AIRFLOW CAPACITIES
600-1,900 CFM
[283-897 L/s]
Rheem®Indoor Coils are designed for use with Rheem outdoor units and are available for vertical upflow or downflow,
and horizontal left or horizontal right airflow. When matched
with Rheem outdoor units, the coils provide a nominal
capacity range from 18,000 BTU/HR [5.24 kW] to 60,000
BTU/HR [17.58 kW].
■ Constructed of aluminum fins bonded to internally
grooved copper tubing.
■ Coils are tested at the factory with an extensive refriger-
ant leak check.
■ Coils have sweat refrigerant connections.
■ Ideally suited for new installations or add on air
conditioning.
■ Feature two sets of
3
/4" [14.1 mm] N.P.T. Condensate
drain connections for ease of connection.
■ Coils are A.R.I. certified for system application with variety
of Rheem outdoor units.
■ Condensate drain pan is constructed of high grade, heat
resistant, corrosion free thermal-set material.
■ Compatible with Germicidal Light System (UV resistant)
■ Bi-Directional airflow eliminates the need to switch any
internal components from horizontal left to right.
■ Unique drain pan design maximizes application flexibility
and condensate removal.
■ Universal Duct Flanges are included with all coil models.

Accessories
• PLENUM ADAPTER ACCESSORY
RXBA-AE
This plenum adapter accessory is for use with the 24
1
/2" wide
cased indoor cooling and heat pump coils. This allows a 24
1
/2"
wide cased coil to be installed on a 28" wide oil furnace. This is a
field-installed accessory only.
• RXBA-AC (Upflow/Horizontal)
These plenum adapter accessories are for use when a cooling
coil is matched with a gas furnace of one smaller size.
• HORIZONTAL ADAPTER KIT RXHH (See Figure 2)
This horizontal adapter kit is used to convert a upflow or downflow
coil for a horizontal application. See Table 4 to order the proper
horizontal adapter kit.
*Note: The horizontal adapter kit cannot be used for RCFA/RCFL-
AU****BC applications. It can only be used on RCFA/RCFL-AU****AC
applications and for RCFA/RCFL-HU****AC applications.
