2.2 EXTENDED SHUTDOWN
EXTENDED OUTAGE PROCEDURE
If a heater will be out of service for an extended amount of time, use the following procedure to
protect the unit.
SCALD PREVENTION
· Water temperatures over 125ºF (52ºC) will scald and can instantly
cause severe burns or death!
· Children, disabled and elderly are at highest risk of being scalded
· Always test the water temperature by feeling the water prior to
entering a shower, bath, etc.
· Obey all codes regarding temperature set point.
· Contact a licensed plumber or local plumbing authority for
clarication or additional information.
IMPORTANT!
The volume measurement only keeps track of the water volume
that passes through the water heater. For example, if hot water
going to a tub is combined with cold water, the volume computed
would not be representative of the total amount that may have lled
the tub. This could lead to an overow or damage!
*Cold air may enter the unit through the air intake or the exhaust system. Take precaution
for extended shutdowns even if unit is installed indoors in an area that does not allow
direct exposure to freezing temperatures.
*Temperatures at or below 0°C (32°F) can cause permanent damage the unit and/or the
piping system due to freezing.
*After a power outage, all settings return to their factory default values.
