^The steam coils in models 65 and 75 are not type 5. They are type 8 coils with 1" diameter tubes on 3" centers. * The CFM range for cooling and heating starts at a low of about 400 fpm through small coil.

The maximum CFM for cooling is at no more than 550 fpm through a large coil. The maximum CFM for heating is at no more than 900 fpm through a large coil. The fan tables are on pages 24 through 29.

Fan Type	Bearings	Coils	Filters
FC = Forward curve fan	(Ball Type)	FH X FL	1-24 X 24	Means one 24" by 24 “ filter
AF = Airfoil fan	C = Cartridge	FH = Finned Height , inches
Shaft Diameter is inches	PB = Pillow Block	FL = Finned Length, inches
		TH = Tubes High
		FACE AREA is in Square Feet.
		Refrigerant can be either direct	expansion, heat	reclaim , or condenser coil.
