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 humidier will operate at maximum

eciency. (See page 6 for full cleaning instructions.)

HOW YOUR ENVIRACAIRE

WARM MIST

HUMIDIFIER WORKS

The model EWM-220 humidier 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 humidier, 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 humidier operating

at maximum eciency it is recommended that the UV

bulb be replaced after 2,000 hours of use.
