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,

Minimum distances:

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 minimum distances to the face of the vacuum pump/compressor cover are 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:

 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.

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,
