  • A-Filters

  • Filters may be duct-mounted or installed in the cabinet. A filter is installed at the factory. Note that filter access door fits over access panel. Air will leak if the access panel is placed over the filter door.

  • Filters should be inspected monthly and must be cleaned or replaced when dirty to assure proper air handler operation. Units are equipped with standard throw-away type filters which should be replaced when dirty.

  • To remove filter, loosen the thumbscrews holding the filter panel in place. Slide filter out of the guides on either side of cabinet, insert new filter and replace panel.
