Electrical Shock Hazard
Disconnect power before
servicing.
Replace all parts and panels
before operating.
Failure to do so can result in
death or electrical shock.
ELECTRICAL CONNECTIONS
Figure 20: Electrical Connections
If you lack the necessary skills required to properly install
the electrical wiring to this water heater, do not proceed but
have a qualified electrician perform the installation.
When making the electrical connections, always make
sure:
• The voltage and frequency correspond to that specified
on the water heater data plate on the front of the water
heater.
• The electrical supply has the proper overload fuse
or breaker protection. The heater draws less than 7
amps.
• Wire sizes and connections comply with all applicable
codes.
• Wiring enclosed in approved conduit (if required by lo-
cal codes).
• The water heater and electrical supply are properly
grounded.
• This water heater must be “hard-wired” - do not use an
extension cord to supply electrical power to this water
heater.
Note:
The wiring diagram can be found on Page 20. Always
reference the wiring diagram(s) for the correct electrical
connections.
When installing the electrical wiring to the water heater:
1. Shut off the power at the electrical service box.
2. Loosen the screws securing the access panel to the
electrical compartment. (The electrical wiring diagram.
models can be found on the inside of the access panel
at the base of the water heater.) Set the access panel
aside.
3. Connect the electrical supply to the water heater in
accordance with local utility requirements and codes.
Use only a dedicated electrical circuit containing a
properly sized fuse or circuit breaker. Maximum over-
load protection should not exceed 15 amperes.
4. Connect this circuit (directly from the electrical service
box) to an electrical disconnect switch.
5. Ground the water heater by connecting the electrical
service ground wire to the green ground wire (provided).
Note: The power supply to this water heater must be
properly polarized, [120 volts from the hot lead (black) to
ground and 0 volts from the neutral lead (white) to ground]
otherwise, the unit will not operate.
6. After making all electrical connections, completely fill
the tank with water and check all connections for leaks.
Open the nearest hot water faucet and let it run for 3
minutes to purge the water lines of air and sediment
and to ensure complete filling of the tank. The electri-
cal power may then be turned on. See figure 20 for
completed installation.
