OPERATING INSTRUCTIONS

WARNING!
Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long
period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and
to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink
before using any electrical appliance connected to the hot water system. If hydrogen is present, there will be an
unusual sound such as air escaping through the pipe as the water begins to flow. Do not smoke or use an open flame
near the faucet at the time it is open.
Safety Precautions
A. DO turn off power to water heater if it has been
subjected to overheating, fire, flood or physical
damage.
B. DO NOT turn on water heater unless it is filled
with water
C. DO NOT turn on water heater if cold water supply
shut-off valve is closed.
D. DO NOT store or use gasoline or other
flammable vapors and liquids, such as adhesives
or paint thinner, in the vicinity of this or any other
appliance. If such flammables must be used, open
doors and windows for ventilation.
WARNING!
TURN OFF
the power and water to the water heater if the water heater has been subjected to flood, fire, or physical
damage, turn off power rand water to the water heater.

operate the water heater until it has been thoroughly checked by qualified service personnel.
Safety Controls
The AirTap™ Hybrid Water Heater is equipped with a temperature-limiting control (TCO) that is located above the
primary heating element in contact with the tank surface. If for any reason the water temperature becomes excessively
high, the temperature-limiting control (TCO) breaks the power circuit to the heating element. Once the control opens,
it must be reset manually. Resetting of the temperature limiting controls should be done by a qualified service
technician.
CAUTION:
The cause of the high temperature condition must be investigated by a qualified service technician and corrective
action must be taken before placing the water heater in service again.
NOTE:
Flammable vapors may be drawn by air
currents from surrounding areas to the water
heater.
