Frick Rotary Screw Compressor RWF II 316

WARNING: Failure to enter skip frequencies could cause catastrophic compressor failure or severe compressor damage and result in serious injury or death.

Check for excess vibration and skip frequencies anytime unit operating conditions change

Decrease the VFD speed by 100 rpm increments and check for elevated energy

Enter the vibration meter reading

Does the vibration meter reading meet or exceed one inch per second?

If the vibration meter reading meets or exceeds one inch per second, skip that frequency range in the microprocessor for the VFD

Enter the identified frequency range to be skipped

Set the skip to as narrow a frequency band as possible, only making it wider until full range is accommodated

To clean the demand oil pump strainer, the unit must be shut down. The procedure is as follows:

1. Push [STOP] key on microprocessor panel to shutdown unit, then open disconnect switches for compressor and oil pump motor starters.

2. Close strainer inlet service valve.

3. Open drain valve located in the strainer cover and drain oil into a container.

4. Remove capscrews securing strainer cover, strainer cover, gasket and element. Retain gasket.

5. Wash element in solvent and blow clean with air.

6. Wipe strainer body cavity clean with a lint-free clean cloth.

WARNING: Be extremely careful not to loosen thermowell while attempting to remove the temperature sensor. The use of two wrenches will be necessary to ensure the thermowell remains stationary. Loss of oil and/or refrigerant could occur. Exposure to refrigerant fumes and/or hot oil can cause injury or death.

NOTICE: The temperature sensor is factory set. If calibration is required, refer to Calibration Instructions in publication 090.040-O for service technicians.

Performing a few preventive maintenance procedures will extend the life of your pump and reduce the cost per gallon pumped.

1. Lubrication - Grease all zerks after every 500 hours of operation or after 60 days, whichever occurs first. If service is severe, grease more often.

Did you use a hand gun for greasing?

Warning: Use of filter elements other than Frick may cause warranty claim to be denied.

Is a single oil filter installed?

If a single oil filter is installed, push [STOP] key on microprocessor panel to shut down unit, then open disconnect switches for compressor and oil pump motor starters.

Are dual oil filters installed?

If dual oil filters are installed, open the outlet, then inlet service valves of the standby filter.

Warning: Open inlet service valve slowly to prevent a sudden pressure drop which could cause an oil filter differential alarm.

Close outlet then inlet service valves of filter being serviced.

Open bleed valve and purge pressure from the oil filter cartridge.

Remove the plug from the bottom of the filter canister and drain the oil. Remove the canister cover and discard the gasket. Remove the screws securing the filter assembly. Pull the filter assembly from the canister and discard the gasket and the element.
