Manual condensation dump system
The LW 450 E Compact III comes as standard with an manual
condensate drain. 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
1st, 2nd and 3rd stage of the oil / water separators and the
condensate drain valve of the filter housing (Fig. 2).
Open valve spindle max. 1.5 turns anti-clockwise. The conden-
sate 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.

Warning
Open valve spindle max. 1.5 turns.
The pressure in the housing can shoot out the
valve spindles at high speed.
