Before closing the switch to allow electric current to flow to the water heater, make certain that the water heater is full of water and that the cold water inlet valve is open. Complete failure of the heating elements will result if they are not totally immersed in water at all times. When the switch is closed, the operation of this electric water heater is automatic. Surface mounted thermostats are preset to the “HOT” setting to provide a water temperature of approximately 120°F (49°C) to reduce the risk of scald injury. For water heaters with immersion type thermostats, the temperature control knob located on the side on the control box is factory preset to 120°F (49°C). Care must be taken whenever using hot water to avoid scalding injury. Certain appliances require high temperature hot water (such as dishwashers and automatic clothes washers).
CAUTION
Scalding may occur within five (5) seconds at a temperature setting of 135°F (57°C).
