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 a hose clip.
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 25mm (1") connector to the outlet on the pump; this is
on the top of the pump.
Then you should fill the pump housing with water through the build-in filter; 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.
7.1 Pressure hose
The pressure hose is used for conveying the water from the pump to the water consumption
point (e.g. tap, etc.). In order to minimize the friction loss caused by the water pressure, we
recommend that you use a pressure hose with a minimum diameter of 20mm (3/4").
▪ When the garden pump is working, the water outlet (e.g. tap or water sprinkling outlet)
must be open so as to discharge the air from the hose. If the water outlet is closed, the
pump may be damaged due to overheating of the pump after working for more than 5
minutes.
▪ Freezing of the pump or placing it in a frosty space in the winter must be avoided.
▪ Sand and stones in the water taken in can rapidly wear the pump and reduce its effective
capacity. It is therefore necessary to install a filter.
▪ This water pump is not suitable for long-term operation, e.g. in industrial or mining
enterprises or for a water recycling system.
7.2 Safety requirements
▪ The power supply must comply with the specifications displayed on the product. Refer to
the instructions of your local energy supplier if necessary for connecting conditions. If the
pump or the power cable do not comply, do not connect the pump!
▪ Never carry the pump by the cable.
▪ Never remove the plug and never shorten the cable. If you do, you will invalidate your
guarantee. Keep the connection (plug and socket) dry.
▪ The pump is not suitable for use in swimming pools and lakes or other situations where
persons could come into physical contact with the water, and must therefore not be used
for this purpose.
▪ Always disconnect the pump from the power supply when cleaning it or carrying out
maintenance to the pond. This pump is suitable for pumping water with a minimum
temperature of 4 °C and a maximum temperature of 35 °C.
▪ The pump must not run dry, as this will cause irreparable damage.
▪ Always disconnect the pump from the mains supply before cleaning or maintenance.
▪ Clean the chambers from time to time, rinsing them with clean water, to ensure they are
not clogged with dirt.
