1.HSI SYSTEM OPERATION

a.The HSI Module’s “red” indicator light will light for up to approximately five (5) seconds (self check routine).

If the HSI Module’s “red” indicator light stays on or flashes continuously, then the HSI module is wired incorrectly or has failed.

b. Start the drying cycle.
