OPERATION

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.

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)

e

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

Do not leave the unit in operation without an attendant.

CAUTION

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.
