Operation
Grease filter timer
A timer monitors the hours of fan opera- tion. The indicator for the grease filter will light after 30 hours of operation. The grease filters must then be cleaned.
After the grease filters have been cleaned and put in place, the grease fil- ter timer must be reset.
^To do this, press the grease filter but- ton for about 3 seconds.
The indicator will go out.
Checking the grease filter timer
To check the percentage of time al- ready used:
^Press the On/Off button to turn the fan on.
^Press the grease filter button.
The number of flashing pm indica- tors show the percentage of pro- grammed hours that have been used.
1 indicator = less than 25 %
2 indicators = less than 50 %
3 indicators = less than 75 %
4 indicators = less than 100 %
This information will remain stored in memory in the event of a power failure.
