v Position the pump at a safe distance (min. 2 m) from the water.

The pump must be installed in a location with low air humidity and suffi-

cient ventilation in the area of the ventilation slots. It must be at a distance

of at least 5 cm from the walls. Dirt (e. g. sand or soil) must not be sucked

in through the ventilation slots.

The plastic connection pieces on the intake and delivery sides may

only be tightened by hand.

Fixed installation of the pump [ Fig. A1 ]:

A mounting plate

(12)

e. g. wooden plate (not included) prevents the pres-

sure tank unit from slipping.

v The Pressure Tank Unit can be screwed with all 4 feet

(12)

surface

(We recommend the use of inbus screws).

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 pump higher than the surface of the water to be

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

the pump and the suction hose.

For permanent indoor installations 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.

To connect the hose to the suction side [ Fig. A2 ]:

Don't use any hose quick connection system fittings on the suction side!

v A vacuum-resistant suction hose must be used, e. g. GARDENA

Suction Unit, Art. 1411 or GARDENA Bore Hole Suction Hose

Art. 1729.

A suction hose with backflow preventor must be used so that

the suction hose does not drain automatically when the pump

is switched off.

1. Screw the non-return valve

2. Connect the vacuum-resistant suction hose

non-return valve

3. For suction heights exceeding 4 m: Also secure the suction hose

(e. g. by fastening it to a wooden post).

This relieves the pump of the weight of the suction hose.

To connect the hose to the pressure side [ Fig. A3 ]:

The pump connection

(4)

is equipped with a 33.3 mm (G 1") internal

thread.

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.

Optimised use of the pump capacity is achieved by connecting

19 mm (3/4") hoses with e. g.

– GARDENA Pump Connection Set Art. 1752,

or by connecting 25 mm (1") hoses with

– GARDENA Quick Thread Coupling with male thread Art. 7115 /

Quick Coupling Hose Connector Art. 7103.

1. Screw the pump connection piece

2. Connect the pressure hose

When using other connectors, then use sealing tape

thread of the fittings.

If more than one hose /accessory is connected simultaneously, we

recommend using the

– GARDENA 2- or 4-Channel Water Distributor Art. 8193 / 8194,

GARDENA Twin-Tap Connector Art. 940

which can be screwed directly onto the pump connection piece

To pump water [ Fig. O1 / O2 ]:

CAUTION! Dry-Running of the pump!

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

before each start-up.

1. Check the pressure in the storage tank (see 4. MAINTENANCE).

2. Unscrew the screw fitting

3. Fill the pump via the filler neck

approx. 2 to 3 l of water.

4. Tighten the screw fitting

(do not use pliers).

5. Open any shut-off valves in the delivery line (accessories,

water stop, etc.).

6. Drain remaining water in pressure hose

during the suction process.

7. Connect the pump to the mains.

8. Lift and hold the delivery hose

push the On / Off switch

v If the pump does not deliver water after approx. 5 minutes,

switch off the pump (press On / Off switch

(see 6. TROUBLESHOOTING).

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 specified maximum self-priming suction height of 7 m is reached

only if the pump is filled via the filler neck up to the overflow and if, while

doing so and during the self-priming, the delivery hose

ficiently high to prevent any water escaping from the pump via the delivery

hose

4. MAINTENANCE

(a)

DANGER! Risk of injury!

Injury when the product starts accidentally.

v Disconnect the product from the mains before you maintain

(3)

the product.

To flush the pump:

After pumping chlorinated water, the pump must be flushed.

1. Pump lukewarm water (max. 35 °C), possibly adding a mild cleaning

agent (e. g. detergent) until the pumped water runs clear.

2. Remove residuals according to the waste disposal laws applicable in

your area.

To check the pressure in the storage tank [ Fig. M1 ]:

Check the pressure in the reservoir tank regularly.

The pressure in the storage tank must be approx. 1.5 bar. An air pump /

tyre inflator with pressure indicator (manometer) is required to refill the air.

1. Unscrew the protective cover

2. Open all the tapping points.

The pressure side is depressurised.

3. Place the air pump / tyre inflator on the tank valve

air until the pressure display on the air pump / tyre inflator shows

approx. 1.5 bar.

4. Screw the protective cover

5. STORAGE

To put into storage [ Fig. S1 ]:

The pump is not frost-proof!

The product must be stored away from children.

1. Disconnect the pump from the mains.

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

3. Open all the tapping points.

The pressure side is depressurised.
