C. Start Up Procedures -- Electric Ovens

1. Turn blower switch to the"ON" position. This starts the main blower fan and cooling fan. The blower circulates

air through the air fingers and must stay on during the cooking or baking process. The cooling fan cools the electrical components and blower fan motor of the oven.

2.Check to see if the cooling fans (see Figures 1-4 and 1-6) are operating when the blower switch is turned "ON". The cooling fans cool the electrical components and burner blower motor. The cooling fan, located at the rear of the machinery cabinet blows air into and through the cabinet. Air is exhausted out the back of the oven. A cooling fan is also located in the bottom of the control box to draw air through the rear louvers and out the bottom.

Clean the cooling fan grills and louvers daily.

IMPORTANT NOTE: The cooling fan will operate when the blower switch is turned "ON". It must operate to keep the machinery cabinet below 140°F. (60° C.).

WARNING: IF FAN BLADE IS NOT ROTATING, BROKEN OR IF FAN ASSEMBLY IS MISSING FROM MAIN BLOWER MOTOR SHAFT, DO NOT OPERATE OVEN. REPLACE COOLING FAN BLADE BEFORE OPERATING OVEN. Serious damage could be done to the burner blower motor and/or the solid state electrical components if oven is operated while cooling fan is not running or vent grill is plugged.

3.Turn conveyor switch to the "ON" position. This now starts the conveyor belt moving through the oven. Set

conveyor speed digital control for desired bake time .

4. Set desired temperature on temperature

controller. Refer to previous Section B for complete temperature

controller operation instructions. See section on bake times to determine desired temperature.

5.Turn the heat switch to the "ON" position. This will complete a circuit which supplies power to the heater.

6.Close front window.

7.When oven reaches desired temperature, wait at least 30 minutes before baking.

Power Failure

In case of power failure, turn off all switches, open oven window and remove product. After power has been reestablished follow normal start-up procedure.
