3.2.2 Lifting the pump
Do not pull or lift the product by the power cable.
Lift the pump using the pump handle. Do not lift the pump by the
power cable or by the outlet pipe or hose.
If the pump is installed in a well or tank, lower and lift it by means of
a wire or chain fastened to the pump handle.
3.2.3 Positioning the pump
UNILIFT KP-A and UNILIFT KP-M can be used in vertical position
with the outlet pointing upwards. The pumps may also be used in
horizontal or tilted position with the outlet as the highest point. See
fig. How to position UNILIFT KP-A and UNILIFT KP-M.
During operation, the inlet strainer must always be completely
covered by the pumped liquid.
TM001548
How to position UNILIFT KP-A and UNILIFT KP-M
Always place Unillift KP-AV in vertical position.
When the pipe or hose has been connected, place the pump in its
operating position.
Position the pump so that the pump inlet will not be blocked or
partly blocked by sludge, mud or similar materials.
In the case of permanent installation, the pit must be cleared of
sludge, pebbles, etc. before the pump is installed.
