F. Provide Safety Relief

A fusible plug is located on the compressor crankcase or in the liquid line. See Fig. 6. Do not cap this plug. If local code requires additional safety devices, install them as directed.

Head Pressure Control (541A180 only)

Fan cycling for head pressure control is a standard offering but is functional on the cooling cycle only. Number 2 fan cycles as a function of liquid pressure. Fan cycling pressure switch cycles the fan off at 160 ± 10 psig as pressure decreases and cycles back on at 255 ± 10 psig. Switch is auto- matically bypassed in heating cycle. Table 5 shows minimum outdoor air temperature for full cooling capacity.

G. Vapor Line Piping Procedure

Connect system vapor line to the vapor line stub on the out- door unit and the vapor stubs on the indoor unit. At the indoor unit, construct vapor piping branches as shown in Fig. 7 for good mixing of the refrigerant leaving the indoor coil during cooling. This will ensure proper TXV (thermo- static expansion valve) bulb sensing.

Where vapor line is exposed to outdoor air, line must be insu- lated. See Table 6 for insulation requirements.

*Recommended vapor line insulation for piping exposed to outdoor conditions to prevent loss of heating during heating cycle. When vapor line goes through interior spaces, insulation should be selected to pre- vent condensation on cooling cycle. Heating capacity should be reduced 1000 Btuh if over 35 ft of vapor line with 3/4 in. insulation is exposed to outdoor conditions.

541A, 575B, 575C specifications

The Bryant 575B, 541A, and 575C heating and cooling units are part of the renowned Bryant lineup, designed to provide efficient and reliable climate control solutions for residential and commercial spaces. These models are particularly celebrated for their impressive performance, innovative technologies, and user-friendly operations.

Starting with the Bryant 575B, this model is a high-efficiency air conditioner that boasts a SEER rating of up to 20.5. It utilizes a variable-speed compressor that adjusts its output based on the temperature needs of the home, leading to enhanced energy savings and consistent indoor comfort. The 575B is equipped with a steel cabinet that resists corrosion and damage while also minimizing noise levels during operation. Additionally, its environmentally friendly R-410A refrigerant helps to reduce the system's ecological footprint.

Moving on to the Bryant 541A, this unit is a formidable gas furnace known for its exceptional heating capabilities. With an AFUE (Annual Fuel Utilization Efficiency) rating of up to 97.5%, the 541A efficiently transforms fuel into heat, ensuring lower energy bills during cold months. It incorporates advanced technologies such as a two-stage gas valve and a variable-speed blower motor, allowing it to respond dynamically to the heating demands of the home. The insulated cabinet construction further enhances energy efficiency by preventing heat loss and increasing comfort.

Lastly, the Bryant 575C model is a versatile heat pump that offers both heating and cooling functionalities, ideal for regions with moderate heating and cooling needs. It features a SEER rating of up to 20 and an HSPF (Heating Season Performance Factor) rating of up to 10.5, making it an energy-efficient choice year-round. The 575C comes with a streamlined design that integrates a variable-speed compressor, which helps maintain precise temperatures and minimizes energy consumption. Additionally, its quiet operation is enhanced by sound insulation, providing a serene indoor environment.

All three models are designed with durability in mind, featuring robust construction materials that withstand the elements. They can be easily integrated with smart thermostats, providing homeowners with greater control over their energy use. With exceptional efficiency ratings, durable designs, and advanced features, the Bryant 575B, 541A, and 575C represent a perfect blend of comfort and cutting-edge technology. Whether for heating or cooling, these units deliver outstanding performance to meet the needs of today's energy-conscious consumers.
