FY4A, FA4C
Base Series Fan Coil
Sizes 1 1/2 — 5 Ton (018 Thru 060)
Product Data
AIR HANDLER TECHNOLOGY
AT ITS FINEST
The FY4A and FA4C direct--expansion fan coils are designed to
cover a wide range of air handling requirements. They are compact
and ready to fit where needed, in the basement, crawlspace, attic,
utility room, or closet. The unique cabinet design of these fan coils
meet new stringent regulations for cabinet air leakage, a
requirement of 2% cabinet leakage rate when tested at 1.0 inches of
static pressure.
The FY4A and FA4C units are shipped with a factory--installed
hard--shutoff thermostatic expansion valve (TXV) metering device
with an internal check valve for reverse flow bi--pass capability. All
units come with solid state fan controls, 1--in. thick insulation with
R--value of 4.2, super--quiet multispeed motors, and fully--wettable
coils. Units can accommodate factory-- or field--installed heaters
from 3 to 30 kW.
The FY4A design is a residential new construction (RNC) model
available for use with Puronr, the environmentally sound
refrigerant. It comes with or without factory--installed disconnects.
It has a pre--painted (gray) galvanized insulated steel casing,
2--speed PSC motor in the 018 through 036 sizes, and 3--speed
PSC motors in the 042 through 060 sizes. ArmorCoattprovides a
tin plating of the indoor coil’s copper hairpins. This creates a
barrier between the corrosion--causing elements and the coil.
The FA4C has all the same quality features as the FY4A, but is for
use with R--22 refrigerant.
