SPLIT SYSTEM OUTDOOR UNIT © 2010-2011 Goodman Manufacturing Company, L.P. CKL , CKF, KFC SERIES INSTALLATION 8 OPERATING INSTRUCTIONS 5151 San Felipe, Suite 500, Houston, TX 77058 www.goodmanmifg.com -or Pin: 10-382C Date: September 2011 IMPORTANT SAFETY INSTRUCTIONS The following symbols and labels are used throughout this manual to indicate immediate or potential safety hazards.
. CRANKCASE HEATER Scroll equipped units do not have and do not require a crankcase heater, 3. TIME DELAY COMPONENT The time delay is located in the low voltage control circuit. When the compressor shuts off due to thermostat operation or a power failure, this components keeps the compressor off for at least 30 seconds which allows the system pressure to equalize. 4.
Heat pumps require special location consideration in areas of heavy snow congratulation and/or areas with prolonged continuous subfreezing temperatures. Heat pump unit bases are cutout under the outdoor coil to permit drainage of frost accumulation. Units must be situated to permit free unobstructed drainage of the defrost water and ice. A minimum 7.8 cm clearance under the outdoor coll is required in the milder climates.
NOTE: Be careful not to kink or dent refrigerant lines. Kinked or dented lines will cause poor performance or Compressor damage. Do NOT make final refrigerant line connection until plugs are removed from refrigerant tubing. 1. The ends of the refrigerant lines must be cut square, debarred, cleaned, and be round and free from nicks or dents. Any other condition increases the chance of a refrigerant leak. 2.

Purge gauge lines after attaching to the service valves, 2. Determine the proper charge from the serial data plate. Charge includes the evaporator ool and 7.6 m of line set. Systems having mare than 7.

NOTE When installing systems were the indoor outdoor sections are separated by more than 7.6 meters, note the maximum elevation separation limitations per the diagram in the LOCATION section of these instructions. 4. Determine the systems super heat as follows: a. Read the system's suction pressure, then using Table Hi determine the system's saturated suction tempera true. b. Read the suction line temperature. c. The system's super heat = the suction fine tempera true the saturated liquid temperature.
6. Remove the service gauge sets lines carefully Escaping liquid refrigerant can cause bums. 4) caution To prevent personal injury, carefully connect and disconnect manifold gauge hoses. Escaping liquid refrigerant can cause bums. Do not vent refrigerant into the atmosphere.
5. Defrost Control The defrost control provides time/ temperature initiation and termination of the defrost cycle. 8. Loss Of Charge Protector The control opens from its normally closed position to open the compressor contractor should the system lose its refrigerant charge. 7. Outdoor Thermostats These optional controls are used to prevent full electric heater operation at varying outdoor ambient (17.

D. Poor Terminating” Defrost Thermostat contact. Defrost thermostat must make good thermal contact on return bend, otherwise it may not terminate the defrost cycle quickly enough fo prevent unit from cutting out on high discharge pressure during the defrost cycle. E. Malfunctioning Reversing Valve: This may be due fo: 1. Solenoid not energized. In order to determine if the solenoid is energized, touch the nut that holds the solenoid cover in place with a screwdriver.
