The chemical product used must have a phosphoric acid base phosphoric acid base phosphoric acid base phosphoric acid base at a concentration of 35 ÷ 40 %. It may contain an anti-
foaming agent. A chemical concentration of approximately 10 ÷ 15% 10 ÷ 15% 10 ÷ 15% 10 ÷ 15% of the capacity should be used in the boiler. This
concentration depends on the degree of lime scale saturation and the effectiveness of the chemical product. Please refer to
the supplier for advice on the method of application.
When the over automatically detects an excess level of lime scale in the pipes, the text DESCALING flashes on the
display. The speed of the flash increases with the need for decaling, and when descaling is obligatory the message is
permanently lit and the boiler heating is blocked (at this point the oven only operates in convection mode).

In any operating mode, if the TG probe reaches:
o
125 ºC The message “DESCALE” “DESCALE” “DESCALE” “DESCALE” is displayed in the upper text of the screen, and flashes every two seconds.
o
140 ºC The message “DESCALE” “DESCALE” “DESCALE” “DESCALE” is displayed in the upper text of the screen, and flashes every one second.
o
155 ºC The message “DESCALE” “DESCALE” “DESCALE” “DESCALE” is displayed in the upper text of the screen, and flashes every ½ second.
o
180 ºC The message “DESCALE” “DESCALE” “DESCALE” “DESCALE” is displayed continuously in the upper text of the screen, and the oven only
operates in
Convection mode
.
Once the message “DESCALE” “DESCALE” “DESCALE” “DESCALE” has been displayed, it will not disappear until descaling takes place, even though the
TG temperature falls or if the oven is switched off. The message reappears when the oven is switched on.

Phase 1: Phase 1: Phase 1: Phase 1: VAC operates for 3 minutes
The message “SPRAY “SPRAY “SPRAY “SPRAY DESCALER” DESCALER” DESCALER” DESCALER” is displayed and the process waits until the message is confirmed. Undo the side
panel of the oven and access the steam generator. En los modelos ELECTRICOS ELECTRICOS ELECTRICOS ELECTRICOS, undo the descaling nut and pour the
descaler in the steam generator. En los modelos a GAS GAS GAS GAS soltar el conducto de vapor a cámara e introducir el
desincrustante.
Phase 2:
Phase 2: Phase 2: Phase 2: VDV operates until reaching the maximum level, the boiler fills with descaler and water.
Phase 3:
Phase 3: Phase 3: Phase 3: CV operates until TG reaches 61ºC. When TG falls below 58 ºC, CV enters again until reaching 61ºC, this
continues for the period selected by the user. The display shows a countdown for the time remaining.
Phase 4:
Phase 4: Phase 4: Phase 4: VAC operates for 3 minutes
Phase 5:
Phase 5: Phase 5: Phase 5: VDV operates until reaching N.max.
Phase 6:
Phase 6: Phase 6: Phase 6: VAC operates for 3 minutes.
Phase 7:
Phase 7: Phase 7: Phase 7: VDV operates until reaching N.max.
Phase 8:
Phase 8: Phase 8: Phase 8: Steam mode operates until TC reaches 95ºC.
If, during the descaling cycle, the operation is aborted or the oven is switched off, proceed as follows:
- If it has not reached phase 2 The cycle is ended
- If it has reached or exceeded phase 2 The cycle goes to phase 4.
- If it has reached phase 4 The cycle goes to the phase in which it stopped
