DAILY OPERATION
CERTAIN SURFACES ARE EXTREMELY HOT DURING
OPERATION AND CARE SHOULD BE TAKEN WHILE
USING THIS UNIT.
DO NOT LEAVE THE UNIT IN OPERATION WITHOUT
AN ATTENDANT.
DO NOT LEAVE THE UNIT AT HIGH TEMPERATURE
WHEN NOT IN USE OR DURING IDLE PERIODS.
START UP / PREHEAT
i. When the toaster has been plugged into a suitable
outlet and power supply, the power switch can be
flipped up to turn the unit on.
ii. The toaster will enter into its PREHEAT mode and
a 15-minute countdown timer will appear on the
screen. The fans and conveyors will turn on and the
radiant elements will begin to heat up.
iii. The unit will, by default, use the conveyor speed
and heater setting last used before the previous
shutdown.
MAIN MENU
i. DISPLAY—Once the toaster has been pre-heated,
menu products will appear in two lists on the display
separated into a left and right side. The left conveyor
and heaters are controlled
by the left side buttons
and the right side is
controlled by the right
side buttons.
ii.▲/▼ARROWS—The selected preset can be changed
simply by pressing the ▲ or ▼ on the corresponding
side until the desired preset is highlighted. The heat
and speed setting change will occur instantly. Actual
temperature changes in the heaters may require
several minutes to adjust to the desired level.
iii. MERGE—The “MERGE” buttons will cause the speed
and heat settings of the two conveyors to be the same
as the setting of the side that was pressed. For example,
if the left “MERGE” button is pressed, the right conveyor
will change its preset to match the left side's preset.
Selecting another preset will return the toaster to split
operation.
iv. REVERSE/MELT—The “REVERSE” button causes the
conveyor to stop and the word “MELT” to flash on the
screen. When the programmed amount of time has
elapsed, the conveyor(s) will reverse for several seconds
and then stop. The conveyor(s) will remain stopped until
the “REVERSE” button is pressed again or the preset
product is changed using the ▲or ▼buttons.
v. DARKER/LIGHTER—The “DARKER/LIGHTER” button
can be pressed once to activate a conveyor speed
adjustment mode from the main menu. After the
button is pressed, the words “DARK” and “LIGHT”
at the bottom of the display will turn bright yellow
indicating the function is active. The up and down
arrows will cause the belt to slow down or speed up
on the corresponding side allowing quick adjustments
in toasting color. Selecting “LIGHT” will increase
conveyor speed, while selecting “DARK” will decrease
conveyor speed. Adjustments made here will stay the
same until preset is changed or the unit is turned o.
SHUTDOWN
Disconnect power to the unit with the power button
at the end of each day of operation. The fans may
still continue to run until the toaster has completely
cooled. If the toaster must be moved after using,
allow the cooling fan to turn o before unplugging.

OTHER TOASTER FUNCTIONS
COOLDOWN MODE
COOLDOWN mode can be activated by holding the “DARKER/
LIGHTER” button and the both ▼buttons for a few seconds.
COOLDOWN mode takes fifteen [15] minutes to complete,
and causes the heaters to be turned o, but the conveyors,
display, and fan to continue functioning. This mode can be
used for cleaning or simply cooling o the unit.
STANDBY MODE
STANDBY mode can be activated by holding the “DARKER/
LIGHTER” button and the right ▲button for a few seconds.
STANDBY mode causes the unit to reduce the power supplied
to the heaters to 50% allowing power to be conserved during
slow periods. Toasting can still be accomplished in this mode,
but will take longer.
CLEANING
SUGGESTED CLEANING SUPPLIES
i. Kay® QSR oven cleaner (degreaser)
ii. Kay® surface sanitizer
iii. Mild dish detergent and water
iv. Clean cloth rag
v. Non-scratch scour pad
CLEANING PROCEDURE
Preventive maintenance for your toaster consists of the following recommended cleaning
procedures. To keep your toaster in its best operating condition, these steps should be
performed on a daily, or weekly, basis as required.
i. Turn toaster o (fans will continue to run approx. 10–15
minutes until cooled). You can also activate COOLDOWN
mode by pressing and holding the “DARKER/LIGHTER”
button and the left and right down buttons. This causes
the toaster to turn o the heating elements but keep
power to all other parts and the display.
ii. Immediately spray the oven cleaner onto the non-scratch
pad and scrub the conveyor chain while it is still warm
and moving. DO NOT SPRAY DIRECTLY ONTO THE
CONVEYOR BELT OR INTO THE COOKING CHAMBER.
OVERSPRAY ONTO THE HEATING ELEMENTS CAN
DAMAGE OR SHORTEN THE LIFE OF THE ELEMENTS.
iii. Wash the non-scratch pad then soak with mild dish
detergent. Ring the pad out so that it is only damp and
continue to scrub the conveyor belt while it is still moving.
iv. Rinse the non-scratch pad to remove all detergent and
then soak with clean, warm water. Ring the pad out so
that it is only damp, and continue to scrub the conveyor
belt while it is still moving.
v. Wipe the conveyor belt with a clean cloth dampened
with sanitizer solution while it is still moving. Allow
to air dry.
vi. Rinse the non-scratch pad and then soak with clean
warm water. Ring the pad out so that it is only damp,
and wipe exterior areas of the toaster.
vii. Wash with mild dish detergent, rinse, and sanitize
removable pieces, and allow to dry before sliding
the trays back into the unit.
viii. Once dry, the unit is ready for use.
DO NOT IMMERSE THE UNIT IN WATER
OR LET THE UNIT STAND IN WATER.
DO NOT USE A NON-STICK SPRAY ON THE
CONVEYOR BELT, IT WILL CAUSE A STICKY
BUILD-UP AND INCREASE STICKING.
DO NOT HOSE DOWN THE UNIT OR THE
TABLE/COUNTER IF THE UNIT IS ON THE
TABLE/COUNTER.

ADVANCED PROGRAMMING
CREATING A NEW UPDATE FILE
i. If a .csv file with the correct format for uploading new preset names and settings into the toaster
has not already been loaded onto a USB flash drive, a file with the correct format can be generated
by plugging a USB flash drive into the toaster while it is on. A flash drive formatted in FAT32
is strongly suggested.
ii. A screen will appear prompting an upload or download option for the toaster. By pressing the
left-side ▼, a csv file will be generated with the toaster’s current product settings and names
called “TOASTDN”.
iii. Remove the flash drive and insert it into a computer with Microsoft Excel or another application
capable of creating .csv files. Open the file and change the product names and settings to the
desired values. Save the file as a .csv file.

POSSIBLE WARNING SCREENS
CHECK FAN
Indicates that the unit is approaching its allowable temperature limit. This is meant
to be an early warning to allow the user to clear any blockages to the fan before the
high limit switch trips. If clearing the blockage does not eliminate the warning after
allowing a few minutes for the machine to cool, turn the unit o and contact the
factory or an authorized service agency for required maintenance.
HIGH TEMP SERVICE REQUIRED
Indicates that the high limit switch has been tripped and the unit has overheated.
First turn the unit o and allow it to cool. Check the lower cooling fan and clear the
fan guard of any debris or blockages. Turn the unit back on and ensure warning
does not appear again. If the error is still present, turn the unit o and contact the
factory or an authorized service agency for required maintenance.
HEATER XX FAULT
Indicates that a heater circuit has experienced a failure and is no longer functioning.
The screen will display which heater[s] have been detected with open circuits. XX
will display the position as a two digit abbreviation [TL for top left, TR for top right,
BL for bottom left, and BR for bottom right]. If resetting the power and allowing the
unit to cool does not eliminate the warning, turn the unit o and contact the factory
or an authorized service agency for required maintenance.
