Extension cables
The Electronic Pressure Switch may only be
operated with 230 V / 50 Hz.
Note mains voltage.
Pursuant to DIN VDE 0620, power cable as
well as extension cables must not have a
smaller diameter than rubber sheathed cables
described with letter symbols H07 RNF.
Ensure that the plug and socket connections
are arranged in an area which cannot flood.

Always inspect before use to ensure that the
equipment, especially the plug and the
cable, are not damaged.
A damaged unit must not be used.
If damaged, have the Electronic Pressure
Switch checked by GARDENA Service or an
authorised electrician.
The Electronic Manometric Switch is equipped with an electronic
control unit with fixed programs. The electronic control unit is acti-
vated by pulses from the manometric switch and the flow recogni-
tion of the dry-running safety feature.
The manometric switch is set at the factory to a switching pressu-
re of approx. 2.2 bar. This setting cannot be changed. The dry-
running safety mechanism protects the pump against damage and
controls the time the pump continues to run against the closed
delivery side.
Explanation of terms
The pump has reached the maximum pump pressure and switches
off automatically.
The pump attempts to resume normal operation after 4 minutes.
After a fault, the pump's electronic control unit makes three auto-
matic self-priming attempts at different time intervals (after 1 hour,
after 5 hours and after 20 hours) to restore normal operation. The
priming cycle (see above) is used for each of these attempts.
You can switch the pump on again prematurely at any time by
pressing the RESET key. If the warning LED is flashing, however,
the pump can only be turned on again by unplugging the mains
plug and then plugging the plug back in again.
