6.Replace filter compression plate(s).

7.Close and latch access door(s).

8.Turn on power to the fan.

9.Proper filter disposal is important to the environment. Refer to local landfill codes.

Carbon Panel Replacement

Unlike particulate filters, technology has yet to develop a cost-friendly method of determining when the carbon panels need replacing. So, the industry standard is the human sniff test. As the carbon begins to lose its effectiveness, odor breakthrough gradually occurs and odor concentration increases. Based on a variety of cooking applications/installations, life of the carbon panels can range from a few months to one year. Replace carbon panels when odor breakthrough is first noticed. When replacing carbon panels, follow the instructions in the Operation section, Filter Replacement, Steps 2-10. There is no particular direction of airflow for carbon panels.
