DAILY OPERATION PROCEDURES
ROTARY POWER SAVER SWITCH
For toasters equipped with a Rotary Power Saver Switch, turn clockwise or
counterclockwise to get in the following positions.
FULL POWER
When in this position your equipment is at full power and ready to use.
OFF ROTARY
Two off positions are provided, a single rotation to either direction will shut the unit off.
STANDBY
The standby position reduces the power consumption by 75%. Using this position during the
quiet times will save electricity, and keep the toaster warm. When needed, turn the switch
to FULL POWER. Recovery time is about 30 seconds.
CAUTION
CERTAIN SURFACES ARE EXTREMELY HOT DURING OPERATION AND CARE
SHOULD BE TAKEN WHILE USING THIS UNIT.

COOKING PROCEDURES
BREAD TOASTING
Some toasters are equipped with a swinging heat shutter at the toaster entrance. This
shutter will move out of the way as the product passes under it.
1) Turn the power saver to FULL POWER.
2) Set the conveyor speed to HIGH.
3) If your toaster is equipped with separate top and bottom heat controls set them both
at HIGH.
4) Allow warm up time of 5 to 10 minutes.
5) Place a sample product on the conveyor belt to test the settings.
•If toasting is too light, turn conveyor speed control counterclockwise to a slower speed.
•If toasting is too dark, turn heat control to a lower heat.
(NOTE: Some products may require adjustment of the top and bottom heat controls
in order to achieve the desired results)

DAILY OPERATION
Check the power cord to insure that it is plugged into a proper outlet.
Set the heat control knobs to desired temperature.
Always allow 10 minutes of preheat time before loading the unit with product. Failure to allow
sufcient preheat time will result in unsatisfactory cooking until the unit reaches operating
temperature.
OPERATING HINTS AND SAFETY
Disconnect power to the unit with the switch at the end of each day of operation.
Do not leave the unit in operation without an attendant.
Turn Power Saver Switch to Standby during idle periods. It will take only a few minutes to
regain operating temperature.
Do not leave the unit at high temperature when not in use or during idle periods. This will
cause food particles and grease lm to carbonize.

Preventive maintenance for your Dualit toaster consists of the following recommended
cleaning procedures. To keep your toaster in its top operating condition, these steps should be
performed on a daily or weekly as indicated.
A. Clean air intake on bottom of unit.
B. For lightly soiled conveyor belts, turn conveyor speed control to fastest setting (100) and
wipe with a damp cloth (daily) For heavily soiled conveyors, turn conveyor speed control to
fastest setting and wipe with a light abrasive pad (as needed).
C. Turn main power saver switch to the OFF position. Disconnect unit from power source.

TROUBLESHOOTING GUIDE
A. UNIT WILL NOT HEAT, CONVEYOR BELT WILL NOT MOVE.
1) Be sure the main circuit breaker is switched to the ON position.
2) Check to see if the toaster is plugged in and all controls are turned to the ON position.
B. UNIT HAS HEAT ONLY ON ONE SIDE, CONVEYOR BELT TURNS FREELY.
1) Call the Dualit Help Desk at [phone], as heating element may need replacing.
C. CONVEYOR WILL NOT TURN, UNIT HEATS PROPERLY.
To check for mechanical binding:
1) DISCONNECT UNIT FROM POWER SOURCE.
2) Remove 2 screws holding enclosure to the bottom of the unit.
3) Set unit on the legs and remove 4 screws on the back of the toaster.
4) Slide the enclosure off the unit and remove the back panel.
5) Loosen the four screws that hold the drive motor in place.
6) Slide the motor up allowing the drive chain to be removed from the sprockets.
7) Move the conveyor belt by hand to check for mechanical binding. If conveyor moves freely,
call the Dualit Help Desk at [phone], as the drive
motor and/or speed control may need replacing.
8) Replace the enclosure by sliding it forward towards the front of the unit.
The front edge of the enclosure will slide beneath the toaster front.
D. HEAT LIMIT SWITCH (RESET)
Your Dualit conveyor toaster is equipped with an automatically activated heat limit switch that
interrupts the heater tube connections if the ambient temperature in the control box exceeds
88°C. This switch can be reset manually by pushing the red button under the toaster as
shown in the Toaster Components Illustration on Page 5.
1) DISCONNECT UNIT FROM POWER SOURCE.
2) Check to see if air intake area in the bottom center of the control box cover is free of dust,
grease or other obstructions.
3) Check if crumb tray is in place. NEVER OPERATE UNIT WITHOUT CRUMB TRAY IN PLACE
AS THIS CAUSES OVERHEATING IN THE CONTROL BOX.
4) If no obstructions to the airow can be found and if the crumb tray is in place,
call the Dualit Help Desk at [phone] for assistance.
E. CONVEYOR TURNS AT ONE SPEED REGARDLESS OF SPEED
CONTROL SETTING.
1) Call the Dualit Help Desk at [phone], as speed control should be replaced.
