2. Safety Instructions

DANGER! Electric shock!

Risk of injury due to electric shock.

v Always unplug your Garden Pump before fil-

ling, after operation, when trouble-shooting

and before carrying out any maintenance work.

CAUTION:

Keep cable plug dry!

RISK OF INJURY!

Hot water – risk of scalding!

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.

Location

Caution: Pursuant to DIN VDE 0100-702 and

0100-738 use of the pump nearby swimming pools

and garden ponds and other similar places is only

permissible if the pump is operated via a residual-

current device (FI switch) with a residual current

rating of ≤ 30 mA. The pump must not be operated

when there are persons in the swimming pool or

garden pond.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.

When connecting the pump to the water supply

system, the country-specific sanitary regulations

must be observed to prevent water not of drink-

ing water quality being drawn back in.

v Please consult a specialist for sanitary

installations.

Extension cables

Data indicated on the type plate must match

technical data of the mains supply.

Pursuant to DIN VDE 0620, power cable as well

as extension cables must not have a smaller

diameter than rubber sheathed cables described

with letter symbols H05 RNF.

v Don't use the power cable for carrying the

pump or for plugging off.

In Austria

In Austria, the electrical connections must be

made according to ÖVE-EM 42, T2 (2000) /

1979 § 22 based on § 2022. Pursuant to this

regulation it's imperative to operate pumps for

swimming pools and garden ponds exclusively

via an isolating transformer.

v Please ask your electrician.

In Switzerland

In Switzerland mobile appliances which are

used outdoors, must be connected via a residual-

current device.

Visual check

v Before operating the pump, first make a visual

cheek, if there is any damage of the pump

(esp. regarding power cable and plug).

A damaged pump must not be used.

v In case of damage, please have the pump

checked by our GARDENA Service Centre or

by an authorised electrician.

Note

v Protect the pump from rain. Don't use the

pump in wet or moist area.

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 over-

flowing with approx. 2 to 3 l of the liquid to be

pumped!

Sand and other abrasive substances in the liquid

cause in-creased wear and reduce the pump's

output.

v Use a pump preliminary 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).

Watering accessories with lower rate must not

be operated.

3. Initial Operation

Setting up your Garden Pump:

The site must be firm and solid in order to ensure safe and sturdy

operating conditions for the pump.

v Position the pump at a safe distance (min. 2 m) from the liquid

to be pumped.

The pump must be installed in a location with low air humidity

and sufficient ventilation in the area of the ventilation slots.

It must be at a distance of at least 5 cm from the walls.

No dirtcontamination (e.g. sand or earth) may be sucked in

through theventilation slots.

Connecting hose to

Don't use any hose connection system fittings on the

suction side:

suction side! A vacuum-resistant suction hose must be used,

e. g. GARDENA Suction Unit (suction hose Art. 1721,

suction hose fitting Art. 1724 and suction filter with backflow

Art. 1727.

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 is stopped.

1. Screw a vacuum-resistant suction hose

connector on the suction side of the pump

2. For suction heights exceeding 4 m also secure the suction

hose

This relieves the pump of the weight of the suction hose.

Connection hose to

The 3500/4 pump has 2 connections

delivery side:

The pump connection not in use has to be closed by the cap

which can be unscrewed for connecting 2 hoses.

The pump connections

thread which can be used to connect 13 mm (1/2"), 16 mm (5/8")

or 19 mm (3/4") hoses via the GARDENA hose connection system.

Optimised use of the pump capacity is achieved by connecting

19 mm (3/4") hoses with e.g. GARDENA Pump Connection Set

Art. 1752, or by connecting 25 mm (1") hoses with GARDENA

Quick Thread Coupling with female thread Art. 7109 / Quick

Coupling Hose Connector Art. 7103.

v Connect the pressure hose

side

If more than 2 (3000/4 more than 1) hoses / accessories are

connected simultaneously, we recommend using the

GARDENA 2- or 4-Channel Water Distributor Art. 8193/8194,

GARDENA Twin-Tap Connector Art. 940 which can be screwed

directly onto the connection on the delivery side
