ii SAFETY INSTRUCTIONS

Specifications and Installation

SPECIFICATIONS AND INSTALLATION

1

Theory of Operation

The i5 rapid cook oven combines precisely­controlled impinged air and microwave energy to
create higher heat transfer rates than conventional
ovens. Top-launched microwave and impinged air
are stirred to further ensure even heat distribution,
while impinged air enters the cavity from the top
and bottom, generated by dual independently­controlled blower motors. The combination of this
technology with the size of the cook cavity allows
for higher throughput than other batch ovens.

This manual includes instructions for servicing,
troubleshooting, installing, cleaning, and operating
the i5 oven. If you have questions that are not
addressed in this manual, contact Technical Service
(800.90TURBO, [phone]) or your
Authorized Distributor.

Step 3: Warming Up

During this step, the oven warms to the selected or pre-set temperature.

Step 2: Select Cook Temperature

The oven can store either one or two cook temperatures. To select a
temperature, press the adjacent soft key.

Each temperature has 10 food groups assigned to it, and each group
consists of 10 food items (100 items per temperature). The operator will
only be able to cook items associated with the selected temperature; to
cook other items on the menu, a new temperature must be selected.

NOTE: If both temperature settings are the same, this screen will be
bypassed and access to all 200 food items will be allowed.

Step 1: Turn the Oven On

When the oven is off (Figure 7), 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.

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 smart card/USB drive (page 15) or
programmed manually (pages 19-20). The oven will not cook unless settings are present.

Note that the steps below are not always sequential. Typically, multiple items will be cooked before cooling the
oven (Step 10).

Step 6: Adjusting the Time

The Adjust Time option is turned off by default. If you want the ability
to modify the cook time before each cook cycle, this feature can be
turned on from the “Options” screen (see page 14).

1. If the “Adjust Time” screen appears, change the cook time if needed
by using the number keys.

2. Press Enter or bottom-right soft key to confirm and begin cooking.

Step 5: Ready to Cook or “Idle”

WARNING: Inside of oven and oven door are hot!

1. Place the food into the oven.

2. Select a food group by pressing its adjacent soft key, or press the Up or Down key for additional food
groups, if available.

3. Select an item to cook by pressing its adjacent soft key.

Step 4: Soaking

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.”

Step 7: 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 “Resume” is selected.
