5.3. INSTALLATION OF THE PRESSURE LINE
The pressure line (2) conveys the liquids to be
discharged 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 (5) of the pump.
Also,
to
facilitate
recommendable to install a shut-off cock (9) 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
accessibility 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.
5.5. USING THE PUMP FOR GARDEN PONDS
AND SIMILAR PLACES
Operating the pump next to garden ponds
and similar places is generally only
admissible if no persons are in contact with
the water.
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.
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
maintenance
work,
it
adequate
visibility
and
a highly sensitive residual current circuit-breaker (FI
switch): Δ = 30 mA.
• If extension cables are used, their cross-section
must not be smaller than that of rubber-sheathed
cables of the H07RN-F (3 x 1,0 mm²) short code.
The mains socket and the plug-and-socket elements
have to be in splash water-proof design.

7. PUTTING INTO OPERATION
• Please observe the illustrations, too, which are
contained as an attachment at the end of the
present operating instructions. The numeric and
other details included in brackets below refer to
these illustrations.
• Prior to putting the pump into operation for the
very first time, the pump housing should be fully
vented - i.e. filled with water - even in the case of
self-priming units. If this venting is omitted, the
pump will not suck in the liquid to be discharged.
It is highly recommendable, yet not mandatory, to
vent the intake line as well, i.e. to fill it with water.
• The pump must only be operated in the performance
range indicated on the type plate.
• Dry-running - i.e. operating the pump without
discharging water - is to be avoided since the
absence of water may cause the pump to run
hot. This may cause considerable damage on
the device. Moreover, this means that very hot
water will be enclosed within the system so that
there is a hazard of scalding. If the pump has
run hot, please pull off the mains plug and allow
the system to cool down.
• Please do not expose the pump to moisture (e.g.
when operating sprinklers). Do not expose the unit to
rain, either. Make sure that no dripping connections
are located above the pump. The pump should not
be used in wet or moist environments. Make sure
that the pump and the electrical plug connections
are arranged in a flood-proof place.
• The pump must not be running with the feeder line
closed.
• As long as the device is connected to the electrical
mains, one must never reach with one's hands into
the opening of the pump.
Each time the pump is put into operation, please
make sure that the pump is set up securely and
firmly standing. The unit must always be positioned
upright on an even surface.
Please inspect the pump visually prior to each use.
This applies in particular to the mains connection
line and the mains plug. Make sure that all screws
are firmly tightened, and verify the perfect condition
of all connections. A damaged pump must not be
used. In any case of damage, the pump has to be
