NOTICE
Check the inlet quantity!
The maximum inlet volume flow must be less than
the maximum pump delivery rate. If the inlet quant-
ity is higher, the pump will not be able to pump
away the volume flow. The pump chamber may
overflow!
6.1

Before activating

Check the following prior to activation:
• Has the electrical connection been carried out in accordance
with regulations?
• Has the connection cable been routed safely?
• Can the float switch move freely?
• Temperature of the pumped fluid observed?
• Immersion depth observed?
• Are the pressure pipe and pump sump free of deposits?
• All gate valves in the pressure pipe open?
6.2

Switching on and off

The pump will switch on and off automatically on reaching the
switching level:
• Upper floater: Pump on.
• Lower floater: Pump off.
6.3

Test run

If the pump is installed stationary (e.g. cesspool, overflow shaft),
carry out a test run. Check the following points with the test run:
• General conditions (inflow quantity, switching points)
• Direction of rotation (with 3~ motors)
The test run must include three pump cycles.
1. Flood the pump chamber: Open inlet.
NOTICE! The required feed quantity for the test run can also
be simulated using another water source.
2. When the switch-on level is reached: pump starts.
3. Switch-off level reached: pump stops.
4. Repeat two more pumping processes.
▶ Once three pumping processes have been completed
without problems, the test run is finished.
NOTICE! If the pump does not switch on once a week, repeat the
test run every month.
6.4

Turning automatic mode on and off

Turning automatic mode off
The pump normally runs in automatic mode. The attached float
switch is used to switch the pump on and off depending on the
level. If necessary, automatic mode can be turned off.
NOTICE
Automatic mode off: pump starts immedi-
ately!
When the plug is inserted into the socket, the pump
immediately starts! We recommend switching the
socket on and off using a separate main switch.

✓ Pump removed.
✓ Pump disconnected from mains.
1. Loosen cable clamp on handle.
2. Remove floater cable from cable clamp.
3. Position the floater upwards ("pump on" position).
4. Insert floater cable in cable clamp.
5. Pull the floater toward the cable clamp.
6. Push cable clamp into handle.
▶ Affix floater to handle. Automatic mode off, continuous
duty on.
Turning automatic mode back on
To turn automatic mode back on, remove the floater from the
handle. For automatic mode to run properly, adjust the cable
length via the cable clamp to ensure the floater cable is long
enough.
CAUTION! Cable damage! Always loosen the cable clamp on the
handle when adjusting the cable length.

During operation

CAUTION
Do not allow the pump to dry run!
Do not run the pump without fluid (dry run). Switch
off the pump once the residual water level has been
reached. Dry running may destroy the seal and cause
the pump to be irreparably damaged.
