The Rheem Prestige Series™ High Efficiency Two-Stage RARLJEC Condensing Unit was designed with performance in mind.
These units offer comfort, energy conservation and dependability
for single, multi-family and light commercial applications. The
Rheem Prestige Series™ Two-Stage RARL- JEC Condensing
Units are the result of an ongoing development program for
improved efficiencies. With system SEER’s as high as 17 SEER/
13 EER, these units continue a tradition of delivering high efficiency.
■ Industry’s lowest profile design: 33" maximum height
■ The Comfort Control
2
System™ provides over 32+ on-board
diagnostics and fault history codes for condensing units with
single-phase compressors by detecting system and electrical
problems. The integrated diagnostics with Active Protection™
prevents compressor operation when potentially harmful conditions are detected. Sends “Call for Service” alert notification to
the thermostat to alert the homeowner of required service.
■
Serial Communication Enhanced – When installed with a Serial
Communicating Air Handler (RHPL/RHPN-HM****JC) and user
interface control (RHC-TST501CMMS) Series 500 thermostat
this unit offers 4 or 2 wire installation, auto-configuration, and
diagnostic messaging with full communicating capability.
■
Legacy Enabled – Unit can be conventionally wired using
24VAC with non-communicating Rheem Prestige air-handlers or
furnaces with non-communicating thermostat.
■
Features a 10-year conditional unit replacement warranty and
10-year parts warranty when properly installed with a new
Rheem air handler or Rheem indoor coil with a Rheem gas furnace. See product warranty card for additional information.
■
Reliable Two-Stage operation for precise temperature control with
On-Demand dehumidification feature. When matched with ECM
gas furnace or air-handler, the system adjusts airflow to help control humidity for unsurpassed comfort in the cooling mode.
■ All controls are accessible by removing one service panel.
Removable top grille provides access to the condenser fan
motor and condenser coil.
■ Attractive, louvered wrap-around jacket protects the coil from
yard hazards and weather extremes. Top grille is steel reinforced for extra strength. Cabinet is powder painted for all
weather protection.
■ For quiet operation and improved efficiency, models feature an
ECM two-speed condenser fan motor with a 3-blade outdoor fan.
■ All models meet or exceed a 1000-hour salt spray test per ASTM
B117 Standard Practice for Operating Salt Spray Testing
Apparatus.

The Rheem exclusive Dual 7-Segment LED Display easily
shows system operating status codes
and diagnostic codes.
■
A Sealed Switch replaces the standard
contactor and
features optical
control and
latching mechanism. The sealed
switch prevents
infiltration of
insects and dust. A minimal switching arc,
by the optical control, offers greater reliability. The latching mechanism consumes
less power while reducing chatter.
■
The Status Indication and System Diagnostics feature thermostat communication capability, built-in diagnostics, current sensing and high & low pressure switch monitoring. The
thermostat communication capability alerts the homeowner to
any necessary service requirements.
Faster, more accurate service is provided by the built-in diagnostics, by
providing the HVAC professional with
dependable information. In addition,
high and low pressure-switch monitoring prevents the system from operating outside of its normal parameters.
■
The fault recall feature will allow for the last six fault-codes
to be displayed, and will retain these codes even if power
failure occurs.
■
Built-in short-cycle protection allows the compressor to
restart easily without oil removal.
■
A 30-second minimum run-time for every compressor call
allows the oil to return to the compressor.
■
Active Protection monitors the system to prevent nuisance
lockouts and prevents compressor operation when potentially harmful conditions are detected.
■
The compressor and fan are
controlled independently,
which reduces the starting load
and light dimming.
■
A manual push-button is
offered to operate the compressor and fan for 5 seconds to
allow for an operation check.
■
In order to save time and
money, replacement automotive fuses can be utilized instead of replacing the entire
control board.
STANDARD FEATURES
RARL- JEC Condensing Units
1. Scroll compressor is hermetically sealed and incorporates
internal high temperature motor overload protection, and
durable insulation on the motor windings. It is externally
mounted on rubber grommets to reduce vibration and noise.
2. Compressors have an internal pressure relief assembly to
protect against excessive pressure differential.
3. All refrigerant connections are on the exterior of the unit,
located close to the ground for neat appearing installations.
4. Cabinet is constructed of powder painted galvanized
steel. The full wrap-around louvered grille protects the coil
from damage.
5. Sound Blanket-enhanced compressor sound blanket is
standard.
6. Copper tube—aluminum fin coils are used on all models.
7. The control box is located in the top corner of the cabinet
providing for easy access through a service panel.
8. Service valves are standard on all models.
9. Field connections for power and control wiring are kept
separate.
10. Every unit is factory charged and run-tested.
11. Separate compressor compartment for easy service access.
12. Drawn, painted base pan for extra corrosion resistance and
sound reduction.
13. The RARL- JEC has a 10-year limited parts warranty, plus a
10-year conditional unit replacement warranty. Refer to the
General Terms of Limited Warranty for details.
14. Hard Start Kits—Standard on all JEC models.
15. Control Box Cover.
16. The RARL- JEC is shipped with a liquid line filter drier, and
also features factory-installed low and high pressure
controls, and time delay control.

3-blade outdoor fan. The 5 ton model features the GE
®
ECM
two-speed motor with a 3-blade outdoor fan.
FEATURES & BENEFITS OF THE COMFORT CONTROL SYSTEM
™
SCROLL TWO-STAGE
ULTRA TECH
™
COMPRESSOR
The 2-Stage Scroll UltraTech™ compressor is the key to
efficiency for this Rheem model. It’s the latest in high-efficiency
compressor technology. The advanced scroll compressor offers
low noise and vibration
characteristics and features
tolerance to liquid refrigerant and
system contamination. The Scroll
UltraTech™ also has low start
torque, eliminating start problems
in the field. And its unique design
enables the RARL- JEC
condensing unit to perform
efficiently, quietly and reliably.
All controls and compressor
are accessible for servicing by
removal of the service panel.

■
Low Ambient Control—Cycles outdoor fan to maintain
adequate condensing pressures assuring liquid refrigerant
flow to the coil. Allows indoor cooling with outdoor
temperatures down to 0°F [–17.8°C]. (Model No. RXAD-A08)
It is recommended that this control be installed in units
to be operated at outdoor ambient temperatures under
45°F [7°C].
■
Thermostats—
■
Compressor Crankcase Heater (CCH)—While scroll
compressors usually do not require crankcase heaters, there
are instances when a heater should be added. Refrigerant
migration during the off cycle can result in a noisy start up.
Add a crankcase heater to minimize refrigeration migration,
and to hep eliminate any start up noise or bearing “wash out.”
