6 OPERATION

6.1

Switching the pump on (2)

IMPORTANT!
Danger of damage to the
device
The pump must not draw
in any solids. Sand and
other abrasive materials in
the conveying medium will
destroy the pump.
■
Ensure that no solids
get into the conveying
medium.
NOTE
If the pump is placed on muddy, sandy
or stony ground, use a suitable plate to
ensure secure mounting.
1. Completely uncoil the mains connection
cable.
2. Make sure that the electrical plug connector
is attached in an area safe from flooding.
3. Change the terminal position and individually
adjust the switching points of the float switch
(8).
4. Securely clamp the cable of the float switch
on the pump housing. The recommended
cable length of the float switch is approx. 120
mm.
5. Slowly immerse the pump into the conveying
medium. Hold the pump at a slight angle to
allow any trapped air to escape.
6. Insert the mains power plug into the power
socket.
■
The immersion pump switches on automatic-
ally using the float switch when a specific wa-
ter level has been reached, and switches off
again if the water drops below the switch-off
height.
6.2

Switching the pump off

1. Remove the mains plug from the plug socket.

6.3

Pumping out to residual water level

IMPORTANT!
Danger of damage to the
device
When pumping out, there
is the danger that the
pump will run dry and
damage the device.
■
Monitor the pump con-
tinuously when pumping
out to the residual water
level and avoid the
pump running dry.
■
Take the pump out of
service when the resid-
ual water level is
reached by pulling out
the mains plug.
The float switch must be operated manually to
pump to the residual water level:
1. Remove the mains plug from the plug socket.
2. Place the float switch upwards and fasten it.
3. Insert the mains power plug into the power
socket. The pump switches on and starts to
feed.
NOTE
If the water drops below the residual wa-
ter level, the pump will draw air in. In this
case, the pump must be vented when
the water level rises and before using it
again.
