Introduction
The models contained in this Operator Manual are
the C850 ,C852, C854 and C856. The Model C850
is an electric grill with one upper platen. The Model
C852 is an electric grill with two independent upper
platens. The Model C854 is an electric grill with one
upper platen and a shortened lower cooking
surface. The Model C856 is an electric grill with two
independent upper platens and two independent
shortened lower cooking plates.
These grills provide automatic leveling of the plates.
They are capable of cooking a variety of products
and feature two cooking options, AUTO and

AUTO Option: The grills automatically detect the
product placed on the grill plate (menu items that
are cooked double-sided, only) and set the
appropriate cooking parameters.
MANUAL Option: After the operator selects the
desired product to be cooked, the grills set the
appropriate cooking parameters.
These grills provide all the features of a flat grill, as
well as the advantages of two-sided cooking.

components and cause injury from hot steam.
DO NOT operate the grill unless it is
properly grounded. Failure to comply may result in
equipment damage or personal injury.
All repairs must be performed by an
authorized Taylor service technician. The main power
supplies to the grill must be disconnected prior to
performing any repairs.
These grills are 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.
This unit is provided with an equipotential
grounding lug that is to be properly attached to the rear

2
of the frame by the authorized installer. The installation
location is marked by the equipotential bonding symbol
(5021 of IEC 604171) on both the removable panel and

with a power cord and a plug or other device to
disconnect the appliance from the power
source must have an all-pole disconnecting
device with a contact gap of at least 3 mm
installed in the external installation.
SAppliances that are permanently connected to
fixed wiring and for which leakage currents
may exceed 10 mA, particularly when
disconnected or not used for long periods, or
during initial installation, shall have protective
devices such as a GFI, to protect against the
leakage of current, installed by the authorized
personnel to the local codes.

oilresistant, sheathed flexible cable not lighter
than ordinary polychloroprene or other
equivalent synthetic elastomersheathed cord
(Code designation 60245 IEC 57) installed
with the proper cord anchorage to relieve
conductors from strain, including twisting, at
the terminals and protect the insulation of the
conductors from abrasion.

replaced by an authorized Taylor service
technician in order to avoid a hazard.
Failure to follow these instructions may result in
personal injury, equipment damage, or poor grill
performance.
SThis appliance must be isolated from all
