XVIII. BLOWER MOTOR SPEED TAPS
Note: These instructions to be used in conjunction with airflow tables.
After determining necessary CFM and speed tap, follow the steps below to change
speeds.
Units with PSC Blower Motors:
1. Remove blower access panel.
2. Locate wire terminals on the motor. All wires to a PSC motor are high voltage.
The wire connected to the L (low), M (medium), or H (high) terminal determines
the motor speed. Adjust blower speed by moving wire between these speed
terminals. This speed will apply in both heating and cooling modes (they are not
individually selectable). Wires to numbered terminals should not be moved.
3. Replace blower access panel.
Units with X-13 Motors
1. Remove blower access panel.
2. Locate wire terminals on the motor. Numbered terminals are 24V blower taps
(See airflow tables for corresponding speed). The C terminal is 24V common. L,
N, and G terminals are high voltage and must remain unchanged.
3. Cooling speed can be adjusted by moving appropriate wire between taps at the
blower (Do not connect wires to unspecified speed taps).
4. Replace blower access panel.
