initial operation. Operation of a water heater without a completely filled tank may result in serious damage to the appliance and heating element burn out.

5.The water heater should be connected with a separate grounded branch circuit with over current protection and disconnect switch. The water heater should be grounded in accordance with national and local codes. A ground terminal is provided for ground connection only.

6.Provide the appliance with proper overload protection in the branch circuit. It is suggested that the electrician size the branch circuit at 125 percent of the heater ampere rating and further increase wire size as necessary to compensate for voltage drop in long runs. Branch circuit voltage drop should not exceed 3% at the heater.

7.Voltage applied to the heater should not vary more than +5% to -10% of the model and rating plate marking for satisfactory operation.

8.A wiring diagram is provided with the water heater for the electricians use.

 

CAUTION:

Never turn on the electric

 

 

 

power or attempt to use this electric water heater unless it is completely full of water. Water must flow from the hot water faucet before turning electrical power “ON.” Operation of a water heater without a completely filled tank may result in serious damage to the appliance and heating element burn out

JACKET ASSEMBLY

Outer Jacket – The outer jacket assembly is constructed from steel, galvanized on both sides. The galvanized surface is specially prepared and phosphate coated to allow application of a multiple coat enamel paint process. This coating process insures a long life from the jacket assembly.
