Switch Positions
FULL POWER- When in this position your unit is at Full Power and ready to use.
Adjust the Top and Bottom Variable Heat Controls and Conveyor
Belt Speed Control to your desired settings.
OFF-ROTARY: Two off positions are provided so that a single rotation to either
direction will result in the unit being turned OFF.
OFF-TOGGLE: The center position of the toggle switch turns the unit completely
OFF regardless of heat and speed control settings.
STANDBY- The standby position reduces the power to the unit to 1/4, and
therefore saves 75% of the energy consumption. In this position
your unit will stay warm and reduce the reheat time when switched
to Full Power to 20 to 30 seconds.

COOKING PROCEDURES
A. BREAD TOASTING
NOTE: Models TX710(H) and TX714(H) have an extended conveyor belt in
lue of a load up tray. Place (do not press) the product on the
extended conveyor belt for toasting or heating. Follow the
instructions listed below for cooking and operation procedures.
1. On models T710H, TX710(H), T714H, TX714(H) and B710H, S710(H),
S714(H) lower the front heat shield all the way down, leave just enough
clearance for bread slices to pass under the shield into the cooking
cavity (See illustration below).
ADJUSTABLE HEAT SHUTTER
2. Turn top and bottom heat controls to HI; turn conveyor speed control to
50.
3. Allow warm up time of 5 to 10 minutes.
4. Test with a slice of bread.
a. If toast is too light, turn conveyor speed control counterclockwise to a
slower speed.
b. If toast is too dark, turn conveyor speed control clockwise to a faster
speed.
B. MODELS T710(H), TX710H, T714(H), TX714H, S710(H), S714(H)-BUN TOASTING
1. Buns may be top or bottom toasted. Turn appropriate heat control to HI,
set conveyor speed control to 50.
2. On models with high (3") clearance (T710H, TX710H, T714H, TX714H, S710H,
S714H), lower the front heat shield as far as possible, leave just enough
clearance for the bun half to pass under and into the cooking cavity.
3. Test with a half of a bun.
a. If bun half is too light, turn conveyor speed control counterclockwise
to a slower speed.
b. If bun half is too dark, turn conveyor speed control clockwise to a
faster speed.

COOKING PROCEDURES CONT.
C. MODEL B710(H)
The model B710(H) has higher wattage tubes on the top than on the bottom,
therefore when placing the bun halves on the conveyor you should place
them cut side up.
D. DEEP TOASTING OR BAKING (Units with Variable Heat Controls).
Food products that require deep heating without exterior toasting may be
heated by reducing the oven temperature (lowering the top and/or bottom
heat controls) and cooking at slower speeds. Some foods may require more
top heat than bottom heat or vice versa. Every product will require some
experimentation to arrive at the correct balance of heat control and conveyor
speed settings. Each time a setting is changed allow about 5 minutes for the
unit to stabilize.
CLEANING PROCEDURES
1. Turn top and bottom heat controls to the OFF position.
2. For lightly soiled conveyor belts, turn conveyor speed control to fastest
setting (100) and wipe with a damp cloth.
3. For heavily soiled conveyors, turn conveyor speed control to fastest setting
(100) and wipe with a light abrasive pad.
4. Turn conveyor speed control off.
5. After the unit cools, remove interior crumb tray (as shown below) and clean.
Slide crumb tray back into position. DO NOT OPERATE UNIT WITHOUT
CRUMB TRAY IN PLACE AS THIS CAUSES OVERHEATING IN THE
CONTROL BOX AND MAY ACTIVATE THE HEAT LIMIT SWITCH.
6. Wipe exterior surface of unit.
LUBRICATION OF DRIVE CHAIN WITH A GRAPHITE BASED LUBRICANT IS REQUIRED AS
PERIODIC MAINTENANCE. CALL HOLMAN FACTORY SERVICE DEPARTMENT FOR
DETAILS.

TROUBLESHOOTING GUIDE
A. UNIT WILL NOT HEAT, CONVEYOR WILL NOT TURN.
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 WILL NOT HEAT, CONVEYOR TURNS PROPERLY.
1. Check to see if both top and bottom heat controls have been turned to
HI.
2. Push heat limit switch on front of control box as shown below.
If this reactivates the heater tubes, see HEAT LIMIT SWITCH in
section C.
C. HEAT LIMIT SWITCH
Your Holman 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 190F (88C). This heat limit switch
can be reset manually by pushing the red button on the front of the control
box.

TOP HEAT CONTROL
HEAT LIMIT SWITCH
THE HEAT LIMIT SWITCH IS ACTIVATED WHEN THERE IS NOT
SUFFICIENT AIR FLOW GENERATED BY THE COOLING FAN. WHEN
HEAT LIMIT SWITCH HAS BEEN ACTIVATED:
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.
