* Dryer performance is optimized for 2-phase, 240 V AC service. If complaint is made regarding dryer performance and the L1 to L2 voltage
is ~208 V AC, dryer may be connected to a 3-phase service with reduced wattage that will decrease dryer performance. Also check the
Customer Focused Dryness Level setting (see page 19).

Motor On to 200).
Heater On • If Gas: Display "9as" for gas since L2
does not exist.
Motor On
L2 continues to be displayed.
Heater On
Motor On Once L1 is calculated, L1 to L2 is
Heater On/Off immediately calculated in the CCU.
• L1 voltage should be 120 V AC ± 10%.
• L2 voltage should be 120 V AC ± 10%,
Motor On
or "9as" if gas dryer.
Heater On/Off
• L1 to L2 voltage should be 240* V AC
± 10%, or "9as" if gas dryer.
Motor On The display will count down the final 15
Heater On/Off seconds of the AirFlow detection routine.
When the airflow routine is complete,
Motor Off the seven-segment display will show
Heater Off airflow result (0=BAD, 1=GOOD,
