The 40QK Energy-Efficient In Ceiling

Cassette fan coil incorporates innova-

tive technology to provide reliable per-

formance. Built into these units are

features most desired by the industry

today, including SEER ratings of up to

11.3 when matched with Duct-Free

System Condensing units. All models

are listed with UL, UL, Canada, ARI,

and CEC. With a wide range of acces-

sories available to meet a variety of

installation requirements, the 40QK

series is ideal for retrofits and

modernizations with suspended ceil-

ings and can be installed in standard

2ftx2ftand2ftx4ftgrids.

Features/Benefits

Technology and components

The high-efficiency two or three-row

heat exchanger has mechanically

expanded copper tubes with continu-

ous aluminum fins. The coil connec-

tions are made of brass.

Fan motor

The direct-drive fan with backward

curved blades has a three-speed per-

manent split capacitor motor with

built-in thermal protection, regulated

by an electronic thermostat. The

motor is installed on spring anti-

vibration mounts. This fan blade design

ensures uniform airflow through the

heat exchanger.

Diffusers

Four-way air distribution gives individu-

al comfort. For localized control, each

diffuser may be adjusted or even shut

down completely. The special design

of the diffusers ensure rapid blending

of the supply and room air. Condi-

tioned air is directed along the ceiling,

then evenly distributed throughout the

room. Return air enters the cassette

unit through a large grille. It is then
