In the event of sound-pressure levels of above
80 dB(A), it is imperative that the operating per-
sonnel and persons who are nearby wear suita-
ble hearing protection!

7 Setup/installation

7.1 Installation site

• The pressure boosting system is installed in the
technical control room or in a dry, well ventilated
and frost-proof, separate room that can be locked
(e.g. as required by DIN 1988).
• Adequately dimensioned floor drainage (drain
connection or similar) must be provided in the
installation room.
• No harmful gases may enter the room or be pres-
ent there.

on the pumps. With the following procedure, it is
possible to approximate the overall noise level of
the complete system using the noise value for an
individual pump of the type supplied.

• Ensure adequate space for maintenance work!
The main dimensions can be found in the supplied
installation plan. The system should be freely
accessible from at least two sides.
• The installation surface must be horizontal and
flat. A slight adjustment in height of the vibration
absorber in the base frame may be necessary to
achieve stabilisation. If this is necessary, undo the
counter nuts and unscrew the respective vibration
absorber slightly. Then re-tighten the counter
nuts.
• The system is designed for a maximum ambient
temperature of +0 °C to 40 °C at a relative humid-
ity of 50 %.
• Installation and operation in the vicinity of living
rooms and bedrooms is not recommended.
• To avoid the transmission of structure-borne
noise and to ensure a stress-free connection to
upstream and downstream pipes, compensators
(Fig. 8, B) with extension limiters or flexible con-
nection pipes (Fig. 9, B) should be used.
