Gardena 3500/4 Manuel D'utilisation page 9

Intended use:
The GARDENA Automatic Home & Garden Pump is intended for
private use in the home and hobby garden and is not intended to be used
for operating irrigation equipment and systems in public gardens. It can
be used for pumping rainwater, tap water and chlorinated water.
The product is not intended for continuous operation (e. g. industrial
applications, continuous circulating operation).
DANGER!
v Corrosive, easily combustible, aggressive or explosive liquids
(such as gasoline, petroleum or nitrothinner), saltwater and
food intended for consumption must not be pumped.
Pressure amplification:
If you use the pump for pressure amplification, the maximum permissible
internal pressure must not exceed 6 bar. Consequently, the maximum inlet
pressure is:
Model 1757 3500/4 – 2.0 bar
Model 1758 4000/5 – 1.5 bar
To ensure the correct inlet pressure, it is essential to use an adjus-
table pressure limiting valve.

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! Electric shock!
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.
Leaking lubricants can contaminate the pumped liquid.
Circuit breakers
Dry-running protection: If no water is pumped (undercurrent) the pump switches
off automatically.
Anti-lock protection: If the motor blocks (overcurrent), the pump switches off
automatically.
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.
DANGER! Electric shock!
The product must not be operated if there are people in the swimming
pool or garden pond.
v Make sure that the electrical plug and socket connections are fitted in
an area which cannot be flooded.
v Protect the power plug from moisture.

Connecting cable
DANGER! Electric shock!
With a cut off mains plug, moisture can get into electrical parts via the
mains cable and cause a short circuit.
v Do not cut the mains plug off (e. g. to feed through a wall).
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.
According to DIN VDE (German Electrical Engineers' Association) 0620, mains
power cables and extension cables must not have a smaller cross-section than
the rubber-sheathed cables of the designation H07RN-F.
The cable length must be at least 10 m.
Data indicated on the type plate must match technical data of the mains supply.
Disconnect the product from the mains when it is not in use.
Protect plug and power cable from heat, oil and sharp edges.
Do not use the power cable to carry or to unplug the pump.
As an additional safety device an approved safety switch can be used.
v Please ask your electrician for his advice.
Only use extension cables with earth connectors for operating this pump.
A damaged pump must not be used.
Before operating the pump look and see if there is any damage to the pump
(especially to the power cable and plug).
v In case of damage, please have the pump checked by our GARDENA
Service Centre.
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 electronic control is defective or if the water supply on the intake
side of the pump fails, any water remaining in the pump may heat up,
generating a risk of injuries caused by hot water on leakage.
v Disconnect the pump from the mains, let the water cool (approx.
10 – 15 min.) and secure the water supply on the intake side before
putting into operation again.
Do not use the product while you are tired or under the influence of drugs, alco-
hol or medication. A moment of inattention while you operate the product may
result in serious personal injury.
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.
When water flows through the pump it is no drinking water anymore.
When using the product, cover hair and do not wear scarves and other loose
items of clothing.
Make sure that no children or unauthorised persons are within reach of the pump
and the pumped medium without supervision.
In order to avoid dry-running of the pump, take care that the end of the suction
hose is always submerged into the water.
v Before each operation, fill the pump with liquid to be pumped (approx. 2 to 3 l).
The pump must be located on solid, even ground, protected from flooding.
Take care that the pump cannot fall into water.
Very fine sand can pass through the integrated filter (mesh size 0.45 mm)
and cause accelerated wear in the hydraulic parts.
v For sandy water, you should additionally use the GARDENA Pump
Preliminary Filter, art. 1730 (mesh size 0.1 mm).
The temperature of the pumped liquid must be between 2 °C and 35 °C.
Only stow the product in temperatures between 2 °C and 70 °C.
2. INSTALLATION
DANGER! Electric shock!
Risk of injury due to electric current.
v Disconnect the product from the mains before you install the
product.
Installation location [ Fig. I1 ]:
The pump must be installed in a location with sufficient venti-
lation in the area of the ventilation slots. It must be at a distance
of at least 5 cm from the walls. No dirt contamination (e. g. sand
or soil) may be sucked in through the ventilation slots.
