CAUTION!
Risk of injury due to hot water!
The water in the pump can heat up signi-
ficantly, during longer periods of opera-
tion (>10 min) against closed outlet side.
This hazard can occur due to:
side under compression closed
water shortage in the suction line
improper installation
faulty pressure switch
In this case:
isolate the pump from the mains
allow the pump and water to cool
down
check water level on inlet side
check lines for tightness
check installation
check pressure switch
only restart pump after rectifying the
cause of the fault
Children, or other people who are not familiar
with the operating instructions, are not allo-
wed to use the machine
STARTUP
CAUTION!
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
(1) and outlet (3). If you have any ques-
tions, ask your retailer.
CAUTION!
When operating the system (automatic
operation), take appropriate measures to
ensure that damage due to flooding can-
not occur if the system should malfunc-
tion. This can be ensured, for instance,
by installing an alarm system or a re-
serve pump.

Before putting your domestic water sys-
tem into operation, check the inlet pres-
sure at the diaphragm which can be read
out from the valve (5) on the reservoir.
Make sure that the pressure is approx.
1.5 bar and correct if required (see Che-
cking the Inlet Pressure).
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.
Attaching the suction hose
CAUTION!
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 pum-
ped while the pump is in operation.
1. Mount a non-return valve in the suction hose
to prevent the liquid from running back out of
the pump.
2. Attach the suction hose. Make sure to screw
it in tightly, but take care not to damage the
threads.
3. Before pumping sandy water, you must insert
a prefilter (17)between the suction hose and
the pump inlet or you will damage your do-
mestic water system. The filter is available at
your local retailer's.
4. When laying the suction hose, make sure that
it is lower than the system.
If the liquid to be pumped is deeper than
4 m, you should use a suction hose
which is larger than 1" in diameter for the
best performance. We recommend our
AL-KO suction set (18), which consists of
a suction hose, strainer and non-return
valve. The suction set is available at your
local retailer's.
If the suction hose is laid so that it is hig-
her than the device, bubbles will be come
trapped in the line and the pump will suck
air.
Attaching the pressure hose
1. Attach the pressure hose. Make sure to screw
it in tightly, but take care not to damage the
threads.
