6 ASSEMBLY

 During the installation of the water pump, the power supply to the water pump must be

switched off.

 During installation of the equipment, it is necessary to keep it under dry and well-ventilated

conditions, at an ambient temperature below 40°C.

 If the required pumping water is excessive due to your own action, resulting in flooding of

the irrigation site, a number of protective measures may be taken (e.g. installation of a
device for discharging the excess water, an alarm, standby pump, water container, etc.).
However, our company is not responsible for any losses thus caused.

 Before use, the water pump should be inspected for safety to ensure that there is no

damage to the power cable or the plug.

6.1

Electrical connection

 The electrician responsible for installation must check to ensure that the electrical

connection is in accordance with the standard, including the earth terminal.

 It is necessary to check the rated current of the electric contact with protective switch - this

must be = 30mA (in accordance with DIN VDE 0100T739).

6.2

Earth

The water pump must be well earthed. Short-circuiting will render the relevant articles of the
guarantee invalid. If it is necessary to increase the length of the original cable, a cable with the
same section as the original cable must be used.

7 OPERATION

The pumps are not self-priming pumps. This means that the suction hose should first of all be
fitted with:
1

Non-return valve with filter; this ensures that, after disconnecting the pump, the hose
and the pump do not run dry. This part of the hose is suspended in the water to be
pumped away.

2

Hose with coupling nut; this end of the hose is attached to the front of the pump.

3

Both accessories should be securely screwed on to the hose using the hose clip
supplied.

Before fastening the hose to the pump, it is best to fill it with water first. After this you can
screw the three-way cock or another 1" connector to the outlet on the pump; this is on the top
of the pump.
Then you should loosen the small screw cap on top of the pump housing and fill the pump
housing with water through the opening; then re-seal it.
If the pump housing and the hose have both now been filled with water, you can switch on the
pump using the on/off switch. The pump now immediately begins to pump water (in the case
of the auto version, the pressure tank is first filled and it takes a few seconds before water
comes out of the connected hose).
If the pump is subsequently switched off again, water remains in the pump housing and the
hose which means that when the pump is next switched on it will pump water immediately.
If no non-return valve is fitted or if the seal between the valve and the hose is not working
properly (hose clip!) the whole unit may run dry again and must be re-filled to get the pump to
work properly.
