■
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 mecha-
nism.
The sealed
switch prevents
infiltration of
insects and dust. A minimal switching arc,
by the optical control, offers greater relia-
bility. The latching mechanism consumes
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 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
enables the oil 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 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 automo-
tive fuses can be utilized instead of replacing the entire
control board.
STANDARD FEATURES
RAPL- JEZ/RANL- JEZ Condensing Units
1.
This unit contains a special scroll compressor that is
designed specifically to operate with R-410A refrigerants
and polyolester (POE) oils. The 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.

FEATURES & BENEFITS OF THE
COMFORT CONTROL SYSTEM
™
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
compressor also has low start
torque, eliminating start problems
in the field. And its unique design
enables the RAPL- JEZ and
RANL- JEZ condensing units to
perform efficiently, quietly and
dependably.
All controls and compressor
are accessible for servicing by
removal of the service panel.
