WARNING
TANKS EQUIPPED FOR ONE TYPE VOLTAGE ONLY. This tank is
equipped for one type of voltage only. Check the rating plate
near the bottom access panel for the correct voltage. DO NOT
USE THIS TANK WITH ANY VOLTAGE OTHER THAN THE ONE
SHOWN ON THE MODEL RATING PLATE. Failure to use the
correct voltage can cause problems which can result in DEATH,
SERIOUS BODILY INJURY OR PROPERTY DAMAGE. If you
have any questions or doubts consult your electric company.
CAUTION
If wiring from the fuse box or circuit breaker box was aluminum
for the old tank, replace it with copper wire. If you wish to reuse
the existing aluminum wire, have the connection at the tank
made by a competent electrician. Contact your local utility to
arrange for a professional electrician.

THERMOSTAT
Each thermostat is factory preset at 120°F to reduce the risk of
scald injury. This setting has proven by experience to be most
satisfactory from the standpoint of operational costs and
household needs.
Tanks installed in Florida require the thermostat(s) to be set at
125°F. If you wish to adjust the settings, see the “Temperature
Adjustment” section of this installation manual.
3. Fill the tank until water runs out an opened hot water faucet.
This will let out air in the tank and the piping. Close the faucet
after the water comes out. You must not turn the electricity on
until the tank is full of water. IF ANY AIR IS LEFT IN THE TOP
OF THE TANK, THE TOP HEATING ELEMENT WILL BURN
OUT RIGHT AWAY.
4. Check all the new water piping for leaks. Fix as needed.
WIRING OF ELEMENT
Determine voltage and wattage from the rating plate attached to
the tank. All external wiring, connection, and overcurrent
protective devices must be provided and installed in accordance
with the latest edition of the National Electrical Code, local codes,
and local utility requirements. The tank must be electrically
“grounded” by the installer. A green ground screw has been
provided on the tank’s junction box.
The grounding electrode conductor shall be of copper,
aluminum, or copperclad aluminum. The material shall be
resistant to corrosion, and shall be of one continuous length
without a splice or joint.
Rigid metal conduit, intermediate metal conduit, or electrical
metallic tubing may be used for the grounding means if conduit
or tubing is terminated in fittings approved for grounding.
FIGURE 5
Flexible metal conduit or flexible metallic tubing shall be
permitted for grounding if all the following conditions are met:
1. The length in any ground return path does not exceed 6 feet.
2. The circuit conductors contained therein are protected by
overcurrent devices rated at 20 amperes or less.
3. The conduit or tubing is terminated in fittings approved for
grounding.
WARNING
Never use this tank unless it is completely full of water.
