The GARDENA Garden Pump is essentially maintenance-free.
The pump must be flushed through after discharging chlorinated
swimming pool water.
1. Pump through lukewarm water (max. 35 °C), possibly adding a
mild cleaning agent (e.g. detergent) until the pumped water
runs clear.
2. Remove residuals according to the waste disposal laws
applicable in your area.
DANGER ! Electric shock !

Probable cause
Pump draws in air at a joint.
Leaky or damaged suction hose.
The pump was not filled with
the liquid to be pumped.
The liquid escapes over the
hose which is connected to the
delivery side during the suction
action.
Absolutely vacuum-resistant connection is achieved by using
GARDENA Suction Hoses (see point 8. Accessories).
Leaky screw fitting
cap
.
Air cannot escape, since delivery
side is closed or remaining water
is in the pressure hose.
The waiting time wasn't
observed.
Suction filter or backflow
preventer in the suction hose
clogged.

the pressure hose approx.
1 m vertically above the
pump, until the suction action
has taken place.
➔ Check seal (replace if neces-
at the filler
sary) and tighten connection
securely (do not use pliers).
➔ Open all possible shut-off
devices (e.g. spray nozzle) in
the pressure line, or drain the
pressure hose or disconnect
it during the suction action.
➔ Switch on the pump and wait
ca. 5 min.
➔ Clean the filter or the back
flow preventer.
