5.2. INSTALLATION OF THE SUCTION LINE
The intake of the suction line has to be
equipped with a check valve
return valve) and an intake filter.
It is mandatory to install a second non-return
valve between the suction pipe and the pump.
3B
This valve prevents leakage on the suction line
causes continuous operation of the pump.
Please use a suction line (1) having the same
diameter as the suction port (6) of the pump. If
the suction height (HA) exceeds 4 m, however, it
is recommendable to use a 25% larger diameter
- including appropriate reducer elements for the
connectors.
The intake of the suction line has to be equipped
with a check valve
an intake filter (2). The filter will keep away larger dirt
particles contained in the water which might clog or
even damage the piping. The check valve will prevent
the pressure to escape after the pump has cut out.
Moreover, it simplifies the venting of the suction line
by enabling water to be filled in. The check valve
with the intake filter - i.e. the entirety of the intake
section of the suction port - must be immersed by
at least 0.3 m below the surface of the liquid to be
pumped (HI). This will prevent air from being taken in.
In addition, please ensure a sufficient distance of the
suction line from both the ground and the sides of
water courses, rivers, ponds etc in order to prevent
stones, plants etc from being sucked in.
It is mandatory to install a check valve between the
suction pipe and the inlet of the pump.
This non-return valve prevents back pressure in the
suction pipe.
5.3. INSTALLATION OF THE PRESSURE LINE
The pressure line (4) conveys the liquids to be dis-
charged from the pump to the point of withdrawal.
To avoid dynamic flow losses, one should use a
pressure line having at least the same diameter as
the pressure port (7) of the pump. Also, to facilitate
maintenance work, it is recommendable to install a
shut-off cock (5) after the pump and check valve.
This is a useful feature since it can be closed when
the pump has to be dismantled and will thus prevent
the pressure line from draining to empty.
5.4. STATIONARY INSTALLATION
With regard to the electrical connection in
the case of stationary installation, please
ensure an adequate visibility and accessi-
bility of the plug.
For stationary installation, please fasten the pump
on a suitable, solid surface. To reduce vibration, it
is recommended to apply an anti-vibration material
- for instance a rubble layer - between the pump and
the installation surface (16).

5.5. USING THE PUMP FOR GARDEN PONDS
AND SIMILAR PLACES
Operating the pump next to garden ponds
and similar places is generally only admis-
sible if no persons are in contact with the
water.
The use of the pump as a recycling pump or
as a closed circuit pump is prohibited.
If the pump is used for garden ponds and
similar places it has to be operated using a residual
current circuit-breaker (FI switch) with a nominal
trigger current of ≤ 30mA. Please ask your electrical
services provider whether your installation site
complies with this condition.
The pump must not be used in such locations
unless it is set up firmly and flood-proof, a minimum
distance of two metres away from the border of
the water body and secured against falling into the
water by a solid holding device. For this purpose
the device is to be bolted down firmly to the ground
at the fastening points provided (please refer to the
chapter titled "Stationary installation").

6. ELECTRICAL CONNECTION

• The unit is equipped with a mains connection cable
and a mains plug. It must only be replaced by
qualified staff to avoid any danger. Please do not
use the mains connection cable to carry the pump,
and do not use this cable to pull off the plug from
the socket, either. Protect the mains connection
cable and mains plug from heat, oil or sharp edges.
• The values stated in the technical details have
to correspond to the mains voltage. The person
responsible for the installation has to make sure that
the electrical connection is earthed in compliance
with the applicable standards.
• The electrical connection has to be equipped with
a highly sensitive residual current circuit-breaker (FI
switch) : Δ = 30 mA.
• Only use an extension cable with a cable section
(3 x 1.0 mm²) and rubber sheath which at least
corresponds to that of the unit's own connection
cable (see "Technical data", cable type) and which
is labelled with the relevant abbreviation according
to the VDE (German Association for Electrical,
Electronic & Information Technologies). The mains
plug and other connections must be splash-proof.
