Tank MUST BE full of water before power is turned on. Heating ele-
ment(s) WlLL BE DAMAGED if energized for even a short time
while tank is dry. The water heater’s warranty does not cover dam-
age or failure resulting from operation with an empty or partially
empty tank. (Reference is made to the limited warranty for com-
plete terms and conditions.)
4. VACATION AND LONG TIME SHUTDOWN —
If the water heater is installed where it could freeze (summer cabin, lake
home, etc.) you must drain all water from it and the piping. If the tank is full
of water and it freezes, the tank will break.
Freeze damage is not covered
by the warranty!
DRAINING THE WATER HEATER —
Always shut off power to water heater before draining water.
In order to drain water heater, turn off the power supply, then turn off cold
water supply. Next, it is necessary to open a hot water faucet or lift the han-
dle on the relief valve to allow air to the tank, and KEEP OPEN. Attach a
garden hose to the drain valve on the water heater, and open the valve.
Direct the stream of water to a drain where it will do no damage. (See Fig-
ure 16).
The water drained from the tank may be hot enough to present a
SCALD HAZARD and should be directed to a suitable drain to pre-
vent injury or damage.
When preparing to place the water heater in service again, be sure to com-
pletely fill the tank with water before turning the power on.

After a very long shut-down period, the water heater’s operation and con-
trols should should be checked by a qualified service technician.
If water heater has been subjected to flood, fire, or physical dam-
age, turn off power and water to water heater. Do not operate the
water heater again until it has been thoroughly checked by quali-
fied service personnel.
