Speci cations and Installation
1.1
Theory of Operation
e TurboChef® Residential Speedcook oven
combines high-speed forced air impingement and
microwave energy to cook food up to 15 times faster
than a conventional oven. e re-circulating air
transfers heat to the food and then passes through
a catalytic converter where excess grease and odors
are removed and combusted. Simultaneously, precise
bursts of microwave energy cook the food from the
inside out. is combination of heating technologies
quickly cooks food and seals moisture to help ensure
chef-quality results in a fraction of the time.
is manual includes instructions for servicing,
troubleshooting, installing, cleaning, and operating
the TurboChef Residential double and single wall
ovens. If you have questions not addressed in this
manual, contact Technical Service (866.447.3783,
+1 214-379-6000) or your Authorized Distributor.
Catalytic Converter
e catalytic converter removes odors and grease
from the air inside the cook cavity. It is also
responsible for limiting and removing any smoke
from the cavity in case of a spill. Do not use oven
cleaner when cleaning the Speedcook oven, as the
catalyst can become damaged by the use of caustic
cleaners, resulting in a non-warranty service call.
See pages 2.10, and 3.4 for approved self-cleaning
instructions.

Installation
Cabinets should be cut according to dimensions on
pages 1.4 and 1.5. Failure to adhere to the Rough
Wall Opening specifi cations may cause corners of
the cabinet opening to be exposed. If the oven is
being installed near a wall or door, there should be at
least .25 in (6.35 mm) space between the wall/door
and the sides of the oven trim.
TurboChef recommends using standard 2x4 wood
support posts with a minimum of .5 in (12.7 mm)
solid base to support the oven. Support posts should
be level with the fl oor line and well secured to the
base of the cabinet. Base cabinet support must be
able to support the oven’s weight – 410 lbs (186
kg) DWO and 230 lbs (105 kg) SWO. TurboChef
strongly recommends a solid base as shown in the
illustrations on the following page.
Due to the oven frame’s overall depth, adhere to the
power supply line location shown in Figures 1.2 and
1.3 on page 1.4 to obtain a proper fi t in the cabinet.
If necessary due to a low or high conduit box, a 2”
diameter hole should be drilled where indicated to
allow the power cord to reach the power source.
NOTE: DO NOT shorten conduit. Correct conduit
before installing oven into cabinet.
e oven utilizes ambient air from the kitchen to
assist in keeping the operational components cool.
is air is drawn in through the top control panel
area through openings in the top access panel and
exhausted through an opening at the base of the
oven. Please allow a 1-inch minimum clearance
above and below these areas.
Should you have any questions or concerns about
how the cabinets are built, please contact TurboChef
Customer Service 866.447.3783 before installing the
oven.
Installation Safety Instructions
Read all installation instructions thoroughly before
installing.
CAUTION: DO NOT lift the oven by the
door handle(s). Doing so will require a door-leakage
test to be performed (see page 5.4), and could cause
the door(s) to come off or misalign, requiring repair
and/or replacement.
CAUTION: e Double Wall Oven weighs 410
lbs (186 kg), and the Single Wall Oven weighs 230
lbs (105 kg). Two or more individuals are required to
lift either oven.
CAUTION: DO NOT remove bottom wood
support rails until the oven is lifted into the cabinet.
Due to the oven’s weight, it is sometimes
necessary for installers to utilize special handling
equipment, such as hand trucks, dollies, etc. Use
of such equipment can damage the kitchen fl oor
surfaces. TurboChef recommends that all exposed
fl oor surfaces be protected by applying laminate
or plywood sheets, along with protective moving
blankets before using such equipment. Failure to
do so may result in scarring and damaging the
homeowner’s fl oors.
Installation, electrical connections, circuit
breakers, and grounding must comply with local
codes.
Ensure power is disconnected at the breaker
throughout the installation process.
is oven contains breakable components – use
extreme caution when lifting and placing it.
A minimum 1-inch clearance, to allow for proper
airfl ow, is required above the top control panel
area and below the base. Failure to maintain this
clearance may cause the oven to function
improperly.
DO NOT push on the outer frame. Doing so
could cause the door(s) to misalign, requiring
repair and/or replacement.
During installation, TurboChef recommends
removing the lower door prior to lifting the oven
from the front (Double Wall Model only.) DO
NOT remove the top door of the oven during
installation or at any other time. is door should
only be removed by an authorized service agent.

OVEN CONTROLS AND COOKING THE SPEEDCOOK OVEN
2.2 OVEN CONTROLS AND COOKING THE SPEEDCOOK OVEN
Cook Modes
e Speedcook oven features seven modes that
enable the user to cook a wide variety of foods.
- Air-Crisp
- Bake
- Broil
- Dehydrate
- Favorites
- Roast
- Toast
To access Air-Crisp, Bake, Broil, Dehydrate,
Favorites, Roast, or Toast cook modes, turn the
CookWheel to the desired cook mode.
NOTE: Unlike traditional ovens or the lower double
wall oven, Speedcook oven cooking parameters will
vary signifi cantly on a cook-by-cook basis. For
troubleshooting cooking problems, see section 6 in
this manual. For information on component
measurements and testing, see section 5.

In the TurboChef® Speedcook Oven, the traditional
explanation of baking remains the same. However,
the hot air is moved through the cook cavity at
higher speeds than in a traditional oven. is rapid
movement of air decreases cook times while ensuring
foods bake evenly and retain more moisture.
When in the Bake mode, keep in mind that metal
cookware will provide more bottom browning while
items in glass cookware will cook a little faster. Bake
pizzas on a pizza pan or place them directly on the
oven rack. Some casseroles may need to be covered
with parchment paper to prevent over-browning.
Broil
Broiling directly exposes food to radiant heat (as
over a fi re or on top of a grill). e heat is direct and
intense, and it diff ers from baking or roasting in
that only one side of the food is exposed to the heat
source. Generally, broiled foods are quick cooking,
inherently tender, relatively lean, and not too thick.
e Broil mode on the TurboChef Speedcook Oven
will yield the same or superior results as broiling in
any traditional oven. e only real diff erence is that
your food cooks faster due to the hot air moving
through the cook cavity at increased speeds.
Cast iron grill pans, metal sheet pans, and metal
broiling pans all work well in this mode.
Air-Crisp
ink of Air-Crisp as air-frying. is mode is great
for foods that traditionally taste best when fried –
like french fries – as well as items containing any sort
of breading or stuffi ng that should toast and brown
in the cooking process – like stuff ed mushrooms.
In this mode, high temperature air moves through
the cook cavity at varying speeds to brown and crisp
the food product. Food comes out with a nice
caramelization and is lower in fat content than if it
had been deep fried. Metal sheet pans work well in
this mode.
Bake
Traditionally, baking is cooking with dry heat. Hot
air from the top and bottom of the oven envelopes
the food in a radiant dry heat, perhaps with a little
moisture from the food, which circulates as a vapor
in the oven.
Dehydrate
Considered the original form of preservation, dehydrating food removes the product’s natural moisture
by slowly drying it with a low heat. Manually, food
can be dehydrated by placing thin slices on racks
and allowing them to dry assisted only by sun or air.
To shorten the dehydrating process, the TurboChef
oven utilizes low temperature air moving at higher
speeds.
is mode is ideal for products like banana chips
and other dried fruits, as well as dried meats, like
beef jerky. Sheet pans, TurboChef tefl on screens, and
pizza pans (with or without holes) are all recommended for use with this mode.
Favorites
e Favorites mode is a tool that allows the user to
store and easily recall up to 9,999 cook settings for
the user’s favorite recipes. is mode truly allows you
2.3
to cook any recipe quickly and easily – regardless of
whether it is a perfect match to one of the preprogrammed settings or not. In addition to any settings that the user saves, the settings for the last ten
cooks are always saved in this mode. e Favorites
mode gives the user access to Convection Bake, Defrost, and Microwave functions. To learn more about
the Favorites mode, see below.
Roast
Traditionally, roasting implies cooking food with an
open fl ame, as on a spit in front of a fi re.
Roasting and baking in an oven are essentially the
same thing, but roasting is mostly used for meats
and vegetables. In the top oven, a combination of
low and high speed air is used to brown the outside
of food while retaining moisture inside.
Roasting pans (without lids), glass casserole dishes
(with or without lids), and sheet pans all work well
with this mode. Shallow pans will allow food to
brown more. An uncovered pan without liquids will
help keep the heat dry and allow foods to brown and
crisp. Setting meats and poultry directly on a rack in
a pan keeps them from steaming in their own juices.
Toast
Toasting browns and crisps foods like bread, bagels,
and tortillas. Using high heat and high speed air, the
Toast Mode can enhance fl avor and melt cheese.
For best results, place food directly on the oven rack.
For products that may run over, like fi lled pastries,
use a metal sheet pan.
NOTE: Convection bake, defrost, and microwave
cook cycles cannot be saved to Favorites and will not
appear in “View Last Cooked (10).”
is section contains information about the
following:
- Cooking a Recently Prepared Dish
- Cooking a “Favorite” Dish
