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.
If you have questions that are not addressed in this
manual, contact Customer Support at

key to turn on the oven. The correct voltage will be
enlarged on the screen, identifying which option to
select (see Figure 3 below).
Ventilation
The TurboChef TurboChef Soˇta (model NGO)
oven has been approved by Underwriter’s
Laboratory for ventless operation (UL KNLZ list-
ing) for all food items except for foods classified as
“fatty raw proteins.” Such foods include bone-in,
skin-on chicken, raw ham¬burger meat, raw bacon,
raw sausage, steaks, etc. If cooking these types of
foods, consult local HVAC codes and authorities to
ensure compliance with ventilation requirements.
To ensure continued compliance with all health,
building, and fire codes, you are required to main-
tain clean and sanitary conditions around your
oven at all times.
NOTE: In no event shall the manufacturer assume
any liability for damages or injuries resulting from
installations which are not in compliance with the

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). The oven will not cook unless settings are present.
Note that the steps below are not always sequential. Typically, multiple items are cooked before cooling the
oven (Step 10).
