Replacement of filter elements:
Depressurise the housing. Secure the shut-off valves so that they
cannot be accidentally opened. Check that the unit is unpressurized
by manually opening the condensate drain. Use only a suitable tool to
unscrew the bottom half of the filter.
Unscrew the bottom half of the housing anti-clockwise.
Take the element out of the filter bowl.
Take the new filter element from its cartonage, grease the O-ring (we
recommend food industry grease), and put the element in the filter
bowl. Please make sure that the three wings are positioned in the res-
pective spots inside the bowl. Check the O-ring in the filter housing and
apply grease here too if necessary. Also grease the thread of the lower
part of the filter.
Remove any dirt from the bottom half of the filter, and then rescrew it
clockwise to the filter head.
Reopen the compressed air supply slowly and check for leaks. In the
event of any leakage, immediately depressurize the system and fix the
leaks.
Replacement of condensate drain:
Due to adhesion and rust and dust particles, the condensate drain may
have to be regularly replaced. In this case, first proceed as described
above.
Turn the condensate drain clockwise at the flats (metric wrench size 15)
to remove it. Then screw in the new condensate drain counter-clockwise
in the same way.
Please note that the removed components, in particular filter elements, are
contaminated with compressor oils. These must be safely disposed in ac-
cordance with regional waste disposal guidelines and regulations for
materials contaminated with oil!
