rain and snow conditions. The large, wraparound coil uses copper tube and enhanced aluminum fin and is designed for optimum heat transfer during heating and cooling. The vertical air discharge carries the sound and air up and away from adjacent patio areas and foliage. Coils can be cleaned with a common garden hose. External Service Valves — Both service valves are brass, front seating type. 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. The 38YCB has sweat field connections. Safety — All units are designed and manufactured in accordance with Underwriters Laboratories (U.L. 1995) standard for safety, heating and cooling equipment.

Time-Delay Relay A 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.) 2. Evaporator Freeze Thermostat A SPST temperature actuated switch which stops unit operation when evaporator reaches freeze-up conditions. SUGGESTED USE:All units where low-ambient controller has been added. 3. Isolation Relay A SPDT relay which switches the low-ambient controller out of the outdoor fan motor circuit when the heat pump switches to heating mode. SUGGESTED USE:All heat pumps where low-ambient controller has been added. 4. 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). Installations where outdoor design temperature exceeds 105°F (40.6°C). Replacement installations with hard shut-off expansion valve or liquid line solenoid on indoor coil. Units installed with low-ambient controller. 5. Sound Blanket Wraparound sound attenuation cover for the compressor. Reduces the sound level by about 0.2 bels. SUGGESTED USE:Unit installed closer than 15 ft (4.55m) to quiet areas—bedrooms, etc. Unit installed between 2 houses less than 10 ft (3.04m) apart. 6. Outdoor Thermostat A SPDT temperature actuated switch which turns on supplemental electric heaters when outdoor air temperature drops below set point. SUGGESTED USE:Heat pump installations with multiple-stage supplemental heaters 7. Secondary Outdoor Thermostat A SPDT temperature actuated switch which turns on a third stage of supplemental electric heaters when outdoor air temperature drops below the second-stage set point. SUGGESTED USE:Heat pump installations where 3-stage operation of supplemental heaters is desired. 8. Interface Control (Optimizer II) An electric control for controlling a heat pump and gas or oil furnace system for maximum energy savings. It allows heat pump to operate down to a predetermined economic balance point temperature, then switches to allow furnace operation only below that temperature. Requires outdoor thermostat to be adjusted for economic balance point temperature. SUGGESTED USE:All heat pump and gas- or oil-fired furnace combination systems. 9. 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 shut-off and RPB valves are available. SUGGESTED USE:For improved system performance in cooling mode. 10. 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 about 425 psig. Provides additional protection against compressor damage due to loss of outdoor airflow. SUGGESTED USE:Installations exposed to very “dirty” outdoor air. Installations where condenser inlet air temperature exceeds 125°F (51.7°C). 11. Filter Drier—Bi-flow A device for removing contaminants from refrigerant circulating in an air conditioner or heat pump system; bi-flow for heat pumps. SUGGESTED USE:All field-connected split-system units. 12. Liquid Solenoid Valve (LSV) An electrically operated shut-off valve to be installed at the outdoor unit and 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 (Item 4) must be used on single-phase reciprocating compressors. SUGGESTED USE:In certain long-line applications.

Outdoor fan external static pressure available is less than 0.01-in. wg. Minimum outdoor operating air temperature for cooling mode without low-ambient operation accessory is 55°F (12.8°C). Maximum outdoor operating air temperature for cooling mode is 125°F (51.7°C), except for some 3 phase models it is 115°F (46.7°C). Minimum outdoor operating air temperature for heating mode is –30°F (–34.4°C). Maximum outdoor operating air temperature for heating mode is 66°F (18.9°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 = 50 ft (15.24m), indoor coil below = 150 ft (45.72m). (See items 8 and 9 following.) For interconnecting refrigerant tube lengths greater than 50 ft (15.24m), consult Long-Line Application Guideline available from equipment distributor. Not more than 36 in. (912mm) of refrigerant tube should be buried in the ground. If necessary to bury tubes under a sidewalk, provide a minimum 6-in. (152mm) vertical rise to the valve connections at the unit. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided. Mixmatches of indoor coil capacity more than 1 size larger than outdoor unit capacity may result in inadequate indoor comfort.
