The exclusive Fire Suppression System (F.S.S.) will extinguish fires that may start in the
drying tumbler.  A series of sensors positioned throughout the tumbler and interfaced with
the microprocessor will trigger the F.S.S. water jet(s) to quickly extinguish the flames.  The
water jet(s) remain on for 2 minutes and will automatically activate again if a fire condition
remains or reignites.  While the water jet(s) are activated, the tumbler will jog to move the
water throughout the load.  The microprocessor will display that the system was activated
and will continue to display until the dryer is attended to.

We have tried to make this manual as complete as possible and hope you will find it useful.
