Product Data

AIR HANDLER TECHNOLOGY

The FB4C fan coil has the proven technology of Bryant fan coil
units with Puron refrigerant as well as vertical and horizontal
applications. The design features contoured condensate pans with
rugged drain connections, ensuring that little water is left in the
unit at the end of the cooling duty cycle. The lack of standing
condensate and corrosion free pans improves IAQ and product life,
features homeowners appreciate.

Standard features include grooved tubing and louvered fins. Coil
circuiting has also been updated to make the most of all Bryant
heat pumps and air conditioners. Units come with solid state fan
controls, 1--inch (25mm) thick insulation with R--value of 4.2,
multi--speed motors, and fully--wettable coils. Units can
accommodate factory-- and/or field--installed heaters from 3 to 30
kW.

It also should be noted that the unique cabinet design of these fan
coils meet stringent regulations for cabinet air leakage -- a
requirement of 2% cabinet leakage rate when tested at 1.0 inches of
static pressure.

The FB4C fan coil design is loaded with popular features. These
fan coils utilize the latest in electronic commutation motor (ECM)
technology through the use of high efficiency, multi--tap ECM
motors allowing reliable air delivery with increased static pressure.
It comes in a pre--painted (taupe metallic) galvanized steel casing
and a factory--supplied power plug for ease of installation. The
FB4C unit is shipped with a factory--installed Teflon--ring piston
