Manual condensation dump system
Oil- / water separators
The unit comes as standard with a manual condensation
dump system. Drain condensate separators every 15 minutes.
To release the complete condensate through the black plastic
hoses we recommend using a 20 l container at least.
The drain noise can be kept to a minimum by using a
silencer.
Manual drain
To drain manually, open the condensate drain valves of the
2nd oil / water separator and the condensate drain valve of
the final filter housing (Fig. 2).
Open valve spindle max. 1.5 turns anti-clockwise. The
condensate will be drained.
Then close valve spindle clockwise.
Maintenance intervals
We recommend to clean oil and water separators every 500
operating hours or at least once a year, to check for corrosion
damage and to replace o-rings if necessary.
All oil / water separators have an integrated sinter filter which
has to be replaced every 1,000 operating hours.
Note
The collected condensate can contain oil and has
to be disposed according to regulations.
