    Air Filters and Screens

    Each unit is equipped with return air filters. If the unit has an economizer, it will also have an outside air screen. If a manual outside air damper is added, it will also have an inlet air screen

    Each of these filters and screens will need to be periodically replaced or cleaned.

    ! CAUTION

    EQUIPMENT DAMAGE HAZARD

    Failure to follow this CAUTION can result in premature wear and damage to equipment

    DO NOT OPERATE THE UNIT WITHOUT THE RETURN AIR FILTERS IN PLACE.

    Dirt and debris can collect on heat exchangers and coils possibly resulting in a small fire. Dirt buildup on components can cause excessive current used resulting in motor failure.

    Return air filters are disposable fiberglass filters. Access to the filters is through the lift-out filter access panel located on the rear side of the unit, above the indoor coil access panel. See Fig. 2.

    Outside Air Hood

    Outside air hood inlet screens are permanent aluminum-mesh type filters.

    Check these for cleanliness.
