External Filter Maintenance
Aluminum mesh, 2-inch deep filters are located in the
supply weatherhood (if the weatherhood option was
purchased). Filters should be checked and cleaned
on a regular basis for best efficiency. The frequency of
cleaning depends upon the cleanliness of the incoming
air. These filters should be cleaned prior to start-up.
Clean filters by rinsing with a mild detergent in warm
water.
