10-SAFETY DEVICES AND ALARMS
BLOCKED APPLIANCE
The following may cause the product to be mechanically blocked:
• The structure overheats (“A03”).
• The smoke is overheated (“A04”).
• During product operation, air that has not been controlled in the combustion chamber has entered or the flue is clogged. (“A05”).
SOLUTIONS:
If “ A03 ” appears: the structure is too hot because the product has been used for too long at the maximum power or due to poor ventilation
or because the air fans are faulty.
When the product is sufficiently cold, press button B on the control panel to delete alarm A03. Once the alarm is deleted, the product can
be switched on.
If “
A04
” appears, the product will shutdown automatically, let it cool down for a few minutes and then switch it on again. Delete the alarm
and switch the product on again. If “
A05
” appears: the door has been left open for too long or a significant amount of air has entered (e.g.
missing smoke fan inspection cap). If these causes are excluded, check and if necessary clean the smoke duct and flue.
Only after having eliminated the cause permanently can the product be switched on again.
