The griddle and its parts are hot. Use care when operating, cleaning
or servicing the griddle.
Disconnect power supply and follow lockout / tagout procedures
before cleaning and servicing the appliance.
BEFORE FIRST USE
Remove all packaging material and protective plastic from the unit. It is recommended
that you clean your Vulcan VMCS griddle top thoroughly with a mild soap and water. Wipe
the griddle surface thoroughly with water and wipe dry with a soft clean cloth.
SEASONING THE GRIDDLE
Each time, before turning the unit on, apply high temperature cooking oil –about two
ounces per VMCS top plate. Work the oil into the whole griddle surface.

- 5-
After cleaning your griddle with chemicals, you should repeat the seasoning procedure for
proper cooking.
CONTROLS
The heavy duty electric griddle top section is independently controlled by a power switch,
thermostat and high limit cutoff switch. When the power switch (red rocker switch) is
turned ON, the left amber light will illuminate and power will be supplied to the
thermostat. The thermostat cover must be removed to access the thermostat adjustment
knob.
When the thermostat is turned ON, the amber indicator light to the right of the power
switch will illuminate to indicate that the element is on. When the griddle plate reaches
the desired temperature set point, the element will be turned off and the amber indicator
light will go off. The high limit cutoff switch is a safety feature that will cut power to the
heating element to prevent overheating. The high limit switch can be reset by depressing
the high limit reset button. At the end of each day, you must push the power switch to the
OFF position to turn off power to the griddle top section. See Fig. A.

USING THE VMCS ELECTRIC GRIDDLE TOP
To preheat, wipe the griddle top plate with cooking oil and set the thermostats for the
desired temperatures 10-12 minutes before cooking.
A uniform and systematic approach to loading the griddle will produce the most consistent
product results.

PRODUCT LOADING
The flat cooking surface units feature the Rapid Recovery™ plate which is a composite
material with a stainless steel surface. The grooved cooking surface units have plates
composed of standard, carbon steel. Both cooking surfaces can be scored or dented by
careless use of a spatula or scraper. Be careful not to dent, scratch, or gouge the plate
surface. Do not try to knock off loose food that may be on the spatula by tapping the
corner or the edge of the spatula on the griddle surface. Do not use hardened steel
spatulas. Use mild steel spatulas with rounded corners.
CARE AND CLEANING
The griddle and its parts are hot. Use care when operating, cleaning
or servicing the griddle.
Clean the electric griddle top regularly. A clean griddle always looks better, lasts longer
and performs better. To produce evenly cooked, perfectly browned griddle products keep
the griddle plate clean and free of carbonized grease. Carbonized grease on the surface
hinders the transfer of heat from the griddle surface to the food, resulting in spotty
browning and loss of cooking efficiency. Carbonized grease tends to cling to griddle
foods, giving them a highly unsatisfactory and unappetizing appearance.
To keep the griddle clean and operating at peak efficiency, follow these procedures:
AFTER EACH USE
Clean the electric griddle top with a griddle scraper during the work shift. Keep the
griddle scraper head flat to avoid scratching or gouging the plate. Use a cooking release
agent to prevent product from sticking to the griddle top cooking surface.
ONCE PER DAY
Thoroughly clean all stainless steel exterior panels and surfaces. Clean the cooking
surface with a non-metallic scouring pad (Scotch-Brite™).
Fig. H

- 9-
ONCE PER WEEK
Clean the griddle surface thoroughly. A mild detergent solution may be used on the plate
surface to help clean it, but be sure the detergent is thoroughly removed by wiping down
with clear water. After removal of detergent from the surface of the plate, the griddle
should be coated with cooking oil according to the instructions in this manual. Clean
stainless steel surfaces with a damp cloth and polish with a soft dry cloth. To remove
discoloration, use a griddle cleaner. If the griddle usage is very high, consider conducting
this weekly cleaning procedure more than once per week.
Do not use a brick or griddle stone for cleaning.
Do not use metallic scouring pads for cleaning.
Do not use a water-jet to clean the griddle.
Do not use chlorine sanitizer in contact with griddle. Contact can cause
discoloration, corrosion and permanent damage.
Do not use cleaning agents including Sodium Hydroxide, which is common in
household oven cleaners. Contact can cause discoloration, corrosion and
permanent damage.
CARE AND CLEANING OF TEFLON WRAP
1. In between cooking runs and during idle periods, the Teflon sheet should be wiped off
with water and a clean soft cloth.
2. After each day the Teflon sheet should be removed from the platen(s), disassembled
and placed in water with mild soap solution (no abrasive or harsh chemical cleaners
should be used). Gently wash both sides of the Teflon sheet and the hardware with the
soft clean cloth in the mild soap solution.
3. Using water, rinse the Teflon sheet and hardware thoroughly on both sides.
4. Dry the Teflon sheet and hardware using a clean soft cloth.
5. Before reassembling the Teflon sheet to the platen, clean the platen as described in
Care and Cleaning section.
