the correct replacement by
referring to the water heater’s
data plate for voltage and wa age
informa on.

Clean the threads in the tank
opening with a rag. Insert the
new element equipped with a
rubber gasket. NOTE: Use a drop of
hand dishwashing liquid to lubricate
the gasket to help avoid damaging the
gasket as it is being ghtened. Tighten
with an element wrench.
NOTICE: Do not turn power back on

Refi ll the tank by opening the
cold water supply valve. Make
sure a hot water faucet is
open and the drain valve is closed.
Allow the hot water to run full for at

tank has all the air removed and is
completely full of water. Failure to
perform this step can cause the upper
hea ng element to burn out. Once you
are certain the tank is completely full
of water, close the hot water faucet.

replace the gasket and re-install the
element.
