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 HEAT/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/CONVEYOR 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 about 10 minutes. Allow the oven to cycle for 20 minutes after it has reached desired bake temperature. The oven is now ready for baking.

7.Oven will continue to run at a reduced blower speed in order to save energy, but will automatically change to the higher, baking blower speed when product is placed on the belt. The “energy eye” (photo eye) and an internal timer control these changes. The changes in blower speed are noticable and normal as the oven changes from baking to energy saving mode.

NOTE: The time setting for the baking mode should be set at installation, based upon the longest baked product time. If the blowers return to the lower, energy saving speed before the product fully exits the oven, contact your local Middleby Marshall Service Agent for timing adjust- ment.

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/CONVEYOR switches to “OFF” or “O”.

NOTE: The blowers will remain on until the oven temperature 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 HEAT/CONVEYOR switch to “OFF” or “O”.
