Replacing and Installing an Energy Smart® Electric Water
Energy Smart® Water Heaters use an electronic control system
which has self-diagnostics and four operating modes including an
energy saving mode. The Energy Smart® Mode setting provides for the
best energy efficiency.
When installing an Energy Smart® Water Heater, the Control Board
must be kept dry. Cover the control board with plastic wrap while
you are making plumbing connections and filling the tank. After the
plumbing connections are complete, but before connecting electric
power, open a hot water faucet (all the way) until the "hot" water
runs FULL STREAM for three minutes. When first opened, you may only
get air out of the faucet, then spurts of water. Wait until the
water runs full and let the water run full for three minutes. Once
you're sure there are no plumbing leaks, remove the plastic wrap
and finish the installation.
If you are replacing the water heater yourself, get an
Installation Kit which contains most everything you'll need to
install the water heater. Most replacements require the use of
common plumbing tools, pipe joint compound or Teflon® tape approved
for potable water. If your house has copper pipes, consider
flexible connectors and compression fittings. For
non-professionals, compression fittings are easier to use than
soldering copper pipe. If you do plan to solder copper pipe, be
aware that the water heater connections may contain non-metallic
parts which can melt. Don't solder copper pipes directly attached
to the water heater. Instead, solder about a foot of pipe to an
adapter and attach the adapter to the inlet and outlet connections.
Then, make your final solder connection about a foot away from the
inlet and outlet fittings, using a wet rag to cool the
You will also need
a circuit tester or volt meter to check for electric power.
The Installation Instructions have a comprehensive Check List.
Make sure you have successfully completed each step before turning
electric power on.
