ABSTRACT:
Hot tank washer for cyclically repeated temporary intervals of spray cleaning operation, and controls therefor automatically coordinating operation of the system initiating switch, a heat interruption switch, and a door switch with one another and with other system operations. The heat interruption switch inherently puts the hot tank heating on standby momentarily with no power, incident to the user operating the spray system initiating switch; the spray system comes on under full power, incident to, and only contingent upon, the hot tank heating being first put on standby with no power; the spray system and a washer defogger system are automatically secured from operation, incident to the door switch being operated by opening of an access door allowing new work to be put into the washer.
