WARNING

Turn off ALL electrical power to the furnace when conduct- ing any service or inspection procedure. Furnace may have isolated electrical supplies - one providing power to the Circulating Blower (230V or 115V) and another supplying the control circuit (115V) which controls the Circulating Blower. The spring loaded safety cutoff switch, mounted to the blower deck DOES NOT interrupt ALL electrical poten- tial in the blower compartment when the blower access panel is removed.

Filters are to be applied external to the furnace cabinet and are typi- cally installed in return-air ducting.

Return-air duct(s) may consist of either bottom only, or bottom and one side. Single-side or Dual-side returns are NOT ALLOWED.

NOTE: Some installations may have more than one return duct and each duct may have more than one filter.

Clean or replace all filters in accor- dance with the recommendations above. Replace any filter with the same type filter and consult a qual- ified service person if filter substitu- tion is necessary. When servicing the filter(s) observe direction of air- flow on reassembly. Filters should completely cover the sheet metal

opening of the ductwork to be effective. Filters should not shift collapse or dislodge from the installed position during operation.

A factory supplied (external) Bot- tom-return Filter Accessory is avail- able. This accessory kit requires the use of (2) 16" x 28" x 1" wash- able (woven) filters or (2)16" x 28" x 2" disposable (Fiberglas) filters. Filters for this kit can be accessed by removing the snap-on cover plate and sliding the filters out of their support frames. Filters are not supplied with this kit.
