Switch off the plant, turn the emergency
stop main switch in the electrical switches
cabinet to "0".
Turn the emergency-stop switch to "1".
Immersion pump is working when:
– The water level in the recycled water
tank is below the starting level S7.
– The water level in the pump basin is
above the starting level S15.
Turn the programme selector switch to
the desired position.
Press the SET key.
NOTICE
After the switching on of the emergency off
switch, the system will start in the mode
"Operation without conductivity monitor-
ing“.
– With this function, the recycled water is
channeled from the pump basin into a
channel.
– This function is required when the qual-
ity of the recycled water proves insuffi-
cient for operating the awashing system
(too much salt in the water or wrong
cleaning agent, for example).
Function:
Turn the programme selector switch to
position "Pump basin".
Press the SET key.
– The system filters until the S15 switch in
the pump basin signals lack of water
and the submersion pump is switched
off.
– This overflows the recycling water con-
tainer. The excess water flows over the
overflow line of the recycling water con-
tainer and into the channel.
– The water supply of the washing sys-
tem now runs with fresh water until the
pump basin is filled up to level S15 at
the top, and the deactivation of the sub-
merged pump is cancelled.
– Recycled water can then be produced
in the normal way.
– KÄRCHER Service deactivates the
"Draining the pump basin" function if
there is an overflow line from the pump
basin into the channel.
– When there is no overflow from the re-
cycling water container into the chan-
nel, the function “empty pump basin” is
deactivated by KÄRCHER Service.
– The unit is equipped with the option of
an automatic monitoring of the conduc-
tivity.
– The measuring point is located at the
recycling water line between the hydro-
cyclone and the recycling water con-
tainer.
– This conductivity monitoring function
can be activated or deactivated here.
– When the preset value for the conduc-
tivity is exceeded, the conductivity mon-
itoring triggers the same process as the
"Empty pump basin" button.
– The subsequent utilization of fresh wa-
ter for the washing process dilutes the
remaining salty water in the basin sys-
tem to an extent that adequate washing
water quality is restored.
In this operating mode, the washing bay is
operated with fresh water only.
If the washing system does not use up the
water, the recycled water is circulated to
avoid foul odour.
The plant must be operated in frost-free
rooms. During frost, put the system out of
operation and remove all traces of water:
Loosen the screws of the plastic pipes
and let the pipes run empty.
Empty recycling water container.
NOTICE
To
avoid odour problems, the plant must
remain switched on even during the night.
Switch off the plant, turn the emergency
stop main switch in the electrical switch-
es cabinet to "0".
If there is risk of frosting, then any exist-
ing water traces must be removed (see
section "Anti-freezing").
During fresh start-up after shutdown:
