General Information; Coil Specifications - Nordyne C5DA Installation Instructions Manual

1. GENERAL INFORMATION

C(*)DA coils are designed for upfl ow and down-
fl ow furnace/air handler applications. The C(*)DA
coils are furnished with down-turned refrigerant
connections, ready for brazing.
Read the installation manual supplied with the
outdoor unit for refrigerant line connection pro-
cedure, required line sizes, and other information
pertaining to the system installation.
1. Make certain that the air delivery of the
furnace/air handler is adequate to handle
the static pressure drop of the coil, fi lter, and
duct work.
2. In orifi ce style models check the orifi ce size
of the coil's expansion device and confi rm
that it is suitable for application with the
intended outdoor unit.
3. Where precise forming of the refrigerant
lines is required, a copper tubing bender
designed for the size lines used is recom-

NOTE: Optional cooling/heating equipment must
be properly sized and installed in accordance
with the furnace manufacturer's specifi cations
and approved recommendations. "Heating only"
furnace air circulators may have to be replaced
with multi-speed "Heating/Cooling" blowers to
upgrade the air delivery (CFM) when an add-on
coil is installed. Refer to Coil Specifi cations for
recommended CFM and allow for pressure drop
across the coil and fi lters.

mended. Avoid sharp bends and contact of
the refrigerant lines with metal surfaces.
Refrigerant lines should be wrapped
with pressure sensitive neoprene or other
suitable material where they pass through
the raw edges of holes.
The coil enclosure (if provided) and suction
line must be insulated as needed to prevent
condensate from forming and causing
property damage.
Coil must be level for proper conden-
sate drainage.
Do not remove seals from the coil until the
tubing connections are ready to be made.
