Theory of Operation
The TurboChef Encore/Encore 2 oven uses radiant
heat in combination with high-speed air impingement and side-launched microwave to cook food
rapidly without compromising quality. Performance
and menu versatility are maximized due to flexible
top and bottom temperature settings and the ability
to set the amount of microwave and air in different
phases of each recipe.
This manual includes instructions for installing,
cleaning, and operating the oven. If you have
questions that are not addressed in this
manual, contact Customer Support at

10 OVEN CONTROLS AND COOKING
Cooking
The oven is preprogrammed with recipe settings at the time of manufacture and is ready to operate out of
the box. New menu settings can be loaded via USB or smart card (page 15) or programmed manually
(page 17). The oven will not cook unless settings are present.
This oven uses impingement and microwave to cook food faster than traditional cooking methods. Air enters
the cavity from the top and bottom using a single fan. Because of this design and to ensure uniformity of
cooking, the oven must be operated only while the bottom jetplate is in place. While the bottom jetplate is
removable for cleaning, it is not removable for cooking. Without the bottom jetplate in place, the oven will
not deliver the proper cooking performance to either the top or bottom of the food item. Additionally, oven
damage may result.
The sequence of the steps below may vary, and some may not apply.
Step 1: Turn the Oven On
Step 2: Select Cook Temperature
NOTE: The top temperature will allow you to cook
items found in groups 1-8. The bottom temperature
will allow you to cook items found in groups 9-16. If the
temperatures are the same, this screen will be bypassed
and access to all food items will be allowed.
Step 3: Warming Up
NOTE: When the oven is done warming up, it will
“soak” for an additional eight minutes. “Soaking” ensures
the cavity surfaces absorb enough heat so that cooking
will not be affected. While the oven is soaking, the menu
can be seen, but cooking will not be allowed until the
timer reaches 0:00.
Step 4: Place Food in the Oven
WARNING: Inside of oven and oven door are hot!
Step 5: Cook the Item
NOTE: Press Up or Down to view more groups (only available if all items have the same set temperature) or food items.
Step 6: Cooking
NOTE: To immediately terminate a cook cycle, press
the Back/Stop key.
NOTE: If the oven door is opened during a cook cycle,
the cycle will pause until the door is closed and ENTER
is pressed to resume.
Step 7: Check/Remove Food from Oven

WARNING: Dish/inside of oven and door are hot!
Step 8: Brown More / Cook More / Cook & Brown
To cook an item longer than its original cook time, use one of the three keys on the left side of the keypad:
- Press “Brown More” if the outside of the food item requires browning or crisping.
- Press “Cook More” if the inside of the food item requires cooking.
- Press “Cook & Brown” if both the inside and outside of the food item require cooking.
Pressing one of these keys will cook the item for 20% of the last cook time selected. The minimum cook
time is the less of 15 seconds or the entire original cook cyle. The maximum is one minute. The oven will
cook at the settings listed below:
- Brown More: 100% air, 0% microwave
- Cook More: 10% air, 100% microwave
- Cook & Brown: 100% air, 100% microwave
Each additional key press while the oven is cooking adds 15 seconds of cook time to the “brown more,”
“cook more,” or “cook & brown more” cycle, up to a maximum of five minutes.
NOTE: If a cook more option is selected, the oven will beep when the timer reaches zero, but no message
will be displayed.
