sure relief valve (B).
4. Fill the water heater tank with
freshwater.

WATER HEATER DAMAGE HAZARD!
•
Fill the water heater tank BEFORE turning On the water heater breaker on the 110-volt AC

•
NEVER turn On the water heater breaker on the 110-volt AC master panel while the water
heater tank is empty.
•
To test if the tank is full, turn On a hot water faucet. If water flows from the tap, the water
heater tank is full.
•
Even brief water heater operation with a dry tank WILL damage the heating elements.
•
Warranty replacements will NOT be made on elements damaged in this manner.
