signed for outdoor use – minimum cross-sec-
2
tion 3 x 1.5 mm , quality of H07RN-F as per
DIN 57282/57245 with splash-proof plug

4 INSTALLATION
4.1 Install the pump
1. Prepare a level and sturdy installation loca-
tion.
2. Install the pump horizontally and where it will
not be flooded.
3. If necessary, bolt down the pump at the bolt-
ing points (7).
■
The pump must be protected from rain and
direct water jets.
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 suction line (17) such
that the pump cannot run dry. The suction
line must always be at least 30 cm under the
water surface.
2. Connect the suction line. Ensure that the
connection is tight, but take care not to dam-
age the thread.
3. If the water carries a small amount of sand, a
pre-filter must be installed between suction
line and pump inlet. Ask your specialist deal-
er.
4. 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 Install pressure line
1. Screw connecting nipple (15) with round seal
ring (16) into pump outlet (4).
2. Screw elbow nipple (13) with seal (14) onto
connecting nipple (15) and turn the elbow
nipple in the required direction.
3. Connect pressure line (11) to elbow nipple
(13).
5 START-UP
NOTE On initial commissioning, all informa-
tion appears on the display in English. Select the
desired language with the MODE button and con-
firm with the SET button. The air pressure in the
storage vessel can now be checked.
5.1 Check the air pressure in the storage
vessel
NOTE Operation is not possible under an air
pressure of under 1.5 and over 1.9 bar. The
pump does not start.
1. Remove the mains plug of the pump.
2. Push valve cover (27) on the rear of storage
vessel (6) upwards.
3. Check the air pressure at valve (28) using an
air pump or tyre filler equipped with a pres-
sure gauge.
4. Close valve cover on the rear of the storage
vessel again.
5. Insert the mains plug again.
■
The pump can now be put 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.
NOTE Fill the suction hose with water before
screwing in place to reduce the suction time.
1. Open filling screw (3) using filter wrench (18/
A).
2. Pour in water through the filling screw until
pump housing (2) is full.
3. Screw in filling screw.
5.3 Initial commissioning
The display shows NORMAL X and PRESSURE
only during initial commissioning.
