Alternatively, spring mounted feet (Art. 1753-00.901.00) for low vibration

and quiet running are available as accessories via the GARDENA Service.

Install the pressure tank unit so that there is room to place a suitably sized

drainage tray under the drain screw

drained.

If possible, install the unit higher than the surface of the water to be

pumped. If this is not possible, install a vacuum-resistant valve between

the unit and the suction hose, for example for cleaning the integrated filter.

If the pump is permanently installed indoors for domestic water supply,

the Pressure Tank Unit should not be connected to the domestic water

pipework with rigid pipes but with flexible tubing, to reduce noise and to

avoid damage to the pump caused by pressure blows.

If the system is being installed permanently, please fit suitable valves on

both the intake and delivery sides. This is important e. g. for maintenance

and cleaning work or if the system is being shut down.

The connection pieces on the intake and delivery sides may only

be tightened by hand.

Connect the hose to the suction side [ Fig. I2 ]:

A vacuum-tight suction hose must be used e. g.:

– GARDENA Suction Unit Art. no. 1411 / 1418 / 1412 or

– GARDENA Bore Hole Suction Hose Art. no. 1729.

Do not use any water hose snap connection system components on the

intake side!

v Connect the suction hose

connection

of the pump.

Connect the suction hoses

without a threaded connector via a connec-

tion piece (e.g. Art. no. 1723/1724)

and screw in place so that they are airtight.

To reduce the pump repriming time, we recommend using a suction hose

with backflow preventer, which prevents the suction hose emptying auto-

matically when the Pressure Tank Unit is switched off.

For suction heights exceeding 4 m also secure the suction hose

(e. g. by fastening it to a wooden post) to relieve the pump of the weight

of the suction hose.

If very fine dirt is present in the pumping medium, we recommend the

use of a GARDENA Pump Preliminary Filter Art. no. 1730 / 1731.

Connect hose to the output side [ Fig. I3 ]:

Note:

Use pressure-tight GARDENA hoses, 19 mm (3/4") in diameter, in

connection with the GARDENA Quick-Release Threaded Connector with

33.3 mm (G1) internal thread, Art. no. 7109, and the GARDENA Suction

and High Pressure Connector, Art. no. 7120, for 19 mm (3/4") hoses

and a GARDENA Hose Clip, Art. no. 7192.

Under no circumstances use these hoses on the suction side.

v Connect delivery hose

to the delivery side connection

v Tip: If permanent pipes are installed, they must be laid at an ascending

angle in order to allow the water to flow back into

the pump on the pressure side.

3. OPERATION

Starting the Pressure Tank Unit [ Fig. O1 / O2 / O3 ]:

DANGER! Electric shock!

v Before filling the pump, unplug the equipment from the

mains.

CAUTION! Pump running dry!

v Fill the pump to the overflow (approx. 2 to 3 l) with water each

time before the pump is switched on, so it does not run dry.

1. Unscrew the cover

of the filter chamber by hand.

2. Turn the rotary switch

to FILL.

The integrated non-return valve will open.

3. Open the air bleed

4. Open any valves in the delivery line (watering accessories, water stop,

etc.) and drain off any residual water in the delivery hose so that the air

can escape during filling and priming.

5. Slowly pour pumping medium (approx. 2 to 3 l) through the filler

neck

until water emerges from the air bleed

6. Screw the filter chamber cover

closed again, turning by hand until it

7. Close venting

and turn rotary switch

8. Insert the mains plug into a 230 V mains socket.

CAUTION! The pump will start immediately!

Once the maximum pressure is reached the pump will switch off automati-

cally. When the pressure falls below the minimum value due to water being

drawn off, the pump will switch on again automatically.

The maximum self-priming head of 8 m is only achieved if the pump is fil-

led until it overflows from the filler connection

held high enough during self-priming so that no water can escape from

the pump via the delivery hose. It is not necessary to hold up the delivery

hose if filled suction hoses with backflow preventer are used.

ECO switch [ Fig. O4 ]:

In order to save energy (up to 15 %), the cut-out pressure on the pump

can, depending on the individual application, be regulated between ECO

and MAX (the pressure difference between ECO and MAX totals

approx. 1 bar).

v Turn the ECO rotary switch

Note on the use of sprinklers:

Depending on the flow rate of the sprinkler, an uneven watering pattern

may occur through the pump being switched on and off automatically.

4. STORAGE

To put into storage [ Fig. S1 / O1 ]:

If there is a risk of frost, the Pressure Tank Unit must be emptied

and stored where it will not become frozen. The product must

be stored away from children.

1. Unplug the mains connection for the pump.

2. Turn the rotary switch

3. Open the delivery side consumer.

4. Unscrew the end cap

5. Store the pressure tank unit in a dry, frost-free place.

Disposal:

(in accordance with RL2012/19/EC)

The product must not be disposed of to normal household waste.

It must be disposed of in line with local environmental regulations.

IMPORTANT!

v Dispose of the product through or via your municipal recycling

collection centre.

5. MAINTENANCE

DANGER! Electric shock!

v Pull out mains plug before undertaking any maintenance.

Clean suction filter [ Fig. M1 / O3 / M2 ]:

1. Turn the rotary switch

2. If necessary, close all the shut-off devices on the intake side.

3. Unscrew and remove cover

4. Draw out filter unit

5. Hold beaker

firmly, turn filter

(bayonet fitting).

6. Clean beaker

under running water and clean the filter

a soft brush.

7. Refit filter again in reverse order.

Cleaning the check valve [ Fig. M3 / O1 ]:

1. Turn the rotary switch

2. If necessary, close all valves on the intake side.

3. Open all pressure side outlets, so that the pressure side is

depressurised.
