®
vertically.

return connectors and secure using hose
clamps.
To guarantee safe operation, the ProVent
®
should be protected from dirt (by fitting splash
guards).
5. Maintenance
Only carry out maintenance work when
the motor is switched off. Never start
without an oil separator and/or cover.
Danger of burns from hot air that may
escape. Housing, cover and hoses can
become very hot.
The maintenance of the ProVent
®
essentially
involves replacing the oil separator.
Check the ProVent
®
regularly for damage and
external soiling.
High-pressure cleaners may not be
used, as the valves may be damaged
and water may enter the oil circuit.
5.1. Maintenance intervals
The oil separator must be replaced in accor-
dance with specifications from the device
manufacturer or after 1000 operating hours
at the latest.
Maintenance intervals may need to be
shortened depending on the operating
conditions. In normal mode, if the O-
ring is intact and oil leaks through the
bypass valve (item 2, customer draw-
ing), this indicates that the oil sepa-
rator is worn and must be replaced
immediately.
5.2. Removing the oil separator
– Rotate the cover approx. half a turn anti-
clockwise and remove. Should the cover be
difficult to move, a tool (e.g. screwdriver)
can be used to help turn the cover (see
customer drawing).
– Pull the oil separator upwards to remove
and dispose of as per local waste regula-
tions.
5.3. Assembly
– Clean housing, cover and sealing sur-
faces.
– Change O-ring (item 2, customer drawing)
and rub in a small amount of engine oil.
– Slide the new oil separator into the housing
with a new, slightly oiled O-ring.
– Put on the cover and turn clockwise until it
latches into place.
