7.1 Installation
• Install pump only after completion of all welding/soldering
and after the pipe system had been thoroughly flushed out.
• Mount the pump in an easily accessible location in order to
facilitate later inspections or exchange.
• When installed in the flow pipe of an open-vented system,
the safety vent must be connected on the inlet side of the
pump.
• Isolating valves should be provided and installed at both suc-
tion and discharge ports of the pump in order to facilitate a
possible pump exchange. They must be located in such a way
to prevent valve spindle leakage from spilling onto the con-
trol module (upper valve turned sideways).
• Install pump free of stress and with the motor shaft horizon-
tally located. For module locations refer to Fig. 3. Other
arrangements on request.
• Directional arrows on pump body and the insulation shell
indicate the direction of flow.
• If the mounting location of the module is to be altered, turn
the motor housing as follows:
