with four output capacities from 9,000 -
24,000 Btuh, and two cooling only capacities
from 30,000 - 36,000 Btuh. Key features
include a condensate pump with safety
switch and a 36” (0.9 m) lift*, electric heat is a
factory installed option ONLY
(there are no
field installed electric heat kits available)
,
fresh air inlet and branch duct knockouts,
and motorized air vanes (Cassette 24 & 36
only).
T
he Cassette air handler accepts a
24 volt thermostat control (thermostat not

easy installation and maintenance and a
slim line fascia, all ensure minimum intrusion
into the conditioned environment.
Due to ongoing product development,
all designs and specifications are subject
to change without notice.
* Condensate pump lift measured from
the base or bottom of the unit.
These American made Cassette Air
Handlers produce system SEER’s meeting
or exceeding 13, when matched with EMI’s
