Make Electrical Connections; Connecting The Electrical Wires; The Water Heater’s Electrical Requirements - A.O. Smith ProLine XE Installation Instructions And Use & Care Manual

INSTALLATION
Open a hot water faucet and
3
allow the water to run until it
flows with a full stream.
Let the water run full stream
4
for three full minutes.
Close the hot water faucet and
5
replace the aerator.
Check inlet and outlet connec-
6
tions and water pipes for leaks.
Dry all pipes so that any drips
or leaks will be apparent. Repair any
leaks. Almost all leaks occur at connec-
tions and are not a tank leak.
Step 11:
Make electrical
connections
WARNING! Working on an ener-
gized circuit can result in severe injury
or death from electrical shock.
NOTICE! Do not turn electrical power
on unless you are sure all of the air is
out of the tank and the tank is com-
pletely full of water. Although this water
heater is equipped with "Dry Fire" pro-
tection, be certain all air is purged from
the tank before making any electrical
connections.
Be sure the electrical power to
1
the water heater is turned OFF
at the circuit breaker panel (or
remove the circuit's fuses).
Using a non-contact circuit
2
tester, check the wiring to make
certain the power is OFF.
This water heater requires a
3
240/208 VAC single phase 30
amp power supply, at 60Hz.
Check the water heater's data plate
(see figure 23 on page 15) and ensure
that the home's voltage, wiring size
(ampacity) and circuit breaker rating
and type are correct for this water
heater. Refer to the wiring diagram
located on the water heater for the cor-
rect electrical connections. Ensure that
wire sizes, type, and connections
comply with all applicable local codes.
In the absence of local codes, follow
the current edition of the Canadian
Electric Code (CEC).

Remove the cover on the
4
electrical junction box on the
side of the water heater.
Install wiring in an approved
5
conduit (if required by local
codes). Use a UL listed or CSA
approved strain relief to secure the
electrical wiring to the water heater.
Connect the ground wire to
6
the green ground screw.
Connect the home's two
power wires to the water heater's two
power wires. Use suitable wire nuts or
other approved means to make the
power connections.
Replace the junction box

cover and secure with the
screw provided.
WARNING! Be sure cover is secured
to reduce the risk of fire and electric
shock.
