12.6.2 Selecting Speed Taps 6-9 (Not applicable to 

AMST60DU1400**)

When selecting speed taps 6-9, move the Black (BK) 

jumper, jumping T1 to any of terminal block locations T2 - 

T5. This will shift the motor to the 6-9 taps when the Purple 

(PU) lead from the blower relay is placed on the same tap 

as the Black (BK) jumper. See Table 13.

12.6.3 AMST60DU1400** (ONLY)

For high static applications, no speed tap or airflow 

modifications should be made from the factory settings. To 

obtain T1 airflow for low static applications, the Purple (PU) 

jumper between Y1 and T3 should be removed. See Table 

14.
