Finding Faults

Important! Unplug the pump. Check the pump for possible faults such as:

➔ Faulty or leaking back-flow

preventer at the end of the

suction hose

liquid to be pumped

➔ Backflow valve switch set

to position 2 and was not set

to position 1 once the pump

began pumping

➔ Suction hose end is not sub-

merged into the liquid

➔ Outlet too low

➔ Suction hose or connections

are not water-tight

➔ Suction filter clogged

➔ Air cannot escape on delivery

side since release points are

closed etc.

➔ Delivery pipe or consumer are

not water-tight

pump switches on and off more

than 7 times within 2 minutes,

the control unit issues a warn-

ing via flashing LEDs and the

motor switches itself off.

Clear the fault. Plug in the pump in order to start again operation of the pump.

Shouldn’t the pump start prim- ing, although you have repeat- edly pressed the RESET button, please contact one of our GARDENA Service Centres (addresses you will find on the rear side).

The temperature of the liquid to be pumped must not exceed

35 °C.

Sand and other abrasive sub- stances in the liquid cause increased wear and reduce the pump’s output.

The pump is not designed for continuous operation (e.g. industrial application, continu- ous circulating operation). The minimum flow rate is

90 I/h (= 1.5 I/min). Watering accessories with lower rate must not be operated.

. When using the pump for pres- sure intensification, the max. permissible internal pressure of 6 bar (on the delivery side) must not be exceeded.

The to be increased delivery pressure and the pump pres- sure sum up.

Example: pressure at the water tap 1.5 bar, max. pressure of the GARDENA Pressure Tank Unit 4000/4 electronic plus 4.2 bar, total pressure 5.7 bar.

Attention! Disconnect Athe plug from the mains before carrying out any work on the pump!

A turbine clogged by contamina- tion can be released by using a screwdriver to turn over the turbine axle B (observe the arrow on the casing indicating the direc- tion of rotation). If this is not pos- sible any more, the turbine space can be cleaned by opening the

screws 9 and removing the casing cover 0.

The turbine A can be removed if necessary, by using a screw- driver to hold the turbine axle B in place while loosening the turbine A with a ring spanner at the same time.

When assembling, take care that the parts are re-assembled cor- responding to the sequence of the disassembly.

Before the first frost sets in, the pump should be drained via the water drain screw 1. Store it protected from frost.

To empty the Electronic Mano- metric Switch 5 put the rotary switch C in position 2 and open the water drain screw 1.
