be performed by children without supervision. The use of this product by young people under the age of 16 is not recommended. Never operate the product when you are tired, ill or under the influence of alcohol, drugs or medicine.

Intended use:

The GARDENA Pressure Tank Unit is intended for pumping ground water and rain water, tap water and water containing chlorine in private domestic gardens and allotments.

In the case of open consumers (e.g. water taps), pressure fluctuations may occur between the switch-on and switch-off ranges at certain flow rates.

Liquids to be pumped:

The GARDENA Pressure Tank Unit must only be used to pump water. When the pump is used for pressure boosting, the maximum permissible internal pressure of 6 bar (on the delivery side) must not be exceeded. The increased delivery pressure and the pump pressure have to be added together.

- Example: Pressure at the tap = 1.9 bar, max. pressure of the Pressure Tank Unit = 4.1 bar, total pressure = 6.0 bar.

The product is not intended for long term use (continuous circulation operation).

GER! Risk of injury!

→ The pump must not be used for the delivery of salt water, muddy water, corrosive, easily inflammable or explosive liquids (e.g. petrol, paraffin, thinners), oil, heating oil or foodstuffs.

230 – 240 V / 50 Hz Up to 20 m 1.5 mm	^2
230 – 240 V / 50 Hz 20 – 50 m 2.5 mm	^2

DANGER! Electric shock!

of injury due to electric current.

→ Disconnect the product from the mains before you put into storage, maintain or troubleshoot.

The pump must be located on solid, even ground, protected from flooding. Take care that the pump cannot fall into water. Position the pump at a safe distance (min. 2 m) from the liquid to be pumped. As an additional safety device an authorised safety switch can be used.

→ Please ask your electrician for his advice.

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

Protect the mains plug and the mains power cable from heat, oil and sharp edges.

Do not use the power cable for carrying the pump or for unplugging.

The pressure switch must not be opened. If the pressure switch is defective, contact GARDENA Service.

Protect the pump from rain. Don't use the pump in wet or moist areas.

Please regularly check the connecting line.

Before using, always subject the pump (especially the power cables and the power connections) to a visual inspection.

A pump which is damaged must not be used. In the event of damage, have the pump checked by GARDENA Service.

When using our pumps with a generator, the warnings of the generator manufacturer must be observed.

Personal safety

DANGER! Risk of suffocation!

Small parts can be easily swallowed. There is also a risk that the poly-bag can suffocate toddlers. Keep toddlers away when you assemble the product.

DANGER! Risk of injury due to hot water!

If the pump is operated for prolonged periods of time (> 5 min.) with the delivery side closed, the water in the pump may heat up so that there is a risk of scalding yourself with hot water.

→ The pump should not run against the closed delivery side for more than 5 minutes.

If the water supply on the intake side of the pump falls, the water in the pump can heat up so that if water emerges, injuries could be caused by the hot water.

→ Disconnect the pump from the mains via the main circuit breaker, let the water cool and secure the suction-side water supply before putting into operation again.

DANGER! Hearing damage due to bang!

→ The tank must not be opened.

When connecting the pump to the water supply system, the country-specific sanitary regulations must be observed to prevent water not of drinking water quality being drawn back in.

→ Please consult a specialist for sanitary installations.

In order to avoid dry-running of the pump, take care that the end of the suction hose is always submerged into the liquid.

→ Before each operation, fill the pump to overflowing with approx. 2 to 3 l of the liquid to be pumped!

Sand and other abrasive substances cause increased wear and reduce the pump's output.

→ Use a pump pre-filter for pumping sandy liquids.

Pumping dirty water, e. g. stones, pine needles etc., can cause damage to the pump.

→ Do not pump dirty water.

2. ASSEMBLY

ER! Risk of injury!

when the product starts accidentally.

→ Disconnect the product from the mains before you assemble the product.

To set up the pump:

The site must be firm and solid in order to ensure safe and sturdy operating conditions for the pump.

→ 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 sufficient 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 pressure tank unit from slipping.

→ The Pressure Tank Unit can be screwed with all 4 feet ⑪ onto a solid surface ⑫ (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 ⑨ to allow the unit or system to be 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!

→ A vacuum-resistant suction hose must be used, e. g. GARDENA SuctionUnit, 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 into the pump connection ① with the O-ring ⑩ in the direction of the pump up to the stop ⑧ until the stop ⑧ touches the pump connection ①.
2. Connect the vacuum-resistant suction hose ③ airtight to the pump non-return valve ②.
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 ① into the connector on the delivery side ④.
2. Connect the pressure hose ⑤ to the pump connection piece ⑥.

When using other connectors, then use sealing tape Ⓟ on the external 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 ⓒ.

3. OPERATION

→ Disconnect the product from the mains before you connect, adjust or transport the product.

To pump water [Fig. 01/02]:

TION! Dry-Running of the pump!

→ 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 ⑥ of the filler neck ⑦ by hand.
3. Fill the pump via the filler neck ① to overflowing with approx. 2 to 3 l of water.
4. Tighten the screw fitting ⑥ of the filler neck ⑦ by hand (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 ⑤ so that air can escape during the suction process.

7. Connect the pump to the mains.

8. Lift and hold the delivery hose ⑨ at least 1 m vertically above the pump, push the On/Off switch⑧ and wait until the pump has primed.

→ 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 automatically. 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 ⑤ is held up sufficiently high to prevent any water escaping from the pump via the delivery hose ⑤.

4. MAINTENANCE

IGER! Risk of injury!

By when the product starts accidentally.

→ Disconnect the product from the mains before you maintain 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 ⑬.
2. Open all the tapping points. The pressure side is depressurised.
3. Place the air pump / tyre inflator on the tank valve ^⑭ and refill with air until the pressure display on the air pump / tyre inflator shows approx. 1.5 bar.
4. Screw the protective cover ⑬ close again.

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.

4. Open the screw fitting ⑥ of the filler neck ⑦ and the water drain screw ⑨. The pump drains.

5. Store the pump in a dry, enclosed and 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!

→ Dispose of the product through or via your municipal recycling collection centre.

6. TROUBLESHOOTING

GER! Risk of injury!

when the product starts accidentally.

→ Disconnect the product from the mains before you trouble-shoot the product.

To loosen the impeller [Fig. T1]:

An impeller blocked by dirt can be freed again.

→ Turn shaft of the impeller ⑩ with a screwdriver. This will loosen the stuck impeller.

To clean the filter [Fig. T2]:

If the pump does not start or stops suddenly during operation, this may be due to a clogged filter.

1. Loosen the screw connection ⑮.
2. Unscrew the filter ⑯.
3. Clean the filter ⑯ under running water.
4. Assemble the filter ⑯ in reverse order.

Problem Possible Cause Remedy

Pump is running, but the suction action doesn't take place	Leaky or damaged suction hose.	→ Check suction line for damage and seal it so it isairtight.
	The pump was not filled with water.	→ Fill the pump (see 3. OPERATION).
	The liquid escapes over the hose which is connected to the delivery side during the suctionaction.	→ 1. Fill the pump again (see 3. OPERATION).2. When starting operation hold the pressure hose approx. 1 m vertically above the pump, until the suction action has taken place.
	Absolutely vacuum-resistant connection is achieved by using GARDENA Suction Hoses (see 8. ACCESSORIES).
	Leaky screw fitting at the filler neck.	→ Check seal (replace if necessary) and tighten connection securely (do not use pliers).
	Air cannot escape, since delivery side is closed or remaining water is in the pressurehose.	→ Open shut-off valves (e. g. nozzle) in the delivery line, empty the delivery hose or disconnect it from the pump during priming.
	The waiting time wasn't observed.	→ Switch on the pump and wait up to 5 min.
	Suction filter or backflow preventer in the suction hose clogged.	→ Clean the filter or the back flow preventer.
	Too high suction height. → Reduce suction height.
	In case of any other difficulties concerning the suction action, use GARDENA Suction Hoses with Backflow Preventer (see 8. ACCESSORIES) and fill in the liquid to be pumped over the filler neck before operation.
Pump does not start, or stops suddenly during operation	Thermal switch has turned the pump off because of over-heating.	→ Clean the filter.Observe the max. media temperature (35 °C).
	No power supply to the pump. → Check fuses and electrical plug connections.

Problem Possible Cause Remedy

Pump does not start, or stops suddenly during operation	RCD has triggered (residual current).	Disconnect the pump and contact the GARDENA Service.
	Pump is not switched on. Push the On / Off switch to On.
Pump is running but the delivery drops suddenly	Suction hose end is not in water.	Submerge the end of the suction hose deeper in the water.
	Suction filter or backflow preventerclogged.	Clean the suction filter or back-flow preventer.
	Leaks at suction side. Eliminate leak.
	Impeller blocked.	Release impeller.
Noise development in the hydraulic area	In the case of strong flows (e.g. open hose end, without connecting device), noise may result in the hydraulic part of the pump. This is harmless and does not lead to damage of the pump. The noise can be removed by lightly changing the flow (e.g. light opening / closing of a connecting device).
Pump switches on and off too often	Tank membrane is damaged.	Let the tank membrane be replaced by the GARDENA Service.
	Pressure in the tank is too low.	Refill the air in the storage tank.
	Leakage on the pressure side. Eliminate leaks on the pressureside.

NOTE: For any other malfunctions please contact the GARDENA service department. Repairs must only be done by GARDENA service departments or specialist dealers approved by GARDENA.
