Standard Features
RARL- 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 RARL- JEZ has a 10-year limited parts warranty, plus a

■
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 mecha-
nism.
The sealed
switch prevents
infiltration of
insects and dust. A minimal switching
arc, by the optical control, offers greater
reliability. The latching mechanism con-
sumes less power while reducing chatter.
■
The Status Indication and System Diagnostics feature ther-
mostat 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 infor-
mation. With the high and low voltage
monitoring feature, the control
provides alerts for out-of-range con-
ditions. In addition, high and low pressure-switch monitoring pre-
vents 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 poten-
tially 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 com-
pressor 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.
