Note 2: Best results regarding the delivery capacity of the pump are achieved when con- necting 19 mm (3/4 ”) hoses in conjunction with GARDENA “Profi” Maxi-Flow System fit- tings (e.g. art.no. 1752) or

When connecting simultane- ously several hoses / watering accessories, we recommend application of our GARDENA Twin-Tap Connector (art.no. 1210) or Four Channel Water Distributor (art.no. 1194) which can be screwed directly onto the pump fitting on the delivery side G.

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 mano- metric switch and the flow recog- nition of the dry-running safety feature.

The manometric switch is set at the factory to a switching pressure of approx. 2.2 bar. This setting cannot be changed. The dry-running safety mech-

6. Starting Operation

Using the pump for the first time

1.Set the switch of the backflow valve to Position 2.

2.Slightly open the release points in the delivery pipe (e.g. spray lance, tap) ➔ air must

be allowed to escape during the suction process.

3.Plug the mains plug D for the Electronic Manometric Switch into an outlet socket supplying 230 V alternating current.

Caution! The pump immedi- ately starts to run!

4.As soon as the pump begins to pump, turn the switch to Position 1 (normal operation)

In Austria, the electrical connections must be made according to ÖVE-EM 42,

T2 (2000)/1979 § 22 based on § 2022.1. Pursuant to this regulation it’s imperative to operate pumps for swimming pools and garden ponds exclusively via an isolating transformer. Please ask your electrician.

In Switzerland mobile appli- ances which are used out- doors, must be connected via a residual-current device. When using the pump for domestic water supply, please adhere to the local water and sewerage regula- tions. In addition observe the regulations of DIN 1988. If necessary, contact your sanitary expert.

. Children under the age of 16 are not allowed to operate the pump. Keep them away from the connected unit.

. Protect the pump from rain.

Don’t use the pump in wet or moist area.

. Before operating the pump, first make a visual check, if there is any damage of the pump (esp. regarding power cable and plug). A damaged pump must not be used. In case of damage, please have the pump checked by our GARDENA Service Centre or by an authorised electrician.

. Check line voltage. Data indicated on the type plate must match technical data of the mains supply.

The pump attempts to restore normal operation in 4 minutes.

. Automatic self-priming mode (➔ yellow Alarm LED flash- es)

After a fault, the pump’s elec- tronic control unit makes three automatic 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 at- tempts.

. Re-plugging (removing the mains plug and then plugging it back in the socket again) Important! Remove the plug from the socket! Check the unit and pump for any faults (see section “Finding Faults”). Rectify any faults and restart the pump by plugging the mains plug into a socket sup- plying 230 V AC.
