NOTE In day-to-day operation (automatic
mode), suitable measures must be taken to ex-
clude the possibility of flooding of rooms as a re-
sult of malfunctions in the pump.
4.2 Connect the suction line
NOTE We recommend the installation of
flexible lines at the pump inlet to prevent me-
chanical pressure or tension being exerted on the
pump.
1. Select the length of the suction line such that
the pump cannot run dry. The suction line
must always be at least 30 cm under the wa-
ter surface.
2. Connect the suction line. Ensure that the
connection is tight, but take care not to dam-
age the thread.
3. Always lay the suction line with an upward
gradient.
NOTE If the suction head is more than 4 m,
a suction hose with a diameter larger than 1"
must be installed. We recommend the use of an
AL-KO suction unit with suction hose, suction fil-
ter and flow-back stop. Ask your specialist dealer.
4.3 Mounting the pressure line (2)
1. Screw connecting nipple (13) with seal (14)
into pump outlet (3).
2. Screw elbow nipple (11) with seal (12) onto
connecting nipple (13) and turn the elbow
nipple in the required direction.
3. Connect pressure line (10) to elbow nipple
(11).
4. Open all shut-off devices (valves, spray noz-
zles, water cock) in the pressure line.
5 START-UP
5.1 Check the air pressure in the storage
vessel
IMPORTANT! Danger of damage to the
pump! The pump may only be operated with a
diaphragm storage pressure of 1.5 - 1.7 bar in
the storage vessel. Other diaphragm storage
pressures can cause equipment damage.
■
Check the air pressure at the valve on the
back of the storage vessel before commis-
sioning.
1. Open the cover on the rear of the storage
vessel.

2. Check the air pressure at the valve using an
air pump or tyre filler equipped with a pres-
sure gauge.
3. Correct the air pressure to 1.5 - 1.7 bar, if
necessary.
4. Close the cover on the rear of the storage
vessel again.
5. Putting the pump into operation.
5.2 Fill the pump
IMPORTANT! Danger of damage to the
pump! Dry running will destroy the pump!
■
The pump must be filled with water up to the
overflow before each use so that it can draw
water immediately.
1. Open filling screw (2) using filter wrench (19/
A). (Not for INOX models)
2. Pour in water through the filling screw until
the pump housing is full.
3. Screw in filling screw. (Not for INOX models)
6 OPERATION
6.1 Switching the pump on
1. Open all shut-off devices (valve, spray noz-
zle, water cock) in the pressure line (10).
2. Insert the plug of the mains cable into the
power socket. The pumps starts to pump.
3. Close the shut-off device in the pressure line
when there are no more air bubbles in the es-
caping water.
■
The pump switches off automatically after
building up the pressure and reaching the
switch-off pressure.
■
The pump is ready for operation.
6.2 Switching the pump off
1. Remove the mains plug from the plug socket.
2. Close all the shut-off devices in the pressure
line.
CAUTION! Danger of injury from hot wa-
ter After extended use against the closed pres-
sure side (> 10 min.), the water in the pump can
become very hot and may escape uncontrolled!
■
Disconnect the pump from the mains supply
and allow the pump and water to cool down.
■
Put the pump into operation again only after
all the faults have been remedied!
