bEfORE INSTALLING:
for existing home replacements:
• Replacing an existing tank water heater? If your
current water heater has provided adequate hot water,
and no other plumbing changes and/or renovations that
would require additional hot water demand are in process or
planned, then:
• The GeoSpring Hybrid water heater can replace an
equivalent size or smaller standard electric water heater.
• If switching from gas to electric, the GeoSpring Hybrid water
heater may replace the next size smaller gas tank water
heater.
for new construction installation:
*Assumptions for Avg or Low demand household:
- use of standard or low flow shower heads (2.5 gpm/11.4 L per minute or less)
- no showers with multiple shower heads and/or body jets.
- Standard bathtub (no oversized/jetted tubs)
Water Heater Temperature Setpoint:
The water heater temperature setting strongly impacts the
amount of hot water available for showers and baths.
• The average setting of water heaters in the uSA is about
135°F (57°C), so energy consumption/savings and efficiency
testing of water heaters, including the GeoSpring, is
performed at a 135°F (57°C) setting.
• Safety regulations require a factory setting of 120°F to 125°F
(49°C to 52°C) max for all new water heaters. Therefore, if
your water heater is currently set at 130°F (54°C) or above
and your new water heater is installed with a factory set
setpoint of 120°F (49°C), the new water heater may seem to
provide lower capacity than your existing water heater.
• The user can 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.
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 national Fire Prevention Association,
Batterymarch park, 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.
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.
NOTE: This unit is designed for any common indoor
installation including: garage, utility room, attic, closet,
etc. With the installation of a louvered 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 m 2 ) 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 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 high-corrosive
atmospheres . do not install the water heater in outdoor,
unprotected areas.
CAUTION:
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.
