Functions
Filter alarm
Is shown for 30 sec. when the motor is switched off. After an operation period of 30 hours the middle
segment on the display will light up to indicate that the anti-grease filter needs to be cleaned. After
an operation period of 120 hours the middle segment on the display will blink to indicate that the
grease filter needs to be cleaned and that the charcoal filter needs to be replaced.
After the grease filter has been cleaned (and/or the charcoal filter has been replaced), button C
(RESET) needs to be pressed while the filter alarm is being indicated in order to reset the hour
metre.
Sensitivity of the gas sensor
The sensitivity of the gas sensor may be adjusted to suit the personal needs of a user.
To adjust the sensitivity, the appliance must be in the manual operation status (i.e. the letter A is
not shown on the display, instead the current speed is shown).
Button E may need to be pressed.
The degree of sensitivity can be adjusted by pressing buttons D and E simultaneously. The display
shows the level of sensitivity which has been set (from level 1 = lowest sensitivity to level 9 = highest
sensitivity).
Use buttons C (-) and D (+) to set the required level of sensitivity.
Pressing button E will store the “new” sensitivity setting.
