7.1 Installation
• Only install the pump after all welding and soldering work has
been completed and, if necessary, the pipe system has been
flushed through.
• Install the pump in a readily accessible place for easy inspection
and dismantling.
• When installing in the feed of open systems, the safety supply
must branch off upstream of the pump (DIN EN 12828).
• Install check valves upstream and downstream of the pump to
facilitate a possible pump replacement.
• Perform installation so that any leaking water cannot drip
onto the control module.
• To do this, align the upper gate valve laterally.
• In thermal insulation work, make sure that the pump motor and
the module are not insulated. The condensate-drain openings
must remain uncovered.
• Install with the power switched off and the pump motor in a
horizontal position. See fig. 3 for installation positions of the
pump.
• Direction arrows on the pump housing and the insulation shell
(can be ordered separately) indicate the direction of flow.
• If the installation position of the module is changed, the motor
housing has to be turned as follows:
