Procedure
- Check the oil level, top up if necessary. See section
- On water-cooled compressors, also:
• Check that the cooling water drain valves in the inlet and outlet pipes are closed.
• Open the cooling water inlet valve.
• Open the water flow regulating valve. This step can be skipped if, after previous operation, the
setting of this valve has not been changed.

Incorrect rotation of the drive motor can cause damage to the compressor.
• If the compressor has not run for the past 6 months, it is strongly recommended to
improve the lubrication of the compressor element at starting. Disconnect the inlet
hose, remove the unloader (UA) and pour 0.75 l (0.20 US gal, 0.17 Imp gal) of oil
into the compressor element. Reinstall the unloader and reconnect the inlet hose.
Make sure that all connections are tight.
• On compressors with dryer, switch on the voltage 4 hours before starting to
energise the crankcase heater of the refrigerant compressor of the dryer.
