The provided document is a device manual for the Clamshell Grill Models C832 & C834, manufactured by Taylor Company for McDonald's. This grill is designed for cooking various food items, particularly patties, and features automatic leveling platens.
Function Description:
The Clamshell Grill Models C832 and C834 are designed to cook food items using upper and lower platens. The grills automatically detect the product placed on the grill plate (menu items that are cooked using the upper platen) and set the appropriate cooking parameters. They are capable of cooking a variety of products and feature two cooking options: AUTO and MANUAL. The AUTO option automatically detects the product and sets cooking parameters, while the MANUAL option allows the operator to select the desired product and cooking parameters. The grills provide features of a flat grill as well as the advantages of two-sided cooking.
Important Technical Specifications:
The manual does not explicitly list detailed technical specifications such as power consumption, dimensions, or weight. However, it does mention that the grills are equipped with a power cord and a plug or other device to disconnect the appliance from the power source. It specifies that stationary appliances must have a multi-pole disconnection device with a contact gap of at least 3 mm installed in the external installation. Supply cords used with this unit should be oil-resistant, sheathed flexible cable, not lighter than ordinary polychloroprene or other equivalent synthetic elastomer-sheathed cord. The grill is designed to operate at a noise level not exceeding 70 dB(A) when measured at a distance of 1.0 meter from the surface of the machine and at a height of 1.6 meters from the floor.
Usage Features:
The grill features a control panel with various keys for operation, including:
- Fan Interlock Switch: Activates power to the grill and the exhaust fans.
- ON/OFF Key: Turns the controller on and off, and starts preheating mode.
- AM/PM Key: Toggles back and forth between AM and PM menu items.
- MANUAL/AUTO Key: Toggles back and forth between Manual and Auto modes.

The grill supports product selection, allowing operators to choose between AUTO and MANUAL modes. In AUTO mode, the grill automatically detects the product and sets cooking parameters. In MANUAL mode, the operator selects the desired product. Patty placement guides are provided for various patty types (regular, quarter pound, Angus, sausage, circular bacon) and quantities (1 to 8 patties), indicating the optimal placement on the grill for even cooking.
The grill also features a "Standby" mode to keep the grill idle and product not being cooked. To resume cooking, the "RAISE" button is pressed. The upper platen automatically raises when the Auto Leveling is complete.
