III. STEP-BY-STEP OPERATION

A. Startup Procedures

Daily Startup

1.Turn the BLOWER switch (Figure 3-6) to the “ON” or “I” position. This starts the main blower fan and the cooling fans. The blower circulates air through the air fingers and must stay on during the cooking or baking process.

2.Check to see if the cooling fans (see Figure 1-8) are operating when the blower switch (see Figure 3-6) is turned “ON” or “I”. The cooling fans cool the control components and blower motor. The cooling fans, located at the rear of the oven blows air into and through the cabinet. Air is exhausted through the front of the cabinet and also out the front of the oven. Refer to Daily Maintenance Section for fan intake checking procedure.

IMPORTANT NOTE

The cooling fan operates when the BLOWER switch is turned “ON” or “I”. It must operate to keep the control console below 140°F (60°C).

3.Turn the CONVEYOR switch (Figure 3-6) to the “ON” or “I” position. This starts the conveyor belt moving through the oven. Set the conveyor speed for the desired baking time. Refer to the following Procedures E, F and G.

4.Set the temperature controller to the desired baking temperature.

NOTE: For complete temperature controller operation instructions refer to Step C.

5.Turn the HEAT switch (Figure 3-6) to the “ON” or “I” position. Wait for the “Heat ON” light to turn on.

6.Oven will reach a baking temperature of 500°F (232°C) in approximately 20 minutes. Allow the oven to cycle for

30minutes after it has reached desired bake temperature. The oven is now ready for baking.

Power Failure

In case of power failure, turn off all switches and remove product. After power has been reestablished follow normal startup procedure.

B. Shutdown Procedure

1. Turn the BLOWER and HEAT switches to “OFF” or “O”.

NOTE: The blowers will remain on until the oven tempera- ture cools down to 200°F (93°C) at which time they will stop automatically.

2.Make certain that there are no products left on the conveyor inside the oven. Turn the CONVEYOR switch to “OFF” or “O”.
