4. Measures Before Operation
4.1 Hose Connection
Screw the supplied fittings onto the pump, as described in illustration B.
The universal fitting (7) allows connection of 1¼” (32mm), 1” (25mm),
3/4” (19mm) as well as of 1/3” (13mm) hoses, according to your indi-
vidual requirements, 5/4” (32mm) hoses are connected to the pump via
the step nipples of universal fitting, 3/4” (19mm ) and 1/2” (13mm) hoses
with Hose connection system parts (illustration D). It is recommended to
fix 1¼” (32mm) and 1” (25mm) hoses additional with a hose clamp.
Components of the universal fitting which you don’t require (when con-
necting 1¼” (32mm) hoses are detached with a knife from the universal
fitting, illustration E.)
Best results in delivery capacity are achieved when using 5/4” (32mm)
hoses.
4.2 Float Switch Adjustment
The float switch (5) automatically switches on the pump at a water height
of approx. 21” (53cm) and automatically switches off at a water height
of approx 2” (5cm) by fixing the float switch cable to the float switch lock
(3). The cut-in/cut-out height can be adjusted individually.
4.3 Location and Transport
• Please take care that the pump is located in a stable position (especially
for automatic operation).
• In addition, pay attention that in case of automatic operation, the float
switch can move free.
• Take care that the pump is located in a way ensuring that the inlet open-
ings at the suctions base are obstructed neither completely nor partly.
Therefore, it is advisable to place the pump for example on a brick.
• Don’t use power cable or float switch for carrying or hanging up the
pump. When submerging the pump in wells or shafts, please use a rope
which is fastened to the pumps carrying handle (2).
