An electrical diagram is located on the side of the control panel assembly (see drawing on page 37). Electrical diagrams can also be found in this manual beginning on page 38.

The electrical connections are made directly to the terminals of the heating-element contactor, which is located inside the control-panel compartment on the right side of the oven. A circular opening sized for a strain-relief fitting is located on the back of the oven near the right side (right as seen from the front of the oven, see illustration on page 15). Models with two stacked ovens have a separate electrical connection for each oven.

Use 167°F (75°C) wire for all supply lines.

Ovens are shipped wired for either single-phase or three-phase operation, depending on which was specified on the factory order. If necessary, an oven can be field-converted to use either single-phase or three-phase power (see page 34).

MINIMUM CLEARANCES

WARNING

There must be adequate clearance between the left side of the ovens and combustible construction.

Minimum Clearance from Minimum Clearance from

Combustible Construction Non-Combustible Construction Back 0" 0" Right Side 0" 0" Left Side 2" 0" Floor 0" 0"

Adequate clearance must be provided in the aisle to allow the doors to open sufficiently to permit the removal of the racks and for serviceability.

Although no clearance on the back due to heat is required, care must be taken to provide adequate air circulation into the rear of the compartment that contains the blower, which is on the right side of the oven.

Do not locate the oven adjacent to any high heat or grease-producing piece of equipment, such as a range top, griddle, fryer, etc., that could allow radiant heat to raise the exterior temperature of the oven above 130°F (54°C). DO NOT MOUNT ABOVE OTHER COOKING EQUIPMENT.

SPECIFICATIONS

VENTILATION

NOTICE

Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be covered by the warranty.

If a ventilation canopy is used, it is recommended that a canopy extend 6" past the appliance and that the bottom edge be located 6'6" from the floor. Filters should be installed at an angle of 45° or more from the horizontal. This position prevents dripping grease and facilitates collecting the run-off grease in a drip pan, unusually installed with a filter.

If an exhaust fan is used, it should be installed at least 2" above the flue opening at the top of the unit. A strong exhaust fan tends to create a vacuum in the room. Fresh air openings approximately equal to the fan area will relieve such a vacuum. In case of unsatisfactory performance on any appliance, check the appliance with the exhaust fan in the “OFF” position. Do this only long enough to check equipment performance. Then turn the exhaust fan back on and let it run to remove any exhaust that may have accumulated during the test.

NOTICE

ALF-SIZE ELECTRIC CONVECTION OVENS

IMMEDIATELY INSPECT FOR SHIPPING DAMAGE

All containers should be examined for damage before and during unloading. The freight carrier has assumed responsibility for its safe transit and delivery. If damaged equipment is received, either apparent or concealed, a claim must be made with the delivering carrier.

Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must then be signed by the carrier representative (Driver). If the bill is not signed, the carrier may refuse the claim. The carrier can supply the necessary forms.

A request for inspection must be made to the carrier within 15 days if there is concealed damage or loss that is not apparent until after the equipment is uncrated. The carrier should arrange an inspection. Be certain to hold all contents plus all packing material.

1. Cut banding straps and remove packing material.

2. Cut banding strap holding oven to wooden skid.

3. If you are installing 4" legs on a single-deck oven, go to Step 2a on this page. If you are installing 26" legs on a single-deck oven, go to Step 2b on the next page. If you are installing a double-deck oven, go to Step 2c on page 10

Step 2a: Installation of 4" Legs on Single-Deck Models

1. Raise oven sufficiently to allow clearance for the legs to be attached. Use of a lift truck or other mechanical lifting means is recommended. For safety, “shore up” and support the oven with an adequate blocking arrangement strong enough to support the load. (If it is absolutely necessary to rest the oven on its side, rest it on its left side or back side. Take care to protect the finish on the left side, and to prevent the weight from resting on the motor on the back.)

2. Attach each leg to a bottom corner of the oven by screwing it into the appropriate threaded hole.

3. Lower the oven gently onto a level surface. Never drop or allow the oven to fall.

4. Use a level to make sure that the oven is level. Each leg can be screwed in or out to lower or raise each corner of the oven.

OPERATING THE CONTROLS

A convection oven is a different type of oven that offers many features and advantages to the food service operation. The additional capabilities and features of the oven require some learning. However, the operation of the oven is not difficult to understand or control once you have some practice.

Each oven will have one of the four types of control panels:

• Models with Standard Controls are the most similar to a standard (non-convection) oven. Instructions for operating this type of oven begin on page 18.

• Models with Cycle/Cook and Hold Controls enable you to have the oven automatically enter a “hold mode” after a timed cooking period. Instructions for operating this type of oven begin on page 20.

• Models with Programmable Controls enable you to have the oven change temperature and other settings while cooking, then optionally enter a “hold mode.” You can record up to five “cook programs” which can then be re-used later. Instructions for operating this type of oven begin on page 23.

• Models with Rack Timer Controls provide five separate timers that independently time the cooking of food on each rack of the oven. The oven will tell you which rack will finish cooking next, and how much time remains. Instructions for operating this type of oven begin on page 26.

OPERATION

MOISTURE VENT

Each oven has a moisture vent that is opened and closed using the small knob located near the top left corner of the front panel of the oven (see illustration below). Usually the vent is kept open to allow moisture to escape. Close the vent (turn the knob clockwise) when doing fine baking.

Operation of STANDARD Models

Models with Standard Controls operate much like a standard oven: you turn the oven ON and select a cooking temperature. Two additional controls are used to control the fan (as described below).

The timer is a reminder to you of when to remove food from the oven. The timer does NOT control the

temperature of the oven.

To cook, do the following:

1. Turn the oven ON using the Power Switch at the top of the control panel.

2. Select the desired fan speed using the Fan Speed switch. The appropriate fan speed (HI or LOW) depends on the type of food being cooked.

3. Switch the Fan Mode switch to COOK. The fan will run continuously when the oven doors are closed (the fan does not cycle on and off with the burners). (If this switch is set to COOL the only difference is that the fan will continue to run when the oven doors are open.)

4. Set the cooking temperature by turning the Cook Temperature Control until the indicator mark on the knob is pointed to the desired cooking temperature. The Heat On indicator will light when the burners are on, and will remain on while the oven preheats.

5. Wait until the Heat On indicator has come on and gone out three times. At that time the oven will have reached the set cooking temperature.

6. Open the oven doors, load the product into the oven, and close the doors.

OPERATION

7. You can use the Cook Timer as a reminder of when the remove the load from the oven. If so desired, turn the Cook Timer knob until the indicator mark points to the desired cooking time (up to 55 minutes). The timer knob will rotate counterclockwise as the timer runs down, indicating how much time remains. You can turn the knob while cooking to increase or decrease the remaining time. When the timer runs out, a buzzer will sound for a short time, then turn itself off. (To immediately silence the buzzer, turn the Cook Timer knob to the OFF position.) The timer is a reminder to you; the timer does not control the

oven.

If you open the oven doors, the burners and fan will shut off until the doors are closed. However, the timer will continue running even if the doors are open.

For ovens that are equipped with an oven interior light, to turn on the light press and hold the switch located at the bottom of the control panel.

8. When the load has finished cooking, you can rapidly cool the load by opening the oven doors (which will shut off the burners) and switching the Fan Mode to COOL (which will cause the fan to run even though the doors are open). For the most rapid cooling, also switch the Fan Speed switch to HI.

9. When you are done cooking, turn the Cook Temperature control to the lowest setting (fully counterclockwise) and switch the Power Switch to OFF.

Operation of CYCLE/COOK and HOLD Models

CYCLE/COOK and HOLD models have electronic controls that enable the oven to cook food at a specified cook-temperature for a specified time period, then enter an optional Hold Mode during which the oven maintains a specified hold-temperature for an indefinite period of time.

Whenever the power switch is on, the oven will be in one of two modes. In Cook Mode, the oven maintains the specified cook temperature and the fan runs continuously, unless the Cycle option is enabled, in which case the fan cycles (on for 30 seconds, then off for 30 seconds). In Hold Mode, the oven maintains the specified hold-temperature and the fan runs only when the burners are on. (However, whenever the Fan Mode switch is in the COOL position, the fan will run continuously.)

To cook, do the following:

1. Turn the oven ON using the Power Switch at the top of the control panel. The oven will be in Cook Mode, and will begin to heat to the temperature displayed in the temperature display window.

2. Set the desired cook-temperature (from 150°F to 500°F) by pressing the up-arrow and/or down-arrow buttons to the right of the temperature display window. The temperature display will flash while the oven preheats. The Heat On indicator will light when the burners are on. To view the actual oven temperature at any time, press the up-arrow and down-arrow buttons simultaneously.

3. Switch the Fan Mode switch to the COOK position (if it is not already in that position). The fan will run when the oven doors are closed (the fan does not cycle on and off with the burners). (If this switch is set to COOL the only difference is that the fan will continue to run when the oven doors are open.)

OPERATION

4. Select whether you want the fan to cycle during cooking by pressing the Cycle button. If the Cycle indicator light is on continuously, the fan will run continuously. If instead the Cycle indicator light is flashing, the fan will cycle on for 30 seconds and then off for 30 seconds while cooking. Fan cycling is used for delicate products such as meringues and muffins which need to set, and is usually combined with the LOW fan speed (selected in the next step).

5. Select the desired fan speed by pressing the Fan Speed switch. The appropriate fan speed (HI or LOW) depends on the type of food being cooked.

6. Select the desired cooking time by pressing the up-arrow and/or down-arrow buttons to the right of the time display window. Holding down a button will speed-up the rate at which the displayed value changes. Lights under the displayed time indicate if the displayed time is in minutes-and-seconds or in hours-and-minutes. The time setting will not start counting down until you tell the oven to start cooking (in Step 9).

7. If you want the oven to enter a lower-temperature Hold Mode after a timed cook period, press and hold down the Hold button. The temperature display will now show the oven temperature (140°F to 200°F) desired during the hold mode. You can change the desired holding temperature using the up-arrow and down-arrow buttons to the right of the temperature display window (while holding down the Hold button). If you want the oven to enter Hold Mode after the cook time, be sure that the Hold Mode Indicator is lit (if it is not, press and release the Hold button so that it becomes lit). Note that when Hold Mode starts the actual oven temperature will not immediately drop to the holding temperature since it takes time for the oven interior and the load itself to cool.

CAUTION

Care should be exercised in holding products over extended periods of time or at very low holding temperatures, due to possible bacteria growth. A competent authority on food bacteria growth should be consulted if there is doubt regarding safe holding times and temperatures.

8. Wait until the oven has reached cooking temperature (when it does, the temperature display will stop flashing and the oven will “beep” once).

9. Open the oven doors and insert a load into the oven. Close the doors and press the Start/Stop button. The oven will enter Cook Mode and the time display will start to count down the remaining cook time.

If you open the oven doors, the fan and burners will temporarily shut off, and the time display will pause until the oven doors are closed again.

For ovens that are equipped with an oven interior light, to turn on the light press and hold the switch located at the bottom of the control panel.

During the cook time you can start or stop having the fan cycle on-and-off by pressing the Cycle button. If necessary, you can adjust the remaining cooking time and/or oven temperature using the

corresponding up-arrow and down-arrow buttons. You can also disable or enable Hold Mode. To cancel a timed-cook, press the Start/Stop button.

• If Hold Mode IS NOT enabled, the oven will start “beeping” and the time display will flash “:00”. Press the Start/Stop button to silence the alarm and the oven will return to Cook Mode. Promptly remove the load from the oven OR open and leave open the oven doors. If the oven doors are shut, the oven will maintain the set cook temperature even though the timer has run out. To rapidly cool down the load, open the doors, switch the Fan Mode switch to COOL, and switch the Fan Speed switch to HI.

• If Hold Mode IS enabled, the oven will beep 3 times to alert you that the cook time has completed. The time display will start counting up to indicate how long the load has been in Hold Mode (up to 99 hours). The temperature display will change to show the holding temperature (set in Step 7) and the burners will remain off while the oven gradually cools to the holding temperature. With the doors closed, the oven will maintain the set holding temperature until you press the Start/Stop button (usually after removing the load). Pressing the Start/Stop button returns the oven to Cook Mode, and the oven will then heat up to the specified cook temperature in anticipation of the next load to be cooked.

11. When you are done cooking, switch the Power Switch to OFF.
