Grounding Instructions

This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This oven is equipped with a cord that has a grounding wire with a grounding plug, which must be plugged into an outlet that is properly installed and grounded. Consult a qualified electrician or serviceman if uncertain about the ability to follow grounding instructions or if doubt exists as to whether the appliance is properly grounded.

X DO NOT use an extension cord. If the power cord is too short, have a qualified electrician or serviceman install an outlet near the appliance.

WARNING: Improper grounding can result in risk of electric shock.

Power Cord Replacement

If the power cord is damaged, it must only be replaced by the manufacturer, its service agent, or a similarly-qualified person.

Precautions to be Observed Before and During Servicing to Avoid Possible Exposure to Excessive Microwave Energy

(a)DO NOT operate or allow the oven to be operated with the door open.

(b)Make the following safety checks on all ovens to be serviced before activating the magnetron or other

microwave source, and make repairs as necessary: (1) interlock operation, (2) proper door closing,

(3) seal and sealing surfaces (arcing, wear, and other damage), (4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.

(c)Before turning on microwave power for any service test or inspection within the microwave generating compartments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections.

(d)Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the owner.

(e)A microwave leakage check to verify compliance with the Federal Performance Standard should be performed on each oven prior to release to the owner.

Refer to pages 25-26 for leakage test procedures.

RF Interference Considerations

The i3 oven generates radio frequency signals. This device has been tested and was determined to be in compliance with applicable portions of FCC part 18 requirements and to the protection requirements of Council Directive 89/336/EEC on the approximation of the laws of the Member States relating to electromagnetic compatibility at the time of manufacture. However, some equipment with sensitivity to signals below these limits may experience interference.

If your equipment experiences interference:

aIncrease the physical separation between this oven and the sensitive equipment.

aIf the sensitive device can be grounded, do so following accepted grounding practices.

aIf battery-powered microphones are being affected, ensure that the batteries are fully charged.

aKeep sensitive equipment on separate electrical circuits if possible.

aRoute intercom wires, microphone wires, speaker cables, etc. away from the oven.

Theory of Operation

Utilizing TurboChef’s patented technology to rapidly cook food without compromising quality, the i3 oven provides superior cooking performance while requiring minimal space and energy consumption. The control system precisely coordinates independent top and bottom impinged airflow with microwave to deliver superior quality and throughput. The toplaunched microwave system allows for use of most standard metal pans, and integral catalytic converters allow for UL®-certified ventless operation (see page 4 for details and limitations).

This manual includes instructions for servicing, troubleshooting, installing, cleaning, and operating the i3 oven. If you have questions that are not addressed in this manual, contact Technical Service (800.90TURBO, [phone]) or your Authorized Distributor.

10 OVEN CONTROLS AND COOKING

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 1: Turn the Oven On

READY TO CLEAN

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.

TEMP 1: 500F

TEMP 2: 350F

Figure 8: Cook Temperature Select

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 3: Warming Up

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

WARMING UP

OVEN CC = 244F

OVEN SP = 500F

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 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.
