Connect pressure pipe
The use of rigid pipes with a non-return valve is recommended for use at a fixed location. This prevents return
flow of the liquid when switching off.
– Screw pressure line onto the pressure connection.
– When using a hose, screw the hose adapter onto the pressure connection.
– Push the hose firmly onto the hose adapter and secure with a hose clamp.
Installation
The appliance needs an area of at least 50 × 50 cm (the float switch must be able to move freely so that it func-
tions properly).
The appliance can be submerged under water up to the submerged operating depth mentioned in the technical
data.
Install the appliance so that the suction openings cannot be blocked by foreign bodies (place the appliance on
a firm, even base if necessary).
Ensure that the appliance is stable.
– Submerge the pump at an angle into the liquid to be delivered so that no air pocket forms on the underside
of the appliance. Suction would be prevented by this. Once the pump is submerged, it can be righted
again.
– Leave the pump on the bottom of the liquid container. Use a strong rope attached to the carrying handle
of the pump for lowering.
– Tighten the end of the rope firmly after lowering.
The pump can also be operated while suspended on a rope.
Note:
In the case of continuous use of the pump with the rope, the condition of the rope must be
checked regularly as it can decay and break over time.

NOTICE! Risk of damage to the appliance!
Do not lift the pump with the cable or pressure hose as
these are not designed for the tensile stress from the weight of the pump.
Note:
For operation with rope: Do not operate the pump without pressure hose. Avoid the pump
twisting around its longitudinal axis.
