Scope of supply
Your domestic water pump comes equipped a
built-in pressure switch, protection against dry
opera-tion, a non-return valve and an electric cable
with an earthing-contact type plug.
Function
The domestic water pump works automatically. The
pump automatically switches on or off depending
on the pressure set (see technical data).
If a tapping point is opened, the device sucks the
liquid to be pumped through the suction hose (1)
and lets it out at the tapping point through the
pressure hose connector.
The pump automatically switches off approx. 15
seconds after the tapping point is closed.
Thermal protection
Your domestic water pump is equipped with a
thermal protection switch, which switches the
pump off if it is in danger of overheating (see
Troubleshoot-ing).

ETTING UP AND
• Place the device onto a hard, flat surface so
that it cannot tip over and so that it will not be
near the flow of water.
• Make sure that the device is protected from
rain and any direct exposure to water.
When attaching the suction and pressure
hoses, make sure that they do not exert a
tension on the device. We recommend the use of
flexible hoses at the pump inlet and outlet. If you
have any questions, ask your retailer.
When operating the system (automatic
operation), take appropriate measures to
ensure that damage due to flooding cannot occur
if the device should malfunction.
Attaching the suction hose
Choose a hose which is long enough so that the
device will not suck in air and run dry. The hose
should be at least 30cm under the surface of the
liquid to be pumped while the pump is in operation.
• Attach the suction hose. Make sure to screw it
in tightly, but take care not to damage the
threads.
If the liquid to be pumped is deeper than 4
m, you should use a suction hose which is
larger than 1" in diametre for the best performance.
We recommend our AL-KO suction set (14), which
consists of a suction hose, strainer and non-return
valve. The suction set is available at your local
retailer's.
Before pumping sandy water, you must in-
sert a filter (13) between the suction hose
and the pump inlet or you will damage your dome-
stic water system. The filter is available at your lo-
cal retailer's.
• When laying the suction hose, make sure that it
is lower than the pump.
If the suction hose is laid so that it is higher
than the device, bubbles will become trap-
ped in the line and the pump will suck air.
Attaching the pressure hose
• Attach the pressure hose. Make sure to screw
it in tightly, but take care not to damage the
threads.
The device will not pump liquid properly if
the it is located more than 15m below the
tapping point.
