GENERAL

• Your Hobart FlashBake oven is a versatile oven that employs revolutionary high-quality, high-speed cooking technology. The baking process is so fast that food retains its natural juices. Bread products brown and become crisp while vegetables retain their color and texture.
• FlashBake ovens use visible and infrared light energy to cook by radiative heat transfer. The infrared energy browns the surface of the food, while the visible light energy penetrates and heats it internally. Using the proper combination of visible and infrared light energy, the FlashBake oven provides efficient, high-speed baking and high-quality food. The HFB6 FlashBake oven may be ordered with a 6-foot (1829 mm) power cord for receptacle installation, or with a junction box for direct line connection.

INSTALLATION

Before installing, verify that the electrical service agrees with the specifications on the rating plate located on the rear of the oven. If the supply and specifications do not agree, do not proceed with the installation. Contact your dealer or your local Hobart-authorized service office immediately.

• Turn the oven on by pressing the ON/OFF button. After a few seconds, the display will settle on Recipe 1. At this point, hold down the 1 button and push the 8 button at the same time. The display at right appears:
• Press the 1 button to begin the lamp test. The door will lock and the lamps will each turn on briefly. After each of the four lamps are turned on successfully, the display will report Lamp OK. When all lamps pass, the oven will automatically return to the normal operating mode.
• If a lamp does not operate properly, the test will stop and the display will show the number of the lamp that failed. The display at right is an example:
• Press any key to continue the test. At the end of the test, the display will show “Lamp Check Finished.” If a lamp was reported as an error, retest and verify visually that the lamp did or did not light.
• If either of the two light sensors failed to operate during the test, you will see the message at right at the end of the test:
• If either a lamp or a sensor are reported as a problem, call your local Hobart-authorized service office.

Voltage Test

• After performing the lamp test, the display will return to Recipe 1. On a new oven, the display will say Empty Recipe.
• Press the green START button. The door will lock, the blower will start, and a few seconds later the cycle will end and the door will unlock. Now hold down the 1 button and push the 7 button at the same time. The display reports the system voltage.
• The voltage reported on this screen must match the nominal system voltage supplied to the oven, either 208 Volts or 240 Volts. Call your local Vulcan-authorized service office if it does not match.

OPERATION

WARNING: THE OVEN AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING, OR SERVICING THE OVEN.

PRECAUTIONS

• Never attempt to open the oven door while a cook cycle is in progress. Never attempt to operate the oven with the door open.
• Do not operate the oven without the grill, or with missing or damaged lamp shields.
• Never operate the oven without food inside.
• Before removing a pan from the oven, prepare a place to put the hot pan. Do not place the hot pan on wood, plastic, Formica, or other burnable surfaces.
• When removing pans from the oven, use a pan grabber and hot pads designed to withstand high temperatures.

UTENSILS TO USE
We recommend using FlashWare (9″ and 12″ Pyroceram), Metal, Aluminum and Silverstone pans.

COOKING HINTS
Experiment. Try various combinations of time and power levels until each of your recipes results in a perfectly cooked product. Some rules of thumb:

• Generally, try to cook as quickly as possible. Cooking for longer periods at lower intensities may reduce the quality of the food.
• Consistent preparation and storage of foods to be cooked in the oven will result in consistent cooking results. If oven settings are developed for a pizza using refrigerated and portioned ingredients, then this is how the pizza should be prepared every time or the results will vary.
• Cooking times should decrease if foods are at room temperature instead of refrigerated, foods are more dry and porous, foods are flat or thin, uniform size pieces are cooked, or black cooking pans are used.
• Cooking times should increase when foods are thick and/or dense, foods are frozen, the number of food items in a portion is increased, and foods have high moisture content.
• Keep the lamp shields and interior cavity clean. Baked-on grease and food particles will reduce the efficiency of the oven and affect the cooking process. See the CLEANING section of this manual.
• For best results when experimenting with a new product or recipe, try to start each test cook cycle from a cool oven.
