individual pump noise value from the installation
and operating instructions for the pumps or from
the catalogue information on the pumps.

7 Installation

7.1 Installation location

• The system is installed in the technical control
room or in a dry, well ventilated and frost-proof,
separate room that can be locked (requirement of
DIN 1988).
• Adequately dimensioned floor drainage (sewer
connection or similar) must be provided in the
installation room.
• No harmful gases must penetrate the room or be
present there.
• Adequate space must be provided for mainten-
ance work. The main dimensions are given on the
attached installation plan. The installation should
be freely accessible from at least two sides.
• The installation surface must be horizontal and
flat.
• The system is designed for a maximum ambient
temperature of +0 °C to 40 °C with a relative
atmospheric humidity 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
with extension limiters or flexible connecting
pipes should be used!
