5.2 Mechanical installation
• The pump is designed to be installed pumping upwards or
downwards.
• Arrows on the pump housing indicate the liquid flow direction
through the pump.
• If the pump is installed horizontally, the conduit box must point
downwards. Be aware that the pump connection, flange or
union nut, might interfere with the control box.
When making pipe connections, follow the piping manufacturer's
recommendations and all code requirements for the piping
material.
• Insert the check valve, if required.
• Refer to the arrows on the pump housing that indicate the
direction of the liquid flow through the pump.
• Install the pump with horizontal motor shaft.
• Fit gaskets to the pump ends.

The pump must always be installed with horizontal
motor shaft within ± 5 °.
The pump should be installed in the system in such a
way that no major amount of air flowing through the
pump or gathering in the pump housing will affect the
pump when it is out of operation.
If, in addition, a check valve is installed in the flow
pipe, there is a high risk of dry running as the air
cannot pass the valve.
