UNIT FEATURES & BENEFITS—RRKA- SERIES
These quality features are included in the Rheem®
Gas Heat/Electric Cooling Package Unit

UNIT FEATURES & BENEFITS—RRKA- SERIES
1. All models feature Copeland®Scroll®compressors for maxi-
mum efficiency and quiet operation.
2. Louvered condenser compartment for protecting the coil
against yard hazards and/or weather extremes.
3. One-piece top with a deep flange to help keep water out of
the unit.
4. Supply and return air openings feature a one-inch tall flange
to prevent water migration into the ductwork.
5. Access panels have “weep holes” and channels to further
help manage water run-off.
6. Side and down discharge options available on all models.
7. Easily accessible blower section complete with slide-out
blower. All units feature a system matched MultiFlex®coil
with low static pressure drop and excellent cooling capaci-
ties.
8. Refrigerant connections are conveniently located for easy
service diagnostics.
9. Condenser and evaporator coils feature enhanced fins for
better heat transfer and rifled copper tubing for greater
efficiency.
10. Inside the easily accessible furnace compartment is the draft
inducer motor. This motor is specially designed for quiet
reliable operation. In addition to the draft inducer motor, the
in-shot gas burners and manifold efficiently regulate the flow
of gas for combustion. These new gas/electric units also
feature direct-spark ignition and remote flame sensors for
added reliability and efficiency.
11. All units feature an internal trap on the condensate line elimi-
nating the need for installing an on-site external trap.
12. Easily accessible control box.
13. Single point wiring makes installation even easier.
14. Our gas/electric package units feature a tubular heat
exchanger design. Tubular heat exchangers are more effi-
cient and durable than older-style clamshell heat exchang-
ers. The heat exchanger is backed by a 10 year limited
warranty.

NOTES:
1. Cooling Performance is rated at 95° F ambient, 80° F entering dry bulb, 67° F entering wet bulb. Gross capacity does
not include the effect of fan motor heat. ARI capacity is net and includes the effect of fan motor heat. Units are suitable
for operation to 20% of nominal cfm. Units are certified in accordance with the Unitary Air Conditioner Equipment
certification program, which is based on ARI Standard 210/240 or 360.
2. EER and/or SEER are rated at ARI conditions and in accordance with DOE test procedures.
3. Heating Performance limit settings and rating data were established and approved under laboratory test conditions
using American National Standard Institute standards. Ratings shown are for elevations up to 2000 feet. For elevations
above 2000 feet, ratings should be reduced at the rate of 4% for each 1000 feet above sea level.
4. AFUE is rated in accordance with DOE test procedures.
5. Outdoor Sound Rating shown is tested in accordance with ARI Standard 270.

NOTE: The location of the combination supply and return diffuser should
not exceed 10 feet [3.05 m] above the floor level for units @ 1000 CFM
[472 L/s] or less and 12 [3.66 m] to 14 feet [4.27 m] above the floor level
for units with CFM greater than 1000 [472 L/s]. If the diffuser is installed
with a greater distance than recommended above, the supply air may
become stratified above the required comfort area causing uncomforta-
ble conditions.

Designed to convert a side by side or an over and under arrange-
ment into a concentric distribution of air. The diffuser is flush
mounted, completely insulated, assembled, and internally baffled
to provide four way supply air distribution with a center return. To
make the assembly complete and ready to fit into a 2' [0.61 m] x
4' [1.22 m] suspended ceiling grid, the diffuser includes
adjustable supply louvers, hanging rings, anti-sweat gasket, and
round flanges for use with flexible ducts.

INFORMATION (INCHES W.C. [kPa])
NOTE: The location of the combination supply and return diffuser should
not exceed 10 feet [3.05 m] above the floor level for units @ 1000 CFM
[472 L/s] or less and 12 [3.66 m] to 14 feet [4.27 m] above the floor level
for units with CFM greater than 1000 [472 L/s]. If the diffuser is installed
with a greater distance than recommended above, the supply air may
become stratified above the required comfort area causing uncomforta-
ble conditions.
*If a particular unit is to be converted to operate on LP (propane) for elevations above 2000 ft. [609.6 m] in Canada, the existing Natural Gas to LP Conversion Kits for the
subject models already contain the necessary orifices and instructions to de-rate the input for 2000-4500 ft. [609.6-1371.6 m] Canadian applications.

RRKA- Series
RXRE-CAA30 (3 Position)
Provided with enthalpy control, and
mixed air sensor. Settings include
fully open, fully closed and adjustable
mid point.
RXRD-CAM10 (Fully Modulating)
Provided with enthalpy control, mixed
air sensor and minimum position poten-
tiometer for proportioning (modulating)
the amount of fresh air.
NOTE: See economizer installation instruc-
tions for correct filter access door.
RXRF-FAA1 (Fixed - 0-35%)
The 0-35% manual outside Air Damper is designed to replace the
unit return air duct cover. No drilling or damper assembly is
required. The amount of outside air (0-35%) is controlled by sim-
ply adjusting the side damper.
RXRF-FAB1 (Motorized - 0-35%)
The 0-35% motorized outside Air Damper is designed to replace
the unit return air duct cover. No drilling or damper assembly is
required. The control motor opens the adjustable slide damper
when the unit blower motor is energized.
