Select performance table for appropriate unit size, voltage and number of electric heaters to be used. Make sure external static applied to unit allows operation within the minimum and maximum limits shown in table below for both cooling and electric heat operation. For optimum blower performance, operate the unit in the. [8 mm] to.7 inches [18 mm] W.C. external static range. Units with coils should be applied with a minimum of.1 inch [ mm] W.C. external static range.

All Constant Torque motors have speed tabs. Speed tab 1 is for continuous fan. Speed tab (low static) and Speed tab (high static) are for lower tonnage. Speed tab (low static) and Speed tab (high static) are for higher tonnage. Constant Torque air handlers are always shipped from factory at Speed tab, except for -8, which is set at Speed tab. For instance, (-)H1T-HM17JA is always shipped at high static -ton airflow (Speed tab ). To change to 1.-ton airflow, move the blue wire to Speed tab or on the Constant Torque motor. The low static Speed tab (lower tonnage) and (higher tonnage) are used for external static below 0." WC. The high static Speed tab (lower tonnage) and (higher tonnage) are used for external static exceeding 0." WC. Move the blue wire to the appropriate Speed tab as required by the application needs. The airflow for continuous fan (Speed tab 1) is always set at 0% of the Speed tab. The above airflow table lists the airflow information for air handlers without heater and air handler with maximum heater allowed for each model. The following formula can be used to calculate the approximate airflow, if a smaller (N kw) than the maximum heater kit is installed. Approximate Airflow = Airflow without heater (Airflow without heater Airflow with maximum heater) x (N kw/maximum heater kw) 10 WeatherKing

Replace the cap on the black motor wire. Voltage change (08/0V motors): Move the orange lead to transformer 08V tap from 0V tap. Replace the wire cap on 0V tap. Unplug the purple motor wire off the transformer and plug in the yellow motor wire. Replace the cap on the purple motor wire. The above airflow table lists the airflow information for air handlers without heater and air handler with maximum heater allowed for each model.
