for the pumps or from the catalogue information
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.
• Adequately dimensioned floor drainage (drain
connection or similar) must be provided in the
installation room.
• No harmful gases may penetrate into the room or
be present there.
• Provide adequate space for maintenance work.
The leading dimensions can be found in the
accompanying installation plan. The system
should be freely accessible from at least two sides.
• Pay attention for adequate freedom of movement
to open the door of the controller (left side at look
towards the control panel) and for maintenance in
the control unit (at least 1000mm - see Figure 14)
