Safety, energy conservation and hot water capacity are factors
to be considered when selecting the water temperature setting
of the water heater. To comply with safety regulations, the water
temperature setpoint isfactory set at 120°F (49°C).This is the
recommended starting temperature setting.
NOTE:Accordingto USDept of Energy,the average residential
water heater in the USissetat 155°F(57°C).GEGeoSpringm
Hybrid Water Heater'senergy savingsclaimsare basedon a
135°F(57°C)temperature setting.Thewater temperature setpoint
can be raisedfrom the factory setting of 120°Fto 155°F(49°Cto
57°C)without sacrificingthe claimed energy savings.Ifa lower
temperature settingthan 155°F(57°C)isused,greater savingsin
energyand operating costs may be achieved.
See"ToAdjustthe Temperature" section to change the water

des. _ __
This water heater defaults to the Hybrid operating mode.
Available modes are listed below and can be selected using
the IvIODEbutton.
Heat Pump Mode--RECOMMENDED FORMAXIMUMSAVINGS
Heat Pump is the most energy-efficient mode for this water
heater. Ittakes heat from the surrounding air to heat the
water. The time it takes to heat the water is longer in this
mode, so it may not be sufficient if you have a high-demand
situation such us a large household or company.
Hybrid Mode
Hybrid mode combines the energy efficiency of Heat Pump
with the recovery speed and power of the Electric/Standard
mode in most water usage situations. Hybrid mode will allow
the unit to perform like a standard electric water heater while
providing significant energy savings.
NOTE: Reported unit performance, energy consumption
and savings are bused on Hybrid Mode operation at a
temperature setting of !55°F (57°C).
High Demand/Boost
This mode may be necessary if your household has a
higher-than-average water usage or the unit is undersized for
the household water demands. Inthis mode, the unit will use
the electric heating elements only when the water demand
rate is high. When using the heating elements, the water
temperature will recover at a faster rate but it will use more
energy to heat it. Unlike Electric/Standard mode, it will use the
heating elements only when needed, and usethe heat pump
when water demand rates are lower.
Vacation
Thisfeature is used when you will be away from the home for
an extended period of time and hot water is not needed. Inthis
mode, the unit will drop the water temperature down to 50°F
(10°C)and will use the most efficient heating mode to conserve
energy while the heater issitting idle. The unit will automatically
resume heating one day before your return, so that hot water
will be available.
For example if you will be gone 14 days, follow these steps:
1. Select VACATIONby using the Mode button
2. Input total days you will be gone (inthis example, 14) by
pressing the UParrow button (the default is 7days)
3. Press ENTER.
The unit will drop the water temperature down to 50°F (10°C)
for one day less than you will be gone (inthis example, for
13 days).At the end of the day before you return (in this
example, the 13th day),it will automatically return to the
previous operating mode and heat the water to the original
temperature setting so hot water is available upon your
return.
To access any of these modes:
1. Pressthe MODEbutton on the control to the desired
operating mode.
2. The green light will be illuminated on the chosen mode.
NOTE: The difference between Hybrid mode and High
Demand/Boost mode is that in High Demand/Boost mode the
heating resistive elements are activated sooner than in the
Hybrid mode.
Electric/Standard Mode
This mode uses only the upper and lower heating resistance
elements to heat the water, stopping the cool air discharge
during heat pump operation. The time it takes to heat the
water isless in this mode, but it isthe LEASTenergy-efficient
mode.
NOTE: In this mode the green LEDlight will flash after 48
hours as an indication that the unit is not operating in the
most energy efficient mode. The unit will continue to operate
in this mode and does not indicate an operating issue.

Routine Preventive Maintenance
A DANGER: Risk of Scald- Before manually
operating the relief valve, make certain no one will be
exposed to the danger of coming in contact with the hot
water released by the valve. The water may be hot enough
to create a scald hazard. The water should be released into
a suitable drain to prevent injury or property damage.
NOTE: If the temperature and pressure-relief valve on the
hot water heater discharges periodically, this may be due
to thermal expansion in a closed water system. Contact
the water supplier or your plumbing contractor on how to
correct this. Do not plug the relief valve outlet.
Properlymaintained, your water heater will provideyears of
dependable trouble-free service.
It is suggestedthat a routine preventive maintenance program be
establishedand followed by the user.
Temperature and Pressure-Relief Valve:
At least once a year, lift and releasethe lever handle on the
temperature and pressure-reliefvalve,located
on the front-right sideof the water heater, to make certain the
valve operatesfreely.Allow severalgallons to flushthrough the
discharge lineto an open drain.
Periodic Inspection (once a year):
It is further recommended that a periodic inspection of the
operating controls, heating elements and wiring should bemade
byservice personnelqualified inelectric appliance repair.
Mostelectrical appliances, even when new, make somesound
when in operation. Ifthe hissingor singing sound levelincreases
excessively,the electric heating element may requirecleaning.
Contact a qualified installeror plumber for inspection.
Flushing Tank:
A water heater's tank can act as a settling basin for solids
suspended inthe water. Itis therefore not uncommon for hard
water depositsto accumulate in the bottom of the tank. Toclean
the tank of these deposits,follow these steps:
1.Attach a garden hoseto the drain valve located at the bottom
of the unit and direct that hoseto a drain.
2.Open the drain valve with aflat screwdriver.
3.Once afew quarts of water have been drained, close the drain
valve.
This should bedone with the cold water supply open suchthat
water removed through drain valve is replaced,and water supply
flow helpsto removesediment.
Draining the Water Heater
A CAUTION: Risk of Shock- Shut offpowerto
the water heater before draining water.
A DANGER: RiskofScald-Beforemanually
operating the relief valve, make certain no one will be exposed
to the hot water released by the valve. The water drained from
the tank may be hot enough to present a scald hazard and
should be directed to a suitable drain to prevent injury or
damage.
Extended Shutdown Periods or Vacations Exceeding
If the water heater isto remain idlefor an extended period of
time, the power and water to the appliance should be turned
off and the water heater drained to conserve energy and
prevent a buildup of dangerous hydrogen gas. This unit has
no power button, power can only be shut off at the circuit
breaker or disconnect switch.
If the water heater has an anode depletion sensing feature
(some models) and the water heater cannot be drained, it is
recommended to leave the power turned on with the water
heater in vacation mode to ensure that the feature will
continue to operate properly while still conserving energy.
To drain the water heater, follow these steps:
1.Attach a garden hose to the drain valve located at the
bottom of the unit and direct that hose to a drain.
2.Turn off the cold water supply.
3.Admit air to the tank by opening a hot water faucet or
lifting the handle on the relief valve
4. Open the drain valve with a fiat screwdriver.
Note: See page 15for product schematic.

Vacation Node Options
The water heater and piping should be drained if they might
be subjected to freezing temperatures.
After a long shutdown period, the water heater's operation
and controls should be checked by qualified service
personnel. Make certain the water heater is completely filled
again before placing it in operation.
NOTE:Refer to the Hydrogen Gas Caution in the Operating
Instructions (seepage 3).

The water heater and water lines should be protected
from freezing temperatures and high-corrosive
atmospheres. Do not install the water heater in outdoor,
unprotected areas.
A CAUTION: Risko p ope tyDamage-
The water heater should not be located in an area where
leakage of the tank or connections will result in damage
to the area adjacent to it or to lower floors of the
structure. Where such areas cannot be avoided, it is
recommended that a suitable catch pan, adequately
drained, be installed under the water heater. Attic
installations require access stairs and solid flooring with
no exposed floor joists.
NOTE: The heat pump operating range is 3S°Fto 120°F
(2°Cto 49°0. If the ambient temperature is outside of
this range, the heat pump will turn off and the electric

THERMAL EXPANSION
Determine if a check valve exists in the inlet water
line. It may have been installed in the cold water line as
a separate backflow preventer, or it may be part of a
pressure-reducing valve, water meter or water softener.
A check valve located in the cold water inlet line can
cause what is referred to as a "closed water system."
A cold water inlet line with no check valve or backflow
prevention device is referred to as an "open" water
system.
Aswater is heated, it expands in volume and creates
an increase in the pressure within the water system.
This action is referred to as "thermal expansion." Inan
"open" water system, expanding water which exceeds the
capacity of the water heater flows back into the city main
where the pressure is easily dissipated.
A "closed water system," however, prevents the
expanding water from flowing back into the main
supply line, and the result of "thermal expansion" can
create a rapid and dangerous pressure increase inthe
water heater and system piping. This rapid pressure
increase can quickly reach the safety setting of the relief
valve, causing it to operate during each heating cycle.
Thermal expansion, and the resulting rapid and repeated
expansion and contraction of components in the water
heater and piping system, can cause premature failure of
the relief valve, and possibly the heater itself. Replacing
the relief valve will not correct the problem!
Thesuggested method of controlling thermal expansion
isto install an expansion tank in the cold water line
between the water heater and the check valve (refer
to the illustration on page 15).The expansion tank is
designed with an air cushion built in that compresses
as the system pressure increases, thereby relieving the
over-pressure condition and eliminating the repeated
operation of the relief valve. Other methods of controlling
thermal expansion are also available. Contact your
installing contractor, water supplier or plumbing inspector
for additional information regarding this subject.

.4,WARNING: Risk unitoamoge-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 ReliefValvesand
Automatic GasShut-Off Devicesfor HotWater Supply
Systems,ANSIZ2!.22, issupplied 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 reliefvalve and the tank. Localcodes shall
govern the installation of relief valves.
TheBTUHrating of the reliefvalve must not belessthan the
input rating of the water heater as indicated on the rating
label locatedon the front of the heater (1watt=3.412 BTUH).
Connectthe outlet of the relief valveto a suitable open drain
sothat the discharge water cannot contact liveelectrical
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 reliefvalve
and discharge line.Theend of the discharge line should
not be threaded or concealed and should beprotected
from freezing. Novalve of any type, restriction or reducer
coupling should be installed in the discharge line.
TO FILL THE WATER HEATER
A WARNING: RiskofunitDamage-The
tank must be full of water before heater isturned 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 iscompletely 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 (seeabove), then turn the power back on.
Note: the DRYTANKDETECTIONfeature on tank isfor the
aid of installer and should NOTbe 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:
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 ReliefValves 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 sizeunder
any circumstances.
Donot mis-wire electrical connections. 240V ACor 208AC
must be applied across L1 and L2 wires as shown in
'Water heater junction box' illustration. Failure to do so
will VOIDthe 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.
NOTEREGARDINGUTILITYPOWER-MANAGEMENTDEVICES
(Sometimes called Peak Load Reduction Switches):
Some power-management switching devices or even some
basic timer switches exist that REDUCEvoltage 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.

• If the unit has been confirmed to be filled with water, and an Fll code
is experienced, it is possible that the code may be a false indicator due
to certain unique environment conditions encountered during the start
up. Ifthe unit is full of water, turn the breaker off for about 10 minutes
to allow the water temperature to stabilize, then turn the breaker back
on. Ifthe Fll code persists, schedule GE service.
• Call for service or follow the instructions on how to replace the anode
rod on page 14. Ensure that the GEanode depletion sensing anode
rod or other GE approved anode rod is installed. Installation of an
unapproved anode rod will VOID the warranty.
• Contact service. Check anode wire connections if needed.
• The unit will automatically switch to another available mode to en-
sure you continue to have hot water. Contact service immediately and
give them the codes listed on the display screen.
• The heater may switch to another available heating mode. Contact
service immediately. To stop the beeping noise (unless error code F2,
Fll, F17 or bAd linE) press either the UP or DOWN arrow button and the
alarm will stop and the display will go back to normal (set temperature).
• Turn off power to water heater (generally at the breaker panel). Then
read, Electrical Connection section of the Installation Instructions, see
page 17. Then contact the installer to verify electrical input to the water
heater.
• The odor can be reduced or eliminated in most water heaters by
replacing the anode rod with less-active material rod. In some cases,
an added step of chlorinating the water heater and all hot water lines
may be necessary, contact your local water professional or plumber for
options and instructions. Call GE at 1.888.4GE.HEWH (1.888.443.4394)
to learn how to purchase this replacement anode rod. A qualified ser-
vicer or plumber should do this replacement. Use of a non-GE approve
anode rod, or operating the water heater without a GE approved anode
rod will VOID the warranty.
• Check mode of unit.
