Warning
The pressure reservoir is under pressure!
Only replace the oil sine separator when the
screw compressor unit is out of operation,
depressurized, and secured from being
switched on again!
Be careful with hot oil: Danger of scalding!
Important
Do not spill oil!
Note
Dispose of the fine separator cartridge in line with the
regulations - special waste! Check for leakage!
For the changing intervals, see the maintenance
schedule.
If the oil fine separator is monitored (option), too high a
differential pressure is indicated on the keypad of the
compressor control DELCOS XL. When the
corresponding warning lights up, change the oil fine
separator.

Change the oil fine separator as follows:
Switch the screw compressor unit off and ensure
•
that it is depressurized, electrically isolate and
locked off. For this, while the system is switched off
carefully open the ballcock (- 1 - Fig. 22) on the
downstream cooler until the system has been bled,
then close the stopcock again.
Loosen the plastic tube (- 2 - Fig. 21) of the oil
•
extractor (- 4 - Fig. 21).
Loosen the plastic tube of the control air line
•
(- 3 - Fig. 21).
Fully remove oil extraction with pressed in extraction
•
tube (- 4 - Fig. 21).
Loosen all hexagonal head screws from the
•
pressure control valve.
Loosen the two screws in the swivel direction of the
•
pressure control valve and remove, then the valve
can be swivelled inwards.
Remove all hexagon screws (- 7 - Fig. 21) on the
•
circumference of the pressure reservoirʼs cover.
The cheese head screw for lifting the reservoir cover
•
(- 8 - Fig. 21) must be screwed in clockwise until the
cover is lifted off by some mm.
Swivel the reservoir cover by 180° (- 1 - Fig. 21).
•
Remove used oil fine separator (- 1 - Fig. 21).
•
Clean sealing faces and, if required, remove and
•
clean O-rings.
