AIRFLOW CAPACITIES
600-2000 CFM
[218-944 L/s]

Rheem®Indoor Coils are designed for use with Rheem out­door units and are available in upflow, downflow and hori­zontal configurations. All configurations are convertible to
any of the other airflow possibilities.

The MultiFlex

®

coils provide capacities ranging from 18,000

to 60,000 BTUH [5.27 to 17.58 kW].
The patented single-row, single-coil pleated concept results

in extremely low pressure drops and corresponding easy
cleaning.

Front refrigerant and drain connection add to ease of
installation. Coils can be field modified for left side refriger­ant connections and side connections on some models.
Double stacked coils are side refrigerant connect only with
front condensate.

Engineering Features

■ Constructed of enhanced aluminum fins bonded to inner

grooved copper tubing.

■ Coils have sweat fitting refrigerant connections.

■ Primary condensate drain connections are

3

/4" [19 mm]

F.N.P.T.

■ Coils are A.R.I. certified for system application with a wide

variety of Rheem outdoor units.

■ Condensate drain pan is constructed of a high grade, heat

resistant, corrosion free polymer material.

■ Double-wall construction offers sturdiness along with

dead air space insulation and sound attenuation.

■ Internally checked TX valves are used on high efficiency

heat pump coils for quieter refrigerant metering.

*Foam Tape

Foam tape is factory installed on the sides of the vertical drain pan if the coil is provided in a coil casing. Foam tape is
shipped loose with uncased coils.

If uncased coil is installed vertical in a coil casing or air handler, install the foam tape on the sides of the vertical drain pan.

If installed horizontal, DO NOT install foam tape on the side of the vertical drain pan that fits into the horizontal drain pan.
Remove foam tape, if already attached, from the side of the vertical drain pan that fits into the horizontal drain pan.

If coil, vertical or horizontal, is installed in coil casing or air handler with optional “Florida Insulation,” DO NOT install foam
tape on either side of the vertical drain pan.

ACCESSORIES (continued)

INTERNAL COUPLER ACCESSORY RXBA-AA
AND RXBA-AB

This internal coupler accessory is for installation in cased indoor
cooling and heat pump coils. This allows a nominal size coil to
be installed in the next larger size casing to be used on a gas or
oil furnace. NOTE: This accessory is for installation in coil

casings to fit gas or oil furnaces only—this accessory must
not be used on electric furnaces or heat pump air handlers.
The RXBA-AA can be ordered factory installed by both des­ignating the next size larger casing width and by designat­ing a “with adapter” (B) in the coil model number.

PLENUM ADAPTER ACCESSORY RXBA-AC
AND RXBA-AD

This plenum adapter accessory is for installation on cased
indoor cooling and heat pump coils. This allows a nominal size

cased coil to be installed on the next smaller size gas or oil fur­nace. NOTE: This accessory is for installation on coil cas-

ings to fit gas or oil furnaces only—this accessory must not
be used on electric furnaces or heat pump air handlers.The
RXBA-AC (Upflow Only) can be ordered factory installed by
designation as “with adapter” (B) in the coil model number.
