Pressure Switch:
Don't use any hose connection system fittings on the suction side!
A vacuum-resistant suction hose must be used
• e.g. GARDENA Suction Unit, Art. no. 1411.
To shorten the time required for suction to start again, we recom-
mend the use e.g. of the GARDENA suction filter with backflow
preventer, Art. 1728, combined with the GARDENA suction hose,
Art. 1412, which prevents the suction hose emptying automatical-
ly when the automatic domestic water systems are shut down.
Remove the flat gasket of the suction hose and replace it with
the dirt filter provided.
Alternatively, you can also use the GARDENA Pump
Preliminary Filter, Art. no. 1730/1731.
It is important to filter the water to prevent contaminating the
manometric switch.
The 33.3 mm (G1) inner thread at the outlet of the Electronic
Manometric Switch can be modified if necessary to an outer thre-
ad by using the GARDENA Pump Fitting, Art. No. 1745, which
can be fitted to the GARDENA Water Hose Connection System.
For pumps fitted with an horizontal 33.3 mm (G 1) outer thread we
recommend the use of the GARDENA Brass Angle with inner thre-
ad, Art. No. 7281. The connections have to be sealed with com-
mercial agents.

Disconnect the Electronic Pressure Switch from
the mains before filling it.

3. Fill with liquid to be pumped via the outlet pipe

4. Open any shut-off devices in the delivery line (watering acces-
sories, water stop, etc.) so that air can escape before the pri-
ming procedure begins.
5. Drain remaining water in pressure hose so that air can escape
during the suction process.
The mains plug of the pump must be plugged into the
manometric switch!
6. Switch ON/OFF switch of pump (if present) to "ON".
7. Plug the pump into a 230 V/50 Hz alternating current socket
