    13 - MAINTENANCE 13.1 - Filters Check the filters frequently when commissioning the unit. The rate at which they will clog will depend on how well the air circuits  were cleaned. Maintenance intervals The filter life depends essentially on the amount of dust in the air and the efficiency of the filtration system. The filtration quality  cannot be maintained if the filter medium has been damaged during maintenance. We recommend that the filters be replaced once  every two years in case of low to moderate use. Replacing the filter elements  When performing maintenance, it is important to avoid releasing and spreading the dust that has accumulated in the filter. Turn off the unit. Access the filters by opening the doors on the front. For filter sizes CW 40 to 100 Replace the used filters by new filters. Take care to note the direction of air flow indicated on the new filters.
