Frick Rotary Screw Compressor RWF II 100

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.

When changing the coalescer filter element(s) it is recommended that the oil be changed, cartridge(s) in oil filters OF-1 and OF-2 if applicable be changed and the following applicable strainer elements be removed and cleaned.

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

1. See Changing oil, Steps 1 through 8.

2. Loosen manway cover retainer bolts, remove retainers, manway cover and cover gasket. Discard cover gasket.

3. Remove and retain nut securing coalescer filter retainer.

4. Remove retainer, coalescer filter element and 2 O-rings. Discard filter elements.' 5. Install new coalescer filter element(s).

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: This procedure requires trained personnel with PPE!

The Oil Level Transmitter is located on the front of the separator near the bottom/center.

The linear transmitter with hermetic enclosure is based on the capacitive measuring principle.

It features removable electronics (from the sensor well) eliminating the need to evacuate the compressor for replacement. This transmitter is dedicated to oil level control and has no user adjustments.

Remove DIN connector plug from transmitter.
