160-175°F, the Heater re-set switch will trip and the heaters will automatically switch off . To re-set the Heaters, remove
the heater covers & press the red button on the re-set switch to activate. When the Heaters are in use or switched on, it
will draw up to 3 amps of current. The Heater Cartridge is 200Watts (each side), normally both sides do not switch on
