	The CAF Chilled Water Cassette Evaporator is
	available in three cabinet sizes with six cooling out-
o	put capacities from 8,000-36,000 Btuh. Fan speed
	adjustments are available in all three cabinet sizes
i	to obtain required performance. Key features include
	a condensate pump with safety switch and an 30” lift;
t electric heat; fresh air inlet and branch duct knock-
a	outs; and motorized air vanes (18-36 only). the caf
	accepts a 24 volt thermostat control (thermostat not
c
	included) or an infrared microprocessor control can
	be obtained as a factory installed option. Hot water
i
	coils are available on all CAF models (except for
f
	12,000 Btu) in place of electric heat.
i	Due to ongoing product development, all designs
c
	and specifications are subject to change without
e notice.

Air Systems:

•Fans are backward curved impeller centrifugal design; dynamically and statically balanced; and mounted on integral mounting rails.

•Single Fan models (08-20) designed with fire retardant aluminum/plastic impellers.

•Twin Fan models (33-36) designed with fire re- tardant plastic impellers.

•Motors are multispeed, enclosed type with thermal protection and sealed lifetime bearings.

•Permanent, washable filter (user accessible).

•Branch duct knockouts on two sides for remote discharge locations.

•Fresh air intake capability on three sides of cabi- net (2 on CAF 08-12).

•Four flock coated air vanes; motor driven with auto sweep or fixed position stop setting on models

18-36 (models 08-12 equipped with manually adjusted air vanes).

Coil - is seamless, rifled copper tubing, arranged in staggered configuration, with enhanced aluminum fins tested to 460 psig. The tubes are mechanically expanded for secure bonding to the fin shoulder.
