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 Notional Electrical
Code. It is available from some local libraries or can be
purchased from the National Fire Prevention Association,
Batterymarch pork, Quincy, MA 02169 as booklet ANSI/
NFPA 70.
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 a 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. It can be installed in rooms smaller than 10' x 10' x
7' (700cu.ft.) with the installation of a Iouvered door or
a GE ducting kit (see www.geospring.com for details).
Louvers should have 240 square inches (0.15 m2) of
open airflow area or greater. If two louvers are used one
should be near the top of the door.
Place the water heater in such a manner that the air
filter, cover, trim ring and front panels can be removed
to permit inspection and servicing.
The water heater should be installed keeping service in
mind. Moving the water heater or other appliances to
provide service to the water heater is not covered under
warranty.
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: Risk o p ope ty
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 access stairs and solid flooring with
no exposed floor joists.
NOTE: The heat pump operating range is 3S°Fto 120°F
(2°C to 49°0. 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.

Water Heater Temperature Setpoint:
Thewater heater temperature setting strongly impacts the
amount of usablehot water availablefor showers and baths.
Energyconsumption/savingsand efficiencytesting of water
heaters,includingthe GeoSpring
TM,
is performed at a 135°F
(57°0 setting, the averagewater heater setting according to
the Department of Energy. All savingsfor GeoSpring
TM
are
basedon hybrid mode operation at 135°F(57°0.
Safety regulations require a factory setting of 120°Fto 125°F
(49°Cto 52°0 max for all new water heaters.Therefore,if
your water heater is currently set at 130°F(54°0 or above
and your new water heater is installed with a factory set
setpoint of 120°F(49°0,the new water heater may seem to
provide lower capacity than your existingwater heater.
The usercan adjust the temperature setting to meet their
needs. Always read and understand the safety instructions
contained in the users manual before adjusting the
temperature setpoint.
