POWER SAVER SWITCH

Your Holman toaster is equipped with 2 rotary power saver switches.
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.

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. MUFFIN/BAGLE TOASTING

1. Turn the Power Saver Switch for the appropriate toaster chamber to FULL POWER.
