SECTION III: FILTERS
FILTER INSTALLATION
All applications require the use of a field installed filter. All filters and
mounting provision must be field supplied.
Filters must be installed external to the furnace cabinet. DO NOT
attempt to install filters inside the furnace.
NOTICE
Single side return above 1800 CFM is approved as long as the filter
velocity does not exceed filter manufacturer's recommendation and
a transition is used to allow use on a 20x25 filter.

1.Air velocity through throwaway type filters may not exceed 300 feet per minute
(91.4 m/min). All velocities over this require the use of high velocity filters.
2.Do not exceed 1800 CFM using a single side return and a 16x25 filter. For
CFM greater than 1800, you may use two side returns or one side and the bot-
tom or one side return with a transition to allow use of a 20x25 filter.

SIDE RETURN
Locate the "L" shaped corner locators. These indicate the size of the cut-
out to be made in the furnace side panel. Refer to Figure 14.
Install the side filter rack following the instructions provided with that
accessory. If a filter(s) is provided at another location in the return air
system, the ductwork may be directly attached to the furnace side panel.
FIGURE 14: Side Return Cutout Markings
Some accessories such as electronic air cleaners and pleated
media may require a larger side opening. Follow the instructions
supplied with that accessory for side opening requirements. Do not
cut the opening larger than the dimensions shown in Figure 13.
