VERY IMPORTANT

PLEASE READ CAREFULLY

The QSR team is very proud to announce a new addition to our product offering. In addition to the Clam Grill manufactured exclusively for McDonald's Corp, we bring you the "Menu-Flex Oven". The "Menu-Flex Oven" is unique in many ways and you have been chosen to be one of a few to initially test it!

What's so unique about it ? Well, this is a Rapid Heat, Menu Flexible Microwave Assisted Convection Oven ! …. Yes, that's right, a Microwave Assisted Convection Oven. A Convection Oven that will be programmed to add a sudden burst of Microwave power when needed resulting in reduced cook times without jeopardizing the Food Quality, Taste and Safety.

The oven has a unique controller that will control menu items and categorize them! With the ovens’ flexible capabilities, you can program numerous menu items to satisfy your needs.

The enclosed information will serve as a guideline through its testing phase, as well as preliminary service information for the local service representative. Please read all information thoroughly and carefully. Please fill out all pertinent information as required and if there are any questions at all, feel free to call us at 1-800-446-8367, 24 hours a day, 7 days a week... Or drop us an email at clamshell@garland-group.com.

Thank you for working with the QSR team on this exciting

new project,

“The Menu-Flex Oven

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 test or inspection within the microwave generating compartments, check the magnetron , wave guide or transmission line, and cavity for proper alignment, integrity, and connection.

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.

SAFETY

Please remember that it is wiser not to attempt a service task if you are unsure of being able to complete it competently, quickly, and above all safely.

To avoid injury to you, and to protect the appliance from possible damage, please follow this Safety Code when servicing these ovens.

Before attempting to repair the oven, check it for microwave leakage.

Check that the oven is not emitting microwaves, even when supposedly not in operation.

Check that the oven is not operating continuously, whether the display indicates cooking or not.

Always discharge the HT capacitors before working on the oven using a suitably insulated 10 M ohm Resistor.

Before removing any covers from the oven, do all of the following.

•

Switch off the mains supply and remove the plug from the wall socket.

•

If the oven is hard wired, ensure that the power is turned off at the isolator switch.

Note:

The On/Off switch on the oven is not adequate protection against electric shock, as it does not isolate all of the internal wiring from the mains.

Upon completion of a service on a Mealstream oven, or before reconnecting the appliance to the electrical supply for testing, check all of the following points:

•

All internal electrical connections are correct (see wiring diagram Pages xxxxxx).

•

All wiring insulation is correct and is not touching a sharp edge.

•

All Earth connections are electrically and mechanically secure.

•

All door safety interlocks are secure and mechanically sound.

•

The door operation is smooth, and the arms run freely in the slots.

•

The door activates all three of the door interlock switches in the correct order (see pages xxxx).

•

The temperature sensor is correctly connected to the Power PCB.

•

All of the electronics are functioning correctly, and all of the touch pads are working.

•

The power output of the oven is correct.

•

Microwave emission is below permissible limit - 4 mW/cm².

•

Oven has correct 2 inch ( 50mm ) air gap all round and 2 inch ( 50mm ) above. Airflow should not be restricted.

This appliance must be connected to a grounded, metallic, permanent wiring system, or an equipment grounding conductor should be run with the circuit conductors and connected to the equipment grounding terminal or lead on the appliance.

2 inches

32 1/2 inches

In order to maintain adequate ventilation for air intake and exhaust, and to allow access for cleaning filters, you must allow a minimum of 2 inches ( 50 mm ) clearance at the sides and rear of the oven, and at least 2 inches ( 50 mm ) above (Figure 3-1).

Air intake temperature should not exceed 60°F excessive temperature will lead to reduced operating duty cycle or premature ageing of internal components. Failure to comply with these conditions will invalidate the warranty.

NEVER Install an oven above fryers, grills, griddles or any other major heat source.

ALWAYS Place containers in the cavity carefully - impact damage may chip the vitreous enamel coating on the runners and baffle plate.
