COMPANY TO DETERMINE ACTUAL VOLTAGE AT JOB SITE.
NEVER PLUG A 208 VOLT UNIT INTO 240 VOLTS OR A 240
VOLT UNIT INTO 208 VOLTS.

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.
