INSTALLATION AND CONNECTION

N O T E
For permanent installation of the pump,
use flexible compression-proof hoses to
connect it to the pipe network to reduce
the noise of the pump.
Install the pump in a horizontal and sta-
•
ble position in a dry place.
– For permanent installation of the
pump, ensure that a sufficiently large
collecting basin can be positioned
underneath the discharge screw for
emptying the pump.
If possible, install the pump in a higher
•
position than the container/reservoir
from which the water is to be pumped. If
this is not possible, a pressure-proof
valve must be fitted between the pump
and the suction hose.
Only use vacuum-proof pressure hoses
•
on the pressure and suction side.
N O T E
OASE recommends: Additionally fasten
the suction hose (e.g. by tying it to a
wooden stake) to relieve the weight of
the hose on the pump.
 B
Screw a suction and pressure hose with
•
25.0 mm internal diameter (1") onto the
connections.
OPERATION
Start-up of the device
It is necessary to fill the pump and expel
the air from the suction line before using it
for the first time. It can take several
minutes to expel air from the suction line.
How to proceed:
 C
1. Unscrew the filter cover. A screwdriver
can be inserted from the side into the re-
cesses of the cover to aid unscrewing.
2. Open the shut-off device in the pressure
line.
3. Pour water into the infill opening of the
pre-filter until it overflows. At the same
time, keep the non-return valve opener
open until the water has expelled any
remaining air from the filter.
4. Screw the filter cover back on.
5. Insert the power plug into the socket.
– The pump is ready for operation.
6. Switch on the pump. (→ Operation)
– The pump starts pumping immedi-
ately. The emerging water still con-
tains some air.
N O T E
If no water is taken in after 5 minutes, the
dry run protection of the pump is acti-
vated.
7. Close the shut-off device of the pres-
sure line as soon as there is no more air
in the emerging water. Air has now been
expelled from the suction line.
Shutting down the pump
N O T E
Rinse out the pump with clean water after
use.
How to proceed:
1. Switch off the pump
2. Disconnect the power plug.
3. Depressurise the pressure line by open-
ing the water withdrawal points.
4. Also open any non-return valves fitted in
the suction line.
– When the pump is switched off, re-
sidual water in the hose may flow
back and out of the pump intake.
If the pump is to be completely removed:

5. Remove the connected hoses on the
pressure and suction side.
