Theory of Operation
Utilizing TurboChef’s patented technology to
rapidly cook food without compromising quality,
the NGO oven provides superior cooking
performance while requiring minimal space and
energy consumption. The control system precisely
coordinates independent top and bottom impinged
airflow with top-launched microwave to deliver
product-specific results, and integral catalytic
converters allow for UL®-certified ventless
operation (see page 4 for details).
This manual includes instructions for installing,
cleaning, operating, and servicing the NGO oven.

Cooking
The oven is preprogrammed with recipe settings at the time of manufacture and is ready to operate out of the
box. If these settings are erased, new menu settings must be either loaded via Oven Connect (page 4), smart
card (page 16), or programmed manually (pages 17-18).
Note that the steps below are not always sequential. Typically, multiple items are cooked before cooling the
oven (Step 10).
Step 1: Turn the Oven On
When the oven is off (Figure 5), the oven temperature has
receded below 150°F (66°C), but the display and keypad
remain on.
Press the On/Off key to turn the oven on.
The oven will not cook unless settings are present.
Figure 5: Oven Off
Step 2: Select Cook Temperature
The oven stores two different cook temperature settings (see
page 17 for more information). Only items associated with
the selected temperature setting can be cooked without
re-specifying the temperature setting.
To select a temperature, press the adjacent soft key.

NOTE: If both temperature settings are the same, this screen will be bypassed and access to all food items will
be allowed.
Step 3: Warming Up
During this step, the oven warms to the selected or pre-set
temperature.

Once the oven temperature reaches the set point, the oven will continue to warm for eight minutes to ensure
the cook cavity surfaces absorb enough heat so as to not affect cooking results. This process is called “soaking.”
NOTE: While the oven is soaking, the operator will be able to navigate through the menu, but will not be
allowed to cook until the timer reaches 0:00.
Step 5: Ready to Cook

If the Additional Cooking Options screen appears and the food product requires more cooking:
- Select “cook more” if the inside of the food item is undercooked
- Select “brown more” if the outside of the food item requires more browning or crisping.
- Select “cook and brown more” if both the inside and outside of the food item are not done.
- Select “save adjusted time” to save any change to the cook time made during Step . Note that this option
is not available if “Adjust Time” is disabled (page 12).
- Select “exit” to return to the food group selection screen.
Step 10: Cooling Down
When finished cooking for the day, press the On/Off key to turn the oven off and begin cooling down.
During this step, the oven blows cool air into the cook cavity to return it to approximately 150°F (66°C), at
which point the oven is safe to clean.
