If the fault cannot be rectified by following the above instructions, please contact a specialist or our after sales service.
Cause
No regenerative in salt/brine container (6).
Power supply cut off
Inlet pressure is too low.
Compressed air pressure too low.
Regenerative was not refilled in time.
Note:
If the regenerative is refilled too late or is not
refilled (meaning that the level of regenerative
falls below the minimum or the display indicates
"low-salt"), a malfunction will occur after the
next regeneration.
Cable to the valve block is defective.
Electrolysis cell overcurrent
Maintenance must be performed after every
500 regenerations.
Action
Refill regenerative. Wait approx. 1 hour
and then regenerate manually.
Re-establish electrical connection.
Increase inlet pressure (adjust pressure
reducer if necessary) and start manual re-
generation.
Check inlet pressure and start regeneration.
The brine must be siphoned off or extracted to
the level of the sieve base. Only after this has
been done can the regenerative be refilled.
If this is done incorrectly, the softened water
will be salty.
Check the cable to the valve block and press
OK to confirm.
Contact the after-sales service staff if the
malfunction is still displayed.
Check the cable to the valve block for short
circuits and press OK to confirm.
Contact the after-sales service staff if the
malfunction is still displayed.
Contact after-sales service.
