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.
➔
Position the pump at a safe distance (min. 2 m) from the liquid
to be pumped.
Connecting hose
Don’t use any hose connection system fittings on the suction side!
to suction side:
A vacuum-resistant suction hose must be used
•
e.g. GARDENA Suction Unit,
art. no. 1411
.
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 airtight onto the con-
nector
on the suction side of the pump
.
2. For suction heights exceeding 4 m also secure the suction
hose
(e.g. by fastening it to a wooden post).
This relieves the pump of the weight of the suction hose.
Connection hose
The two pumps 3000/4 Jet and 3500/4 Jet are equipped with
to delivery side:
2 connections
/
4a
on the pressure side. The rear pump
connection
4a
is closed with a cap that can be unscrewed to
connect 2 hoses.
The pump connections
/
4a
are equipped with a 33.3 mm (G 1“)
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.
Best results regarding the delivery capacity of the pump are
achieved when connecting 19 mm (3/4”) hoses in conjunction
with e.g.
• GARDENA Pump Connection Set,
art. no. 1752
,
or when using 25 mm (1”) hoses with fittings available from your
sanitary dealer.
➔
Connect the pressure hose to the connector
on the delivery
side
.
With parallel connection of more than 2 (3000/3 Jet more than 1)
hoses/watering accessories we recommend the use of
• GARDENA Twin-Tap Connectors or Four-Channel Water
Distributors
art. no. 1210/1194
,
which can be screwed directly onto the connection on the
pressure side
.
