208V/240V Airflow Performance Data—RF1T (X-13 (ECM) Motor)
Notes: X-13 motor speed changes.
All X-13 motors have 5 speed taps. Speed tap 1 is for continuous fan. Speed tap 2 (low static) and speed tap 3 (high static) are for lower tonnage. Speed tap 4 (low
static) and speed tap 5 (high static) are for higher tonnage.
X-13 air handlers are always shipped from factory at speed tap 5. To change to 1.5-ton or 2.5-ton airflow, move the blue wire to speed tap 2 or 3 on the
X-13 motor. The low static speed tap 2 (lower tonnage) and 4 (higher tonnage) are used for external static below 0.5" WC. The high static speed tap 3 (lower tonnage)
and 5 (higher tonnage) are used for external static exceeding 0.5" WC. Move the blue wire to the appropriate speed tap as required by the application needs.
• The airflow for continuous fan (speed tap 1) is 50% of the speed tap 4 airflow.
• The above airflow table lists the airflow information for air handlers with maximum heater allowed for each model.
