WEEKLY CLEANING AND MAINTENANCE ADVISORY
At least weekly cleaning is recommended, when the unit has been in use.
Regular cleaning prevents mineral scale buildup in the hot water reservoir. It
also helps prevent buildup of bacteria, molds or other microorganisms in the
tank or system. This ensures that your humidier will operate at maximum
eciency. (See page 6 for full cleaning instructions.)
HOW YOUR ENVIRACAIRE
WARM MIST
HUMIDIFIER WORKS
The model EWM-220 humidier uses a
two-step approach to eliminate potentially
harmful microorganisms from the water
before they are spread with the mist into
the air. The rst step uses a UV bulb, located
inside the base of the humidier, that shines
on the water through a special glass tube
as it passes from the cold water reservoirs
to the hot water reservoir. The second step
is the boiling action that takes place in the
hot water reservoir just before the mist is
distributed to the air in the room.
CONTROL PANEL
POWER SWITCH — ON ( ) POSITION
When the push button switch is pushed to the ON
setting and the unit is plugged in, the power is on.
The green “POWER” indicator light will be illuminated.
OFF POSITION ( ) - When the push button switch
is pushed to the “OFF” position, the “POWER” indicator
light will not be illuminated, indicating that the power
is “OFF”. This should be used (in addition to unplugging
unit) before moving, performing maintenance, etc.
REPLACE UV BULB
If the “REPLACE UV BULB WHEN LIT” signal light is
continuously illuminated during normal use (an
occasional faint glow may occur when switching power
on or other times, but this is normal), the bulb must
be replaced with the same special 3.5W bulb. See
the enclosed order form. The UV bulb will operate at
maximum output for approximately 2,000 hours. The
UV bulb may operate longer than 2,000 hours but at
a reduced output. To keep your humidier operating
at maximum eciency it is recommended that the UV
bulb be replaced after 2,000 hours of use.
