!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Disconnect 115-v electrical power and install lockout tag before changing speed tap.

c.Adjust air temperature rise by adjusting blower speed. Increase blower speed to reduce temperature rise. Decrease blower speed to increase temperature rise.

d.Turn thermostat down below room temperature and remove blower access door.

e.To change motor speed selection for heating, remove blower motor lead from control HEAT terminal (See Fig. 25.) Select desired blower motor speed lead from one of the other terminals and relocate it to the HEAT terminal (See Table 12 for lead color identification).

Reconnect original lead to SPARE terminal.

g.When correct input rate and temperature rise is achieved, turn gas valve ON/OFF switch to OFF.

h.Remove manometer or similar device from gas valve.

i.Reinstall manifold pressure tap plug in gas valve.

!WARNING

FIRE HAZARD

Failure to follow this warning could result in personal injury, death and/or property damage.

Reinstall manifold pressure tap plug in gas valve to prevent gas leak.

j.Reinstall blower access door if removed.

k.Turn gas valve ON/OFF switch to ON.

!CAUTION

FURNACE OVERHEATING HAZARD

Failure to follow this caution may result in reduced furnace life.

Recheck temperature rise. It must be within limits specified on the rating plate. Recommended operation is at the midpoint of rise range or slightly above.

6.Set thermostat heat anticipator.

a.Mechanical thermostat - Set thermostat heat anticipat- or to match the amp. draw of the electrical components in the R-W circuit. Accurate amp. draw readings can be obtained at the wires normally connected to ther- mostat subbase terminals, R and W. The thermostat anticipator should NOT be in the circuit while measur- ing current. (1.) Remove thermostat from subbase or from wall. (2.) Connect an amp. meter as shown in Fig. 44 across the R and W subbase terminals or R and W wires at wall.

(3.) Record amp. draw across terminals when furnace is in heating and after blower starts.

(4.) Set heat anticipator on thermostat per thermostat instructions and install on subbase or wall.

b.Electronic thermostat: Set cycle rate for 4 cycles per hr.

7.Adjust blower off delay The blower off delay has 4 ad- justable settings from 90 sec to 180 sec. The blower off delay jumpers are located on the furnace control board. (See Fig. 25.) To change the blower off delay setting, move the jumper from one set of pins on the control to the pins used for the selected blower off delay. Factory off delay setting is 120 sec.

8.Set airflow CFM for cooling Select the desired blower motor speed lead for cooling airflow. See Table 5-Air De- livery-CFM (With Filter). See Table 12 for lead color identification.

310AAV specifications

The Bryant 310AAV and 310JAV are high-efficiency air conditioning and heating systems designed for residential and light commercial applications. These models embody Bryant's commitment to delivering reliable comfort solutions while prioritizing energy efficiency and performance.

One of the standout features of the Bryant 310AAV and 310JAV is their impressive Seasonal Energy Efficiency Ratio (SEER) ratings. The higher the SEER, the more efficient the unit is in using electricity to cool your space. The Bryant 310AAV boasts a SEER rating of up to 16, while the 310JAV offers a slightly lower rating. This efficiency translates into cost savings on monthly energy bills while ensuring indoor comfort throughout the year.

Both models utilize advanced technologies, including two-stage heating and cooling capabilities. This means that the systems can adjust their operation based on the heating or cooling needs of a space, providing optimal temperature control while reducing energy waste. The two-stage operation also contributes to quieter operation levels, making these units suitable for residential settings where noise is a concern.

The 310AAV and 310JAV are equipped with variable-speed compressors, which further enhance their efficiency and comfort levels. The variable-speed technology allows the system to operate at different speeds, ensuring consistent temperature management and reducing the frequency of on-and-off cycling. This leads to steadier indoor temperatures and improved humidity control.

In addition to their performance features, Bryant places a strong emphasis on durability and dependability. The units are constructed with high-quality materials that are designed to withstand various environmental conditions. Features such as a weather-resistant cabinet and an efficient coil design help protect the units from wear and tear, ensuring long-lasting performance.

The implementation of environmentally friendly refrigerant options is another characteristic that demonstrates Bryant's commitment to sustainability. Both the 310AAV and 310JAV utilize R-410A refrigerant, which has a lower environmental impact compared to older refrigerants, aligning with modern standards for eco-friendly HVAC systems.

Overall, the Bryant 310AAV and 310JAV represent a blend of efficiency, advanced technology, and durability.
