Safety instructions
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
Always ensure stability when working.
STARTUP
Place the garden pump onto a hard, flat sur-
face so that it cannot tip over and so that it
will not be near the flow of water.
Make sure that the pump 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.
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 (14), 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.
1. Attach the suction hose. Make sure to screw
it in tightly, but take care not to damage the
threads.
2. When laying the suction hose, make sure that
it is lower than the system.
Attaching the pressure hose
1. Screw the threaded connection nipple (20)
with the round seal ring (21) into the pump
outlet (3).
2. Attach the elbow nipple (18) to the connection
nipple (20) and turn the nipple so that it points
in the desired direction.
3. Attach a hose to the elbow nipple.
4. Clear the pressure line (open valves, spray-
ers, etc.).
Filling the pump
CAUTION!
Before putting your domestic water sys-
tem into operation, you must fill the pump
chamber with water until it overflows to
achieve full suction power. Do not ope-
rate the pump while it is dry because this
will cause serious damage to the pump.
1. Remove the filler screw (2).
2. Pour water into the opening until the chamber
of the pump (8) is full.
3. Replace the filler screw (2) and tighten it.
Switching the pump on and off
CAUTION!
Make sure that the pump does not run on
a blocked or closed pressure hose.
1. Plug the electric cable into the socket.
2. Clear the pressure line (open valves, spray-
ers, etc.).
3. Switch the pump on by pushing the switch (6)
to On.
4. Switch the pump off by pushing the switch (6)
to Off.
