Original Instructions
Theory of Operation
Utilizing technology that combines Convection and Hot Air-Impingement along with Microwaves, the ARX-MRX
family of High Speed Combination Ovens rapidly cook food without sacrificing quality in a small footprint. The
controls allow either programmed or manual cooking to coordinate air velocity and microwave production as needed
to meet the cooking requirements of the specific product. The on-board catalytic converter allows for ventless
installation
Sequence of Operation
The oven is turned “ON” and allowed to come up to the programmed cooking temperature
With a Menu Item loaded into the oven cavity and the door closed, the operator can either select from a list of
preprogrammed menus or input manual cooking instructions
There are cooking stages that can have different levels of microwave energy and impingement air velocity.
Once initiated, the oven’s Controller will signal the Magnetron circuit to operate from 0 to 100% by modulating the
circuit on and off (or on 100%) based on the program. Simultaneously, the Controller will regulate the Convection
Blower’s speed from 0 to 100% based on the program At the end of each cooking stage, the oven can change to a
different microwave level and/or blower speed.
During these cooking stages, the oven controls the cooking temperature by energizing and de-energizing a heating
element
