C. Exhaust filters replacement
See safety information page 3.
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.
D. Checking the oil recovery system
See safety information page 3.
During the exchange of the exhaust filter, check the cleanliness of the foam which
protects the oil return compartment and the oil recovery system. Disassemble the
oil return screw system from the end plate and check the cleanliness of the nozzle
(without disassembling it from the unit). In case of heavy dirtiness, replace the
whole oil recovery screw system.
E. Gas ballast cleaning
See safety information page 3.
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).
F. Inlet flange sifter cleaning
See safety information page 3.
To clean the inlet flange screen, disconnect the inlet flange and clean the screen
with blast air or an appropriate solvent.
G. Anti-suck back valve checking
See safety information page 3.
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.
H. Fan cover cleaning
Dirt blockage of the fan cover may lead to overheating 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.
