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.

SECURITY COVER :

Your Holman models S710 and S714 are quipped
with a full front key locking cover (fig.1). This over fits
over the front and sides of the unit. The security
cover must be removed with a key in order to gain
access to the controls, side panels, legs and toast
chute to be removed.

To remove, unlock the cover using the key. Pull
locked side of cover out and away from the unit. The
right side will release at the same time.

TOAST CHUTE ;

To install the toast chute (fig. 2), Remove the left side
panel by removing two screws and pulling the top
part of the panel out while lifting up. Remove the
mounting rod by sliding it through chassis.

Next, place the toast chute beneath toaster as
shown. Line up the looped end of toast chute with
holes in the rear of toaster as shown. Insert mounting
rod through the holes in chassis and the toast chute
(If legs have not been installed, do so now).

Reinstall side panel and secure with screws. Toast
chute is now ready for use.

LEGS :

To secure the toaster to the counter (fig.3), Remove
both side panels by removing two screws and pulling
the top of the panel out while lifting up. Unscrew the
foot of each leg and slide counter-mounting brackets
onto the legs. Screw the foot back onto each leg and
install legs onto the toaster. Place the small cotter pin
through the holes in threaded portion of each leg.

Secure the mounting brackets to the counter with a
screw or bolt. Reinstall both side panels and secure

COOKING PROCEDURES

A. BREAD TOASTING

MODELS T710(H, TW, TX) T714(H, TW, TX) S710(H) S714(H) B710H

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.

C. MODEL B710(H)

MODELS T710(H, TW, TX) T714(H, TW, TX) S710(H) S714(H) B710H

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.

HEAT LIMIT SWITCH

TOP HEAT CONTROL

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.
