OVEN AIR JET- This push button is used to activate the Oven Air
Jet system when the machine is running in Auto Cycle with the Ovens
ON. When Oven Air Jet is actuated, the oven heaters turn off, air is blown
into the bottom oven, and the machine immediately stops the forming pro-cess. The platens retract and then the machine goes into a major fault.
The purpose of the Oven Air Jet system is to prevent fires in the oven by
turning the heaters off, blowing air into the bottom oven to keep the hot
plastic sheet off of the heaters, and to place the machine in a condition
where the wheel can be rotated to remove the sheet from the oven
