5.6 Exhaust filters replacement
Oil mist escaping form the exhaust during operation indicates that the filter is
probably choked up. Increased motor current could also be the result of a dirty
exhaust filter. Open the exhaust hood, take out the filter and replace it.
Also check the gasket of the exhaust flange and change it if necessary.
5.7 Gas ballast cleaning
If the filter of the gas ballast is dirty, the gas ballast is no longer operative. The
filter has to be replaced (see spare parts list).
5.8 Inlet flange sifter cleaning
To clean the inlet flange sifter, disconnect the inlet flange and clean the sifter with
blast air or an appropriate solvent.
5.9 Anti-suck back valve checking
The anti-suck back valve should be checked at the same time as the inlet flange
screen and if dirty, be cleaned with an appropriate solvent. Also check, if there is
no damage on the sealing part of the valve.
5.10 Fan cover cleaning
Dirt blockage of the fan cover may lead to over heating of the motor and the
pump. Put off the cover and clean it with blast air. Before starting the pump again,
be sure that the cover has been reassembled.
5.11 Checking the oil recovery system
When replacing the exhaust filter, check the cleanliness and the proper operation
of the float valve.
After having disassembled the exhaust flange, unscrew the oil recovery screw and
push the float valve by using its metallic part inside the oil casing, clean the nozzle
and check that the float itself oscillates free around its axle and that the valve is
tight.
Clean the float chamber of the oil casing. Reassemble in the reverse sequence.
