__ Conrmthatmotordisconnectisopen
__ Isolate suction pressure transducer
__ Pressure test and leak check unit
__ Evacuate unit
__ Remove compressor drive coupling guard
__ Remove coupling center and DO NOT reinstall
(motor rotation must be checked without center)
__ Check for correct position of all hand, stop, and check
valves PRIOR to charging unit with OIL or REFRIGERANT
__ Charge unit with correct type and quantity of oil
__ Lubricate electric drive motor bearings PRIOR to
checking motor rotation
__ Check oil pump alignment (if applicable)
__ Check for correct economizer piping (if applicable)
__ Check separate source of liquid refrigerant supply (if
applicable, liquid injection oil cooling)
__ Check water supply for water-cooled oil cooler (if ap-
plicable, water cooled oil cooling)
__ Check thermosyphon receiver refrigerant level (if ap-
plicable, thermosyphon oil cooling)
__ Check for PROPER PIPE SUPPORTS and correct foundation
__ Check to ensure ALL piping INCLUDING RELIEF VALVES
is completed
After the above items have been checked and veried:
__ Close the main disconnect from the main power supply to the motor starter
__ Close the motor starter disconnect to energize the micro
__ Manually energize oil pump and check oil pump motor rotation
__ Leave micro energized to ensure oil heaters are on and oil temperature is correct for start-up
__ DO NOT energize compressor drive motor! Only authorized Factory Field Service Technicians are to perform this.
Summary: Ensure the above items are completed for when the FRICK Field Service Supervisor arrives . Ensure there is an
uncoupled compressor drive unit (to verify motor rotation and alignment) and energized oil heaters with the oil at the
proper standby temperatures . Full compliance with the above items contributes to a quick, efcient, and smooth start-up.
