DAILY 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.

CAUTION

CERTAIN SURFACES ARE EXTREMELY HOT DURING OPERATION AND CARE

SHOULD BE TAKEN WHILE USING THIS UNIT.

COOKING PROCEDURES

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 5.

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 conveyor speed control clockwise to a faster speed.

(NOTE: Some products may require adjustment of the speed control in order to

achieve the desired results.)
