6.2 How to place the pump

Unilift KP-A and Unilift KP-M can be used in vertical
position with the discharge port pointing upwards.
The pumps may also be used in horisontal or tilted
position with the discharge port as the highest point.
See fig. 4.
Fig. 4 How to place Unilift KP-A and
Unilift KP-M
Always place Unillift KP-AV in vertical
Caution
position.
Place the pump so that the suction strainer is not
covered in sludge, mud or similar materials. This can
be ensured by placing the pump on bricks, an iron
plate, or similar. See fig. 5.

6.3 Connection of discharge pipe

Fit the discharge pipe or hose in the Rp 1¼
discharge port. Steel pipes can be screwed directly
into the pump discharge port.
In case of a permanent installation, fit a union to the
discharge pipe to facilitate mounting and removal. If
a hose is used, fit a hose union.
The pump must not be installed
Caution
hanging from the discharge pipe.
In a permanent installation with level switch, fit a
non-return valve to the discharge pipe or hose.
