be performed by children without supervision. The use of this
product by young people under the age of 16 is not recom-
mended. 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).
DANGER! Risk of injury!
v 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.

General safety warnings
Electrical safety
DANGER! Electric shock!
Risk of injury due to electric current.
v The product must be supplied through a residual current device (RCD)
having a rated residual operating current not exceeding 30 mA.
DANGER! Risk of physical injury!
Risk of injury due to electric current.
v Disconnect the product from the mains before you maintain or replace
parts. Thereby the disconnected socket must be in the visual range.
Safe operating practices
The water temperature should not exceed 35 °C.
The pump must not be used when people are in the water.
Pollution of the liquid could occur due to leakage of lubricants.
Circuit breaker
Thermal protection switch:
In the event of an overload, the pump is switched off by the built-in thermal motor
protection. After sufficient cooling of the motor, the pump is operational again.
Additional safety warnings
Electrical safety
DANGER! Cardiac arrest!
This product makes an electromagnetic field while it operates. This
field may under some conditions interfere with active or passive medical
implants. To decrease the risk of conditions that can possibly injure or
kill, we recommend persons with medical implants to speak with their
physician and the medical implant manufacturer before you operate the
product.
Cables
If extension cables are used, these must comply with the minimum cross-
sections in the table below:

DANGER! Electric shock!
Risk of injury due to electric current.
v 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.
v 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 manufac-
turer 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.
v 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 fails, the water in the
pump can heat up so that if water emerges, injuries could be caused by
the hot water.
v 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!
V 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.
v 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.
v 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.
v Use a pump pre-filter for pumping sandy liquids.
Pumping dirty water, e. g. stones, pine needles etc., can cause damage to the
pump.
v Do not pump dirty water.
2. ASSEMBLY
DANGER! Risk of injury!
Injury when the product starts accidentally.
v 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 operat-
ing conditions for the pump.
