CAUTION! Risk of damage!
Contamination from the pipe system can damage the pump during operation.
Before installing the pump, flush the pipe system.
• Provide shut-off valves upstream and downstream of the pump.
• Attach pipework to the floor, ceiling or wall using appropriate fittings so that
the pump does not bear the weight of the pipework.
• If installed at the inlet to an open system, the safety inlet must branch off at the
pump's discharge side.
• If necessary remove the two half shells of the thermal insulation before install-
ing the single-head 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:
• Perform assembly such that the pump shafts are horizontal and not under
strain (see the installation positions shown in Fig. 2). The motor terminal box
must not face downward. If necessary, slacken the socket-head screws and
rotate the motor housing (see chapter 9).
• The direction of flow of the fluid must correspond to the direction arrow on
the pump housing or the pump flange.
7.1.1 Installation of a threaded pipe union pump
• Install appropriate pipe unions before installing the pump.
• Use the supplied flat gaskets between the suction/pressure ports and pipe
unions when installing the pump.
• Screw union nuts onto the threads of the suction/pressure ports and tighten
them using a monkey wrench or pipe wrench.
CAUTION! Risk of damage!
When tightening the pipe unions, keep the pump in position by gripping the
motor. Not the module/terminal box!
• Check the pipe unions for leaks.
• Single-head 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.
