When using universal swivel
plings (bayonet couplings), only
use versions with an additional
securing ring to ensure safe seal-
ing.

6.1 Setting pilot pressure
Set the pilot pressure before initial operation. See
section 9.4.
6.2 Installation
The device must be positioned on a horizontal, flat
surface that is suitable fo
water filling.
To avoid vibrations, the device should not be
bolted on but rather should
resilient base.
The place of installationshould be well ventilated
and protect against weather influences. Protect
against frost - see section 8.2.
For operation in garden ponds and
swimming pools, the device must
be installed in a flood-proof loca-
tion and secured against falling in.
Additional statutory requirements
must be taken into consideration.

the installation of check valves at the in
opening of the suction hose and at the suction

6.5 Connection
To reduce vibration and noises, th
be connected with flexible h
network.
6.6 Mains connection
Danger! Risk of electric shock!
Never operate the device in a
wet environment and only under
the following conditions:
- Connect only to an
that is properly installed, earthed
and tested.
- Mains voltage, mains frequency
and fuse protection must corre-
spond to those stated in the
'Technical Specifications'.
- The device
a residual-current device (RCD)
with a rated residual current of
max. 30 mA.
- The electrical connections must
not be under water and must be
located in a flood-proof area. The
connections must be splash-
proof for outdoor use.
- Extension cables must have
sufficient co
sections. Unroll cable reels fully.
- National in
tions must be observed.
6.7 Filling pump and suction
Caution! In the case of a new connec
water loss or air intake, the pump must
filled with water. Operation of the pump without
water filling

Note:
The suction line does not need to be filled
because the pump
the length and diameter of the line, however, it may
take some time until pressure is built up. To
shorten the suction time: in
the intake opening of the suction hose and fill the
suction line too.
Caution! The pump and suction line must be
connected and filled (see section 6.).
Caution! The p not be allowed to
run dry. There must always be sufficient

If the pump is blocked by foreign bodies or the
motor is overheated, a protective circuit shuts
down the motor.

Functional principle: the device switches on when
the removal of water causes the water pres
fall below the swi
again when switch-off pressure is reached. The
pressure vessel contains a rubber bellows, which
is under air p
ered; this permits the re
water without the pump starting up.
