Maximum Overcurrent Protection

{Motors are designed for satisfactory operation within 10% of normal voltage shown. Voltages should not exceed the limits shown in the Voltage Limits column.

NOTES:

1.Minimum circuit amps (MCA) and MOCP values are calcu- lated in accordance with The NEC. Article 440.

2.Motor FLA values are established in accordance with Under- writers’ Laboratories (UL). Standard 1995.

3.Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the formula in the example (see column to the right) to determine the percentage of volt- age imbalance.

4.Installation with Accessory Electric Heaters

Size the Field Power Wiring between the heater TB1 and the 40RU indoor fan motor per NEC Article 430--- 28 (1) or (2) (depends on length of conduit between heater enclosure and 40RU power entry location). Install wires in field--- installed conduit.

Example: Supply voltage is 230-3-60

% Voltage Imbalance = 100 x

Determine maximum deviation from average voltage. (AB) 397 – 393 = 4 v

(BC) 403 – 397 = 6 v (AC) 397 – 396 = 1 v Maximum deviation is 4 v.

Determine percent of voltage imbalance.

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

542J specifications

Bryant 542J is a high-efficiency gas furnace that stands out for its reliability and advanced heating technologies. Designed to deliver consistent warmth and comfort in residential settings, it combines innovative engineering with energy-efficient features.

One of the key characteristics of the Bryant 542J is its two-stage heating capability. This means that the furnace can adjust its heat output according to the heating demands of your home. During milder weather, it operates at a lower stage, consuming less energy while still maintaining a comfortable environment. When the temperatures drop, the furnace shifts to its higher capacity, providing the necessary warmth efficiently. This not only enhances comfort but also contributes to lower energy bills.

In addition to its two-stage operation, the Bryant 542J also incorporates a variable-speed blower motor. This technology allows the furnace to adjust the airflow depending on the heating requirements, ensuring an even distribution of warm air throughout the home. The variable-speed blower also operates more quietly than conventional fixed-speed motors, creating a serene indoor environment.

Energy efficiency is a hallmark of the Bryant 542J, boasting an Annual Fuel Utilization Efficiency (AFUE) rating of up to 96.5%. This impressive rating means that a significant portion of the energy consumed is effectively converted into usable heat, resulting in substantial savings on heating costs over time. Furthermore, the furnace is equipped with a sealed combustion system that draws air from outside the home, minimizing energy waste and improving indoor air quality.

Diagnostic features are another highlight of the Bryant 542J, which come equipped with SmartEvap technology. This allows the unit to self-diagnose potential issues, providing homeowners with peace of mind and simplifying maintenance procedures.

Durability is also a key feature of the Bryant 542J. It is constructed with high-quality materials designed to withstand harsh winter conditions, ensuring a long lifespan and reliable performance. Its compact design also allows for flexible installation, making it suitable for various residential layouts.

In summary, the Bryant 542J is more than just a gas furnace; it is a sophisticated heating solution that combines efficiency, comfort, and reliability. With features such as two-stage heating, a variable-speed blower, high AFUE ratings, and advanced diagnostics, it is an excellent choice for homeowners seeking an efficient and effective heating system.
