SAFETY
THIS APPLIANCE IS FOR PROFESSIONAL USE AND SHALL BE USED ONLY BY QUALIFIED PERSONNEL.
WARNING: Accessible parts may become hot during use. Young children should be kept away. This appliance is not intended for
use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.”
CAUTION: THIS EQUIPMENT MUST ONLY BE OPERATED UNDER AN APPROVED HOOD SYSTEM IN ACCORDANCE WITH
LOCAL REGULATIONS IN FORCE.
DO NOT OPERATE THE GRILL UNLESS IT HAS BEEN COMMISSIONED (START-UP) BY A FACTORY AUTHORIZED SERVICE CENTER.
DO NOT operate the grill without reading this operation manual.
DO NOT operate the clamshell grill unless it has been properly installed and grounded.
DO NOT operate the clamshell grill unless all service and access panels are in place and fastened properly.
Means of disconnection, must be incorporated in the xed wiring in accordance with local wiring rules (such as a switch, fuse,
or circuit breaker). External equipotential bonding conductor provided on rear of appliance. Use as applicable, in accordance with
local wiring rules.
The Garland clamshell grill is a semi-automatic cooking appliance. The upper platen is lowered automatically, following the
manual, single-handed initiation of the cooking cycle, and raised automatically upon completion of the cooking cycle.
When two sided cooking, the area between the upper platen and the griddle plate should be regarded as a “danger zone”.During two sided cooking the operator must not be within this danger zone. When used as a at grill, then this area is no longer
a danger zone, the platens do not move. For whatever reason, be it cleaning, maintenance, normal operation, any exposed
person must use extreme caution if within this danger zone. Temperatures on solid cooking surfaces are intended to operate
above 120C (250F).
In two sided cooking the upper platen remains in the lowered position by nature of it’s own weight. It is not locked down. It
can be raised by lifting of the handle on the front of the platen, which pivots the platen about its rear mounting point.
The clamshell grill must only be used for single and two sided cooking of foodstus in a McDonald’s store.
WARNING: To avoid serious personal injury: DO NOT attempt to repair or replace any part of the clamshell grill unless all main
power supplies to the grill have been disconnected.
USE EXTREME CAUTION in setting up, operating and cleaning the clamshell grill to avoid coming in contact with hot grill
surfaces or hot grease. Suitable protective clothing should be worn to prevent the risk of burns.
WARNING: This appliance must not be cleaned with a water jet. DO NOT apply ice to a HOT grill surface.
NOTE: All warning labels and markings on the grill, which call attention to further dangers and necessary precautions.
HAZARD COMMUNICATION STANDARD, (HCS) - The procedures in this manual include the use of chemical products. These
chemical products will be printed in bold face, followed by the abbreviation (HCS) in the text portion of the procedure. See
the Hazard Communication Standard, (HCS) manual for the appropriate Material Safety Data Sheet(s), (MSDS).
WARNING: After turning the master power switch to the START position, the grill will go through an initialization process. If
the upper platens are in the lowered position they will return to their raised upper position.
MAINTENANCE - the platen support arms carriage block bearing bushes, the platen adjuster nuts, the platen support (shoulder)
bolt and the cam follower should be checked annually for wear. Should there be any noticeable play in the bearing bushes and
any visible wear on the platen adjuster nuts, platen support bolts or cam follower, then they must be replaced.
MAINTENANCE - the audible alarm that sounds at the end of a cook cycle is to advise the operator that the platen is about
to move. The function of this device may be tested by pushing the left hand CANCEL button. If no sound is heard, ensure that
the alarm volume is not set to low in SYSTEM SETUP. If there is still no sound then a service engineer should be called out to
rectify the fault.
SERVICE AND CLEANING - The grill may be secured in the grill bay by the installer using two anchors that lock onto the front
casters. If the grill is to be moved out of the bay for cleaning or service, remove the anchor from each caster by turning the knob
counterclockwise to loosen the retainer. When the retainer is free of the caster, lay the assembly aside on the oor.
CLEANING - NEVER clean the grill, interior or exterior, using a high-pressure sprayer, water jet, or any other liquid sprayer.
NOTE: If anchors are present, the anchor assembly remains fastened to the back wall of the grill bay. After service or clean-
ing is complete, return the grill to its position in the bay and reattach the anchors by placing the retainer on the caster post
and turning the knob clockwise to tighten. For safety reasons, the grill must be secured in the grill bay in this manner before
operation can resume.

INSTALLATION & STARTUP (continued)
Startup Procedure
This Garland 3-platen grill comes
with a factory startup at no
additional charge. A startup is
required to take place BEFORE
the unit is put into operation. It
is the end-user responsibility
to schedule the startup with
their local Factory Authorized
Service Agent, or notify Garland
Commercial Industries at 1-800446-8367 should you need
assistance scheduling.
A factory startup is a
comprehensive grill check
in which a factory certied
technician will document all
nal settings programmed in
the controller once various
other performance checks
are complete. The estimated
time to complete a startup
is approximately 2.5 – 3.5
hours. Please keep in mind
this estimated time when
scheduling the startup. After
hours or overtime is not covered
under warranty and will be
billed at a charge which is the
dierence between the Garland
Reimbursement rate and the
Factory Authorized Service
Centers overtime charges.
A factory startup is necessary
to start the warranty period.
The Authorized Service Center
is required to complete the
paperwork during the startup
process, and send it to Garland
Commercial Industries for
reimbursement. At the time
of receipt, Garland will start
the warranty period which will
conclude at the end of 2 years.
You may contact your Kitchen
Equipment Supplier or dial
1-866-735-1955 for more details
regarding an optional 3rd year
extended warranty plan.
All aspects of the Starup procedure must be documented using the Garland-issued

OPERATING PROCEDURES
General Overview:
The PRC grill control will allow for 2 functions, both
described in detail in the following sections
The “Normal Operating Mode”, also known as the Cook
Mode is the mode used during normal cooking. In the
normal operating mode, the operator can start a cook
cycle, cancel a cook cycle, view actual temperatures, scroll
to another menu item, and enter the Programming Mode.
The “Programming Mode” is the mode in which the
operator can program the controller’s various settings. To
enter the programming mode, PRESS and HOLD
There are currently 3 methods of cooking that can be
utilized with the MWE3 Garland clamshell:
Standard Cooking – This is the cook method that utilizes a
single gap setting for each menu item. The timer will count
down according to the selected menu item.
Multi Stage Cooking – This method of cooking utilizes 2
dierent gap settings during the cook cycle. The timer will
count down according to the selected menu item.
Product Recognition – The product recognition method
of cooking uses the magnetic switches mounted on the
upper platen arm assembly to determine the product
being cooked. Using the PR feature, the operator simply
selects the button on the controller. This will allow
the controller to know what product group to select
from. When a cook cycle is initiated, the platen will come
down and recognize the product being cooked. The
cook timer will count down according to the time set for
the recognized item. For more information on product
Recognition, see the next section; “Product Recognition.”
To turn the grill on:
The Main Power Switch – Controls power to the grill
and must be turned ON to start operation. The controller
displays will be active. Upon successful power up checks,
the controllers will displays “OFF”.
AM Operation – Release Material sheets MUST be ON at
this time and the grill surface should be free and clear of
carbon.
Once the PRC displays “OFF” press . The PRC will go to
PREHEAT mode and default to AM preheat temperatures.
To preheat to PM temperatures, press and hold .
Upon reaching the AM or PM set temperature (whichever
is selected), the grill will stabilize in temperature for fteen
(15) minutes. Once this time has elapsed, the grill will
autocalibrate. Upon completion of autocalibration, the
upper platens will raise to there normal position, and the
PRC will display “READY”.
To Select a Menu item:
Scroll forward through the list of available menu items by
pressing repeatedly. Scroll backward through the list of
available menu items by pressing repeatedly.
Menu Item Library
The menu item library is loaded in the computer based
upon the setting programmed in [CONFIGURE]->[GRILL

SERVICE MANUAL GARLAND CLAMSHELL GRILLS WITH PRODUCT RECOGNITION
COMMON PRODUCT RECOGNITION ISSUES
Product Recognition Errors can appear in 2 ways:
1. After initiating cook cycle, the controller displays “PRODUCT NOT RECOGNIZED - NO RECIPE FOUND”.
2. The controller displays the incorrect product for the product that was layed on the grill.
In both cases, the most common reasons for these 2 issues are as follows:
Overlapping Product
OVERLAPPING
PRODUCT
- Ensure that you do
not have any patties
overlapping when you
lay product. This will
fool the controller into
thinking that there is
much thicker product
on the grill than there
is
Wrinkled or Worn
Teon Sheet - Ensure
that the teon sheet
is installed and/or
wrapped correctly to
platen. A loose, worn,
or teon sheet with
tears and/or scratches
can eect product
recognition.
Platen makes contact
with Chicken Ring -
Always make sure that
the chicken ring is clear
of the adjacent platen
prior to initiating a
cook cycle.
Auto calibation done
with carbon build up
or product residue on
grill surface - Ensure
that the grill surface
is free of any carbon
build up. Debris on
the grill surface during
auto calbration will
cause the control to
mark the location
of the grill surface
incorrectly.
In any of the cases as outlined above or in any other event, perform an Forced Auto Calibration to reset the upper platen
distance to the grill surface. Prior to performing a Forced Auto Calibration, be sure to:
1. Make sure the upper platen is free and clear of any carbon build up or debris.
2. Ensure that the grill surface is scraped and cleaned.
3. Teon sheet should not be worn and be t to the upper platen tightly.
Perform a Forced Auto Calibration routine as indicated in section “PRODUCT RECOGNITION”, “TO PERFORM FORCED AUTO
CALIBRATION”.

REED SWITCH OPERATION (continued)
Explanation of calibration numbers, auto calibration, and other Reed Switch variables.
MAGNETSFRONT
44.1: PLATEN IN THE PARALLEL POSITION44.2: PLATEN RESTING ON GRILL PLATE
After the platen reaches the parallel position (44.1), the actuator will continue to run bringing the platen to a resting
position on the grill plate as shown (44.2).
Once the platen is resting on the grill surface, the linear
actuator will continue to run, lowering the platen arm even
more, causing the shoulder bolts to ride up into the arm.
This is the reason why the lock nuts are hollowed out
all the way through.
While the platen arm is lowering, the rear reed switch is
closed when it makes contact with the magnet mounted
on the arm. The number of counts from 0 gets stored in
the control as BACK REED CAL. (44:3).
The linear actuator will continue lower bringing the platen
arm down until the front reed switch makes contact with
the magnet. The number of counts from 0 gets stored in
the control as FRONTREED CAL. (44:4).
The timeline (44.5), shows negative actuator movement,
(platen arm downward), and the sequence in which
dierent reference points are achieved. Point 1 represents
the number of encoder counts from 0 at which the rear
reed switch closed (or made contact with the magnet). 2 is
the number of encoder counts from 0 that the front reed
switch closed (or made contact with the magnet).
IMPORTANT – The number of encoder counts between
points 1 & 2 is DELTA CAL (CAL). CAL must be below
200. The following conditions apply:
CAL < 200: OK
CAL > 200, < 300: “Check Platen Level” (Disables Auto
Mode, allows operation in Manual Mode only.)
CAL > 300: “Platen Not Level / Use Flat Cook”
(Disables all clamshell cooking.)
During auto calibration, after the front reed switch is made,
polarity and actuator direction are reversed, (44.6). The
actuator raises the platen arm, referencing point 3 when
the front reed switch reopens, as FRONT ZERO CAL. Point
4, when the rear reed switch opens, is recorded as BACK
ZERO CAL.
