- the operating conditions change,
- conversions are carried out without
consultation with the manufacturer,
- necessary maintenance and repair work is
notperformed.

and in accordance with the respective
technical specifications, observing correct
procedures regarding safety and danger, and
incompliance with the operating instructions.
Rectify immediately (or have rectified) all
faults, especially if they affect safety.

necessary, specified safety equipment.
2.3 Operational safety
All modes of operation that may affect
operational safety of the ProVent must be
avoided.
Independent conversions or modifications to
the ProVent are not permitted under any
circumstances. Furthermore, the
manufacturer’s warranty would imme-
diately become invalid.

3. Description
TheProVent isa crankcaseventilationsystem
and essentially consists of a housing with an
integral pressure control valve, a cover with a
bypass valve, an oil separator and a support.
The ProVent can be used as an open system
(oil seperation only) or as a closed crankcase
ventilation system (recirculation of the blow-
by gases and regulation of the crankcase
pressure as well).
The environmental regulations of

4. Installation
The ProVent can be positioned in the support
at twelve increments of 30° and at four height
settings.

- Close fixing.
- Mount bracket fitted to the ProVent
vertically.
Tightening torque: 9 ± 2 Nm.
- Attach hose lines at inlet, outlet and oil
return connectors and secure using hose
clamps.
To guarantee safe operation, the ProVent
should beprotectedfromdirt(byfittingsplash
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
accordance 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
leaksthroughthebypassvalve(item
2,customer drawing),this indicates
that the oil separator is worn and
must be replaced immediately.
5.2. Removing the oil separator
- Rotate the cover approx. half a turn
anticlockwise 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
regulations.
5.3. Assembly
- Clean housing, cover and sealing surfaces.
- 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.
