WATTERSAVER™ HEAT PUMP WATER HEATER

During low demand periods when hot water is not
being used, a lower thermostat setting will reduce
energy loss and may satisfy your hot water needs. If
hot water use is expected to be more than normal, a
higher setting may be required to meet the increased
demand.
When leaving your home for extended periods, turn
the thermostat to its lowest setting. This will maintain
the water at low temperatures with minimum energy
loss and prevent the tank from freezing during cold
weather.
NOTE:
Temperature settings beyond the black indica-
tor will result in decreased efficiency, due to increased
operation in electric resistance mode.

WATER ODOR
The water supply system may require special filtra-
tion equipment from a water conditioning company to
successfully eliminate all water odor problems.
STACKING
Stacking occurs when many short draws of hot wa-
ter (3 gallons or less) are taken from the water heater
tank over a period of time, this results in increased
cycling of the water heater which will increase the
water temperature at the hot water outlet.
Adjusting the thermostat past the “MEDIUM” set-
ting on the dial will increase the risk of scald
injury.
DANGER
!
!
Hydrogen gas can be produced in a hot water sys-
tem that has not been used for a long period of
time (usually two weeks or more). Hydrogen gas
is extremely flammable and can ignite when ex-
posed to a spark or flame.
To prevent the possibility of injury under these
conditions, open the hot water faucet at the near-
est sink for several minutes before using any elec-
trical appliance connected to the hot water sys-
tem. If hydrogen gas is present, you will prob-
ably hear a sound like air escaping through the
faucet as water begins to flow.
Do not smoke or have any open flame near the
faucet when it is open!!!
DANGER
!
!
Do not operate the WatterSaver
TM
without the
anode rod installed. This will void the warranty.
OPERATIONAL CONDITIONS
Each WatterSaver
TM
contains an anode rod which
slowly dissipates while protecting the tank from
corrosion. Certain water conditions will cause a
reaction with the rod, the most common being a
“rotten egg smell” caused by hydrogen sulfide
gas dissolved in the water.
WATER HEATER SOUNDS
During normal WatterSaver™ operation, certain
noises will be heard. These noises are common and
may result from:
• Operation of compressor and fans.
IMPORTANT: Fan cycling may occur when am-
bient temperatures are high.
• Normal expansion/contraction of metal parts
during heat-up and cool-down.
• Sediment build-up on the tank bottom or scale
and mineral deposits on the heating elements.
DANGER
!
!
Hot water can produce first degree burns within
3 seconds at 140
o
F (60
o
C), 20 seconds at 130
o
F
(54
o
C), or 8 minutes at 120
o
F (49
o
C).
Installing an anti-scald device in the hot water
supply line will reduce the risk of scald injury.
Households with small children, elderly or dis-
abled members, or anyone with sensitive skin
may require a lower temperature setting to reduce
the risk of scalding.
