8 Airflow Performance Data Airflow Performance Airflow performance data is based on cooling performance with a coil and no filter in place. 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. tab 1 is for continuous fan. tab 2 (low static) and tab (high static) are for lower tonnage. tab (low static) and tab (high static) are for higher tonnage. Constant Torque air handlers are always shipped from factory at tab, except for -82, which is set at tab. For instance, (-)H1T-HM217JA is always shipped at high static 2-ton airflow ( tab ). To change to 1.-ton airflow, move the blue wire to tab 2 or on the Constant Torque motor. The low static tab 2 (lower tonnage) and (higher tonnage) are used for external static below 0." WC. The high static tab (lower tonnage) and (higher tonnage) are used for external static exceeding 0." WC. Move the blue wire to the appropriate tab as required by the application needs. The airflow for continuous fan ( tab 1) is always set at 0% of the 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

No electrical heating elements are permitted to be used with A voltage (11V) air handler. 9.0/12.0 / MULTIPLE CKT 1 2.0/ /2 0/ 9.0/12.0 / MULTIPLE CKT 2 2.0/ /7 /0 21.6/28.8 / SINGLE 60.0/ /9 90/ /1. / MULTIPLE CKT 1 0.0/.7.6 /0 /0 10.8/1. / MULTIPLE CKT 2 0.0/.7 0 8/ 0/ J voltage (208/20V) single phase air handler is designed to be used with single or three phase 208/20V volt electric heaters. In the case of connecting phase power to air handler terminal block without the heater, bring only two leads to terminal block, cap, insulate and fully secure the third lead. Do not use 80V electrical heaters on 208/20V air handlers. If the kit is listed under both single and multiple circuits, the kit is shipped from factory as multiple circuits. For single phase application, Jumper bar kit RXBJ-A21 and RXBJ-A1 can be used to convert multiple circuits to a single supply circuit. Refer to Accessory Section for details. 2
