• Close shut-off devices or drain the heating system.
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).
CAUTION!
An incorrect installation position may damage the
