Cased Horizontal
CK3B
Furnace Coil
Sizes A024 thru A060
This horizontal N-Coil is designed to provide the highest
standard of reliability and durability. The CK3B coil casing is
unpainted embossed galvanized steel. The cabinet is fully
insulated to minimize energy loss.
The CK3B is designed for application with horizontal furnaces.
The 2-directional airflow allows for either horizontal-right or
horizontal-left furnace fit-up. This coil is ideally suited for either
attic or crawl space installation.
Our advanced manufacturing methods give a better bond of the
fin and tube. Contaminants are not introduced into coil during
manufacturing. Galvanic action is minimized. The coils are
approved for air conditioning or heat pump application in the
horizontal configuration.
The CK3B coil includes a refrigerant control metering device for
improved serviceability over check valves and expansion
devices used in conventional coils. Sweat-type connections are
furnished for installation of the refrigerant tubes.
The coil is designed to provide improved condensate removal.
The robust condensate pan has brass inserts in the primary and
secondary drain connections and meets FHA requirements.

SERVICE TRAINING
Packaged Service Training programs are an excellent way to increase your
knowledge of the equipment discussed in this manual, including:
• Unit Familiarization • Maintenance
• Installation Overview • Operating Sequence
A large selection of product, theory, and skills programs is available, using popular
video-based formats and materials. All include video and/or slides, plus companion
book.
Classroom Service Training plus "hands-on" the products in our labs can mean
increased confidence that really pays dividends in faster troubleshooting, fewer
callbacks. Course descriptions and schedules are in our catalog.
