unplug the mains plug (see 6. Trouble Shooting).

When using the pump for pressure intensification, the max. per-
missible internal pressure of 6 bar (on the delivery side) must
not be exceeded. The to be increased delivery pressure and the
pump pressure sum up.

• Example: pressure at the water tap 1.5 bar, max. pressure of

the GARDENA Dual Pump 5000 / 3 SGP = 3.3 bar,  total pres-
sure = 4.8 bar.

The GARDENA Dual Pump is virtually maintenance-free.
