Note 1: with a cooling unit over 4 tons use 2 - 16 x 25 filters on two side returns or a 20 x 25 on the bottom return.
Upflow at 1800 CFM or more: use two side returns or one side plus bottom.
Larger filters are fine; filters may also be in a central return.
Horizontal installs: filters must be outside the furnace (central return).
Filters are not supplied with the furnace; replace every two months or as needed.

For licensed technicians. Gas, electrical and refrigerant work must be done by a qualified, licensed person. Shut off power and gas before servicing, never bypass a safety control, and follow the manufacturer’s manual for the exact model; it and local codes always take priority.
