counterclockwise to get in the following positions.

FULL POWER

When in this position your equipment is at full power and ready to use.

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)
