1. Clean the pump housing with a damp cloth.
2. Clean the airflow slots with a soft brush (do not use sharp objects).
4.2 To flush the pump:
After pumping chlorinated water, the pump must be flushed.
1. Pump through lukewarm water (max. 35 °C), possibly adding a mild
cleaning agent (e. g. detergent) until the pumped water runs clear.
2. Dispose of the residues in accordance with local waste disposal
regulations.
5. STORAGE
5.1 To put into storage [ Fig. S1 ]:
CAUTION!
Damage to the pump due to frost!
v Store the pump in a frost-free place.
The product must be stored away from children.
1. Unplug the plug of the mains cable from the mains socket.
2. Close any shut-off valves in the suction line.
3. Open any shut-off valves in the pressure line (accessories, water
stop, etc.).
Therefore the pressure line is depressurized.
4. Unscrew the screw fitting
5
of the filler neck
6
and the water drain
screw
8
by hand.
Therefore the pump is drained.
5. Tilt the pump in the direction of the drain (approx. 80°) so that the
pump empties completely.
6. Unscrew the suction hose and the pressure hose.
7. Tighten the screw connection
5
on the filling opening
6
and the
water drain screw
8
by hand (do not use pliers).
8. Clean the pump (see 4. MAINTENANCE).
9. Store the pump in a dry, enclosed and frost-free place.
6. TROUBLESHOOTING
DANGER!
Risk of injury!
Risk of injury due to accidental starting.
v Unplug the plug of the mains cable from the mains socket.
6.1 To loosen the impeller [ Fig. T1 ]:
An impeller blocked by dirt can be loosened.
v Turn the shaft of the impeller
9
clockwise with an insulated screw driver.
Therefore the blocked impeller is loosened.
6.2 Troubleshooting table:
Problem Possible Cause Remedy
Pump is running,
but the suction action
doesn’t take place
Leaky or damaged suction line
[Fig. A2].
v Check the suction line
for damage and seal so
is airtight.
Pump sucks in air at a con-
nection point [Fig. A2].
v Seal the suction side con-
nections airtight.
No water available in
the cistern,water tank,
water pipe, etc.
v Make sure that the water
supply is on the suction side.
Pump was not filled with water
[Fig. A4].
v Fill the pump
(see 3.1.1 To start the
pump).
Water escapes during the
suction process via the
pressure hose.
1. Fill the pump again.
2. Hold up the pressure hose.
3. Start the pump again
(see 3.1.1 To start the
pump).
Problem Possible Cause Remedy
Pump is running,
but the suction action
doesn’t take place
Absolutely vacuum-resistant connection is achieved by
using GARDENA Suction Hoses (see 8. ACCESSORIES /
SPARE PARTS).
Screw fitting on the filler neck
is leaking [ Fig. A2 ].
v Check the seal (replace
ifnecessary) and tighten
the screw fitting by hand
(do not use pliers).
Air cannot escape, since the
delivery line is closed or
remaining water is in the
pressure hose.
v Open any shut-off valves
(e. g. nozzle) in the delivery
line, or drain the pressure
hose.
Air cannot escape because the
pressure hose is coiled.
1. Lay out the pressure hose
straight along its entire
length.
2. Lay the hose from the pump
outlet upwards.
3. Do not kink the pressure
hose at the pump outlet.
4. Open all consumers maxi-
mum.
Suction time of 5 min. was
not waited for.
v Wait up to 5 minutes for the
pump to pump water.
Suction filter or backflow
preventer in the suction hose
are clogged.
v Clean the suction filter or
the back flow preventer.
The end of the suction hose is
not in the water [Fig. A5].
v Submerge the end of the
suction hose deeper in the
water.
Suction height is too high
[Fig. A5].
v Reduce the suction height.
In case of any other difficulties concerning the suction action,
use GARDENA Suction Hoses with Backflow Preventer
(see 8. ACCESSORIES / SPARE PARTS). Fill the pump with
water before starting it.
Pump does not start,
or stops suddenly during
operation
Thermal switch has turned
the pump off because of over-
heating.
v Let the pump cool down,
empty the pump and fill it
again.
v Observe the max. media
Temperature (35 °C).
No power supply to the pump. v Check the fuses and electrical
plug connections.
RCD has triggered
(residual current).
v Unplug the plug from the
mains socket and contact
the GARDENA Service.
Pump is not switched on. v Push the On / Off switch to the
position On.
Pump is running,
but the delivery
drops suddenly
The end of the suction hose is
not in the water [Fig. A5].
v Submerge the end of the
suction hose deeper in the
water.
Suction filter or backflow
preventer in the suction hose
are clogged.
v Clean the suction filter or the
back flow preventer.
No water available in the
cistern, water tank, water
pipe, etc.
v Make sure that the water
supply is on the suction side.
Suction line is leaking [Fig. A2]. v Eliminate the leak.
Impeller is blocked. v Loosen the impeller.
Pressure hose is kinked. v Lay the pressure hose with-
out kinks and do not kink the
pressure hose at the pump
outlet.
NOTE:
Repairs must only be done by the GARDENA service departments or
specialist dealers approved by GARDENA.
v For any other malfunctions please contact the GARDENA service
department.
