Frick Rotary Screw Compressor RWF II 222

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.

This section provides instructions for normal maintenance, a recommended maintenance program, troubleshooting and correction guides, and typical P and I diagrams. For typical wiring diagrams and information about the Quantum™ HD control panel, refer to 090.040-M.

This section must be read and understood before attempting to perform any maintenance or service to the unit.

When performing maintenance you must take several precautions to ensure your safety:

1. If unit is running, press [stop] key.

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 a 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 procedure requires trained personnel with PPE!

EZ-CAL High pressure cut-out check valve test block

Is the EZ-CAL test block installed on the package?

Is the pressure transducer wired to the Quantum HD controller?

Is the tubing run to the compressor discharge connection?

Is the HPCO fully open to the discharge pressure source in the RUN position?

Is the external pressure source connected to the test connection quick connect in the TEST position?

Is the external source connected directly to the HPCO in the TEST position?

See Publication 070.660-SM for procedures covering replacement motor and compressor mounting.

Push [STOP] key on control panel to shut down unit.

Open disconnect switches for compressor and pump motor starters.

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

Slowly vent separator to low-side system pressure using the bypass line on the suction trap.

Recover or transfer all refrigerant vapor, in accordance with local ordinances, before opening to atmosphere. The separator must be equalized to atmospheric pressure.
