Preparation Installation within a building:
• Install the pump in a dry, well-ventilated, frost-free
room.
Installation outside a building (outdoor installation):
• Install the pump in a chamber with cover or in a cabi-
net/housing as weather protection.
• Avoid exposure of the pump to direct sunlight.
• Protect the pump against rain.
• Keep the motor and electronics continually ventilated
to avoid overheating.
• The permitted fluid temperatures and ambient tem-
peratures should not be exceeded or undershot.
• Choose an installation point that is as easily accessible
as possible.
• Observe the pump’s permitted installation
position (Fig. 2).
• Install shut-off devices upstream and downstream of
the pump to facilitate pump replacement.
WARNING!
Risk of scalding from hot fluids!
Hot fluids can cause scalding. Before installing or
removing the pump, or loosening the housing
screws (4), note the following:
• Allow the heating system to cool down completely.
• Close shut-off devices or drain the heating system.
CAUTION!
An incorrect installation position may damage the
pump.
• Select the installation point in line with the permis-
sible installation position (Fig. 2).
• The motor must always be installed horizontally.
• The electrical connection must never face upwards.
