5. Before starting the equipment
Before you connect the equipment to the mains
supply make sure that the data on the rating plate
are identical to the mains data.
As a basic principle, we recommend the use of
a preliminary filter and a suction set with suction
hose, intake cage and non-return valve, in order
to prevent long priming periods and unnecessary
damage to the pump as a result of stones and
solid foreign bodies.
5.1 Connecting the intake line
•
Fasten the suction hose (at least approx. 19
mm (¾“) plastic hose with spiral reinforce-
ment) to the suction connection approx. 42
mm (1¼
״
) AG of the equipment either directly
or via a threaded nipple.
•
The suction hose used should be equipped
with an intake valve. If the intake valve cannot
be used, a non-return valve should be ins-
talled in the intake line.
•
Position the intake line so that it rises from
the water withdrawal point to the equipment.
Avoid positioning the intake line higher than
the pump, as this would delay the escape of
air bubbles from the intake line and impede
the priming process.
•
Install the intake and discharge lines in such
a way that they do not exert any mechanical
pressure on the equipment.
•
The intake valve should be low enough in the
water to ensure that if the water level falls, the
unit will not run dry.
•
A leaking intake line will draw in air and there-
fore not draw in any water.
•
Prevent the intake of foreign bodies (sand,
etc.). If necessary, install a coarse filter for
this purpose.
5.2 Connecting the discharge line
•
The discharge line (min. 19 mm (¾“)) must
be connected to the approx. 33.3 mm (1
״
) IG
female thread discharge line connector of the
equipment either directly or with the aid of a
threaded nipple.
•
With the right couplings it is also possible, of
course, to use a 13 mm (½ “) delivery hose.
The smaller delivery hose results in a lower
delivery rate.
•
During the priming operation, fully open any
shut-off mechanisms (spray nozzles, valves,
etc.) in the pressure line so that the air can
escape without obstruction.
5.3 Electrical connections
•
Connect the appliance to a 220-240 V ~ 50
Hz socket-outlet with earthing contact. Mini-
mum fuse 10 ampere.
•
A built-in thermostat protects the motor from
overloading and blocking. The pump is swit-
ched off automatically by the thermostat if
overheating occurs and is switched on again
automatically after cooling.
