THEORY OF OPERATION
INTRODUCTION
The ACCU-STEAMgriddle is constructed and uses technology like no other griddle
in the world. The diagram below is a cross-sectional view of the griddle. The griddle
cooking surface is the top of a chamber in which we have produced a unique
environment. Welded stainless steel reinforcement studs connect the chamber top to
the chamber bottom. The perimeter joints are all robotically welded and to produce a
vessel that is airtight, which is verified using a helium mass spectrometer. The
chamber is filled half full with distilled water. The remaining air is removed and the
chamber is welded shut. At this point, the chamber becomes a hermetically sealed
vessel, never to be opened again. The griddle steam chamber requires no water
or maintenance. A thermowell for a thermocouple to sense temperature and a
thermowell for the overtemp safety shutdown system are also welded into the griddle
steam chamber.
At temperatures below 212°F (100°C), the chamber is actually in a vacuum, similar to
that of a canning jar. At temperatures above 212°F (100°C), the chamber operates
under pressure. Located between the water and the bottom of the cooking surface is
the best heat transfer medium – steam, the most effective way to transfer heat. The
thermocouple senses the temperature of the steam and reports this data to the
thermostat, which energizes the heating elements. This system maintains the griddle
cooking surface temperatures to within ± 3°F (1.7°C) over the entire cooking surface
and provides a near instant temperature recovery, even in the same spot on the
griddle, when turning food in place.

WARNING
Only qualified service technicians/electricians should perform the
CAUTION
Temperatures on and around the griddle cooking surface could cause
installation to ensure that all electrical and safety requirements are met
and that all wiring is performed in accordance with all national, state and
local electrical codes.
LOCATION AND PLACEMENT
The AccuTemp ACCU-STEAMelectric griddle has been designed to be placed on a
commercial kitchen counter-top, an AccuTemp griddle stand or directly onto any flat,
level surface.
The operating temperature ranges from 200°- 400°F (93°- 204°C). Since these
temperatures can also be found on surfaces around the perimeter of the griddle, care
should be given not to install griddle next to or against, objects or surfaces with a low
melting or flash point.
severe burns.
LEVELING
The griddle must be installed in a level condition. An out-of-level condition may
cause damage to the griddle and damage of this type is not covered by warranty. Use a
spirit level resting on the griddle surface to ensure it is level front-to-back and left-toright.
If this is a counter-top installation, be sure to install the (4) rubber foot
tips provided with your griddle onto the four foot adjusters of each of the
griddle leg as shown. This will keep the griddle from sliding on the counter-top under
normal use. Once the rubber foot tips have been installed, adjust the four foot
adjusters up or down as needed to level the griddle.
If your griddle is attached to an AccuTemp stand with casters, ensure that the floor
surface is level and place the two locking casters to the “on” position.

product will result in death or serious injury.
ELECTRICAL SUPPLY
The ACCU-STEAMgriddle has been designed, manufactured and tested to meet or
exceed the demanding standards of safety set forth by Underwriters Laboratories, Inc.
To ensure that this high level of safety is maintained in your installation, it is important
that you read and understand the following information before attempting to plug in
your griddle.
ELECTRICAL REQUIREMENTS
Electrical requirements are listed on the data plate located on the right side of the
unit, near the front. All standard AccuTemp griddles are supplied with a 6ft (1.83m)
cord and the appropriate UL listed plug. Please note, that the plug is rated for 250VAC.
This plug is commonly used for both 208VAC and 240VAC installations. Make sure that
the voltage at your supply receptacle is within ± 10 % of the voltage listed on the
griddle data plate. Connection to any other voltage may cause damage to components
in the griddle and damage of this type is not covered under warranty.
GROUNDING INSTRUCTIONS
Grounding provides a path for electric current to reduce the risk of shock. This
product is equipped with a power cord having a grounding conductor and a grounding
plug.

The receptacle requirements vary between models. If you have purchased a
single-phase model, you will need a NEMA 6-50R receptacle. If you have
purchased a three-phase model, you will need a NEMA 15-50R receptacle.
These receptacles are configured as shown below.

Introduction
It is highly recommended that a survey of the kitchen site be conducted to
determine the requirements for the installation. Electrical supply, counter space as well
as counter arrangement are critical to the choice of Drop-In-Griddle options. The DropIn-Griddle is available in many options to accommodate size, control panel
arrangements and supply voltage. The model data label indicating the model
number, phase, voltage, current, wattage and UL information is located on
the bottom cover of the unit.

Counter designs that have an “L” arrangement such that the shortest part of the “L”
is to the left may require a “Right Hand Control Panel” option. A counter design that
has an “L” arrangement such that the shortest part of the “L” is to the right may require
a “Left Hand Control Panel” option. See Figure 1 for views of these configurations.

INSTALLATION PROCEDURE
1. Inspect the griddle packaging to ensure there are no missing components.
2. Complete the appropriate power disconnection procedures for existing
equipment or local power junction boxes.
3. Clean surfaces with grease solvents and dry off with clean rags or sponges.
4. Determine the location and orientation for the griddle and control panel modules.
Mark the centerline on the countertop for the griddle module, using a Carpenter’s
square. See Figure 2 for the countertop and control panel layouts. Continue the
centerline to the control panel module mounting surface. Accurate centerline
alignment of the countertop and control panel modules is critical to ensure the
correct alignment of the grease trough assembly to the griddle module.

5. The dimensional relationship between the griddle module mounting flange and
the control panel module is shown in Figure 3. The griddle module mounting
flange overlaps the countertop cutout by 0.50 inches on all four sides. Mark the
griddle module cutout on the countertop such that the front edge of the griddle
module is 0.73 inches – 2.63 inches from the control panel module mounting
surface, as shown in Figure 3. Mark the control panel module cutout on the
control panel module mounting surface, as shown in Figure 2.

6. Cut out the griddle and control panel module openings. Straighten out any dings
or bent edges in both cutouts to ensure adequate sealing between the new
griddle and the counter top surface and between the control panel and the front
surface of the counter.
7. Drill the mounting holes in the face of the counter using a #25 drill bit. Drill the
first set of holes and locate the remaining holes using the control panel as a
template.
8. Use a lifting device, if possible, to raise the griddle module above the counter
and position over cutout in countertop. Lower the griddle module carefully into
the cutout. Install the retainer clamps to the griddle module, using the ¼-20
nylock nuts (see drawing AT2A-3044, sheet 6).
