COOK TIM ES AND TEMPERATURES
Preheating the oven
Always preheat the oven before baking or roasting.
We recommend preheating 50_F(10_C) above the
cook temperature to offset the drop in temperature
when the doors are opened and cold product is
lo aded into the oven. Set the thermostat to the coo k
temperature a fter the pro duct is l o aded.
NOTE: For frozen product, preheat the oven
100_F(38_C) above the cook tempera-
ture.
Cook Temperatures
Generally, cook temperatures should be 50_F
(10_C)lowerthandeckorrangeovenrecipes.If
the edges of the product are done but the center
is raw, or if there is color variation, reduce the ther-
mostat setting another15---25_F (10---15_C). Con-
tinue to reduce the cook temperature on succes-
sive loads until the desired results are achieved.
NOTE: Cooking at excessive temperatures will
not reduce cook time, it will produce un-
satisfactory baking and roasting results.
Cook Time
Check the product in about half the time recom-
mended for deck or range oven recipes. Record
times and temperatures which provide best re-
sults for future reference.
NOTE: Cook time will vary with the amount of
product loaded, the type of pan and the
temperature.
OPERATING TIPS
Pans and Racks
Product or pan height determines how many
racks are used. The oven holds up to ten 18” x 26”
(45.7 x 66.0 cm) bun pans .
Load theoven from the bottom,centering the pans
on the rack. Never place a pan or aluminum foil on
the bottom of the oven. This obstructs the flow of
air and results in uneven baking and roasting.
Roasting
To reduce shrinkage when roasting, place meat
directly on the racks. Place a sheet pan one-half
full of water in the bottom rack position. The w ater
evaporates, increasing humidity in the oven
chamber. The pan catches grease from the meat,
making oven cleaning easier.
Baking
Weigh the product to ensure equal distribution in
each pan. Varying amounts of product will cause
uneven baking results.
Fans
The fan must be operating for the oven to heat.
Use the Pulse Plus feature to allow light or liquid
product to set in the p an and to avoid rippling to-
wards the fan. If your oven is not equipped with
this feature use the following procedure.
1. Preheat the oven 25_F(15_C) above the bak-
ing temperature.
2. Loadtheovenwithproduct.Closethedoors.
3. Set the thermostat to the baking temperature.
4. Turn the oven off.
5. Allow the product to s et for 5---7 minutes with
the fan off. The residual heat in the oven sets
the product.
6. Turnthe oven on for the remainder of thebake.
Lights
Turn the oven lights off when not view ing the prod-
uct. Leaving the lights on for extended periods of
time shortens the bulb life considerably.
