ELECTRICAL INSTALLATION

WARNING

MAKE SURE ALL INPUT POWER IS OFF OR THAT THE UNIT IS DISCONNECTED FROM THE POWER

SUPPLY BEFORE INSTALLING OR REMOVING ANY PART.

WARNING

BEFORE INSTALLING UNIT (S), CHECK WITH LOCAL POWER COMPANY TO DETERMINE ACTUAL

VOLTAGE AT THE JOB SITE. NEVER PLUG a 208-VOLT UNIT INTO 240 VOLTS OR A 240-VOLT UNIT

INTO 208 VOLTS.

WARNING

BE SURE THE GROUND CONNECTION FOR THE RECEPTICAL IS PROPERLY WIRED. NEVER

CONNECT UNIT TO POWER WITHOUT PROPER GROUND CONNECTIONS. IMPROPER GROUND MAY

RESULT IN SEVERE INJURY OR FATALITY.

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 Conveyor

Belt Speed Control to your desired settings.

OFF-ROTARY- Two off positions are provided so that a single rotation in either direction will result in

the unit being turned OFF.

STANDBY- The standby position reduces the power to the unit to ¼, 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.
