9.2 Pump location

The pump can be used in the vertical position and in
the tilted or horizontal position with the discharge
port as the highest point of the pump.
During operation, the suction strainer must be
covered by the pumped liquid.

Position the pump so that the suction strainer is free
of silt, mud or similar materials. This can be ensured
by placing the pump on bricks, an iron plate, etc.

9.3 Connection of discharge pipe

The discharge pipe can be connected directly to the
pump discharge port or by means of the adapter.
To prevent backflow through the pump when it stops,
the non-return valve supplied can be fitted inside the
adapter.
Fig. 6 Adapter and non-return valve
(position and function)
The adapter enables the connection of a pipe or
hose matching ¾", 1" and 1¼" NPT external pipe
thread. Cut off the adapter so that it matches the
discharge pipe diameter. If a gasket is used between
the discharge pipe and the adapter, the cut-off
adapter must have an even and smooth surface.
Please comply with local standards when connecting
the multifunctional adapter supplied to a pipe in a
permanent installation.
