the food, the display switches over to the
remaining cooking time and the timer counts
down to zero. At this time, the door may be
opened to stir, turn, or season food.

sounds. The shutoff relay (RY1 and RY3) and
relay (RY2) are generalized and the power
transformer, oven lamp, etc. are turned off.

pad, the time of day will reappear on the display

Hot Air Exhaust Ventilation
Methods
1. VERTICAL VENTING
For this venting method, hot air rising from the
conventional range below is drawn in by the hood fan
motor through the grease filters at the right and left
sides of the base cover, up through the right and left
sides of the oven cavity, then discharged vertically at
rear center top of the oven, into the customer's vent
system.
2. HORIZONTAL VENTING
The air handing is the same as VERTICAL VENTING
except that the final air discharge is directed
horizontally out from the top rear of the oven into the
customer's vent system.
3. RE-CIRCULATION (INSIDE VENTING)
The air handing is the same as VERTICAL VENTING
except that the final air discharge is directed
horizontally through the upper front of the oven into
the kitchen. In this case, the accessory charcoal filter
RK-230 must be provided to filter the air before it
leaves the oven.
