RELIEF VALVE

WARNING
Risk of Unit Damage -
pressure rating of the relief valve must not exceed
150 PSI (1.03 kPa), 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 Relief Valves
and Automatic Gas Shut-Off Devices for Hot Water
Supply Systems, ANSI Z21.22, 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 BTUH rating 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 (by gravity) 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.
CAUTION
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
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
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
WARNING
The
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.
F11" fault code during installation: If the unit is
tank with water (see above), then turn the power back
on.
Note: the DRY TANK 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
NOTICE
Do not mis-wire electrical connections. 240VAC or
208VAC must be applied across L1 and L2 wires as
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 a 4-conductor wire is supplied to the water heater,
cap the neutral, and connect the remaining wires as
illustrated.
NOTE REGARDING UTILITY POWER-MANAGEMENT
DEVICES (Sometimes called Peak Load Reduction
Switches):
Some power-management switching devices or even
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:
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.
