NOTE − 60C and 60D size units that require air volumes over
1800 cfm (850 L/s) must have one of the following:
a. Single side return air with transition, to accommodate
20 x 25 x 1 in. (508 x 635 x 25 mm) air filter. Required to
maintain proper air velocity.
b. Single side return air with optional RAB Return Air Base
c. Bottom return air.
d. Return air from both sides.
e. Bottom and one side return air.
See Blower Performance Tables for additional information.
