3. Proper use
Applications
Irrigation and watering of green areas, vegetable
beds and gardens.
Operation of lawn sprinklers.
Drawing of water (with pre-filter) from ponds,
streams, rain barrels, rainwater cisterns and
wells.
Supplying water to the house.
Transport media:
For the pumping of clear water (fresh water),
rainwater or light suds/service water.
The maximum temperature of the fluid must not
exceed +35°C if the equipment is operated
permanently.
Do not use the equipment to pump inflammable,
gassing or explosive fluids.
The pumping of aggressive liquids (acids, alkalis,
silo seepage etc.) as well as liquids with abrasive
substances (sand) must likewise be avoided.
The equipment is to be used only for its prescribed
purpose. Any other use is deemed to be a case of
misuse. The user / operator and not the
manufacturer will be liable for any damage or injuries
of any kind caused as a result of this.
Please note that our equipment has not been
designed for use in commercial, trade or industrial
applications. Our warranty will be voided if the
machine is used in commercial, trade or industrial
businesses or for equivalent purposes.

5. Before putting the equipment into
operation
5.1 Connecting the intake line
As a basic principle, we recommend the use of a
preliminary filter and a suction set with suction hose,
suction strainer 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.
The intake hose or pipe should have a minimum
diameter of 1"; a diameter of 11/4" is
recommended for suction heights exceeding
5 m.
Connect the intake valve (foot valve) with intake
cage to the intake line.
Position the intake line so that it rises from the
water withdrawal point to the equipment. Avoid
positioning the suction pipe higher than the
pump, as this would delay the escape of air
bubbles from the suction pipe 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
equipment will not run dry.
A leaking intake line will draw in air and therefore
not draw in any water.
5.2 Connecting the discharge line
The discharge line (min. 3/4") must be connected
to the 1" 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 1/2" delivery hose. The smaller
delivery hose results in a lower delivery rate.
230V ~ 50 Hz
During the priming operation, fully open any
800 W shut-off mechanisms (spray nozzles, valves,
etc.) in the pressure line so that the air can
3000 l/h
escape without obstruction.
