A wiring diagram is included herewith. Disconnect the unit from the power source before installing or removing any parts. Be absolutely sure that the ground connection for the receptacle is properly wired. Do not connect equipment to power without proper ground connections. Improper grounding may result in personal injury or fatality.

WARNING
DO NOT CUT OR REMOVE THE SUPPLIED PLUG OR GROUNDING PRONG FROM THE PLUG.

WARNING
CONNECT/PLUG UNIT INTO DEDICATED A.C. LINE ONLY SPECIFIED ON THE DATA PLATE OF THE UNIT.

WARNING
MAKE SURE ALL INPUT IS OFF OR THAT THE UNIT IS DISCONNECTED FROM THE POWER SUPPLY BEFORE INSTALLING OR REMOVING ANY PART.

WARNING
BEFORE INSTALLING UNIT (S), CHECK WITH LOCAL POWER COMPANY TO DETERMINE ACTUAL VOLTAGE AT THE JOB SITE. NEVER PLUG A 208-VOLT UNIT INTO 240-VOLTS OR A 240-VOLT UNIT INTO A 208-VOLT.

WARNING
BE SURE THE GROUND CONNECTION FOR THE RECEPTACLE IS PROPERLY WIRED. NEVER CONNECT UNIT TO POWER WITHOUT PROPER GROUND CONNECTIONS. IMPROPER GROUND MAY RESULT IN SEVERE INJURY OR FATALITY.

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 a minimum 10 minutes of preheat time before loading the unit with product. Failure to allow sufficient preheat time will result in unsatisfactory cooking until the unit reaches operating temperature.

TOASTER COMPONENTS
The DT14 is equipped with controls on both the left and right side of the unit. The Left side, that controls the top conveyor, has one controller for the conveyor speed, and two knobs that allows you to control the top and bottom elements separately. The right side is exactly the same, but for the lower conveyor.

HIGH LIMIT RESET
Your Holman Conveyor Toaster is equipped with a temperature activated heat limit switch that will interrupt the power to the heater tubes if the temperature inside the control box exceeds 190° F (88°C). The HIGH LIMIT/RESET can be manually reset by pushing the button located at the rear of the control box as shown below.

CAUTION : CERTAIN SURFACES ARE EXTREMELY HOT DURING OPERATION AND CARE SHOULD BE TAKEN WHILE USING THIS UNIT.

COOKING PROCEDURES

A. BREAD TOASTING

1. Turn the top and bottom heat controls 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. This will toast both sides of the bread, for one sided toasting, turn off one of the heat controls.
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 controls to a lower heat.
     ( NOTE : Some products may require adjustment of the top and bottom heat controls in order to achieve the desired results)

B. BUN TOASTING (one sided toasting)

1. Depending on the size, buns may be toasted on either the upper or lower conveyor unit. Turn the appropriate heat control(s) of the desired toasting chamber to HI and set the conveyor speed control to 50.
2. For top conveyor only, lower the front heat shutter as far as possible leaving just enough room for the product to pass into the toasting chamber without being obstructed.
3. Test with a bun half
4. If bun half is too light, turn conveyor speed control counterclockwise to a slower speed.
5. if bun half is too dark, turn speed control clockwise to a faster speed.

C. DEEP TOASTING (units with variable heat controls)

1. Food products that require deep heating without exterior toasting may be heated by reducing the toaster temperature (lowering the top and/or bottom heat controls) while cooking at slower speeds. Some foods require more top heat than bottom heat or visa versa. Every product will require some experimentation to arrive at the proper heat and conveyor speed setting. Each time a setting is changed, allow approximately 5 minutes for the unit to stabilize.

OPERATING HINTS & 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 Heat Controls down 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 particle and grease film to carbonize. Product (bread) with excessive moisture or frozen will toast differently than day old bread which has less moisture. Never operate the unit without crumb trays in place at this causes overheating in the control box.

CLEANING
Preventive maintenance for your Holman 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 the front of the unit using a damp cloth. (Daily)
B. Conveyor Belt “Turn the heat controls to the OFF position”

• Using a nut driver, remove the two acorn nuts and washers from each side of the load up trays. Clean trays using mild detergent.
• For units with power saver switch only, turn the unit on and advance the conveyor belt to the next section and wipe the belt. Repeat until the entire belt has been cleaned.
• For units with individual heat controls, turn the unit to FULL POWER and turn the heat controls to the OFF position. Set the conveyor belt speed to the maximum speed and wipe the conveyor belt with a damp cloth as it turns.
• 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.
D. After the unit cools, remove interior crumb tray (as shown on page 5) and clean. Slide crumb tray back into position.
