CAUTION: DO NOT LET THE IGNITOR/FLAME-PROBE ASSEMBLY TOUCH THE BURNER TUBES; OTHERWISE THE ENTIRE ASSEMBLY WILL SHORT OUT.

6)Direct Spark Ignition (DSI) 24 VAC Transformer

The DSI transformer is designed to step down the operating voltage of the dryer to 24 VAC. This operates the DSI module. This transformer, like ALL transformers is two (2) sided...

a)Primary Side...

This is the incoming voltage side - 208 VAC, 230/240 VAC, 380 VAC, 416 VAC, 480 VAC - of the transformer.

b)Secondary Side...

This is the step down side - 24 VAC - of the transformer. (If the dryer is above 240 VAC a secondary voltage of 240 VAC will also be present.)

WARNING: 208 VAC and 230/240 VAC ARE NOT THE SAME. ALL voltage connections should be checked and confirmed according to the foil data label provided with the individual dryer. Any damage done to dryer components due to improper voltage connections will automatically VOID THE WARRANTY.

IMPORTANT: The ADC Service Department must be contacted prior to any wiring changes or conversions, because depending on the changes or conversions required some parts might have to be added, deleted, or changed. When contacting the ADC Service Department, they must be given the correct model number and serial number for the dryers.

NOTE: Any wiring changes or conversions should be accomplished by a qualified electrical technician.
