safety switch can be used.
➔ Please ask your electrician for his advice.
Data indicated on the type plate must match
the technical data of the mains supply.
Pursuant to DIN VDE 0620 the power cable as

General Information:
Risk of injury due to hot water !
If the pressure switch is defective and the
pressure tank unit runs for an extended
period (> 5 min) when the pressure side
outlets are closed, the water in the pressure
tank unit can become heated so that hot
water can emerge from the outlet and
cause injuries.
➔ Pump may only run for max. 5 min with
the discharge side closed.
If the water supply on the intake side of the
pump fails, the water in the pump can heat
up so that if water emerges, injuries could
be caused by the hot water.
➔ Disconnect pump from the mains, allow
water to cool down and ensure the water
supply is functioning correctly before
starting the pump again.
➔ Before operating the pressure tank unit, first
make a visual check to ensure there is no
damage to the pressure tank unit (especially
regarding power cable and plug).
A damaged pressure tank unit must not be used.
➔ In case of damage, please have the pressure
tank unit checked by our GARDENA Service
Centre or by an authorised electrician.
Protect the pump from rain. Do not use the
pressure tank unit in a wet or moist area.
In order to avoid dry-running of the pressure
tank unit, take care that the end of the suction
hose is always submerged into the liquid.
The pressure tank unit must not be run dry nor
with the stopcock in the suction pipework clo-
sed.
➔ Before each operation, fill the pressure tank
unit to overflowing with approx. 2 to 3 l of
the liquid to be pumped!
Sand and other abrasive substances in the
liquid cause increased wear and reduce the
pump's output.
When using the pump for domestic water
supply, please adhere to the local water and
sewerage regulations. In addition observe the
regulations of DIN 1988.
➔ If necessary contact your local water
authority.
