If your property has a backflow or a check valve on the
plumbing system, then a thermal expansion tank should
be installed near the water heater to protect it from
damage caused by thermal expansion (See HD Supply
Part # 640585 or 640590).

Turn on main water supply or open ball valve on cold
water inlet and fill tank.
Check flow rate from open faucet (hot water side) until
water runs full flow for three minutes to ensure the tank
is completely full. Tank must be completely full before
connecting electrical power to avoid burning out (dry
firing) the upper heating element.
Connect power using the Installation Instructions and
Use & Care Guide and turn on the circuit breaker to
water heater.
Check all water connections for leaks. Most leaks are
caused by poor connections and not a tank leak.
