NOTE: Some filters are marked with an arrow to indicate the proper direction of air flow through the filter. The air flow direction will be towards the blower motor. Make sure filter is installed correctly. Filter Replacement The filter may be installed inside the bottom of the furnace blower compartment, or the filter(s) rack may be installed under the furnace or on either or both sides of the furnace. A plastic end cap(s) is inserted in the filter rack(s) after the filter(s) is installed. The end cap keeps air from escaping around the open end of the filter rack. See Fig. 4 and Fig. 5 for side and bottom locations. Rack end cap is similar for bottom mounted filter rack. Filter rack(s) attached to the outside of the furnace is made so the filter simply slides out one end for removal. 359BAV 5 6 PROPERTY DAMAGE HAZARD Failure to follow this caution may result in increase furnace operating temperatures and shorten the life of the furnace. Filters specified for the furnace are rated at a maximum of 600 FPM air velocity and sized for the furnace’s airflow rate. Replacement filters must be of equivalent type, size, and rating except as described below. Disposable, low--velocity filters may be used to replace washable, high--velocity filters, providing they are sized for 300 FPM or less. If you are uncertain of the type of replacement filter to use, consult the furnace installer or a qualified service agency for assistance. !
