CAUTION! Risk of material damage!
Provide adequate ventilation/heating in situations where the permitted
ambient temperature is exceeded or fallen short of.
• Carry out all welding and soldering work prior to the installation of the pump.
CAUTION! Risk of material damage!
Contamination from the pipe system can destroy the pump during operation.
Before installing the pump, flush the pipe system.
• Provide shut-off devices upstream and downstream of the pump.
• Attach piping to the floor, ceiling or wall using appropriate fittings so that the
pump does not bear the weight of the piping.
• When installing in the feed of open systems, the safety supply must branch off
upstream of the pump (DIN EN 12828).
• If necessary remove the two half shells of the thermal insulation before install-
ing the single pump.
• Install the pump at an easily accessible location to allow it to be easily checked
or replaced at a later time.
• Precautions during installation:
• The pump shaft should be installed free from stress and in a horizontal posi-
tion (see installation positions according to Fig. 2). The motor terminal box
must not point downwards. If necessary, slacken the internal hexagon head
screws and rotate the motor housing (see section 9).
• The direction of flow of the fluid must correspond to the flow direction sym-
bol on the pump housing or the pump flange.
7.1.1 Installation of a threaded pipe union pump
• Install appropriate threaded pipe unions before installing the pump.
• Use the supplied flat gaskets between the suction/pressure ports and threaded
pipe unions when installing the pump.
• Screw the union nuts onto the thread of the suction/discharge port and tighten
with a suitable open-end wrench or pipe wrench.
CAUTION! Risk of material damage!
When tightening the pipe unions, keep the pump in position by gripping the
motor. Not the module/terminal box!
• Check the threaded pipe unions for impermeability.
• Single pump:
Fit the two half-shells of the thermal insulation before commissioning and push
them together so that the guide pins engage in the opposing holes.
