The pump-motor unit is ready to connect on
delivery.
However, if the time from delivery to
commissioning of the pump-motor unit exceeds a
certain period, the lubrication of the rolling
bearings must be renewed.
See Chapter 8.2, "Storage conditions",
Section "Lubrication of rolling bearings after
longer storage", Pg. 23 for information on this
topic.
Carry out the following work to install the pump-
motor unit:
 Installation and securing,
 Attachment of the included loose muffler if
necessary,
 Attachment of threaded flange or hose flange
(available as accessories)
for the connection of inlet or discharge pipe to
the muffler,
 Electrical connection,
 Connection of inlet and discharge connection
to the system.
5.1 Installation
 WARNING
For an installation that differs from the following
specifications, it is necessary to inquire with the
Service Department!
Ambient conditions:
The pump-motor unit is suitable for installation in
the following environments:
 In a dusty or damp environment,
 in
buildings,
 in the open.
When properly installed in the open, the
pump-motor unit must be protected from
exposure to intensive sunlight, e.g. by
attaching a protective roof. Otherwise, no
special protective devices against the effects
of weathering are required.
NOTICE
The maximum permissible loading due to
vibrations may not be exceeded!
See Chapter 3.1, "Mechanical data",
Section "Vibrations", Pg. 8 for information on
this topic.
The drive motors of the pump-motor units have
the following design:
 with degree of protection IP55 (see rating
plate),
 with tropicalized insulation.
Installation conditions:
The pump-motor unit must be installed as
follows:
 on level surfaces,
 at a maximum height of 1000 m [3,280 ft]
above sea level.
When installing at an altitude of more than
1,000 m [3,280 ft]above sea level, first inquire
with the Service Department.
Minimum distance:
To ensure sufficient cooling of the pump-motor
unit, it is absolutely necessary that the required
minimum distances to the fan guard and to the
face of the vacuum pump/compressor cover
be maintained.
See Chapter 3.1, "Mechanical data",
Section "Minimum distances", Pg. 8.
The compliance of the specified minimum
distance to the face of the vacuum
pump/compressor cover is especially important
when installing on the vacuum pump/compressor
cover or near a wall.
CAUTION
To ensure sufficient cooling of the pump-motor
unit, also observe the following:
 Ventilation screens and openings must
remain clear.
 Discharge air of other units may not be
directly sucked in again!
Noise radiation:
To reduce the noise radiation, the following must
be observed:
 Do not mount pump-motor unit on noise-
conducting or noise-radiating parts (e.g. thin
walls or sheet-metal plates).
 Provide pump-motor unit with sound-insulating
intermediate layers (e.g. rubber buffers under the
base of the pump-motor unit) if necessary.
 Install the pump-motor unit on a stable
foundation or on a rigid mounting surface.
This provides for smooth, low-vibration
running of the pump-motor unit.
