Avoid running of the pump for more than 10 min. against closed
delivery side of the pump.
Sand and other abrasive substances cause increased wear and
reduce the pump’s output.
Take care that the pump is located where the inlet openings at
the suction base are obstructed neither completely nor partly.
Stand the pump on a brick if using in a pond.
The pump is automatically switched off on overheating by
the built-in thermal motor protector. After having cooled down,
the motor automatically switches on again (see 6. Trouble
Shooting).
The automatic deaerating valve eliminates any air pockets in
the pump. If the water level drops below the vent valve, some
water flows penetrates outside through the vent valve
4
.
This is not a defect of your pump, but serves to deaerate the
pump.

The universal fitting

allows you to connect all the hoses listed
in the previous table.
1. Cut off nipples of the universal fitting
7
, which are not needed,
to match the hose connection.
2. Screw the universal fitting

onto the pump.
3. Connect the hose to the universal fitting

The universal fitting
7
can also be equipped with a
GARDENA
Regulator Valve Art. No. 977
so that the contents of the out-
let line do not flow back through the pump after pumping.
The Regulator Valve can be ordered from GARDENA Service.
4. Operation
To ensure that the pump draws the water out, the water to be
drained must be at least 45 mm deep.
The float switch
5
turns the pump on automatically when the
water level exceeds the cut-in height and the water is pumped out.
The float switch
5
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 to the carrying handle
2
to immerse the
pump in a well or shaft.
During automatic operation, ensure that the float switch
5
can move freely.
2. Plug the power cable
1
into a mains socket.
Adjusting the Cut-in and Cut-out Height :
The maximum cut-in height and minimum cut-out height (see
8. Technical Data) can be adjusted.
v
Push the cable of the float switch
5
into the float switch lock
3
.
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 shorter the length of cable between the float switch
5
and the float switch lock
3
, the lower the cut-in height and the
higher the cut-out height.
The pump remains in constant operation because the float switch
is bypassed.
1. Stand the pump on a firm surface
– or –
use a rope attached to the carrying handle
2
to immerse the
pump in a well or shaft.
2. Plug the power cable
1
into a mains socket.
3. Fix float switch
5
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 residual water height of approx. 5 mm is only reached
during manual operation since the float switch turns off the
pump during automatic operation before this water level is
reached.
