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.
