under flowing water.
3. Replace seal (Fig. C -23) if necessary.
4. Fit check valve.
Unscrew float body
1. Pressure line (Fig. B -13), with elbow nipple
(Fig. B -14), and connecting nipple (Fig. B -16)
.
2. Unscrew screw-in nipple (Fig. D -25) with seal
(Fig. D -26) . Note the fitting position of the

HELP IN CASE OF A MALFUNCTION

CAUTION!
Disconnect the mains plug before any fault rectification work. Faults in the electrical system
must be rectified by an expert electrician.
Malfunction
Pump motor does
not run
Pump not drawing
water
467776_d
Cause
Impeller blocked
Overheating by running dry or water
which is too hot (thermal protection
switch has switched the pump off).
No mains voltage
The suction line is not in the water.
5. Check that the pump is running freely by swit-
ching it on briefly.
6. Start the house water system again as descri-
bed.

STORAGE

If there is a risk of frost, the entire sys-
tem must be drained (pump, lines, sto-
rage vessel and filter chamber).
1. Drain the suction line (Fig. B -18) and the
pressure line (Fig. B -13).
2. Unscrew the drain screw on the filter chamber
(Fig. A -10) and allow the water to flow out of
the pump.
The water in the storage vessel (Fig. A
-6) is pushed out by the air bellows at the
same time.
3. Unscrew the drain screw on the pump cham-
ber (Fig. A -9) and allow the storage vessel
(6) to empty.
4. Screw the drain screws (Fig. A -9, 10) back in
position and store the pump, lines and storage
vessel in a frost-free environment.

DISPOSAL

Do not dispose of worn-out machines
or spent batteries (including recharge-
able batteries) in domestic waste!
The packaging, machine and accessories
are made from recyclable materials and
must be disposed of accordingly.
Rectification
Cleaning the pump.
Release the motor shaft of the impeller
with a screwdriver.
Check the water level on the suction
side. Allow the conveying fluid to cool
down. Repair the pump or replace it.
Check fuses and power supply.
Submerge the end of the suction line
into the water by min. 30 cm.
