INSTALLATION OF THE PRESSURE LINE
The pressure line 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 water outlet (1)
of the pump.

WARNING
WARNING
Please make sure that the pump will cut out as soon
has reached the cut-out level.
Also it must be made sure that the floating switch
can move freely.
The pump MUST be attended when used in this mode
as the motor receives no cooling and can over heat.
HOW TO POSITION THE PUMP
1. Screw the connection adaptor (10) into the pump
outlet.
2. Screw the connection port into the connection
adaptor.
3. Fix a hose to the combination nipple, use a hose
clamp to secure the hose.
STATIONARY INSTALLATION
If the unit is used in a stationary installation, rigid pipes
have proven to be the ideal choice for the pressure
lines. In this type of installation, we recommend that
you incorporate a check valve (non-return valve) in the
pressure line immediately following the pump outlet
To facilitate maintenance work, we also recommend
the installation of a stop cock valve downstream of the
in that closing the stop cock will prevent the pressure
line from running dry after the disassembly of the pump.
HOW TO SET FLOAT SWITCH
The pump is fitted with a float switch, which controls
1. When the float switch is about 30° higher than
horizontal (start up level) or above the handle, the
pump will turn ‘on’ and operate.
(Fig. 1)
2. When the float switch is 30° lower than the
horizontal or below the handle, the pump will turn
‘off’.
(Fig. 2)
3. To set the pump to switch off at a lower water level,
insert the float switch cable into the adjuster Note:
There must be a minimum of 100mm of cable from
the adjuster to the float.
(Fig. 3)
4. Manual mode: when the float is manually secured at
ON position, the pump can draw down to a minimum
level of 54mm (at 0m delivery height)
(Fig. 4)
■
When positioning the pump, please make sure that
the max. immersion depth indicated in the technical
data will not be exceeded.
■
Likewise, please make sure that the minimum
selfpriming level is not fallen short of. If everything
is properly set, the water level may decrease
down to the minimum suction level once the pump
is operating. Please position the pump on solid
ground. Avoid placing it on lose stones or sand.
■
When positioning the pump, elevate it from the
bottom such that sediment and debris will not be
sucked into the inlet. This will protect the impellers
as well as maintain flow performance
■
To position, lift up or carry the pump, please use
only the carrying handle(7).
■
If required for lowering or raising the pump, you
must connect a suitable lowering rope to the
carrying handle. Do NOT lift pump using the hose,
power cord or float cable.
ELECTRICAL CONNECTION
■
The unit is equipped with a power connection cable
and a plug. It must only be replaced by qualified
staff to avoid any danger. Please do not use the
power cable to carry the pump, and do not use this
cable to pull off the plug from the socket, either.
Protect the power 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 circuitbreaker
(FIswitch) :
Δ
= 30 mA.
■
If extension cables are used, their cross-section
must not be smaller than that of rubbersheathed
cables of the H07RN-F (3 x 1,0 mm²) short code.
The mains socket and the plugand-socket elements
have to be in splash water-proof design.
PUTTING INTO OPERATION
■
Nobody must be in the water while the pump is
running.
■
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.
■
Please make sure that the electrical plug
connections are in flood-proof area.
■
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.
■
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 connection. A damaged pump must not be
used. In any case of damage, the pump has to be
