FILTERS
After commissioning, the speed of filter fouling will depend on the care taken when cleaning the air flow circuits. Hence the
frequency of filter checks should be increased during this period.
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, even in the case of moderate use
Filter replacement method
During filter maintenance operations, it is important not to spread the dust that has accumulated in the filters.
Turn off the unit.
Access the filters by opening the door panels.
Simply pull on the filters.
