4. Operating instructions
As a basic rule we recommend using a pre-filter and
a suction set consisting of a suction hose, a suction
basket and a non-return valve in order to prevent
lengthy re-priming times and unnecessary damage to
the pump by stones and solid foreign bodies.

6. Electrical connections
앬
Connect the appliance to a 230 V ~ 50 Hz
socket-outlet with earthing contact. Minimum fuse
10 ampere.
앬
A built-in thermostat protects the motor from
overloading and blocking. The pump is switched
off automatically by the thermostat if overheating
occurs and is switched on again automatically
after cooling.
7. Suction line
앬
No matter whether the suction line is a hose or
tube, it should have a minimum diameter of 1
inch. A diameter of 1 1/4“ is recommended for
suction heads of over 5 m.
앬
Fit the intake valve (foot valve) together with the
intake basket to the suction line. If this is not
possible you will have to install a non-return
valve in the suction line.
앬
Lay the suction line at an ascending gradient
from the water source to the pump. Be sure not
to take the suction line higher then the pump or
the priming operation will be delayed and
obstructed by air bubbles in the line.
앬
Fasten the suction and delivery lines so that they
exert no mechanical pressure on the pump.
앬
The suction valve should lie deep enough in the
water to rule out any dry running of the pump
when the water level drops.
앬
A leak in the suction line will draw in air and
obstruct priming.
앬
Avoid drawing in foreign bodies (sand, etc.); fit a
pre-filter if necessary.
8. Connecting the delivery line
앬
Attach the delivery line (min. 3/4“) either directly
to the pumpʼs pressure line connection (1“ female
thread) or via a threaded nipple.
앬
With the right couplings it is also possible, of
course, to use a 1/2“ delivery hose. The smaller
delivery hose results in a lower delivery rate.
앬
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.
9. Starting up
앬
Set up the house waterworks on a firm, level and
horizontal surface.
앬
Fill the pump case with water through the
delivery line connection. Priming is accelerated if
the suction line is full.
앬
Tightly connect the suction and delivery lines.
앬
Close the delivery line.
앬
Connect up the pump - priming at max. suction
head can take up to 5 minutes.
앬
The pump switches off when the switch-off
pressure (3 bar) is reached.
앬
