Frick Rotary Screw Compressor RWF II 209 SS

Reduce the system pressure to the desired condition.

Press [STOP] key to cease operation of the compressor.

Open disconnect switches for compressor motor and oil pump starters.

Turn on oil heater circuit breaker.

Close suction and discharge service valves, also liquid injection and economizer service valves, if applicable. Attach CLOSED TAGS.

Shut off cooling water supply valve to oil cooler, if applicable. Attach CLOSED TAG.

Protect oil cooler from ambient temperatures below freezing or remove water heads.

Warning: Always take vibration readings from exactly the same places and at exactly the same percentage of load.

Use vibration readings taken from the new unit at start-up as the base line reference.

Evaluate vibration readings carefully as the instrument range and function used can vary. Findings can be easily misinterpreted.

Vibration readings can be influenced by other equipment operating in the vicinity or connected to the same piping as the unit.

Is the Frick PhD on-board vibration monitoring system utilized?

If the Frick PhD has an alarm or shut down event, a full spectrum vibration analysis would then be required to specifically identify the cause of the alarm or shut down.

Is the Frick compressor package without PhD monitoring already in operation?

If yes, it can be retrofitted with the Frick PhD on-board vibration monitoring system to fulfill the vibration maintenance recommendation.

However, it is also necessary to establish a current baseline vibration with a full spectrum analysis in order for the PhD retrofit to be compliant.

Warning: This check requires trained personnel with PPE!

Check coupling: Check bolts, shim packs, center inserts, keys, and all bolt torques.

Check alignment: Refer to 070.210-IB for foot mounting alignment.

Suction and discharge flange bolts: Verify tightness of bolts on suction and discharge flanges. See Table 13 for torque requirements.

Check electrical connections: Check and torque all terminals in the processor and starter panel per the specification posted in the enclosure.

Check sensor calibration: Check calibration of slide valve, slide stop, pressures and temperatures. Calibration should be conducted with NIST certified devices.

WARNING: Do not mix oils of different brands, manufacturers, or types. Mixing of oils may cause excessive oil foaming, nuisance oil level cutouts, oil pressure loss, gas or oil leakage and catastrophic compressor failure.

NOTICE: The Frick oil charge shipped with the unit is the best suited lubricant for the conditions specified at the time of purchase. If there is any doubt due to the refrigerant, operating pressures, or temperatures, refer to Frick Oil publication 160.802-SPC for guidance. Only use Frick oil filter elements or warranty claim may be denied.

Participate in a regular, periodic oil analysis program to maintain oil and system integrity. Oil analysis kit part number: 333Q0001853.

Oil samples for analysis should be taken after the oil filter. A 1/4 in. purge valve is provided in the oil filter canister head.

WARNING: Exercise extreme caution in the vicinity of operating equipment. Skin contact with lube oil or inhalation of vapors can cause serious injury or death, consider gloves and eye protection.

Sample hot, active fluid while the equipment is operating. Sample after 30 min of compressor operation.

Unthread the oil sampling valve cap and locknut.

Shut down the compressor and allow pressures to equalize.

Isolate suction transducer PE-4 from the unit and depressurize.

Voltage across the red and black wires (power and DC common) of the transducer

Measure the voltage of PE-4 on connector P6A (terminals WHT and BLK) on the Analog Board with a digital voltmeter.

Isolate the oil pressure transducer PE-1 from the package and open it to atmosphere.

Measure the voltage of PE-1 on connector P5A (terminals WHT and BLK) on the Analog Board.

Isolate transducer PE-2 from the package and depressurize.
