4. Operation
Automatic operation:
The float switch
ቤ
turns the pump on automatically when the water
level exceeds the cut-in height and the water is pumped out.
The float switch
ቤ
turns the pump off again as soon as the water
level falls below the cut-out height.
1. Stand the pump on a firm surface
– or –
use a rope attached through the bore hole in the carrying
handle
ብ
to immerse the pump in a well or shaft.
During automatic operation, ensure that the float switch
ቤ
can
move freely.
2. Plug the power cable
ቦ
into a mains socket.
Adjusting the Cut-in and Cut-out Height:
(Minimum depth for switching on and off, see 8. Technical Data.)
➜ Push the cable of the float switch
ቤ
into the float switch lock
ቧ
.
Do not select a cable length that is too long or short to ensure
that the float switch can turn on and off properly.
The cable length between the float switch
ቤ
and the float switch
lock
ቧ
must always be at least 10 cm.
• The shorter the length of cable between the float switch
ቤ
and
the float switch lock
ቧ
, the lower the cut-in height and the
higher the cut-out height.
Manual operation: To ensure that the pump can draw in water, the level must be
above the minimum water level at start-up (see 8. Technical
Data).
The pump remains constantly in operation because it is switched
on manually by raising the float switch.
1. Stand the pump on a firm surface
– or –
use a rope attached through the bore hole in the carrying
handle
ብ
to immerse the pump in a well or shaft.
2. Plug the power cable
ቦ
into a mains socket.
3. Fix float switch
ቤ
vertically above the pump (with the cable
at the bottom).
As long as the float switch is positioned vertically above the
pump, the pump will operate regardless of the water level.
The minimum residual water depth (see 8. Technical Data) is
only achieved in manual mode because the float switch already
switches off the pump before this when in automatic mode.
