2 Rheem Heating, Cooling and Water Heating
■
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 thermo-
stat 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 pressureswitch 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
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
RPNL- JEZ Heat Pump Outdoor 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. Enhanced Compressor Protection—Features an enhanced
defrost control, auto-reset high pressure control, and auto-reset
low pressure control to provide compressor protection under
abnormally high head pressure conditions (outdoor fan failure,
restriction, dirty coil, etc.) or abnormally low suction pressure conditions (restrictions, TEV failure, loss of charge, indoor blower failure,
etc.) while eliminating nuisance tripping sometimes experienced with
conventional control systems.
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
wrap-around louvered grille protects the coil from damage.
6. Enhanced compressor sound blanket is standard.
7. Demand Defrost Control—Provides complete defrost when defrost
is required.
8. Non-Cycling Reversing Valve—Eliminates discharge noises on
each heating cycle.
9. Hot Gas Muffler—Reduces noise in heating cycle.
10. Bi-Directional Filter Drier—Standard on RPNL- JEZ models
(shipped – not installed).
11. Service valves are standard on all models.
12. Refrigerant Metering—TEV accurately meters refrigerant into
indoor and outdoor coils.
13. Copper tube—aluminum fin coils are used on all models.
14. The control box is located in the top corner of the cabinet providing
for easy access through a service panel.
15. Service valves are standard on all models.
16. Field connections for power and control wiring are kept separate.
17. Every unit is factory charged and run-tested.
18. Separate compressor compartment for easy service access.
19. Drawn, painted basepan for extra corrosion resistance and sound
reduction.
20. The RPNL- JEZ has a 10 year limited compressor warranty, plus a
5 year conditional unit replacement warranty. See General Terms of
Limited Warranty for more details.
21. Hard Start Kits—Standard on all JEZ models.
22. Control Box Cover.
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 RPNL- JEZ Heat Pump to
perform efficiently, quietly and dependably.
