ADC AD-360X2 D. THERMOSTATS AND TEMPERATURE SENSOR

TO REPLACE DIRECT SPARK IGNITION (DSI) MODULE

1. Discontinue power to the dryer.

2. Remove the back guard.

3. Remove the wires connected to the terminal strip

at the bottom of the module.

4. Remove the four (4) nuts securing the module to

the mounting bracket.

5. Replace module by reversing process.

NOTE:Take note of where wires are for installing the new module.

D. THERMOSTATS AND TEMPERATURE SENSOR

TO REPLACE HI-LIMIT THERMOSTAT (290°)

This thermostat is an important safety device, serving as an added protection against failure of the airflow sail

switch to open in the event of a motor failure or reduced airflow condition.

IMPORTANT: UNDER NO CIRCUMSTANCES should the heat circuit safety devices ever be

disabled.

1. Discontinue power to the dryer.

2. Remove the two (2) hex head screws from the hi-limit switch. Then, the hi-limit will be removed from the

burner box. Remove the two (2) wires from the hi-limit.

3. Reverse procedure for installing new thermostat.
