Installation
CAUTION
Danger of tripping and falling!
Make sure the unit does not present a danger
of tripping.
Lay cables and pipes so that they cannot be
reached during operation(recessed in floor, in
ducts on the wall etc.).
CAUTION
Danger of overheating due to hot surface of
pump-motor unit!
High temperatures can occur on the surface of
the pump-motor unit.
Temperature sensitive parts, such as lines or
electronic components, may not come into
contact with the surface of the pump-motor
unit.
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. 20 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,
•

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. 7 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. 7.
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.
