Disconnecting the compressor
At the end of the service life of the compressor, proceed as follows:
Step Action
1 Stop the compressor and close the air outlet valve.
2 Switch off the voltage and disconnect the compressor from the mains.
3 Depressurize the compressor by opening the drain valve and loosening the oil filler plug
one turn.
4 Shut off and depressurize the part of the air net which is connected to the outlet valve.
Disconnect the compressor air outlet pipe from the air net.

Instructions
Step Action
1 This equipment can contain pressurised air and oil; be aware of its potential danger if used
improperly.
2 This equipment must only be used as compressed air/oil separator and must be operated
within the specified limits.
3 No alterations must be made to this equipment by welding, drilling, grinding or other
methods of mechanical working without written permission of the manufacturer. If there is
damage to a part under pressure from any cause, the complete part must be replaced.
4 For the oil separator vessel: original bolts have to be used after opening for inside
inspection. The bolts must be removed and fitted with the correct tool. The bolts must be
tightened with a torque of 355 Nm (+/- 85 Nm). Damaged bolts must not be re-used. O-
rings must be replaced.
5 The safety valve is designed in such a way that the pressure will not permanently exceed
the maximum allowable operating pressure of the vessel, except for short pressure surges
up to 1.1 times the design pressure.
6 Only use oil specified by the manufacturer.
7 Make sure the vessel is fully depressurised before opening the drain plug or fill plug.
