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. 33.3
mm (R1 female thread) of the equipment eit-
her 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

GB
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 33.3 mm (R1IG) female
thread discharge line connector of the equip-
ment either directly or with the aid of a threa-
ded 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 230 V ~ 50 Hz
socket-outlet with earthing contact. Minimum
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.
6. Operation
•
Install the equipment on a solid and level
surface.
•
Fill the pump housing with water via the water
filler screw (5). Filling the intake line will acce-
lerate the priming process.
•
All the shut-off devices in the discharge line
(spray nozzle, valves etc.) must be fully ope-
ned during intake in order to permit all air to
escape from the intake line.
•
Connect the mains cable. The priming pro-
cess starts automatically. – priming can take
up to 5 minutes at maximum suction height.
•
The equipment will shut down when the cut-
out pressure of 3 bar is reached.
•
After a loss of pressure due to water con-
sumption the equipment will cut in again auto-
matically (cut-in pressure approx. 1.5 bar).
