1.4 Additional safety warnings
1.4.1. Intended use
This product can be used by children aged from eight years and above and per-
sons with reduced physical, sensory or mental capabilities or without experience
and knowledge provided they are supervised or have been instructed on using the
product safely and understand the hazards involved. Children must not play with
the product. Cleaning and user maintenance must not be performed by children
without supervision unless they are eight years of age or older and are supervised.
The use of this product by young people under the age of 16 is not recommended.
The GARDENA pressure tank unit is intended for pumping ground and rainwa-
ter, tap water and chlorinated water in private gardens and allotments.
The product is not intended for commercial use.
The product is not intended for permanent operation.
1.4.2. Transport fluids
The GARDENA pressure tank unit may only be used to transport water.
DANGER!
Risk of injury
Æ Do not convey salt water, dirty water, corrosive, highly flammable or
explosive substances (for example petrol, petroleum, nitro thinners),
oils, fuel oil or food.
1.4.3. Additional electrical safety warnings:
DANGER!
Risk of cardiac arrest
This product generates an electromagnetic field while it operates. This
electromagnetic field may affect the functionality of active or passive
medical implants (e.g. pacemakers), which may result in serious injury
or death.
Æ Consult your doctor and the manufacturer of your implant before
using this product.
Æ After using the product, disconnect the mains plug from the mains
socket.
Æ Place the pump in a stable and flood-proof position so that it cannot fall into
the water.
Æ Set the pump at a safe distance (min. 2 m) from the transport fluid.
An approved personal safety switch can be used as an additional safety feature for
the residual-current device (RCD).
Æ Ask a qualified electrician about this.
The information on the rating plate must match the mains data.
Æ Unplug the pump before anyone enters a swimming pool connected to it.
If the mains connection cable of this machine is damaged, it must be replaced by
the manufacturer or its after sales service team or a similarly qualified person to
avoid danger.
Æ Protect the mains plug and mains connection cable from heat, oil or sharp edges.
Æ Do not carry the pump by the cable or use the cable to remove the plug from the
wall socket.
Æ Install the pressure tank unit in a flood-proof location.
Æ Do not expose the pump to rain or use the pump in a wet or humid environment.
Æ Check the connection cable at regular intervals.
Æ Always conduct a visual inspection of the pump (especially the mains connection
cable and mains plug) before use.
A damaged pump must not be used.
Æ It is essential to have the pump checked by GARDENA Service if it is damaged.
Electrical modifications may only be carried out by a qualified electrician.
Æ Disconnect the pump from the mains before filling, removal or maintenance.
Æ Take heed of the generator manufacturer's warnings when using our pumps with
a generator.
1.4.4. Cables
When using extension cables, they must comply with the minimum cross-sections
in the following table:
Voltage Cable length
230–240 V/50 Hz Up to 20 m
230–240 V/50 Hz 20–50 m
1.4.5. Additional personal safety warnings
DANGER!
Risk of suffocation
Small parts can easily be swallowed. There is a choking hazard for
small children due to the polybag.
Æ Keep small children away whilst you install the product.
10
The pumped water is pressurised and can cause injury if it directly
strikes the body or eyes.
Æ Disconnect the pump from the mains and let the water cool down.
Æ Do not open caps or fittings when the water is hot.
Æ Before restarting, ensure the intake water supply is correct and fill the pump com-
pletely with water.
If hoses or pipes are exposed to the sun, they can become very hot.
Æ Do not use the product with untied hair.
Æ Do not connect the pump to the drinking water supply.
Æ To prevent the pump from running dry, make sure that the suction hose end is
always in the transport medium.
Æ Fill the pump up to the overflow (min. 2.2 l) with water before starting it each time.
Æ When filling the pump with water, make sure that no hoses or consumers are
connected to the pump and that the pump is generally horizontal.
Æ Make sure that the hoses are not kinked.
Sand and other abrasive materials cause faster wear and reduced pump
performance.
Æ If water contains sand, use a pump pre-filter.
Pumping contaminated water, for example containing stones, pine needles etc.,
can damage the pump.
Æ Do not pump heavily contaminated water.
2. FUNCTION
2.1 How the pressure tank unit works
After being filled, the pump unit draws in water from a depth of up to 8 m
and pumps it into the reservoir. This stores the water, which is pressurised
by means of a pre-set air pressure and a separating membrane.
The pump unit starts when water is removed and the intended initial pres-
sure is reached (see „8. Technical data") and stops the filling process
again when the cut-off pressure is reached. This means that small quantities
of water can be pumped out of the tank in an energy-efficient manner. At
high flow rates, such as for irrigation, however, the pressure fluctuations
between the on and off pressure are clearly perceptible.
3. INSTALLATION
Risk of injury due to unintentional startup.
Æ Disconnect the power cable plug from the mains socket.
3.1 Installation location
• If installed below water level, a shut-off device must be installed to pre-
vent unwanted water loss.
• The installation location must be horizontal, firm and dry and provide the
pressure tank unit with firm support.
• It must be located at least 2 m away from open water.
• The pressure tank unit must be installed in a dry and flood-proof place
with sufficient ventilation around the ventilation slots.
• It must be at least 5 cm away from walls.
• No dirt (for example sand or earth) may be sucked in through the venti-
lation grille.
3.1.1 Installing the pressure tank unit [Fig. A6/A7/A8]
• The pressure tank unit can be screwed to a firm surface. See Fig. A7
Cross-section
below for a sketch of the hole spacing. We suggest that four screws
1.5 mm²
7.5 x 45 (concrete screw) or 8 x 45 (wood screw) are used to install
it on the floor.
2.5 mm²
• Ensure that the surface does not suffer from vibrations. Hex head screws
are recommended.
• Set up the pressure tank unit so that you can place a receptacle of the
appropriate size for emptying the pump under the drain screw (15). To
prevent water leaking onto the floor during the emptying process and
to allow the pump unit to be emptied fully, it must be possible to tilt the
pressure tank unit forwards by approx. 80° towards the drain screw (15).
• Position the pressure tank unit so that the mains switch is easily
accessible.
