• 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
Hydrogen gas can be produced in a hot water system
that has not been used for a long period of time (usu-
ally two weeks or more). Hydrogen gas is extremely
flammable and can ignite when exposed to a
spark or flame.
To prevent the possibility of injury under these condi-
tions, open the hot water faucet at the nearest sink for
several minutes before using any electrical appliance
connected to the hot water system. If hydrogen gas is
present, you will probably hear a sound like air escap-
ing through the faucet as water begins to flow. DO
NOT SMOKE OR HAVE ANY OPEN FLAME NEAR
THE FAUCET WHEN IT IS OPEN!!
STACKING
Stacking occurs when many short draws of hot water (3
gallons (11.4 liters) or less) are taken from the water heater
tank over a period of time. This results in increased cy-
cling of the water heater which will increase the water
temperature at the hot water outlet. Stacking is a common
phenomenon with storage water heaters. The control sys-
tem in the Watter$aver helps prevent this situation by con-
tinuously monitoring the upper tank temperature.

WATER HEATER MAINTENANCE
CLEANING THE WATTER$AVER
• The air filter should be cleaned at least twice a year
or whenever it is visibly dirty. A dirty filter reduces air
flow to the heat pump’s evaporator coil, resulting in
decreased efficiency. To clean the filter, remove it from
the shroud by pulling it away from the hook fasten-
ers. then vacuum it or wash it in warm water with a
mild soap and pat it dry before replacing it.
• The outer surfaces of the Watter$aver Heat Pump
Water Heater may be cleaned with a sponge and warm
soapy water. Do not use bleach, abrasive cleaners, or
solvents which will damage the unit’s finish.
DRAINING AND FLUSHING
The Watter$aver should be drained completely if being shut
down in freezing temperatures. It is recommended that the
water tank be flushed every 6 months to remove sediment
that builds up during operation. To drain and flush this wa-
ter 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 wa-
ter at low temperatures with minimum energy loss and
prevent the tank from freezing during cold weather.
DANGER
Hot water can produce first degree burns within 3 sec-
onds at 140° F (60° C), 20 seconds at 130° F (54.4°
C), or 8 minutes at 120° F (48.9° 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 disabled
members, or anyone with sensitive skin may require
a lower temperature setting to reduce the risk of scald-
ing.
OPERATIONAL CONDITIONS
WATER ODOR
The water supply system may require special filtration
equipment from a water conditioning company to success-
fully eliminate all water odor problems.
Each Watter$aver contains an anode rod which slowly dis-
sipates while protecting the tank from corrosion. Certain
water conditions will cause a reaction with the rod, the
most common being a “rotten egg smell” caused by hydro-
gen sulfide gas dissolved in the water.
Anode rods made from alternative materials that might elimi-
nate odor problems are also available. Please check with
your supplier for more information.
WARNING
Do not operate the Watter$aver without the anode rod
installed. This will void the warranty.
WATER HEATER SOUNDS
During normal Watter$aver operation, certain noises may
be heard. These noises are common and may result from:
• Operation of compressor and fans.
IMPORTANT: Fan cycling may occur when ambient
temperatures are high.
