– The fan cover should also be checked regularly for dirt. Spoiling the
fan cover prevents cool air intake and may lead to overheating of the
vacuum pump.
Cleaning oil reservoir
– The oil reservoir should be disassembled and cleaned at least every
6 months. When the vacuumfilling installation is used intensively,
the reservoir has to be cleaned more often. During filling of dampers
a small amount of assembling dirt of the damper is coming into the
oil reservoir. The dirt sinks down in the reservoir and gets caught
behind a ridge in the reservoir. This prevents the dirt from
(re)entering the damper. When too much dirt is collected, the dirt
will be able to enter the damper. For this reason regular cleaning is
necessary.
– For draining the oil reservoir, connect filling adaptor A to the damper
connector of the filling unit and place the adaptor above a
measuring cup. Let the oil run out of the reservoir. When there is no
more oil flowing, the filling adaptor can be disconnected.
– Clean seperators before taking out oil reservoir, according to
description under “frequent checks”.
– Remove the pressure pipe from the pressure regulator.
– Remove the vacuum pipe from the oil seperator.
– Remove the 4 bolts of the oil reservoir, while supporting the
reservoir to prevent it from falling.
– When the bolts have been removed, gently move the backside of the
reservoir inwards. This way the oil level indicator will not get stuck
behind the backplate of the installation.
