RESETTING THE HIGH LIMIT SWITCH

down. This shut down will occur when water temperatures exceed 190°F(87°C). Power is
automatically turned off to the heating element. The shut off device may activate as a result of a
power outage or an electrical storm.

down the high temperature water inside the heater.
