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

GARDENA Garden pump 4200 Art. 9054

GARDENA Garden pump 4300 Art. 9056

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

230 – 240 V / 50 Hz

Up to 20 m

230 – 240 V / 50 Hz

20 – 50 m

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 Max. 2.4 bar

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 Max. 2.1 bar

v Do not pump dirty water.

v Max. 1.7 bar

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

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

external thread.

The connection piece on the suction side may only be tightened

by hand [ Fig. A2 ].

Cross section

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

1.5 mm²

when the pump has been switched off [ Fig. A3 ].

2.5 mm²

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

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

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.
