The model number for the DURASTAR DRF2TA3624ASTNJN0F provides the following information:

The dimensions, weight, and other specifications for the DURASTAR DRF2TA3624ASTNJN0F are detailed below.

For optimal blower performance, the DURASTAR DRF2TA3624ASTNJN0F should be operated in the .3 [8 mm] to .7 inches [18 mm] W.C. external static range. The specific operating limits for the Model Cabinet Size 24 are as follows:

The airflow performance data for the DURASTAR DRF2TA3624ASTNJN0F (3 Tons model with a 10×8 1/2 Hp blower) at various external static pressures is listed below. This data is for dry delivery and includes filter and heaters.

The DURASTAR DRF2TA3624ASTNJN0F air handler has a 5-speed constant torque motor. The speed taps are used as follows:

• Speed tap 1: For continuous fan operation.

• Speed tap 2 (low static) and speed tap 3 (high static): For lower tonnage applications (1.5 or 2.5 tons).

• Speed tap 4 (low static) and speed tap 5 (high static): For higher tonnage applications (2.0 or 3.0 tons).

The unit is shipped from the factory set to speed tap 5. Use the low static speed tap (4) for external static pressures below 0.5″ WC. Use the high static speed tap (5) for external static pressures exceeding 0.5″ WC. To change the speed, move the blue wire to the appropriate speed tap on the motor terminal block as required by the application needs.

The airflow for the continuous fan (speed tap 1) is always set at 50% of the speed tap 4 airflow.

The electrical data for the blower motor only (no electric heat) on the DURASTAR DRF2TA3624ASTNJN0F is as follows:

*Blower motors are all single phase motors.

When installing a U.L. Listed original equipment manufacturer provided heater kit with the DURASTAR DRF2TA3624ASTNJN0F, refer to the following electrical data:
