RELIEF VALVE
.4,WARNING: Risk unit o amoge-The
pressure rating of the relief valve must not exceed 150
PSI(1.03 kPal, the maximum working pressure of the
water heater as marked on the rating plate.
A new combination temperature and pressure-relief
valve, complying with the Standard for ReliefValves and
Automatic GasShut-Off Devicesfor Hot Water Supply
Systems,ANSI Z2!.22, is supplied and must remain installed
in the opening provided and marked for the purpose on
the water heater. No valve of any type should be installed
between the relief valve and the tank. Local codes shall
govern the installation of relief valves.
The BTUHrating of the relief valve must not be less than the
input rating of the water heater as indicated on the rating
label located on the front of the heater (1 watt=3.412 BTUH).
Connect the outlet of the relief valve to a suitable open drain
so that the discharge water cannot contact live electrical
parts or persons and to eliminate potential water damage.
Piping used should be of a type approved for hot water
distribution. The discharge line must be no smaller than the
outlet of the valve and must pitch downward from the valve
to allow complete drainage (bygravity) of the relief valve
and discharge line.The end of the discharge line should
not be threaded or concealed and should be protected
from freezing. No valve of any type, restriction or reducer
coupling should be installed in the discharge line.
ACAUTION:
To reduce the risk of excessive pressures and
temperatures in this water heater, install temperature
and pressure protective equipment required by local
codes and no less than a combination temperature and
pressure relief valve certified by a nationally recognized
testing laboratory that maintains periodic inspection of
production of listed equipment or materials, as meeting
the requirements for Relief Valves and Automatic Gas
Shutoff Devices for Hot Water Supply Systems, ANSI
Z21.22. This valve must be marked with a maximum set
pressure not to exceed the marked maximum working
pressure of the water heater. Install the valve into an
opening provided and marked for this purpose in the
water heater, and orient it or provide tubing so that
any discharge from the valve exits only within 6 inches
above, or at any distance below, the structural floor, and
does not contact any live electrical part. The discharge
opening must not be blocked or reduced in size under
any circumstances.
TO FILL THE WATER HEATER
A WARNING: Risk o funit
D amage-The
tank must be full of water before heater is turned on. The
water heater warranty does not cover damage or failure
resulting from operation with an empty or partially
empty tank.
Make certain the drain valve is completely closed.
Open the shut-off valve in the cold water supply line.
Open each hot water faucet slowly to allow the air to
vent from the water heater and piping.
A steady flow of water from the hot water faucet(s)
indicates a full water heater.
Fl1" fault code during installation:
If the unit is
powered on without a full tank, the error code "Fl1" will
show in the display. Turn off the power, fill the tank with
water (see above), then turn the power back on.
Note: the DRYTANK DETECTION feature on tank is for the
aid of installer and should NOT be used as the primary
control to prevent operation with an empty or partially
filled tank. Power should NEVERbe applied to the water
heater until installer has verified tank is filled and all air
has been purged from system.
NOTICE:
Do not mis-wire electrical connections. 240V AC or 208AC
must be applied across L1 and L2 wires as shown in
'Water heater junction box' illustration. Failure to do so
will VOID the warranty, and can result in 120V applied to
water heater, which may damage the compressor or other
electrical components.
If 4-conductor wire is supplied to the water heater, cap the
neutral, and connect the remaining wires as illustrated.
NOTEREGARDING UTILITYPOWER-MANAGEMENT DEVICES
(Sometimes called Peak Load Reduction Switches):
Some power-management
switching devices or even some
basic timer switches exist that REDUCE voltage from 240V
to 120V during high-electricity-demand
periods. These
devices must be removed from the circuit providing power
to the water heater because of the potential unit damage
noted above.
However, switching devices which cut power from 240V to
0V on a periodic basis are acceptable.
"bAd linE" fault code during installation:
If "bAd linE" is
shown on the display, the unit is not receiving the correct
voltage as a result of incorrect wiring. To correct this fault,
turn the power off to the unit, correct the wiring issue, then
turn the power back on.
