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.
■
Features a ten-year conditional unit replacement 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 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
feature the Genteq™ 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.
STANDARD FEATURES
RASL- JEZ 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 RASL- JEZ has a 10-year limited parts warranty, plus a
10-year conditional unit replacement warranty. Refer to the
General Terms of Limited Warranty for more details.
14. Hard Start Kits—Standard on all JEZ models.

™
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.
