The Rheem Prestige Series™ High Efficiency Two-Stage RPRLJEC Heat Pump can provide year-round heating and cooling comfort. The Rheem RHPL air-handler, equipped with auxiliary heating elements for supplementary heat was designed especially for
use with the Prestige Series™ heat pump. Together they deliver 3
stages of heat and 2 stages of cooling for precise temperature
control and optimal energy efficiency.
■ Industry’s lowest profile design: 33" maximum height
■ The Comfort Control
2
System™ provides over 37+ 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-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 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 and
On-Demand dehumidification. 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 allweather 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.
■ Dual Fuel capable with select thermostats.

TWO-STAGE SCROLL
®
COMPRESSOR
The scroll 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
also has low start torque,
eliminating start problems in the
field. And its unique design
enables the RPRL- JEC Heat
Pump to perform efficiently,
quietly and reliably. All models
have a 10-year compressor
warranty as standard.
STANDARD FEATURES
RPRL- JEC Heat Pumps
1. 2-stage operation in both cooling and heating mode.
2. 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.
3. Compressors have an internal pressure relief assembly to
protect against excessive pressure differential.
4. All refrigerant connections are on the exterior of the unit,
located close to the ground for neat appearing installations.
5. Cabinet is constructed of powder painted galvanized
steel. The full wraparound louvered grille protects the coil
from damage.
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 RPRL- JEC has a 10 year limited parts warranty, plus a
10 year conditional unit replacement warranty. See the
General Terms of Limited Warranty for more details.
14. Hard Start Kits—Standard on all JEC models.
15. Enhanced compressor sound wrap is standard.
16. Control Box Cover.
17. The RPRL- JEC is shipped with a liquid line filter drier,
(not-installed).
18. The RPRL- JEC features factory-installed auto-reset low
and high pressure controls.
FEATURES & BENEFITS OF THE COMFORT CONTROL2SYSTEM
™
■
The Rheem Exclusive Dual 7 Segment LED Display easily
shows system status codes and conditions.
■
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 switch monitoring. The thermo-
stat communication capability alerts the homeowner of any
necessary service requirements.
Faster, more accurate service is provided with 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 when damage could occur.
■
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 removing the oil from the compressor.
■
A 30-second minimum run-time for every compressor call
allows the oil to return to the compressor.
■
Active Protection prevents the compressor from operating if
damage could occur.
■
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.
All controls and compressor
are accessible for servicing by
removal of the service panel.

For all season home comfort, performance and energy conservation, choose a Rheem Prestige Series™ RPRL- JEC Series Heat
Pump and with an RHPL-HM***JC or RHPL-HM**JA Air Handler.
More than a reverse cycle air conditioner, it’s a specially designed combination Winter/Summer comfort system using an indoor coil for
heating and cooling.
To choose an RHPL-HM***JC or RHPL-HM**JA Air Handler designed for use with the RPRL- JEC Heat Pump, refer to the Performance
Data Tables and/or the air handler specification sheet.
Rheem Heat Pump System
NOTE: Requires “3 Heat/2 Cool” thermostat for Maximum Comfort.
IMPORTANT:
The Comfort Control2System™ requires a communicating
RPRL-JEC Heat Pump, the RHPL-HM***JC Air Handler and
the 500-Series Thermostat.
