6. 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 switched
off automatically by the thermostat if overheating
occurs and is switched on again automatically
after cooling.
7. Suction line
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.
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.
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.
Fasten the suction and delivery lines so that they
exert no mechanical pressure on the pump.
The suction valve should lie deep enough in the
water to rule out any dry running of the pump
when the water level drops.
A leak in the suction line will draw in air and
obstruct priming.
Avoid drawing in foreign bodies (sand, etc.); fit a
pre-filter if necessary.
8. Connecting the delivery line
Attach the delivery line (min. 3/4“) either directly
to the pump’s pressure line connection (1“
female thread) or via a threaded nipple.
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.
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.
