DO NOT DEFEAT THE SAFETY PURPOSE OF THIS POLARIZED PLUG IN ANY WAY.




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 Filter Check Indicator. When the unit is off, the Filter Check Indicator will read in the OFF position. After 60 minutes of use, Filter Check Indicator (refer to fig. 4 for close-up of indicator) will move from the OFF position and indicate your filter condition. A brand Figure 4 new filter will register in the blue section reading GOOD filter. After frequent use of your humidifier, the Filter Check Indicator will let you know when the filter needs to be changed. When the needle is in the red (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 base tray. 3. Discard the old filter and follow weekly cleaning instructions. 4. Insert a new filter into the filter support in the base. 5. Replace the main housing and then the tank. 6. Repeat Operating Instruction steps. It will take about 30 minutes for the humidifier to reach maximum output. You can obtain a new filter by calling 1-800-5-HOLMES in the USA or by visiting your nearest retailer or authorized service center. This humidifier takes model HWF75 replacement filter.

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 automatically start and produce moisture again. A humidity level below 20% can be unhealthy and uncomfortable. The recommended humidity level is between 40% and 50%. 5. When the water level is low, the refill light will illuminate to indicate the unit needs refilling. Shut off and unplug the unit. NOTE: THE FAN WILL CONTINUE TO RUN TO ALLOW THE HUMIDIFIER TO DRY OUT AND PREVENT ALGAE GROWTH. 6. Before refilling, follow Daily Maintenance Instructions. 7. Refill water tanks. 8.

Turn the base upside down, and locate the holes at each of the four corners on the underside. NOTE: You will notice that there are two different shaped wheels. Two of the 4 wheels are stationary wheels and two are swivel type wheels. The stationary wheels are identified by a flat top surface, while the swivel type are curved and include a small plastic piece on the shaft. See figure 1 for installation location for each type of wheel. DO NOT use any tools to install the wheel because tools may damage the base of the unit. Return the base to the upright position. 4.

Thank you for choosing a Holmes Cool Mist console humidifier. To ensure the best performance from your humidifier, please read and save the following instructions.
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.


To Remove Scale: 1. Repeat steps 1-4 above. 2. Partially fill the base with Holmes Cleanse Clean (Model S1710) as instructed on bottle, or with two 8 oz. cups of undiluted white vinegar. Leave this solution in the base for 20 minutes, while cleaning all interior surfaces with a soft brush. Remove base scale by wiping the base with a cloth dampened with undiluted white vinegar. 3. Rinse with clean warm water to remove the cleaning solution before disinfecting the tank. To Disinfect Humidifier Base Tanks: 1. Fill Humidifier Base with 2 gallons of water and 1 teaspoon of chlorine bleach. 2. Fill each tank 1/2 full with water and 1 teaspoon of chlorine bleach. 3. Let the solution stand for 20 minutes, swishing every few minutes. Wet all surfaces. 4. Carefully empty the Base and Tanks after 20 minutes, and rinse with water until you cannot detect any bleach smell. Dry with a clean cloth or paper towel. 5. Depending on the water hardness in your area, it may be necessary to change the filter every 1-2 months. Re-insert the wick filter into the filter support. 6. Refill the water tanks as directed with cool tap water, replace the humidifier housing, and turn the Control Knob to ON.

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. 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.


1. Remove the two tanks from the base of the humidifier and bring each tank to the faucet. Turn the tanks upside down and twist off the tank caps by turning counter-clockwise. Fill each tank with cool, fresh tap water. Replace the cap on each tank FIRMLY. NOTE: Adding a water softening agent like Holmes Water Treatment (Model S-1705) to the water will soften mineral deposits and prevent lime and scale build-up. It will also help prolong the life of the wick filter and make cleaning easier. 2. When full, carry each tank to the humidifier and place onto the base (use both hands when carrying each tank). Each tank holds 2.2 gallons of water, and the base holds 2 gallons of water. WHEN THE TANKS ARE FULL AND PLACED INTO THE BASE, YOU CAN HEAR THE WATER SLOWLY EMPTY INTO THE BASE. When the water stops emptying, remove the tanks and refill each again. Replace the tanks into the base. The WATER LIMITING feature on the tank cap will prevent the tanks from overflowing into the base. YOU NOW HAVE 2.2 GALLONS OF WATER IN EACH TANK AND 2 GALLONS OF WATER IN THE BASE OF THE HUMIDIFIER FOR A TOTAL OF 6.4 GALLONS OF WATER. 3. Plug the power cord into the electrical outlet. Figure 2

Your Holmes Cool Mist humidifier draws dry air through the rear air intake grill area. This air is then passed through a moistureladen 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. NOTE: This humidification system provides a cool, invisible moisture output. It is normal not to see the mist. NOTE: A humidity level below 20% can be unhealthy and uncomfortable. The recommended humidity level is between 40%-50%.
