DANGER!
Risk of injury!
The pump must not be used for the delivery of salt water, muddy water, corro-
sive, easily inflammable or explosive liquids (e. g. petrol, paraffin, thinners), oil,
heating oil or foodstuffs.
1.3.1.2 Pressure amplification:
The inlet pressure must be protected by an adjustable pressure relief valve. When
the pump is used for pressure amplification, the maximum permissible internal
pressure must not exceed 6 bar. The maximum inlet pressure is therefore:
GARDENA Garden pump 4100 Art. 9050
v
Max. 2.4 bar
GARDENA Garden pump 4200 Art. 9054
v
Max. 2.1 bar
GARDENA Garden pump 4300 Art. 9056
v
Max. 1.7 bar
1.3.2 Additional electrical safety warnings
DANGER!
Risk of cardiac arrest!
This product generates an electromagnetic field while it operates. This electro-
magnetic field may affect the functionality of active or passive medical implants
(e. g. pacemakers), which may result in serious injury or death.
v
Consult your doctor and the manufacturer of your implant before using this
product.
v
After using the product, disconnect the mains plug from the mains socket.
The pump must be installed in a stable and flood-proof location and protected
against falling into the water. 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
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.
v
Protect the mains plug and the mains power cable from heat, oil and sharp
edges.
v
Do not use the power cable for carrying the pump or for unplugging.
v
Place the pump in a flood-proof location.
v
Please regularly check the connecting line.
v
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.
v
In the event of damage, have the pump checked by GARDENA Service.
Electrical changes are only conducted by an electrical specialist.
v
Before filling, dismantling, maintenance disconnect the mains.
v
When using our pumps with a generator, the warnings of the generator
manufacturer must be observed.
1.3.2.1 Cables:
If extension cables are used, these must comply with the minimum cross-sections
in the table below:
Voltage
Cable length
Cross section
230 – 240 V / 50 Hz
Up to 20 m
1.5 mm²
230 – 240 V / 50 Hz
20 – 50 m
2.5 mm²
1.3.3 Additional personal safety warnings
DANGER!
Risk of suffocation!
Small parts can be easily swallowed.
v
Keep toddlers away when you assemble the product.
DANGER!
Risk of injury from hot water!
Pumped water is under pressure and when it hits the body or eyes
directly can cause injury.
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
Let the pump operate for max. 5 minutes against the closed pressure
side or with missing water supply.
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 and let the water cool.
v
Do not open any caps and screw connections when the water is hot.
v
Before restarting, secure the water supply on the suction side and fill
the pump completely with water.
If hoses or pipes are exposed to the sun, they can become very hot.
Do not use the product with loose hair.
When connecting the pump to the water supply system, the country-specific san-
itary regulations must be observed to prevent water not of drinking water quality
being drawn back in.
v
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 with water up to the overflow (min. 1.1 l)!
v
When filling the pump with water, make sure that no hoses or consumers are
connected to the pump and that the pump is generally in a horizontal position.
v
Make sure that the hoses are laid without kinks.
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.
The minimum flow rate is 90 l/h (1.5 l/min). Connection devices with a lower flow
rate must not be operated.
2. ASSEMBLY
DANGER!
Risk of injury!
Risk of injury due to accidental starting.
v
Unplug the plug of the mains cable from the mains socket.
2.1 Installation site:
• When installing below the water level, a shut-off device must be
installed to prevent unwanted water loss.
• The installation site must be horizontal, solid and dry and allow the
pump to stand securely.
• It must be at a distance of at least 2 m from the water.
• The pump must be installed in a flood-proof location with sufficient
ventilation in the area of the ventilation slots.
• The distance to the walls must be at least 5 cm.
• Dirt (e. g. sand or soil) must not be sucked in through the ventilation
slots.
2.2 To connect the hose to the suction side [ Fig. A6 ]:
The connector on the suction side
(1)
is equipped with a 33.3 mm (G 1")
external thread.
The connection piece on the suction side may only be tightened
by hand [ Fig. A2 ].
In order to reduce the suction time, it is advisable to use a suction hose
with backflow preventer avoiding automatic draining of the suction hose
when the pump has been switched off [ Fig. A3 ].
Sucking in air in the suction system can lead to functional failure and
increased noise generation.
v
Connect the suction system carefully.
v
Check the gasket regularly and replace it if necessary.
Don’t use any hose quick connection system fittings on the suction side.
A vacuum-resistant suction hose must be used on the suction
side:
• e. g. the GARDENA Suction Unit Art. 1411 / 1412 / 1418
• or the GARDENA Bore Hole Suction Hose Art. 1729.
• Connect suction hoses
(2)
without threaded connection via a suction
hose connection piece (e. g. Art. 1723 / 1724) to the connection of the
suction side and screw it airtight.
2.2.1 There are 2 types of connection systems:
Intended for flat gasket:
No thread sealing tape is required.
v
Make sure that the flat gasket
ß
G
is inserted in the suction hose
connection piece and is undamaged.
Intended for thread sealing tape (Teflon):
No flat gasket is required.
An unsuitable sealing system can lead to leaks.
v
Use the sealing system intended for this purpose.
