IMPORTANT SAFETY INFORMATION
o reduce the risk of property
damage, serious injury or death,
T
read and follow the precau ons below,
all labels on the water heater, and
SAFETY
the safety messages and instruc ons
throughout this manual.
RISKS DURING INSTALLATION
AND MAINTENANCE
Electric Shock Risk
Contact with the electrical
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.
• 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
precau ons to
reduce the risk of property damage,
injuries from li ing 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.
• Unit is top heavy, u se an appli-
ance dolly (with strap) to move the
water heater.
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 s how-
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 . Follow manufacturer’s instructions for
installation and adjustment of the
valves.
• The User Interface Module (UIM)
on this water heater have been factory 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) 1½ 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 1½ seconds
155°F (68°C) About 1 second
For informa on about changing the
factory thermostat se ng(s), refer to
the “Adjus ng Temperature” sec on in
this manual (“Step 12” on page 8).
Even if you set the water heater
thermostat(s) to a low se ng, 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 thermostat setting. This temperature variation is the result of your usage pattern and is not a malfunction.
• Water temperature will be hotter 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 temperatures.
• If the water heater is in a hot environment, the water in the tank can
become as hot as the surrounding
air, regardless of the thermostat
setting.
• If 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 fi xtures in the
house, install Thermosta c Mixing
Valves at each point of use.
If anyone in your home is at par cular
risk of scalding (for example, the elderly, children, or people with disabili es) or if there is a local code or state
law requiring a certain water temperature at the hot water tap, then these
precau ons are par cularly important.
6 • Residen al Hybrid Electric Heat Pump Water Heater Use and Care Guide
IMPORTANT SAFETY INFORMATION
According to a na onal standard
American Society of Sanitary Engineering (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 Thermosta c Mixing
Valves, installed at each point of use,
allow you to set the tank temperature
to a higher se ng without increasing
risk of scalds. A higher temperature
se ng allows the tank to provide much
more hot water and can help provide
proper water temperatures for appliances such as dishwashers and washing
machines. Higher tank temperatures
(140°F) also kill bacteria that cause a
condi on 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 contaminate 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:
• D o 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 ignited, and help keep any internal fires
from spreading.
• Keep the water heater from becoming wet. Immediately shut the water
heater off and have it inspected by a
qualified person if you find that the
wiring, thermostat(s) or surrounding 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 properly, 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 laboratory maintains periodic inspection of
the valve production process and certifies that it meets the requirements
for Relief Valves for Hot Water Supply
Systems, ANSI Z21.22. The T&P Relief
Valve’s relief pressure must not exceed
the working pressure rating of the water 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
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 fl ammable.
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 electrical appliances connected to the hot
water system. Do not smoke or have
an open fl ame or other igni on source
near the faucet while it is open.

before you begin work.
If you aren’t sure that you can
safely and properly do this work
yourself, contact a qualifi ed person of
your choice, such as a licensed
plumber or electrician to have the
work done. Improper installa on can
damage the water heater, your home
and other property, and can present
risks of serious injury or death.
Check with your local and
2
state authori es for any local
or state codes that apply to
your area. In the absence of local and
state codes, follow Na onal Fire
Protec on Associa on (NFPA-70) and
the current edi ons of the Na onal
Electric Code (NEC) and the Interna onal Plumbing Code (IPC). The
instruc ons in this manual comply with
na onal codes, but the installer is
responsible for complying with local
codes.
Massachuse s code requires this wa-
ter heater to be installed in accordance
with Massachuse s 248-CMR 2.00 and
248-CMR 5.00: State Plumbing Code.
Other local and state authori es may

INSTALLATION
Follow these steps for proper
installa on:
Step 1:
Verify that your
✓
home is equipped
and up-to-date for
proper opera on
Installing a new water heater is the
perfect me 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 offi cial
for more informa on.
Water pressure
✓
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 pressure 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 water pressure experienced throughout
the day (highest water pressures o en
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 Reducing 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 supply 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
u li es have increased water sup-
ply pressures so they can serve more
homes. In some homes today, pressures 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 appliances connected to the plumbing system,
pay par cular a en on to your home’s
water pressure. When purchasing a
PRV, make sure the PRV has a built-in
bypass.
✓
Water Pressure/
Thermal Expansion
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 illustra on
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 expansion tank contains a bladder and an air
charge. To work properly, the Thermal
Expansion Tank must be sized according to the water heater’s tank capacity
and pressurized to match the home’s
incoming water pressure. Refer to the
installa on instruc ons provided with
the Thermal Expansion Tank for installa on details.
INSTALLATION
Residen al Hybrid Electric Heat Pump Water Heater Use and Care Guide • 9
NOTICE! Water heater must be level!
INSTALLATION
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 backfl ow
preventers and check valves to restrict
water from your home reentering
the public water system. Backfl ow
preventers are o en 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 Expansion Tank.
A Thermal Expansion Tank is a
prac cal and inexpensive way to help
avoid damage to the water heater,
washing machine, dishwasher, ice
INSTALLATION
maker and even toilet valves. If your
toilet occasionally runs for no apparent reason (usually briefl y at night),
that may be due to thermal expansion
increasing the water pressure temporarily.
Water pipe and
✓
tank leaks
Leaks from plumbing pipes or from
the water heater itself can damage
property and could cause a fi re risk.
Figure 8 - A suitable drain pan piped to an
adequate drain can help protect flooring
from leaks and drips.
• Install a suitable drain pan (available at your local plumbing supply
stores ) under the water heater (Figure 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”.
Water tempera-
✓
ture regula on
WARNING! Even if the water heater
thermostat is set to a rela vely low
temperature, hot water can scald.
Install a Thermosta c Mixing Valves at
each point of use to reduce the risk of
scalding (page 6).
BACKGROUND: A Thermosta c Mix-
ing Valve, installed at each pointof-use, mixes hot water from the
water heater with cold water to more
precisely regulate the temperature of
hot water supplied to fi xtures. If you
aren’t sure if your plumbing system
is equipped with properly installed
and adjusted Thermosta c Mixing
Valves at each point where hot water
is used, contact a qualifi ed person for
more informa on.
Step 2:
Verify that the loca on
is appropriate
Before installing your water heater,
ensure that:
The water heater will be:
1
• Installed indoors close to
the center of the plumbing
system.
• In a suitable drain pan piped to an
adequate floor drain or external to
the building (Figure 8).
• In an area that will not freeze
10 • Residen al Hybrid Electric Heat Pump Water Heater Use and Care Guide
Figure 9 - Thermostatic Mixing Valves installed at each point -of-use can help pre-
vent scalds.
Install Thermosta c Mixing Valves
(Figure 9) to regulate the temperature
of the water supplied to each pointof-use (for example, kitchen sink,
bathroom sink, bath, shower). Consult the valve manufacturer’s instruc ons or a qualifi ed person.
• In an area that is suitable for installing the water heater vertically and
on a level surface.
• Install where a typical home appliance sound would not cause a disturbance
• Should not be used for space heating.
NOTICE! Water heater must be level!
INSTALLATION
The loca on has adequate
2
space (clearances) for periodic
servicing. For op mal water
heater effi ciency, the unit must have
unrestricted airfl ow and requires a
minimum installa on 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
