ANTI-CALC WARNING ALARM
If you hear a beeping sound from the boiler, and at the same time all the red LED
lights are flashing (after 1 minute they will stop flashing and stay on), this means
that it is time to proceed with the de-scaling of the boiler tank.
ATTENTION:
It will be still possible to work for a short time while the boiler is
in the alarm mode, after which the steam station will auto-protect itself from the
scale and stop working until you de-scale the boiler.
SPECIAL NOTE
The J490A anti-calc warning system will automatically shut itself off after 57 gal-
lons (218 litres) of water, if the programming instructions have not been followed.
It is suggested that you first clean the boiler following the cleaning instructions
outlined on page 10. Then programme the anti-calc system following the instruc-
tions above (#2 – #5) to reset the programmer.
RESET THE PROGRAMME
Once you have de-scaled the boiler (see section Maintenance of the Boiler) you
have to proceed with the RESET before starting to iron again. Repeat step #2
(in the programme instructions above and hold the "R" button down for 10 seconds.
When you hear the beap, the programme is reset.
