3.2 Pump location

Pumps without or with float switch can be used in

vertical position with the discharge port uppermost or

in horizontal or tilted position with the discharge port

as the highest point of the pump, see fig. 6.

Pumps with vertical level switch must be used in ver-

tical position.

Fig. 6

When the pipe/hose has been connected, the pump

is ready for use.

Note: Do not lift the pump by means of the electric

cable. Lift the pump by means of the discharge pipe/

hose or a wire secured to the handle of the pump.

Before positioning the pump, make sure that the suc-

tion strainer will not be blocked or partly blocked by

silt, mud or similar materials.

This can be avoided by positioning the pump on

bricks, an iron plate, etc., see fig. 7.

3.3 Adjustment of float switch

The difference in level between start and stop can be

adjusted by changing the free cable length between

the handle of the pump and the float switch.

Large difference in level: long free cable. This ca-

ble length must not exceed 150 mm, see fig. 8.

Fig. 8

* For KP 350 the distance between the bottom of the

suction strainer and the lowest level of the float is

110 mm.

Small difference in level: short free cable. This ca-

ble length must at least be 70 mm, see fig. 9.

suction strainer and the lowest level of the float is
