The Rheem Prestige Series®High Efficiency Two-Stage RASLJEZ 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 RASL- JEZ Condensing
Units are the result of an ongoing development program for
improved efficiencies. With system SEER’s ranging to 18.50,
these units continue a tradition of high efficiency.
■ The Comfort Control System
™
provides on-board diagnostics
and fault history for condensing units with single-phase compressors by detecting system and electrical problems without
adding sensors. It can also communicate “fault codes” to
enabled “L terminal” thermostats. The integrated diagnostics
with Active Protection
™
prevents compressor operation when
potentially harmful conditions are detected.
■
7-Segment LED Display is exclusive only to Rheem products.
The information-display quickly and accurately shows technicians the source of malfunctions.
■
Ten-year conditional unit replacement warranty.
■ Reliable Two-Stage Scroll™ Compressor for precise tempera-
ture control providing ultimate comfort.
■ Comfort Alert™ Diagnostics comes installed in each Rheem
Prestige Series model.
■ 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.
■ Air is discharged upward away from bushes and shrubs. The
discharge pattern of the top grille provides minimum air restriction, resulting in quiet fan operation.
■ Exclusive Combination Grille/Motor Mount secures the motor to
the underside of the discharge grille. The grille protects the
motor windings and bearings from rain and snow.
■ For quiet operation and improved efficiency, the 3 ton model fea-
ture the GE
®
ECM two-speed 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.
■ On-demand dehumidification terminal, when matched with a
Prestige Series Air Handler or premium ECM Gas Furnace products, adjusts airflow to help control humidity for unsurpassed
comfort in the cooling mode.

The Rheem exclusive 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, high
& low voltage monitoring 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. With the high and low voltage
monitoring feature, the control
provides alerts for out-of-range conditions. 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.

2-STAGE SCROLL 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 RASL- JEZ
condensing unit to perform
efficiently, quietly and reliably.
All controls and compressor
are accessible for servicing by
removal of the service panel.
