Theory of Operation
U
tilizing
TurboChef ’s patented technology to
rapidly cook food without compromising quality,
the NGO oven provides superior cooking
per
formance 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
conv
erters allow for UL®-certified ventless
operation (see page 4 for details).
This manual includes instructions for installing,
cleaning, operating, and servicing the NGO oven.

Installation Near Open Heat Source
When placing a TurboChef oven near an open heat
sour
ce (Figure 2), strictly adhere to the following:
- If the oven is being placed near a grill or stove,
a divider must exist betw
een the o
ven and the
open heat source, with a minimum of 6” (152
mm) betw
een the oven and the divider.
-
If the oven is being placed near a fryer, a
divider must exist between the oven and fryer,
with a minimum of 12” (305 mm) between
the oven and the divider.
-
The height of the divider must be gr
eater than
or equal to the height of the o
ven (25.0” or

For North America oven models, the oven will
detect 208 or 240 incoming voltage.
The initial voltage selection is typically completed
before the oven is used by the customer. However,
if incoming voltage for the store is different than
the preset voltage, the operator will be required to
select either 208 or 240 after pr
essing the O
n/Off
key to turn on the oven. The correct voltage will be
enlarged on the screen, identifying which option to
select (see Figure 3 below).

ep 1: Prepare the Oven
WARNING: The oven operates at approximately 525°F (274°C) and may
cause injury if not allowed to cool properly.
• Turn off the oven by pressing the On/Off key.
• S
lightly open the o
ven door.
• Cooling takes appr
oximately 30 minutes. DO NOT clean the oven until the

en displays OVEN OFF: READY TO CLEAN.
S
t
ep 2: Remove the Wire Rack and Lower Jetplate
WARNING: Be sure the oven interior is cool before removing these items.
CAUTION: Do not force the rack out by pulling upward. Forcefully
dislodging the rack could cause the top ceramic jetplate to br
eak.
• The wire rack and lower jetplate are connected and can be removed together.
• Push the wire rack towards the rear cavity wall (Fig A) and then lift up (Fig B).
• M
aneuver the bottom jetplate out from under the tabs on the rear cavity wall.
CA
UTION: DO NOT remove the top ceramic jetplate; breakage will result in
a non-warranty service call.
S
tep 3: Clean the Wire Rack and Lower Jetplate
• Detach the wire rack from the jetplate and wash, rinse, sanitize, and dry each part.
Step 4: Clean the Air Filter
CAUTION: TurboChef does not recognize blocked air vents as a warrantable
claim.
The filter must be cleaned regularly or replaced if damaged. During oven
operation, the filter must r
emain in place at all times.
• Remove the air filter from the back of the oven.
• Rinse the air filter with hot water
.
• Allow the air filter to dry completely.
CAUTION: DO NOT operate the oven without the air filter in place.
Step 5: Wipe the Oven Interior
• Use a food vacuum or damp towel to remove large particles from the oven cavity.
