8.8 USING THE COMPRESSOR WITH SYNTHETIC OILS
If you wish to use a synthetic lubricant, carefully follow the procedure below.
 Drain all mineral oil from the compressor circuit using the oil drain ball valve.
 Feed the synthetic lubricant or detergent oil into the oil tank through the top-up hole and
fill up to the correct level.
 Before starting up the compressor or the first time after installation, feed approximately
0.1 l of lubricant in through the regulator intake opening while keeping the suction valve
shutter lowered and manually turning the screw rotors in the right direction.
CAUTION!
When lowering the suction valve shutter be careful not to damage the throttle valve O-
ring.
 Start up the compressor, initially switching it on and off sequentially and quickly and
then starting it up.
 Then turn off the compressor and drain all lubricant from the system using the ball
valve.
 Through the oil top-up hole, feed new synthetic lubricant in until it reaches the set level;
then start up the compressor and run it steady for about 10 minutes.
 Turn off the compressor, vent the pressure and, if necessary, top up by feeding the
lubricant through the top-up hole until the right level is read on the window.
CAUTION!
If the above-mentioned “washing” cycle is not performed, the mixing of incompatible
lubricants may cause problems in lubrication. Use adequate protection when handling
lubricants.
Dispose of mineral lubricants in compliance with current environmental regulations.
CAUTION!
Before performing any operation involving draining or topping up compressor oil,
unplug the compressor and wait until the system has reached atmospheric pressure.
Use adequate protection when handling lubricants.
