READ THIS FIRST: COMPRESSOR PRESTART CHECKLIST
The following items MUST be checked and completed by the installer prior to the arrival of the Frick Field
Service Supervisor. Details on the checklist can be found in this manual. Certain items on this checklist will
be reverified by the Frick Field Service Supervisor prior to the actual start-up.
Mechanical Checks
__ Package installed according to Frick publication
S70-210 IB, Screw Compressor Foundations.
__ Confirm 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 verified:
__ 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 ! This should only be done by authorized Factory Field Service Technicians.
Summary: The Frick Field Service Supervisor should arrive to find the above items completed. He should find 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 will contribute to a quick, efficient and smooth start-up.
The Start-up Supervisor will:
1. Verify position of all valves
2. Verify all wiring connections
3. Verify compressor motor rotation
4. Verify oil pump motor rotation
5. Verify the % of FLA on the micro display
NOTE: Customer connections are to be made per the electrical diagram for the motor starter listed under the
installation section and per the wiring diagram listed under the maintenance section of the IOM.
Please complete and sign this form & fax to 717-762-8624 as confirmation of completion.
