Consumer Safety Information

NOTE: This is an electrical appliance and requires attention when in use.

NOTE: If moisture forms on the walls or windows of the room, turn off the humidifier. The room already has plenty of humidity and additional moisture may cause damage.

Cord and Plug Installation Safety Instructions

The length of cord used on this appliance was selected to reduce the hazards of becoming tangled in, or tripping over a longer cord. If a longer cord is necessary an approved extension cord may be used. The electrical rating of the extension cord must be equal to or greater than the rating of the humidifier (refer to the rating artwork placed on the humidifier). Care must be taken to arrange the extension cord so that it will not drape over the countertop or tabletop where it can be pulled on by children or accidentally tripped over.

PRE-OPERATING INSTRUCTIONS

1.Be sure the humidifier is switched OFF and the unit is disconnected from the electrical outlet.

2.Remove housing, filter and tanks (See Figures 2 and 3).

3.TO PROVIDE ADDITIONAL MOBILITY AND CONVENIENCE TO YOUR CONSOLE HUMIDIFIER, install the wheels. Remove the four wheels located in a small pouch in the box. Turn the base upside down, and locate the holes at each of the four corners on the underside.

OPERATING INSTRUCTIONS

With housing placed properly onto the base, the filter installed correctly, the tanks filled and the plug correctly inserted in the outlet, you are now ready to operate the humidifier.

NOTE: The humidifier produces clean, cool, INVISIBLE moisture. It is normal not to see the moisture.

1.	Switch the Humidity Control Switch to the HIGH
	position and slide the humidistat to HIGH.
2.	Allow up to 30 minutes for the filter to fully absorb
	water and the unit to produce the maximum moisture
	output.
3.	Adjust the 3-speed Humidity Control Knob and the
	Humidistat as desired.
4.	The Automatic Humidistat Control is designed to
	operate between 25% and 60% Relative Humidity
	range. The recommended setting is between 40% and
	50%. When the humidity level in the room is below
	the level you have set, the humidifier will operate to
	produce moisture. When the set humidity level in the
	room is reached, the humidifier will stop. When the
	humidity again drops below the set level, the unit will

REPLACING THE FILTER

Through normal use, waterborne minerals and sediment become trapped in the wick filter. The harder your water, the greater the amount of minerals in the water, and the more often you will need to change your filter.

You will be able to monitor the life of the filter in your humidifier by checking the FilterCheck® Indicator. When the unit is off, the FilterCheck®

Indicator will read in the OFF position.

NOTE: After 60 minutes of use, FilterCheck® Indicator (refer to figure 4 for close-up of indicator) will move from the OFF position and indicate your filter condition.

A brand new filter will register in the section reading GOOD filter. After frequent use of your humidifier, the FilterCheck® Indicator will let you know when the filter needs to be changed.

When the needle is in the CHANGE section, this means the proper amount of moisture is not getting into your air due to the excessive minerals and sediment that have become trapped on your filter. At this point, you should replace your filter. It is important to change your filter as indicated to obtain stated performance level.

To replace the filter, follow the steps below.

1.	Be sure the humidifier is switched OFF and the unit is
	disconnected from the electrical outlet.
2.	Remove the tank and main housing to access the

DO NOT ATTEMPT TO MODIFY THIS PLUG OR DEFEAT THIS

SAFETY FEATURE IN ANY WAY.

HOW COOL MIST WORKS

Your Cool Mist humidifier draws dry air through the rear air intake grill area. This air is then passed through a moisture–laden wick filter, which retains the minerals and deposits in the water. The resulting moist air is directed back into the room from the top air grill.
