Water Heater Operation with
an Electric Element on 120 Volt
Power
1. Check for the proper voltage supply (120 Volts).
2. Make sure the water heater is full of water and is not
bypassed.
3. Turn on the switch to the electric element. The water
heater will control the temperature.
Pressure Relief Valve
The temperature and pressure relief
valve is located on the exterior of the
water heater. It is designed to open
if the temperature of the water within
the heater reaches 210° F, or if the
water pressure in the heater reaches
150 pounds.
Recreational vehicle water systems are closed systems,
and during the water heating cycle, the pressure build-
up in the water system may reach 150 pounds. When
this pressure is reached, the pressure relief valve will
open and water will drip from the valve. This dripping will
continue until the pressure is reduced below 150 pounds,
and the valve closes. This condition is normal and does
not indicate a defective relief valve.
