des. _

This water heater defaults to the Hybrid operating mode.
Available modes are listed below and can be selected using

the MODEbutton.

Heat Pump (only) Mode--RECOh4h4ENDED FOR HAXIh4Uh4

SAVINGS

Heat Pump (only) isthe most energy-efifcient mode for this
water heater. It takes 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 sufiicient if you have a high-demand
situation such as a large household or company.

Hybrid Mode

Hybrid mode combines the energy efficiency of Heat Pump
(only)with the recovery speed and power of the Electric (Fan
off)/Standard (Fanoff) 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 based on Hybrid Mode operation at a
temperature setting of !35°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. In this 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 (Fan off) mode, it will
use the heating elements only when needed, and use the 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
(!0°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:

!. Select VACATIONby using the Mode button

2. Input total days you will be gone (in this example, 14) by
pressing the UP arrow button (the default is 7 days)

3. Press ENTER.

The unit will drop the water temperature down to 50°F (!0°C)
for one day less than you will be gone (in this example, for
!3 days). At the end of the day before you return (in this
example, the !3th 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:

!. Press the MODE button 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 isthat in High Demand/Boost mode the

heating resistive elements are activated sooner than in the

Hybrid mode.

Electric (Fun off)/Stundurd (Fun off) Mode

This mode uses only the upper and lower heating resistance
elements to heat the water. The time it takes to heat the

water isless in this mode, but it is the LEASTenergy-efficient
mode.

NOTE: In this mode the green LEDlight will flash after 48
hours as an indication that the unti is not operating inthe
most energy efifcient mode. The unit will continue to operate
in this mode and does not indicate an operating issue.

A liance Communication Module (whereinstalled).

The Hybrid Electric heat pump water heater is compatible
with the GESmart Appliance communication module (ACI_

which can be purchased separately. Contact your local utility
or visit www.GEAppliances.com/Smart-Appliance to see if

your area is using ACMtechnology. Applying the ACH allows
the unit to respond to utility signals or to join a home network.

The following demand response features may be available
as part of a pilot test program with the local utility company

to help consumers reduce peak electricity
usage in the home.

INSTALLATION

The ACM module is equipped with magnets in the base
of the module that will enable it to be attached to the painted

metal exterior of the heat pump water heater.

Details on how to connect the cables to the module are
in the instructions that come with the module.

ACMconnector

When the ACM signal is Medium, the control will operate
in Heat Pump (only) Mode and the water temperature

will remain at the current user setting. Ifthe current user
temperature setting is 120°F the screen will display:

Ll

When the
ACM signal is High, the control will operate in Heat Pump

(only) mode, with a water temperature setting of 110°F, and
the screen will display:

When the ACM signal is Critical the control will operate in
Heat Pump (only) mode, with a water temperature setting of

100°F, and the screen will display:

ACMmodule

Once the cable from the ACM module is plugged into the
water heater's connection, follow the power-up directions

included with the ACM module. As soon as the ACM module is
operating, the heat pump water heater is ready to receive the

ACM signals.

QUICK GUIDE

If your local utility company is utilizing ACM technology, the
ACM module will receive the signals sent from your utility

company. One of four signals will be sent:
o "Low" (represents lowest energy cost rate is available)

"Hedium" (represents increased energy cost rate)
"High" (represents increased energy cost rate)

"Critical"(represents "peak rate" energy cost rate)

A heat pump water heater equipped with a ACM module will

automatically recognize what energy cost rate is available
and adjust its mode and temperature setting to use less

energy when rates are medium, high and critical. When the
heat pump water heater responds to these signals, the LED

light above the Power Saver button will be on, indicating
energy pricing periods are in effect, and the letters PSwill

be displayed on the LED if the user attempts to change the
temperature without first pressing the Power Saver override

button.

Notice: Appliance ACM connection carries voltage not
compatible to computers or accessories. Do NOTplug

laptops, modems, touters, etc into the Appliance RJ45
ACM connector. Use only with designated GEAppliance

Accessories. Connection to computers and accessories may
result in product damage.

When unit isoperating in medium, high or critical,the LCDabove
the Power Saverbutton will be lit. If at any time you want to

change the temperature setpoint while the unit isin PowerSaver
mode, pressand hold the Power Saverbutton to override the

Power Saver mode,then use the arrow buttons to change to the
desiredsetting. Override will be in place for 18 hours. Ifyou try

to change the temperature without overriding the powersaver
function, the letters PSwill show on the display,indicating it isstill

in Powersavermode.

When the signal is low or when no ACM module isconnected,
the unit runs as normal. The following steps show how the

unit reacts to Medium, High and Critical signal levels.

Routine Preventive Maintenance

A DANGER:RiskofScald-Beforemanually

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. Thewater 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: ff 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 provide years of

dependable trouble-free service.

It is suggested that 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-relief valve,located

on the front-right sideof the water heater, to make certain the
valve operates freely.Allow several gallons to flush through the

discharge lineto onopen drain.

Periodic Inspection (once a year):
It isfurther recommended that a periodic inspection of the

operating controls, heating elements and wiring should be made

byservice personnel

qualified in electric appliance repair.

Host electrical appliances, even when new, make some sound

when in operation. Ifthe hissingor singing sound levelincreases
excessively,the electric heating element may require cleaning.
Contact a qualified installer or plumber for inspection.

Flushing Tank:

A water heater's tank can act as a settling basin
for solidssuspended in the water. It istherefore not uncommon

for hard water deposits to 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 hose to a drain.

2.Open the drain valve with a flat screwdriver.

3.Once a few quarts of water have been drained, closethe drain
valve.

This should be done with the cold water supply open such that
water removed through drain valve is replaced, and water supply
flow helpsto remove sediment.

Draining the Water Heater

To drain the water heater, follow these steps:

A CAUTION: Risk ofShock- 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 Vacation Mode Options

If the water heater isto remain idle for an extended period of
time, the power and water to the appliance should be turned
off 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.
The water heater and piping should bedrained if they might

be subjected to freezing temperatures.

Installation instructions

The location chosen for the water heater must take into
consideration the following:

LOCAL INSTALLATION REGULATIONS

This water heater must be installed in accordance
with these instructions, local codes, utility codes,

utility company requirements or, in the absence of
local codes, the latest edition of the National Electrical

Code. It is available from some local libraries or can be

purchased from the Notional Fire Prevention Association,
Botterymorch pork, Quincy, MA02169 as booklet ANSI/

NFPA70.

POWER REQUIREMENTS

Check the markings on the rating plate of the water

heater to be certain the power supply corresponds

to the water heater requirements. NOTE: 208V

installations may experience lower performance.

LOCATION

Locate the water heater in o clean dry area as near as
practical to the area of greatest heated water demand.

Long uninsulated hot water lines can waste energy and

water. Unit must be installed in a level location.

NOTE:This unit is designed for any common indoor
installation including: garage, utility room, attic, closet,

etc. With the installation of a Iouvered door, it can

be installed in rooms smaller than 10'x 10' x 7' (700

cu.ft.). Louvers should be 240 square inches (0.15 me)or
greater. If two louvers are used one should be near the

top of the door.

Placethe water heater in such a manner that the air

filter, cover, trim ring and front panels can be removed
to permit inspection and servicing, such as removal of

elements or cleaning of the filter.
The water heater and water lines should be protected

from freezing temperatures and h/jh-corrosive

atmospheres. Do not install the water heater in outdoor,
unprotected areas.

A CAUTION: RiskofProperty Damage-

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 adequate flooring and access stairs.

NOTE: The heat pump operating range is 45°F to 120°F
(7°Cto 49°C). If the ambient temperature is outside of

this range, the heat pump will turn off and the electric
elements will be used until the ambient temperature

returns to within the operating range.

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 isreferred 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 in the

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.
