Components for reducing noise on the pump-
motor unit:
Mufflers (included as standard equipment):
On delivery the pump-motor units are
equipped with attached mufflers as standard.
The noise radiation is considerably reduced
by the mufflers. See Fig. 2 to Fig. 4, Pg. 18 ff.
Additional mufflers (available as an option):
The additional mufflers enable a further noise
reduction. They may only be used with free
entry and exit of gases, i.e. with direct intake
out of or direct feeding into the atmosphere
without piping.
Noise protection hoods (available as an
option):
Noise protection hoods are suitable for
installation in rooms and in the open. They
reduce both the total sound pressure level
and tonal components that are perceived as
particularly annoying.
Installation variants/axis position:
Basically, when installing the pump-motor unit,
the following variants are possible with a different
axis position (horizontal or vertical):
Horizontal installation
Vertical installation on the vacuum
pump/compressor cover ("cover installation")
Vertical mounting on the wall.
Basically, all variants are possible with all
models.
However, a distinction must be made between a
design with and a design without a condensed
water opening for the axis position:
The pump-motor units without a condensed
water opening can be installed and secured in
any axis position.
The pump-motor unit with a condensed water
opening may only be installed and secured
horizontally with the base at the bottom.
Horizontal installation
Screw the base of the pump-motor unit to the
surface with suitable mounting elements.
Proceed as follows:
Provide the base of the pump-motor unit with
mounting holes.
Select the suitable screw type.
Screw the base of the pump-motor unit to the
surface with the screws.
When doing so, be sure to provide all
mounting holes with screws!

Vertical installation on the vacuum
pump/compressor cover ("cover installation")
With vertical installation of the pump-motor unit
with the vacuum pump/compressor cover facing
downward, rubber feet must be used.
Proceed as follows:
The rubber feet are available as accessories.
They are delivered in a set of 3.
On the upper section they are provided with
stud bolts and on the lower section with a
threaded hole.
Mount the rubber feet on the pump-motor unit:
Screw the stud bolts of the rubber feed into
the holes on the face of the vacuum
pump/compressor cover and tighten them.
Mount the pump-motor unit together with the
rubber feet on the installation surface:
Select suitable mounting elements for the
threaded hole.
Screw the rubber feet to the surface or
foundation via the threaded hole.
Vertical mounting on the wall
With vertical mounting of the pump-motor unit on
the wall, the pump-motor unit is mounted via the
holes in the base.
Proceed as follows:
Position the pump-motor unit as close to the
wall as possible on a stable supporting plate
with sufficient load-bearing capacity.
The pump-motor unit must be positioned with
the base toward the wall.
Provide the base of the pump-motor unit with
mounting holes.
Select the suitable screw type.
Screw the base of the pump-motor unit to the
wall with the screws.
When doing so, be sure to provide all
mounting holes with screws!
Remove the supporting plate.
Eye bolt:
Following installation, the eye bolt must be either
firmly tightened or removed.
