2.6.3 Cleaning the insert for the water
separator with filter
1. Depressurise the vessel of the water sep-
arator with filter.
2. Hold a suitable vessel under the conden-
sate drain. Drain the condensate.
3. Remove the vessel from the water sep-
arator with filter. Unscrew the mounting
screw from the filter insert anticlockwise
(fig. 4a).
4. Remove the filter insert and clean it in
soapy water (max. 50 °C).
5. To refit the filter insert, reverse the pro-
cedure used to remove it.
2.6.4 Draining the condensate from
the water separator with filter
Draining semi-automatically: Rotate the
condensate drain valve 1/4 turn anticlock-
wise. Under 1 bar: condensate drains. (Fig-
ure 4a)
Draining manually: Rotate the condensate
drain valve clockwise and push it up. Con-
densate drains.
2.6.5 Draining condensate from pres-
sure vessel
 Dispose of condensate in accordance with
local specifications!
Caution: Wear safety glasses!
1. Place a suitable vessel under the conden-
sate drain.
2. In order to drain condensate, the vessel
pressure must be 2 - 3 bar.
3. Open condensate drain valve (item 09).
4. Close condensate drain valve again fol-
lowing condensate drainage.
2.6.6 Checking the oil level
• The oil level must be between the top and
bottom marks (oil dipstick/oil inspection
glass) (Figure 7a).
• Correct if necessary.
 If oil is milky, it must be changed immedi-
ately.
2.6.7 Changing/adding oil
1. Allow the compressor to warm up, switch
it off, disconnect the power supply.
2. Pull out the oil filler plug/oil dipstick
(item 03), hold the used oil container un-
der the oil filler plug (item 04), screw
open the oil drain screw, drain used oil
completely.

3. Screw the oil drain screw closed.
4. Add the prescribed quantity of oil.
5. Check the oil level, correct if necessary.
Insert the oil filler plug or oil dipstick.
6. Dispose of used oil according to applica-
ble regulations.
 Recommendation: mineral oil Art. No.
B111002, synthetic oil Art. No. B111006.
No guarantee can be provided if the
wrong oils are used.
Do not mix synthetic and mineral oil:
compressor damage is possible!
2.6.8 Checking the screw fittings
• Check that all the screw connections are
secure, and retighten them if necessary.
2.6.9 Cleaning the intake filter
See instruction manual, part 1.
 Do not purge the intake opening. No for-
eign objects may enter.
Never operate the compressor without an
intake filter.
2.6.10 Cleaning/replacing the check
valve
1. Unscrew the locking screw (Figure 6a).
2. Clean insert, replace in case of damage,
squeezing or hardening.
3. Clean seat, replace complete check valve
if damaged.
2.6.11 Replacing the safety valve
1. Unscrew the safety valve (item 11) anti-
clockwise.
2. Apply medium-strength thread-locking
fluid, e.g. Loctite® 243, to the thread of
the new safety valve or wrap Teflon tape
around the valve.
3. Tightly screw the new safety valve in
clockwise.
2.6.12 Water separator with filter
Changing the filter element
1. Remove the filter housing.
2. Unscrew the filter element (fig. 4a) and
fit the new filter element.
3. To fit the new filter element, reverse the
procedure used to remove the old one.
2.7 Decommissioning
2.7.1 Preservation
Oil-lubricated compressors: compressor is
taken out of service for a long period (over 6
months) or is new from the factory and will
not be operated until much later.
