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 to 35 °C.
Only stow the product in temperatures between 2 °C to 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.
Set up the pump so that it is prevented from slipping and that an appro-
priately large collecting vessel for draining the pump or the system can be
(1)
placed under the drain screw
.
Install the pump at a safe distance (min. 2 m) from the pumping medium.
If possible, install the pump higher than the surface of the water to be
pumped. If this is not possible, install a vacuum-resistant shut-off device
between the pump and the suction hose to allow the integrated filter to
be cleaned.
If the system is permanently installed, appropriate shut-off devices must
be installed on the input and output sides. Important for maintenance and
cleaning work on the pump or for shutdown, for example.
Connections:
CAUTION!
The GARDENA connection pieces on the intake and deli-
very sides may only be tightened by hand. Check whether the
seal ring is present and undamaged before screwing the suction
hose onto the suction inlet. When using metal connections,
damage could occur on the connection thread due to inapprop-
riate assembly. Therefore, screw on the connection fittings
with the upmost care. Use sealing tape only for sealing metallic
connection fittings.
Suction side:
Do not use modular water hose components on the suction side!
A vacuum-tight suction hose must be used e.g.:
– GARDENA Suction Hose Art. 1411 / 1418
– GARDENA Bore Hole Suction Hose Art. 1729
– GARDENA Suction Hose sold by the metre with
GARDENA Hose Clamp Art. 7192 / 7191.
If very fine dirt is present, we recommend the use of a GARDENA Pump
preliminary filter Art. 1730 / 1731 in addition to the integrated filter.
To reduce the pump repriming time, we recommend to use a suction
hose with backflow preventer, which prevents the suction hose emptying
automatically when the Automatic Home & Garden Pump is switched off.
Important for fixed installation:
For greater suction heads, use a suction hose with a small diameter (3/4").
Pressure side:
A pressure-resistant hose must be used on the pressure side, e. g.:
– GARDENA Garden Hose (3/4") Art. 18113 with
GARDENA Connection Set Art. 1752.
Important for fixed installation:
If the product is permanently installed in an enclosed space, only flexible
hoses (e.g. reinforced hoses) may be used for connecting the service
water supply, rather than rigid piping. Flexible hoses will reduce the noise
level and prevent damage caused by pressure surges. Install fixed pipes
at an upward gradient on the first 2 m only. To avoid damage to the
thread, ensure careful and accurate installation when using metal
connections.
To connect the suction hose [ Fig. I2 ]:
1. Screw the suction hose fitting
it by hand.
(2)
2. Slide the suction hose
onto the suction hose fitting
it e.g. with a GARDENA Hose Clamp Art. 7192 / 7191.
(3)
onto the suction inlet
(4)
and tighten
(3)
and secure
