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).

cold water connections.
5. Reconnect power supply to water heater.
