INTRODUCTION
The Model C835 has two independent upper
platens. This grill provides automatic leveling
of the platens.
The grill is capable of cooking a variety of
products and features two cooking options,
AUTO and MANUAL.
AUTO Option: The grill automatically detects
the product placed on the grill plate (menu
items that are cooked using the clamshell,
only) and sets the appropriate cooking
parameters.
MANUAL Option: After the operator selects
the desired product to be cooked, the grill
automatically sets the appropriate cooking
parameters.
These grills provide all of the features of a flat
grill, as well as the advantages of two-sided
cooking.
All repairs must be performed by an
authorized Taylor service agent. The main
power supplies to the grill must be
disconnected prior to performing any repairs.
This grill is designed for indoor use only.
Note: Only instructions originating from the
factory or its authorized translation
representative(s) are considered to be the
original set of instructions.
