WARNING: Never use compressed air or a brush to clean
filters, otherwise damage to the filter membrane will occur
which will allow dust to pass through the filter. If needed,

is typically unnecessary, even if the filter is covered with
dust. The automatic filter cleaning system will maintain
maximum performance and continue to function. If visual
damage to the filter membrane exists, replace filters. Filters
typically last between six and twelve months depending
