RISKS DURING INSTALLATION
AND MAINTENANCE
Electric Shock Risk
Contact with the electrical
y parts in the Junction box,
behind the access doors
and inside the top shroud can result in
severe injury or death from electrical
shock:
¢ Disconnect power by opening the
circuit breaker or removing the
disconnects before installing or
servicing.
e Use a non-contact circuit tester to
confirm that power is off before
working on or near any electrical
parts.
* Replace the junction box cover and
access doors after servicing.
Lifting Risk
The water heater is
heavy. Follow these
precautions to
reduce the risk of property damage,
injuries from lifting or impact injuries
from dropping the water heater.
® Use at least two people to lift the
water heater.
* Be sure you both have a good grip
before lifting.
se Unit is top heavy, use an appli-
ance dolly {with strap) to move the
water heater.
read and follow the precautions below,
RISKS DURING OPERATION
Scalding Risk
This water heater
can make water hot
enough to cause
severe burns instantly, resulting in
severe injury or death.
¢ Feel water before bathing or show-
ering
¢ To reduce the risk of scalding,
install a Thermostatic Mixing Valve
(temperature limiting valves) at
each point of use. These valves
automatically mix hot and cold
water to limit the temperature at
the tap. Mixing valves are available
at local plumbing supply stores. Fol-
low manufacturer’s instructions for
installation and adjustment of the
valves.
* The User Interface Module (UIM)
on this water heater have been fac-
tory set to approximately 120°F to
reduce the risk of scalding. Higher
temperatures increase the risk of
scalding, but even at 120°F hot
water can scald. If you choose a
higher temperature, installing a
Thermostatic Mixing Valve located
at each point of use are particularly
important to help avoid scalding.
Temperature | Time to Produce a
Serious Burn
120°F (49°C) | More than 5 minutes
125°F (52°C) | 1% to 2 minutes
130°F (54°C) | About 30 seconds
135°F (57°C) | About 10 seconds
140°F (60°C) | Less than 5 seconds
145°F (63°C) | Less than 3 seconds
150°F (66°C) | About 1% seconds
155°F (68°C) | About 1 second
6 * Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide
For information about changing the
factory thermostat setting(s), refer to
the “Adjusting Temperature” section in
this manual (“Step 12” on page 8).
Even if you set the water heater
thermostat(s) to a low setting, higher
temperatures may occur in certain
circumstances:
® In some cases, repeated small
draws of water can cause the
hot and cold water in the tank to
“stack” in layers. If this happens,
the water can be as much as thirty
degrees hotter than the thermo-
stat setting. This temperature varia-
tion is the result of your usage pat-
tern and is not a malfunction.
* Water temperature will be hot-
ter if someone adjusted the
thermostat(s) to a higher setting.
* Problems with the thermostat(s),
or other malfunctions may result in
higher than expected water tem-
peratures.
e |fthe water heater is in a hot envi-
ronment, the water in the tank can
become as hot as the surrounding
air, regardless of the thermostat
setting.
e |f the water supplied to the water
heater is pre-heated (for example,
by a solar system) the temperature
in the tank may be higher than the
water heater's thermostat setting.
To reduce the risk of unusually hot
water reaching the fixtures in the
house, install Thermostatic Mixing
Valves at each point of use.
If anyone in your home is at particular
risk of scalding (for example, the el-
derly, children, or people with disabili-
ties) or if there is a local code or state
law requiring a certain water tempera-
ture at the hot water tap, then these
precautions are particularly important.
According to a national standard
American Society of Sanitary Engineer-
ing (ASSE 1070) and most local plumbing
codes, the water heater’s thermostat
should not be used as the sole means to
regulate water temperature and avoid
scalds.
Properly adjusted Thermostatic Mixing
Valves, installed at each point of use,
allow you to set the tank temperature
to a higher setting without increasing
risk of scalds. A higher temperature
setting allows the tank to provide much
more hot water and can help provide
proper water temperatures for appli-
ances such as dishwashers and washing
machines. Higher tank temperatures
(140°F) also kill bacteria that cause a
condition known as “smelly water” and
can reduce the levels of bacteria that
cause water-borne diseases.
Water Contamination Risk
Do not use chemicals that could con-
taminate the potable water supply. Do
not use piping that has been treated
with chromates, boiler seal, or other
chemicals.
Fire Risk
To reduce the risk of a
fire that could destroy
your home and serious-
ly injure or kill people:
* Do not store things that can burn
easily such as paper or clothes next
to the water heater.
* Be sure the junction box cover and
the access door covers are in place.
These covers keep debris from
entering and potentially being ignit-
ed, and help keep any internal fires
from spreading.
® Keep the water heater from becom-
ing wet. Immediately shut the water
heater off and have it inspected by a
qualified person if you find that the
wiring, thermostat(s) or surround-
ing insulation have been exposed to
water in any way (e.g., leaks from
plumbing, leaks from the water
heater itself can damage property
and could cause a fire risk). If the
water heater is subjected to flood
conditions or the thermostat(s) have
been submerged in water, the entire
water heater must be replaced.
* Make electrical connections prop-
erly, according to the instructions
on page 17. Use 10 gauge solid
copper wire. Use a UL listed or CSA
approved strain relief. Connect
ground wire to green ground screw.
Explosion Risk
High temperatures and
pressures in the water
heater tank can cause an
explosion resulting in property
damage, serious injury or death. A
new Temperature and Pressure (T&P)
Relief Valve is included with your water
heater to reduce risk of explosion by
discharging hot water. Additional
temperature and pressure protective
equipment may be required by local
codes.
A nationally recognized testing labora-
tory maintains periodic inspection of
the valve production process and certi-
fies that it meets the requirements
for Relief Valves for Hot Water Supply
Systems, ANSI 221.22. The T&P Relief
Valve's relief pressure must not exceed
the working pressure rating of the wa-
ter heater as stated on the rating plate.
Maintain the T&P Relief Valve properly.
Follow the maintenance instructions
provided by the manufacturer of the
T&P Relief Valve (label attached to T&P
Relief Valve) and the procedure on
page 32.
An explosion could occur if the T&P
Relief Valve or discharge pipe is
blocked. Do not cap or plug the T&P
Relief Valve or discharge pipe.
Fire and Explosion Risk if Hot Water is
Not Used for Two Weeks or More
4» CAUTION! Hydrogen gas builds up in
a hot water system when it is not used
for a long period {two weeks or more).
Hydrogen gas is extremely flammable.
If the hot water system has not been
used for two weeks or more, open a
hot water faucet for several minutes at
the kitchen sink before using any elec-
trical appliances connected to the hot
water system. Do not smoke or have
an open flame or other ignition source
near the faucet while it is open.

Review all of the instructions
before you begin work.
If you aren't sure that you can
safely and properly do this work
yourself, contact a qualified person of
your choice, such as a licensed
plumber or electrician to have the
work done. Improper installation can
damage the water heater, your home
and other property, and can present
risks of serious injury or death.
Check with your local and
state authorities for any local
or state codes that apply to
your area. In the absence of local and
state codes, follow National Fire
Protection Association (NFPA-70) and
the current editions of the National
Electric Code (NEC) and the Interna-
tional Plumbing Code (IPC). The
instructions in this manual comply with
national codes, but the installer is
responsible for complying with local
codes.
Massachusetts code requires this wa-
ter heater to be installed in accordance
with Massachusetts 248-CMR 2.00 and
248-CMR 5.00: State Plumbing Code.
Other local and state authorities may
have similar requirements or other
codes applicable to the installation of
this water heater.
Before you start, be sure you
have, and know how to use, the
following tools and supplies:
* Plumbing tools and supplies appro-
priate for the type of water pipes in
your home
* Threaded connectors (Figure 1) for
the cold and hot water pipes
* For homes plumbed with plastic
pipe, use threaded connectors suit-
able for the specific type of plastic
pipe used: CPVC and PEX (cross-
linked polyethylene). Do not use
PVC pipe.

Follow these steps for proper
installation:
Installing a new water heater is the
perfect time to examine your home's
plumbing system and make sure the
system is up to current code standards.
There have likely been plumbing code
changes since the old water heater was
installed. We recommend installing the
following accessories and any other
needed changes to bring your home up
to the latest code requirements.
Use this checklist and inspect your
home. Install any devices you need to
comply with codes and assure that your
new water heater performs at its best.
Check with your local plumbing official
for more information.
We recommend checking your
home's water pressure with a pressure
gauge (Figure 6). Most codes allow a
maximum incoming water pressure of
80 psi. We recommend a working pres-
sure no higher than 50-60 psi.
HOW: Purchase an inexpensive water
pressure gauge available at your local
plumbing supply stores. Connect the
Water Pressure Gauge to an outside
faucet and measure the maximum wa-
ter pressure experienced throughout
the day (highest water pressures often
occur at night).
Figure 6 - Use a Water Pressure Gauge to
make sure your home's water pressure is
not too high.
To limit your home's water pressure:
Locate your home's Pressure Reduc-
ing Valve (PRV) on the main incoming
(cold) water supply line and adjust the
water pressure control to between 50
and 60 psig. If your home does not
have a Pressure Reducing Valve, install
a PRV on the home's main water sup-
ply line and set it to between 50 and
60 psig. Pressure Reducing Valves are
available at your local plumbing supply
stores.
BACKGROUND: Over the years, many
utilities have increased water sup-
ply pressures so they can serve more
homes. In some homes today, pres-
sures exceed 100 psig. High water
pressures can damage water heaters,
causing premature leaks. If you have
replaced toilet valves, had a water
heater leak, or had to repair applianc-
es connected to the plumbing system,
pay particular attention to your home's
water pressure. When purchasing a
PRV, make sure the PRV has a built-in
bypass.
Verify that you have a properly sized
Thermal Expansion Tank (Figure 7). We
recommend installing an expansion
tank if your home does not have one.
Codes require a properly pressurized,
properly sized Thermal Expansion Tank
in almost all homes. (See illustration
on inside front cover.)
Figure 7 - A Thermal Expansion Tank helps
protect the home’s plumbing system from
pressure spikes.
HOW: Connect the Thermal Expansion
Tank (available at your local plumbing
supply stores) to the cold water supply
line near the water heater. The expan-
sion tank contains a bladder and an air
charge. To work properly, the Thermal
Expansion Tank must be sized accord-
ing to the water heater’s tank capacity
and pressurized to match the поте’
incoming water pressure. Refer to the
installation instructions provided with
the Thermal Expansion Tank for instal-
lation details.
Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide * 9
BACKGROUND: Water expands when
heated, and the increased volume
of water must have a place to go, or
thermal expansion will cause large
increases in water pressure (despite
the use of a Pressure Reducing Valve
on the home's main water supply
line). The Safe Drinking Water Act of
1974 requires the use of backflow
preventers and check valves to restrict
water from your home reentering
the public water system. Backflow
preventers are often installed in water
meters and may not be readily visible.
As a result, most all plumbing systems
today are now “closed,” and almost all
homes now need a Thermal Expan-
sion Tank.
A Thermal Expansion Tank is a
practical and inexpensive way to help
avoid damage to the water heater,
washing machine, dishwasher, ice
maker and even toilet valves. If your
toilet occasionally runs for no appar-
ent reason (usually briefly at night),
that may be due to thermal expansion
increasing the water pressure tempo-
rarily.
Leaks from plumbing pipes or from
the water heater itself can damage
property and could cause a fire risk.
Figure 8 - A suitable drain pan piped to an
adequate drain can help protect flooring
from leaks and drips.
e Install a suitable drain pan (avail-
able at your local plumbing supply
stores) under the water heater (Fig-
ure 8) to catch condensation or
leaks in the piping connections or
tank. Most codes require and we
recommend installing the water
heater in a drain pan that is piped
to an adequate drain. The drain pan
must be at least two inches wider
than the diameter of the water
heater. Install the drain pan so the
water level would be limited to a
maximum depth of 1-3/4".
Figure 9 - Thermostatic Mixing Valves in-
stalled at each point -of-use can help pre-
vent scalds.
Install Thermostatic Mixing Valves
(Figure 9) to regulate the temperature
of the water supplied to each point-
of-use (for example, kitchen sink,
bathroom sink, bath, shower). Con-
sult the valve manufacturer's instruc-
tions or a qualified person.
10 * Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide
4h WARNING! Even if the water heater
thermostat is set to a relatively low
temperature, hot water can scald.
Install a Thermostatic Mixing Valves at
each point of use to reduce the risk of
scalding (page 6).
BACKGROUND: A Thermostatic Mix-
ing Valve, installed at each point-
of-use, mixes hot water from the
water heater with cold water to more
precisely regulate the temperature of
hot water supplied to fixtures. If you
aren't sure if your plumbing system
is equipped with properly installed
and adjusted Thermostatic Mixing
Valves at each point where hot water
is used, contact a qualified person for
more information.
Before installing your water heater,
ensure that:
The water heater will be:
e |nstalled indoors close to
the center of the plumbing
system.
e In a suitable drain pan piped to an
adequate floor drain or external to
the building (Figure 8).
e In an area that will not freeze
e In an area that is suitable for install-
ing the water heater vertically and
on a level surface.
* Install where a typical home appli-
ance sound would not cause a dis-
turbance
* Should not be used for space heat-
ing.
ater heater must be level!
The location has adequate
space (clearances) for periodic
servicing. For optimal water
heater efficiency, the unit must have
unrestricted airflow and requires a
minimum installation space of 700
cubic feet. As an example, a room that
has an 8 foot tall ceiling and is 10 feet
long by 8-3/4 feet wide would contain
700 cubic feet.
NOTICE: This Heat Pump Water Heater
may be located within a required mini-
mum of 6” clearance from a wall on
the outlet side, however for future
service considerations, a minimum of
3 feet from any obstruction on the
back, left and right side is recommend-
ed.
The floor can support the
weight of a full water heater.

Avoid locations such as attics,
upper floors, or where a leak
might damage the structure
or furnishings. Due to the normal
corrosive action of water, the tank will
eventually leak. To minimize property
damage from leaks, inspect and
maintain your water heater in accor-
dance with this manuals instructions.
Inspect the drain pan, pipes, and
surrounding area regularly and fix any
leaks found. Drain pans are available at
your local plumbing supply store. Leaks
are frequently in the plumbing system
itself and not the water heater.
The unit cannot be placed into
any type of closet or small
enclosure, unless adequate
provisions are made for air exchange
(vented or louvered doors, etc.).

7 To ensure optimal perfor-
mance and servicability, a
minimum clearance of 6
inches must be maintained from all
sides and 6 inches from the top for
access to the air filter.
Water heaters located in
unconditioned spaces (i.e.,
garages, basements etc.) may
require the water piping, condensate
piping, and drain piping to be insulated
to guard from freezing.
The air filter, condensation
drain and controls must be
easily accessable for opera-
tion and service.
The site location must be
free from any corrosive
elements in the atmosphere
such as sulfer, fluorine, sodium and
chlorine. These elements are found in
aerosol sprays, detergents, bleaches,
air fresheners, paint and varnish
removers, refrigerants and many other
household products. In addition,
excessive dust and lint may effect the
operation of the unit, see the Air Filter
Maintenence section in this manual.
The ambient air temperature
must also be considered when
installing this unit. In Efficiency
Mode the air temperature needs to be
above 45°F/7.2°C and below
120°F/48.8°C for heat pump operation.
If the air temperature falls outside
these upper and lower limits, the
electrical elements will activate to meet
the hot water demand and the heat
pump does not operate in either
Efficiency or Hybrid Mode.

Read each installation step
and decide if you have the
necessary skills to install the
water heater. Only proceed if you can
safely perform the work. If you are
not comfortable, have a qualified
person perform the installation.
Locate the water heater's
circuit breaker and turn it OFF
(or remove the circuit's
disconnects).
On the old water heater,
remove the electrical
junction box access panel.
Using a non-contact circuit tester,
check the wiring to make certain the
power is OFF.
ás WARNING! Working on an ener-
gized circuit can result in severe injury
or death from electrical shock.
Disconnect the electrical
Wires.
Open a hot water faucet and
let the hot water run until it
is cool (This may take 10
minutes or longer).
Figure 11 - Let the hot water run until it is
cool.
£ WARNING! Be sure the water runs
cool before draining the tank to re-
duce the risk of scalding.
Connect a garden hose to
the drain valve and place the
other end of the hose in a
drain, outside, or a bucket. (Note
that sediment in the bottom of the
tank may clog the valve and prevent
it from draining. If you can’t get the
tank to drain, contact a qualified
person.)
Turn the cold water supply
valve OFF.
Open the drain valve on the
water heater.

Figure 13 - Removing the T&P Relief Valve
discharge pipe.
Disconnect the water pipes.
Many water pipes are
connected by a threaded
union which can be disconnected with
wrenches. If you must cut the water
pipes, cut the pipes close to the water
heater's inlet and outlet connections,
leaving the water pipes as long as
possible. If necessary, you can make
them shorter later when you install
2“
the new water heater.
Remove the old water heater.
AH WARNING! Use two or more people
to remove or install water heater.
Failure to do so can result in back or
other injury.
Completely read all instruc-
tions before beginning. If you
are not sure you can complete
the installation, DO NOT RETURN THIS
UNIT TO THE STORE. Schedule an
appointment with a qualified person
to install your water heater.
Install a suitable drain pan
that is piped to an adequate
drain.
Set the water heater in place
taking care not to damage the
drain pan.
NOTICE! Most codes require setting
the water heater in a suitable drain
pan piped to an adequate drain. The
drain pan helps avoid property damage
which may occur from condensation
or leaks in the piping connections or
tank. The drain pan must be at least
two inches wider than the diameter
of the water heater. Install the drain
pan so the water level is limited to a
maximum depth of 1-3/4”.
Verify that the water heater is
set in place properly. Check
that:
* The T&P Relief Valve will not be in
contact with any electrical parts.
* There is adequate space to install
the T&P Relief Valve discharge pipe
and that it can be piped to a sepa-
rate drain (and not into the drain
pan).
* There is adequate space to install
proper condensate drain piping.
* There is adequate access and space
around the water heater for future
maintenance. A minimum clearance
of 6 inches must be maintained
from all sides and 6 inches from the
top for access to the air filter.
* Unitis level to allow proper con-
densate drainage. An unlevel unit
may lead to condensate draining
improperly and resulting in property
damage.
NOTICE! Connecting electrical power
to the tank before it is completely
full of water (Water must run FULL
STREAM from a hot water tap for a full
three minutes) will cause the upper
heating element to burn out.
NOTE: If no floor drain is available or
the drain is above the level of the
condensate line, a condensate pump
must be installed.
Follow condensate drain
pump manufacturers instruc-
tions for installation.
Locate the wire loop inside
the condensate drain access
compartment by removing
the 4 screws attaching the condensate
drain access cover to the unit. Cut the
loop and strip insulation off the 2 ends
(Figures 14 & 15 on page 13 & 14).
Measure the distance from
the condensate drain access
cover to the condensate
pump, and cut two 22 AWG wires to
correct length and strip the insulation
at both ends. Thread both ends
through the grommet on the drain pan
cover.
Connect these 2 wires to the
2 wires on the water heater
using wire nuts or other con-
nectors. Reinstall the condensate drain
access cover and keep the connection
joints inside of the cover.
Connect the free ends of the
2 wires to the shut off switch
on the condensate pump in
accordance with the condensate pump
manufacturers recommendations.

e (Condensate drain lines should
be installed in conditioned areas
only. Install approved insulation
on the condensate drain lines to
prevent condensation from form-
ing on the outside of the drain
lines. Condensation drain lines
installed in areas that are subject
to freezing temperatures should
be wrapped with a nationally
recognized heat tape. Install per
manufacturer's instructions.
e Do not connect condensate
drain lines with other drain or
discharge lines into a single (com-
mon) pipe or line. Each line (con-
densate drain line, temperature
and relief vaive discharge pipe,
etc.) should be independently
run to an adequate drain.
es Slope the condensate drain lines
toward the inside floor drain or

* The condensate drain lines and
connections to the drain piping
must comply with all local codes.
e Use appropriate fittings and
primer to cement the condensate
drains to the heat pump drain
pan.
® |f a condensate pump is installed,
it should be wired to shut off the
heat pump in the event the con-
densate pump fails or the float
witch in the pump activates (see
step 5 on page 13).
Using 3/4” PVC piping, a 90°
elbow that is 3/4” slip & 3/4”
NPT and an approved sealant
(none supplied with unit), attach the
elbow to the primary drain connec-
tion and insert the PVC pipe into the
female end allowing enough length to
access an adequate drain.
Using 1/2” ID rubber or flexi-
ble plastic tubing, slip one
end over the secondary drain
connection allowing enough length to
access an adequate drain.
Most T&P Relief Valves are pre-
installed at the factory. In some cases,
they are shipped in the carton and
must be installed in the opening
marked and provided for this purpose
and according to local codes. .
14 * Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide
6 WARNING! To avoid serious injury
or death from explosion, install a T&P
Relief Valve according to the following
instructions:
If your water heater does not have
a factory installed T&P Relief Valve,
install the new T&P Relief Valve that
came with your water heater. Do not
reuse an old T&P Relief Valve. Install
a T&P Relief Valve discharge pipe ac-
cording to local codes and the follow-
ing guidelines:
The discharge pipe should be
at least 3/4” inside diameter
and sloped for proper
drainage. Install it to allow complete
drainage of both the T&P Relief Valve
and the discharge pipe
The discharge pipe must
withstand 250°F (121°C) with-
out distortion. Use only
copper or CPVC pipe. Most homes
use copper water pipes, but some use
CPVC or cross-linked polyethylene
(PEX). Use fittings appropriate for the
type of pipe in your home. Do not use
any other type of pipe, such as PVC,
iron, flexible plastic pipe, or any type
of hose.
Figure 16 - The T&P Relief Valve discharge
pipe must be installed properly and piped to
an adequate drain.
Terminate the discharge pipe
a maximum of six inches
above a floor drain or outside
the building. Do not drain the dis-
charge pipe into the drain pan; instead
pipe it separately to an adequate
drain. In cold climates, terminate the
discharge pipe inside the building to an
adequate drain. Outside drains could
freeze and obstruct the drain line.
Protect the drain from freezing.
discharge pipe must stop no more than
six inches above a floor drain or outside.
Do not place any valve or
other restriction between the
tank and T&P Relief Valve. Do
not cap, block, plug, or insert any valve
between the T&P Relief Valve and the
end of the discharge pipe. Do not
insert or install any reducer in the
discharge pipe.
If one is not already installed,
install a manual shutoff valve
in the cold water line that sup-
plies the water heater. Install the
shutoff valve near the water heater so
that it is readily accessible. Only use
valves that are compatible with
potable water. Use only full-flow ball
or gate valves. Other types of valves
may cause excessive restriction to the
water flow.
Install a Thermostatic Mixing
Valve at each point of use (for
example, kitchen sink, bath-
room sink, bath,shower). Consult the
valve manufacturer’s instructions or a
qualified person.
Figure 18 - Install Thermostatic Mixing
Valves at each point where hot water
will be used.
A» WARNING! Even if the water
heater's UIM is set to a relatively low
temperature, hot water can scald.
install Thermostatic Mixing Valves at
each point of use to reduce the risk of
scalding.
For water heaters that are fed
by a solar water heating
system (or any other pre-heat-
ing system), always install a Thermo-
static Mixing Valve or other tempera-
ture limiting device in the inlet water
supply line to limit water supply inlet
temperature to 120°F (49°C). Solar
water heating systems can supply water
with temperatures exceeding 170°F
(76.7°C) and may result in water heater
malfunction.
& WARNING! Hot water provided by
solar heating systems can cause severe
burns instantly resulting in severe
injury or death {page 6).
Determine the type of water
pipes in your home. Most
homes use copper water pipes,
but some use CPVC or cross-linked
polyethylene (PEX). Use fittings
appropriate for the type of pipe in your
home. Do not use iron or PVC pipe —
they are not suitable for potable water.
Connect the cold water supply
using 3/4 inch National Pipe
Thread “NPT” to the blue cold
water connection near the bottom of
the heater.
For ease of removing the water heater
for service or replacement, connect
the water pipes with a coupling called
a union. Dielectric type unions are
recommended (available at your
local plumbing supply store). Dielec-
tric unions can help prevent corro-
sion caused by tiny electric currents
common in copper water pipes and
can help extend the life of the water
heater.

Install insulation (or heat tape)
on the water pipes especially
if the indoor installation area
is subject to freezing temperatures.
Insulating the hot water pipes can
increase energy efficiency.
Double check to make sure
the hot and cold water pipes
are connected to the correct
hot and cold water fittings on the
water heater.
If needed, instal! (or adjust)
the home's Pressure Reducing
Valve to 50-60 psig and install
a Thermal Expansion Tank.

Close the hot water faucet and
replace the aerator.
Check inlet and outlet connec-
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.
& 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
the water heater is turned OFF

Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide * 17
The water heater is now ready for
normal operation. To keep your water
heater working safely and efficiently
and extend its life, perform mainte-
nance as described in maintenance
section beginning on page 29.
NOTE: The default operating mode is
Hybrid, to select a different mode see
Operating Modes section on page 19.
PRIOR TO BEGINNING OPERATION:
Air filter is factory installed with tabs
oriented down for shipping. Please see
maintenance section for instructions on
removal, cleaning and replacing.
Turn on electrical power to the
water heater.
NOTICE: The water heater will conduct
a system diagnostic (approximately 8
minutes) each time power is applied
from an off state. Normal operation will
begin after the system diagnostic has
been completed.
Once the diagnostic sequence
has finished, the fan should
turn on. This typically takes 8
minutes, (the User Interface Module will
display “-”, “--", “---” repetitively during
this period).
NOTICE: The heat pump’s fan will not
turn on if the incoming water tempera-
ture is less than 59°F/15°C and/or the
ambient air temperature is above
120°F/15°C, or below 45°F/7.2°C.
Should the internal diagnostics detect a
problem with the heat pump, an error
code will be displayed.
Set the desired operational
mode. For typical installations,
the factory default mode,
Hybrid Mode offers the best combina-
tion of efficiency and hot water delivery.
For detailed descriptions of all opera-
tional modes see “Operating Mode
Descriptions” page 19.
With the installation steps completed,
you may adjust the water heater’s tem-
perature setting if desired.
The water heater’s tempera-
ture setting has been factory
set to approximately 120°F to
reduce the risk of scald injury. You may
wish to set a higher temperature to
provide hot water for automatic
dishwashers or laundry machines, to
provide more hot water capacity, and to
reduce bacterial growth. Higher tank
temperatures (140* F) kill bacteria that
cause a condition known as “smelly
water” and can reduce the levels of
bacteria that cause water-borne
diseases.
4h WARNING! Higher temperatures in-
crease the risk of scalding, but even at
120°F, hot water can scald {page 6).
If you increase the water heater’s tem-
perature setting, install Thermostatic
Mixing Valve(s) at each point of use to
reduce the risk of scalding.
Figure 24 - Adjust Thermostat Mixing
Valves at each point of use to 120°F or
lower.
To adjust the water heater's tempera-
ture setting:
* The water temperature setting can
be adjusted by using the Up and
18 * Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide
Down buttons CA J

up or down buttons, cycle through
the available temperature set points
until the desired temperature is dis-
played. The temperature setting will
blink on the display; press the Mode/
Enter button to confirm the selection
(see figure 26, page 21).
e The available temperature set points
can be cycled through quickly by
pressing and holding the Up button.
Please allow adequate time for
the heater to provide hot
water.
{à WARNING! If you have increased the
temperature setting and the Thermo-
static Mixing Valves are not set prop-
erly (or not installed) you could scald
yourself while checking the tempera-
ture.
Check water temperature at
several points of use in your
home (for example, bathtub
faucet, shower, or lavatory sink) and
adjust the Thermostatic Mixing Valves as
needed. If you aren't sure how to adjust
the Thermostatic Mixing Valve settings,
or aren't sure if you have Thermostatic
Mixing Valves, contact a qualified
person.
Understand how to use the
User Interface Module to set
the various modes and
functions.
Hybrid Mode is the recom-
mended Operating Mode.
Understand the various
Operating Modes and which mode may
be best, based on ambient temperature
and hot water demands.
Understand the importance of
routine inspection/ mainte-
nance of the condensate drain
pan and lines. This is to prevent any
possible drain line blockage resulting in
the condensate drain pan overflowing.
NOTE: If water is coming from the
overflow slot of the condensate drain
access cover, this indicated that both
condensate drain lines may be blocked
and immediate action is required.

The Installation Instructions
and Use and Care Guide should
be kept with the water heater
for reference.
The water temperature can be
adjusted from 95°F / 35°C to 150°F /
65.5°C. Use the Up and Down Buttons
LA | Y | on the front panel to
set the desired temperature (figure 26,
page 21). The setting temperature will
blink on the display, press Mode/Enter
button to confirm.
The water temperature can be adjustec
quickly by pressing the “Temperature
Up” button and holding for three
seconds.
NOTE: Before attempting to adjust
the thermostat, read the “Water
Temperature Regulation” section. If
the instructions are not clear, contact a
qualified person.
NOTE: For increased water demand,
switching (temporarily) to Hybrid
Mode or Electric Mode will decrease
the recovery/re-heat time. Be sure to
switch back to the desired operational
mode when finished.
The operating modes can be changed
sequentially by pressing the Mode/
Enter button (Figure 26, page 21). The
Operation Mode Indication Light will
turn on when the relevant mode is
selected.
This unit is equipped with technology
that senses the hot water demand
from the unit. While in Efficiency or
Hybrid mode, during normal usage,
the unit will operate the heat pump
for maximum efficiency. In the Hybrid
mode during periods when the water
usage is above normal, this unit
has the ability to use one element
(upper or lower) and the heat pump
simultaneously to help improve
recovery. This transition is seamless
and will go unnoticed.
Efficiency Mode -
Provides the highest efficiency and
lowest cost operation by using only
the heat pump for heating. Recovery
time and efficiency will vary with
ambient temperature and relative
humidity. Efficiency will be greatest,
and recovery quickest, when both
are high. At lower temperatures and
relative humidity levels, efficiency
will be lower and recovery will take
longer. Heat pump operation is allowed
between 45°F / 7.2°C to 120°F / 48.8°C
ambient temperature. At ambient
temperatures lower than 45°F / 7.2°C
and greater than 120°F / 48.8°C, the
heat pump will not operate. Similarly,
if the water temperature in the tank is
less than 59°F / 15°C, the heat pump
will not operate. The unit will operate
in electric mode until ambient air and
water temperatures return to the safe
operating range of the heat pump.
Hybrid Mode -
This is the default, recommended
setting, combining high energy
efficiency with reduced recovery time.
This mode uses the heat pump as the
primary heating source. One of the
heating elements (upper or lower)
will provide supplementary heating if
demand exceeds a predetermined level
so that the set point temperature can
be recovered more quickly.
Electric Mode -
The water heater functions as a
conventional electric unit, relying on

The most likely reasons for an electric
water heater to produce NO hot water are:
e No power to the water heater (No lights
on the unit are on).
e Unitin Vacation Mode.
® ЕСО tripped.
e Hot water usage pattern exceeds the
capability of the water heater in current
mode.
« Non-functioning upper temperature
Sensor.
¢ Faulty thermostatic mixing valve.
¢ Leak in plumbing system.
Follow these steps to diagnose and correct
common electrical problems:
Check the electrical power to the
water heater. No hot water is
often caused by a problem with
the homes electrical wiring or circuit
breakers. You'll need a non-contact circuit
tester. Follow these guidlines:
e Locate the water heater's circuit
breaker and turn it off (or remove the
circuit's disconnects).
e Locate the electrical junction box
on the side of the water heater and
remove the cover.
e Identify the two power wires. The
power wires are usually black/black or
black/red-the green or copper wire is
the ground wire.
Figure 28 - Use a non-contact circuit tester
to check for electrical power.
e Turn the circuit breaker back on (or
install the disconnects) and check the
power on both incoming power wires
using a non-contact circuit tester.
e Turn the power off and replace the
cover on the electrical junction box.
If the water heater is not getting power,
contact a qualified person to have your
homes wiring or circuit breakers checked.
Check the upper heating
element. If the water heater is
getting electrical power, check to
see if the upper heating element is burned
out. If the upper element is burned out,
you'll have no hot water. To check the
upper element, you'll need a multimeter
capable of readng resistance.
e Turn the power OFF at the circuit
breaker or remove disconnects.
*e Remove the upper access panel.
® Move the insulation to the side to
access the ECO and heating element.
Check the top two screws of the
ECO using a non-contact circuit
tester and confirm that power is
off { screw terminals 1 and 3 in photo on
next page).
With the electrical power off, remove
the two power wires from the upper
heating element.
Figure 29 - Use a multi meter to check the
resistance of the upper heating element.
Check the resistance of the
upper heating element using a
multimeter. Measure the
resistance between the two screw
terminals on the upper heating element. A
good element will have a resistance
ranging between 5 and 25 Ohms. If the
resistance is:
Outside this range. Replace the element
(see Replacing the Heating Element sec-
tion on page 30). On a new water heater, a
burned out
Within this range. Reattach the power
wires, making sure the wires are in good
condition and the connections are clean
and tight. Next check the following:
Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide * 25
Check/Reset Energy Cut Off
ECO Button.
[Reset Button
Figure 30 - Energy Cut Off (ECO) button
The Energy Cut Off (ECO) shuts off
power to the water heater’s elements
if the temperature of the water in the
tank gets too hot. If the ECO has tripped,
you'll have no hot water. A tripped ECO
can usually be reset, but you should
have a qualified person investigate the
cause of the overheating and repair the
problem. DO not turn the power back
on until the cause of the overheating
has been identified and repaired.
To check the Energy Cut Off (ECO)
e Turn off the power to the water
heater.
& WARNING! Working near an ener-
gized circuit can result in severe injury
or death from electrical shock. Check
power wires in the electrical junction
box with a non-contact circuit tester to
make sure power is off.
e Press the red ECO reset button (see
photo above).
* The ECO was tripped if you hear a
click when it is reset. In most cases a
tripped ECO indicates that the tank
overheated due to a problem with
one of the elements-have a qualified
person check the upper and lower
elements and replace if necessary.
e The ECO was not tripped if you didn't
hear a click. In that case it should be
checked by a qualified person.
e Replace the insulation and the upper
access panel.
e Turn the power back on to the water
heater.
& WARNING! Be sure all covers are
secured to reduce the risk of fire and
electric shock.
A small amount of water dripping from
the Temperature and Pressure (T&P)
Relief Valve usually means the home's
water pressure is too high or you need a
properly sized and pressurized Thermal
Expansion Tank. Refer to Step 1 in the
Installation section of this manual for
more information. A large amount of hot
water coming from the T&P discharge
pipe may be due to the tank overheat-
ing.
4» WARNING! Do not cap or plug the
TEP relief valve or discharge pipe, and
do not operate the water heater with-
out a functioning T&P Relief Valve - this
could cause an explosion.
Water pressure too high. High water
pressure can cause the T&P Relief Valve
to drip. Install a Pressure Reducing Valve
(PRV) on the main cold water supply
line. Adjust the PRV to between 50 and
60 psi.
Thermal Expansion Tank. Install a
Thermal Expansion Tank. If a Thermal
Expansion Tank is already installed and
the T&P Relief Valve discharge pipe
drips, the Thermal Expansion Tank may
be pressurized to the wrong pressure or
the internal bladder may be defective.
Refer to the instructions that came with
the Thermal Expansion Tank for more
information.
26 ¢ Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide
Debris. In rare cases, debris can stick in-
side the T&P Relief Valve preventing the
valve from seating fully. In that case, the
T&P Relief Valve discharge pipe will drip.
You may be able to clear debris from the
T&P Relief Valve by manually operating
the valve, allowing small quantities of
water to flush out the debris. See the
label on the T&P Relief Valve for instruc-
tions.
If the water pressure is between 50
and 60 psi, a Thermal Expansion Tank
is installed and properly pressurized,
and the valve has been cleared of any
debris, and it still drips, the valve may be
broken—have a qualified person replace
the T&P relief valve.
Harmless bacteria normally present in
tap water can multiply in water heaters
and give off a “rotten egg” smell. A high-
er tank temperature setting of 140° kills
the bacteria that causes “smelly water”
and can reduce the levels of bacteria
that cause water-borne disease. A prop-
erly adjusted Thermostatic Mixing Valve
should be installed at each point of use.
In some cases, the standard anode rod
that came with your water heater can be
replaced with a special zinc anode rod
which may help reduce or eliminate the
odor. Contact a qualified person.
NOTE: To protect the tank, an anode rod
must be installed in the water heater at
all times or the warranty is void.
4h WARNING! Because higher tempera-
tures increase the risk of scalding, if you
set the UIM setting higher than 120°F,
Thermostatic Mixing Valves are particu-
larly important {page 4).
ds
During the normal operation of the
water heater, sounds or noises may be
heard. These noises are common and
may result from the following:
* . Normal expansion and contraction
of metal parts during periods of
heat-up and cool-down.
* Sediment buildup on or around
the elements could create varying
amounts of noise and may cause
premature tank failure. Drain
and flush the tank as directed
under the “Draining and Flushing”
section.
e The heat pump compressor or fan
running.
If the water temperature is too hot:
e Adjust the UIM setting on the water
heater (see Step 12 in the installation
section of this manual).
e Install or adjust a Thermostatic
Mixing Valve (see manufacturer's
instructions)
A nonfunctioning thermostat or a short-
ed heating element can cause extremely
hot water. If the Temperature and Pres-
sure Relief Valve (T&P Valve) releases
large amounts of very hot water, it is
likely due to a shorted heating element,
or more rarely a nonfunctioning thermo-
stat, or the thermostat does not fit snug-
gly against the tank. Very high water
temperatures can also cause the Energy
Cut Off (ECO) to trip (see page26). Turn
power off until this problem is fixed.
Check both the cold and hot water at a
sink to determine if the lower pressure
is only on the hot water side. If both hot
and cold faucets have low pressure, call
your local water utility. If the low pressure
is only on the hot water side, the primary
causes of this are:
e Melted dip tube. Soldering copper
pipes while they are connected to the
water heater can melt the inside of the
hot and cold water connections or the
dip tube (cold water side). A melted
dip tube can restrict the flow of hot
water. If that’s the case, replace the dip
tube.
e Partially closed supply valve. Open the
water heater’s supply valve fully.
A WARNING! Because of the increased
risk of scalding, if you set the water
heater's User Interface Module (UIM)
higher than 120°F, Thermostatic Mixing
Valves at each point-of-use are particu-
larly important {page 4).
If the hot water is simply not warm
enough, there are several possible
causes:
e Thermostatic mixing valve faulty or
set too low.
e Temperature set point too low.
e Hot water usage pattern exceeds the
capability of the water heater in cur-
rent mode (See “Operating Mode
Descriptions”).
e Water connections to unit are
reversed (Disconnect and re-install
correctly).
e Leakin plumbing system (Check home
for any leaks and repair).
e Lower heating element not function-
ing properly.
e No power to the water heater (No
lights on the unit are on and dislay is
blank).
e Unit is in Vacation Mode.
e ECO tripped.
e Non-functioning upper temperature
sensor (refer to “Diagnostic Codes”
section E60).
e Air filter dirty (See “Air Filter Mainte-
nance” p.33).
e Out of position outlet j-tube (Assure
orientation of line on tube is in top
position).
e Lower heating element not function-
ing properly.
Thermostatic Mixing Valves. If the
hot water is simply not warm enough,
make sure the faucet you are checking
doesn’t have a defective Thermostatic
Mixing Valve. If these devices fail, they
can reduce the amount of hot water the
shower or faucet delivers even though
there is plenty of hot water in the tank.
Always check the water temperature at
several faucets to make sure the prob-
lem is not in a faucet or shower control.
Residential Hybrid Electric Heat Pump Water Heater Use and Care Guide * 27
User Interface Module (UIM) set too
low. If the water temperature at several
faucets is too cool, adjust the UIM ac-
cording to the instructions in Step 12 of
the Installation section of this manual.
Undersized water heater. If your water
heater runs out of hot water too quickly,
it may be too small for your needs. If the
water heater is old, consider replacing it
with a larger model. If the water heater
is in good condition, you may be able to
meet your families hot water needs with
the existing water heater by installing a
Thermostatic Mixing Valve and then set-
ting the temperature to a higher setting
on the UIM. See “Step 12” on page 16.
You can also reduce your homes hot
water needs by washing clothes in cold
water, installing flow restrictors on
shower heads, repairing leaky faucets,
and taking other conservative steps.
Reversed connections or melted J-tube.
Check the hot and cold connections and
make sure your homes hot water pipe
is connected to the hot water outlet
on the water heater. Usually reversed
connections are found soon after the
installation of a new unit. If copper pipes
were soldered while they were attached
to the water heater, the J-tube may have
melted. The J-tube is a curved plastic
tube inside the tank attached to the cold
water inlet. If the J-tube has melted, it
can be replaced by removing the old
J-tube and installing a new one.
Plumbing leak. Even a small leak in the
hot water side of the homes plumb-
ing system can make it appear that the
water heater is producing little or no hot
water. Locate and repair the leak.
Lower heating element not working.
If the lower heating element is not
working, you will have some hot water
but not as much as before. Because the
lower element does most of the work,
it usually wears out before the upper
element. Replace the lower element if
necessary (see page 30).
Find and turn off the water
heater’s circuit breaker or
remove disconnects.
Find electrical junction box on
side of water heater, remove
cover and identify the two (2)
power wires.
Turn circuit breaker back on (or
re-install the disconnects) and
check for power on both
incoming power wires using a voltmeter.
Again, turn off water heater's
circuit breaker, or remove
disconnect and replace
electrical junction box cover, before
performing maintenance work.

Routine maintenance will help your
water heater last longer and work bet-
ter. If you cant perform these routine
maintenance tasks yourself, call the
Sears Parts & Repair Service Center at
1-800-488-1222 for further assistance.
After the first six months, drain and
flush the water heater and inspect the
anode rod. Depending on the hardness
of your water, repeat this process at
least annually, or more frequently if
needed. From time to time you may
need to replace a heating element or
a thermostat. All three maintenance
tasks are described below
Tap water contains minerals that can
form lime deposits on heating ele-
ments or sediment in the bottom of
the tank. The amount of lime deposits
or sediment depends on the hardness
of your tap water. The rate at which
sediment builds up depends on water
quality and hardness in your area,
the temperature settings, and other
variables. We recommend draining and
flushing the water heater after the first
six months of operation to determine
the amount of sediment build up.
Draining sediment extends the life of
the tank, heating elements, and drain
valves.
e |n areas with very hard water,
remove and check the heating
elements whenever you drain
the tank. If you have heavy lime
deposits on heating elements,
vou will need to replace them
more often.
¢ Sediment may form large masses that
can prevent the tank from draining.
Have a qualified person use a de-lim-
ing agent suitable for potable water
to remove the sediment buildup.
® |n most cases, it is easier and
cheaper to replace lime-encrusted
elements than trying to remove
heavy lime deposits.
Locate the water heater's
circuit breaker and turn it OFF
(or remove the circuit's
disconnects).

A WARNING! Be sure the water runs
cool before draining the tank to
reduce the risk of scalding.
Connect a garden hose to the
drain valve and place the
other end of the hose in a
drain, outside, or in buckets.
Turn the cold water supply
valve OFF,
Open the drain valve on the
water heater.
Figure 33 - Drain Valve
Open a hot water faucet to
help the water in the tank

NOTICE! DO NOT turn electrical power
back on unless the tank is completely
full of water. This is an additional pre-
caution to protect the elements against
dry fire. Dry fire occurs when power is
supplied to the electric elements with-
out sufficient water in the heater. Dry
firing the unit will result in reduced life
of the element or potential immediate
failure of the element. While this unit
is equipped with dry fire protection the
recommended practice is to ensure the
tank is filled with water prior to supply-
ing power to the unit.
Remove and inspect the
anode rod (see Repair Parts
llustration on back cover for
location of the anode rod). Replace the
anode rod if it is depleted.
Figure 34 - Anode Rods from new (top)
to partially depleted (middle) to fully
depleted stages (bottom)

Anode Rod. The anode rod is a sac-
rificial metal rod that helps reduce
corrosion and premature failure (leaks)
in the tank. The anode rod is a consum-
able item. Inspect the anode rod after
the first six months of operation when
you drain and flush the tank. Replace
the anode rod if it is substantially worn
out or depleted. Thereafter, inspect the
anode rod annually or more frequently
if needed. If you use a water softener,
your anode rod will deplete faster than
normal. Inspect the anode rod more
frequently, replacing the anode rod as
needed. (Anode rods are a consumable
item and are not covered under war-
ranty).
If the sediment was present
when the tank was drained,
flush the tank by opening the
cold water supply valve and letting the
water run until no more sediment
drains from the tank. Close the drain
valve when you are done.
NOTICE! Do not turn power back on
until the tank is completely full of wa-
ter. For complete instructions on filling
the tank, follow Step 10 in the Installa-
tion section.
Refill the tank by opening the
cold water supply valve. Make
sure a hot water faucet is
open and the drain valve is closed.
Allow the hot water to run full for at
least three minutes to make sure the
tank has all the air removed and is
completely full of water. Failure to
perform this step can cause the upper
heating element to burn out. Once you
are certain the tank is completely full
of water, close the hot water faucet.
Restore power to the water
heater. It may take two hours
for the tank to heat up.
4 WARNING! Working on an ener-
gized circuit can result in severe injury
or death from electrical shock. Turn
power off. Check wires with a non-
contact circuit tester to make sure
power is off. When you are finished,
be sure all covers are secured to re-
duce the risk of fire and electric shock.
If you are not comfortable replacing a
heating element or thermostat your-
self, have this work done by a qualified
person. To replace the heating ele-
ment, you'll need the following tools
and supplies:

ás WARNING! Be sure the water runs
cool before draining the tank to re-
duce the risk of scalding.
Connect a garden hose to the
drain valve and place the other
end of the hose in a drain or
outside (or use buckets). Turn OFF the
cold water valve that supplies the water
heater. Open the drain valve on the
water heater. Opening a hot water
faucet will help the tank drain faster.
Remove the upper or lower
access panel on the water
heater, and then fold back the
insulation and remove the plastic
element/thermostat cover.
Figure 41 - Access Panel
With the tank drained and
power off, remove the power
wires from the element you
intend to replace.
Remove the bad element
using an element wrench.
Make sure the new element is
the correct replacement by
referring to the water heater’s
data plate for voltage and wattage
information.
Clean the threads in the tank
opening with a rag. Insert the
new element equipped with a
rubber gasket. NOTE: Use a drop of
hand dishwashing liquid to lubricate
the gasket to help avoid damaging the
gasket as it is being tightened. Tighten
with an element wrench.
NOTICE! Do not turn power back on
until the tank is completely full of water.
For complete instructions on filling the
tank, follow Step 10 in the Installation
section.
Refill the tank by opening the
cold water supply valve. Make
sure a hot water faucet is
open and the drain valve is closed.
Allow the hot water to run full for at
least three minutes to make sure the
tank has all the air removed and is
completely full of water. Failure to
perform this step can cause the upper
heating element to burn out. Once you
are certain the tank is completely full
of water, close the hot water faucet.
Figure 42 - Drain Valve
Check the newly installed
element for leaks. If a leak is
present, tighten the element
until the leak stops. If you cannot stop
the leak, drain the tank and remove
the element. Inspect the gasket for
damage. If the gasket is damaged,
replace the gasket and re-install the
element.
Once the element is success-
fully installed and there are no
leaks, replace the power
wires, thermostat cover, insulation,
and access panel. Make sure all wire
connections are tight. Replace the
cover on the electrical junction box.
Restore power to the water
heater. It may take two hours
for the tank to heat up.
4 WARNING! Working on an ener-
gized circuit can result in severe injury
or death from electrical shock. Turn
power off. Check wires with a non-
contact circuit tester to make sure
power is off. When you are finished,
be sure all covers are secured to re-
duce the risk of fire and electric shock.
To replace the ECO, you'll need the fol-
lowing tools and supplies:

Read and follow the operating and
annual maintenance instructions
provided by the manufacturer of the
T&P Relief Valve (yellow label attached
to T&P Relief Valve). Minerals in the
water can form deposits that cause
the valve to stick or create blocked
passages, making the T&P Relief Valve
inoperative. Follow these guidelines:
¢ At least annually, operate the T&P
Relief Valve manually to ensure the
waterways are clear and the valve
mechanism moves freely (below).
Before operating the valve manu-
ally, check that it will discharge in a
place for secure disposal. If water
does not flow freely from the end
of the discharge pipe, turn OFF the
power to the water heater. Call a
qualified person to determine the
cause.
4h WARNING! Hot water will be
released. Before operating the T&P
relief valve manually, check that it
will discharge in a safe place. If water
does not flow freely from the end of
the discharge pipe, turn the power to
the water heater OFF. Call a qualified
person to determine the cause.
Figure 46 - T&P Relief Valve
e At least every five years, have a
qualified person inspect the T&P
Relief Valve and discharge pipe.
Damage caused by corrosive water
conditions, mineral deposits, or
other problems can only be deter-
mined when a qualified person
removes and inspects the valve and
its components.
¢ Note that a dripping T&P Relief
Valve is usually caused by the
home's water pressure being
too high or the lack of a Thermal
Expansion Tank. If your T&P Relief
Valve drips refer to “Drips from T&P
Relief Valve Discharge Pipe” section
on page 26.
