Fig. 28—Burner Rack Removed

I. Condenser Fan

CAUTION: Keep the condenser fan free from all ob- structions to ensure proper cooling operation. Never place articles on top of the unit. Damage to unit may result.

1.Remove 6 screws holding condenser grille and motor to top cover.

2.Turn motor/grille assembly upside down on top cover to expose the fan blade.

3.Inspect the fan blades for cracks or bends.

4.If fan needs to be removed, loosen the setscrew and slide the fan off the motor shaft.

5.When replacing fan blade, position blade so that the hub is 1/8 in. away from the motor end (1/8 in. of motor shaft will be visible).

6.Ensure that setscrew engages the flat area on the motor shaft when tightening.

7.Replace grille.

J. Electrical Controls and Wiring

Inspect and check the electrical controls and wiring annually. Be sure to turn off the gas supply, and then the electrical power to the unit.

Remove access panel to locate all the electrical controls and wiring. Check all electrical connections for tightness. Tighten all screw connections. If any smokey or burned connections are noticed, disassemble the connection, clean all the parts, restrip the wire end and reassemble the connection properly and securely.

After inspecting the electrical controls and wiring, replace the access panel. Start the unit, and observe at least one complete heating cycle and one complete cooling cycle to ensure proper operation. If discrepancies are observed in either or both operating cycles, or if a suspected malfunction has occurred, check each electrical component with the proper electrical instrumentation. Refer to the unit wiring label when making these checkouts.

NOTE: Refer to the heating and/or cooling sequence of operation in this publication as an aid in determining proper control operation.

K. Refrigerant Circuit

Inspect all refrigerant tubing connections and the unit base for oil accumulations annually. Detecting oil generally indicates a refrig- erant leak.

If oil is detected or if low cooling performance is suspected, leak-test all refrigerant tubing using an electronic leak-detector, halide torch, or liquid-soap solution. If a refrigerant leak is detected, refer to Check for Refrigerant Leaks section on page 13.

If no refrigerant leaks are found and low cooling performance is suspected, refer to Checking and Adjusting Refrigerant Charge section in this document.

L. Evaporator Airflow

The heating and/or cooling air-flow does not require checking unless improper performance is suspected. If a problem exists, be sure that all supply- and return-air grilles are open and free from obstructions, and that the air filter is clean. When necessary, refer to Indoor Airflow and Airflow Adjustments section in this docu- ment to check the system airflow.

M. Metering Device–Check-Flo-Rater® Piston

This metering device is a fixed orifice and is contained in the brass hex-body in the liquid line.

N. Pressure Switches

Pressure switches are protective devices wired into control circuit (low voltage). They shut off compressor if abnormally high or low pressures are present in the refrigeration circuit. These pressure switches are specifically designed to operate with Puron (R-410A) systems. R-22 pressure switches must not be used as replacements for the Puron (R-410A) air conditioner.

LOSS OF CHARGE/LOW-PRESSURE SWITCH (air conditioner only)

This switch is located on the liquid line and protects against low suction pressures caused by such events as loss of charge, low airflow across indoor coil, dirty filters, etc. It opens on a pressure drop at about 20 psig. If system pressure is above this, switch should be closed.

To check switch:

1.Turn off gas and then all power to unit.

2.Disconnect leads on switch.

3.Apply ohmmeter leads across switch. You should have continuity on a good switch.

NOTE: Because these switches are attached to refrigeration system under pressure, it is not advisable to remove this device for troubleshooting unless you are reasonably certain that a problem exists. If switch must be removed, remove and recover all system charge so that pressure gauges read 0 psi. Never open system without breaking vacuum with dry nitrogen.

HIGH-PRESSURE SWITCH—The high-pressure switch is lo- cated in the discharge line and protects against excessive con- denser coil pressure. It opens at 610 psig.

High pressure may be caused by a dirty condenser coil, failed fan motor, or condenser air recirculation.

To check switch:

1.Turn off gas and then all power to unit.

2.Disconnect leads on switch.

3.Apply ohmmeter leads across switch. You should have continuity on a good switch.

O.Copeland Scroll Compressor (Puron Refrigerant

The compressor used in this product is specifically designed to operate with Puron (R-410A) refrigerant and cannot be inter- changed.

583B specifications

The Bryant 583B is an advanced, high-efficiency gas furnace designed to provide exceptional heating performance and reliability. With a focus on comfort and energy efficiency, this model stands out in the residential heating market.

One of the main features of the Bryant 583B is its impressive Annual Fuel Utilization Efficiency (AFUE) rating of up to 95%. This means that the furnace converts up to 95% of the fuel it consumes into usable heat. As a result, homeowners can expect lower energy bills and reduced environmental impact due to decreased carbon emissions.

The Bryant 583B is equipped with a modulating gas valve that allows for precise control of the heating output. This technology enables the furnace to adjust its running capacity based on the heating demands of your home. Instead of operating at a single, high setting, the furnace runs at the required level to maintain the desired temperature, delivering consistent comfort while maximizing efficiency.

Another noteworthy characteristic of the 583B is its two-stage operation. This feature allows the furnace to operate at a lower stage for mild weather, which reduces energy consumption and minimizes noise levels. During colder conditions, it can switch to a high stage for increased heating capacity. This dual approach not only enhances comfort but also prolongs the lifespan of the unit by reducing wear and tear.

In terms of construction, the Bryant 583B is built with durable materials and a robust cabinet, which ensures longevity and resilience over time. It also comes with a quiet operation feature, minimizing disturbances while maintaining a comfortable indoor environment.

The unit is compatible with Bryant's advanced communication technology, enabling seamless integration with smart thermostats. This addition allows homeowners to monitor and control their furnace remotely, optimizing energy usage even further.

In summary, the Bryant 583B furnishes an outstanding combination of efficiency, reliability, and user-friendly technologies. Its modulating gas valve, two-stage operation, and high AFUE rating collectively ensure that customers enjoy a comfortable home environment while significantly reducing energy costs. As energy-conscious choices become increasingly crucial, the Bryant 583B stands ready to meet the challenges of modern heating needs.
