Compressors with condensation and filtration unit. (Fig.11)
In the case of regular operation, condensate is automatically released via release valve of condensation unit
filter. Perform the control of the function of automatic sludging as follows: Open valve (4) of sludging vessel
(2) by unscrewing to left, release small amount of condensate from the vessel. Close valve (4) again by
screwing to right, thus automatic mode of sludging is adjusted.
Compressors with air dryer
In the case of regular operation, condensate is automatically released via air dryer.
For compressor version with case DK50 S, DK50-10 S, DK5010-S/M the case has to be
removed. Move the case up before the following inspections.
(for DK5010-S/M first disconnect valve for regeneration - fig.3)
15.2. Control of safety valve
(Fig.7)
At the compressor is put into operation for the first time, it is necessary to control correct function of safety
valve. Turn screw (4) of safety valve (1) several rotations to left till safety valve blows out. Let safety valve
blow out only for a short time period. Turn screw (1) to right till backstop, valve must be closed now again.
During this control, pressure tank must be under pressure of max. 6 bars.
Safety valve must not be used for depressurizing of pressure tank. It could endanger the
function of safety valve. It is adjusted to permitted maximal pressure by manufacturer, it is
tested and marked. It must not be readjusted.
Warning ! Compressed air may be dangerous. You may have to protect your sight when
blowing air out. Its impediment may occur.
15.3. Replacement of input filter

•
Remove the dryer plug (1) by unscrewing to the left on the body(4).
•
Change the filter (2).
•
Put a plug to the body (4) and tighten it to right.
15.5. Replacement of filter in condensation and filtration unit
Prior the intervention, it is necessary to reduce air pressure
in air chamber to zero and disconnect the appliance from
mains.
(Fig.11)
In the case of a regular operation of condensation unit, it is necessary to
replace filtration pad in filter with automatic sludge drain once a year.
•
Loosen fuse (1) at filter by pulling it down and turn the cover of filter (2) to
