GENERAL OPERATION & PROGRAMMING
Convection ovens constantly circulate air over and around the product. This strips away the thin layer of moisture
and cool air from around the product allowing heat to penetrate more quickly.
Cooking times can be shortened and cooking temperatures can be reduced.
To convert standard deck oven recipes, reduce the temperatrue 50° degrees and the time by 25%.
Make minor adjustments as necessary.
Always weigh your product. This will give you a more consistent size, color and quality.
Check the product near the end of the initial cooking.
Do not open the oven door during baking, as this will change the baking characteristics of the oven and make it
difcult to determine a nal program.
If the product is overdone on the outside and underdone on the inside, reduce the baking temperature.
If the product is pulling away from the edge of the pan, the temperature is too high or the cooking time too long.
A convection oven is a mechanical piece of equipment. The same control settings will always give the same results.
If the results vary, problems may be because of changes in the product preparation.

Cooking times can be shortened and cooking temperatures can be reduced.
To convert standard deck oven recipes, reduce the temperature 50 degrees and the time by 25%. Make

The lower the oven temperature the more even the bake.
Always weigh your product. This will give you a more consistent size, color and quality.
Check the product near the end of the initial cooking cycle by turning on the oven light and looking
through the oven door windows.
Do not open the oven doors during baking as this will change the baking characteristics of the oven and
make it difcult to determine a nal program.
If the product is overdone on the outside and underdone on the inside, reduce the baking temperature.
If the product is pulling away from the edge of the pan, the temperature is too high or the cooking time
too long.
The convection is a mechanical piece of equipment. The same control settings will always give the
same results. If the results vary, problems may be because of product preparation.
Opening the vent will to allow mositure to escape the cooking chamber during part or all of the cooking
process. This will allow a more crispy product, example: french fries, sh, crispy crusts. Close the vent
for dough products like cinnamon rolls, breads. This is something to experiment with to determine what
is best for your specic menu.
Loading
Here are some things to remember when loading your oven.
• When loading and unloading the oven, stage products and racks so the oven door is opened for the
least amount of time.
• Be sure that racks are level within the oven.
• Bent or warped pans can greatly affect the evenness of the cook or bake.
• If using baker’s parchment, be sure the parchment does not blow over the product. That will create
an uneven bake.
• Load each shelf evenly. Spaces should be maintained equally between the pan and oven walls, front
and back.
• Do not overload pan’s this will create an uneven bake.
• For best baking results, load the oven from the center out during random loading.
ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM
COMBUSTIBLE MATERIALS.
KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IF
SPILLS OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF
SLIPS OR FALLS.

Programming Step Contents:
Step 7 Select Product Icon,
Step 8 Select Product Name,
Step 9 Select Product Temperature,
Step 10 Select Tier Cook Time,
Step 11 Select Cooking Curve,
Step 12 Select Fan Speed,
Step 15 Continue To Next Tier
Cooking Curve: Cooking curve is a programmable function
that adjusts the cooking time to compensate for planned
times when the oven temperature would be lower than the
programmed temperature.
(i.e. temperature loses during loading and unloading).
Cooking Curve 40%, is the most commonly used. Cooking
Curve settings from 0% (no time adjustment) to 100% (max
time adjustment) are available. As a general rule the longer
the cooking time the lower the cooking curve, the shorter the
cooking time the higher the cooking curve.
Pulse Fan Function: A Fan Pulse Rate setting allows the fan to
be programmed to cycle on and off at regular intervals during
the period in the cooking cycle when there is no heat applied.
(The computer will not allow the fan to be OFF whenever the
heat is ON).
Tier Cooking: “Tiered” programming is the ability to change the
cooking temperature or fan function while cooking. (i.e. some
products may require high heat and the fan to be LO for the
rst half of the cooking cycle. Tier 1 would be programmed
with the Heat up and the fan LO and Tier 2 would then be
programmed with the heat lowered and the fan HI for the
remainder of the cycle.)
Multiple shelf baking function is disabled when using Tier
Baking programs.
