IMPORTANT SAFETY INSTRUCTIONS

PLEASE READ AND SAVE THESE IMPORTANT SAFETY INSTRUCTIONS
When using electrical appliances, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons, including the following:

  1. Read all instructions before using the appliance.

  2. To avoid fire or shock hazards, plug the appliance directly into a 120V AC electrical outlet.

  3. Keep the cord out of heavy traffic areas. To avoid fire hazards, NEVER put the cord under rugs or near heat registers.

  4. DO NOT place humidifiers near heat sources such as stoves, radiators, and heaters. DO locate your humidifier on an inside wall near an electrical outlet. The humidifier should be at least 4” away from the wall for best results.

  5. NEVER place a humidifier in an area where it is accessible to children. NEVER use a humidifier in a closed room, particularly where a child may be sleeping, resting, or playing (a closed room may result in excessive humidity).

  6. WARNING: Do not attempt to refill the humidifier without first unplugging the unit from its electrical outlet. Failure to heed this warning may cause personal injury. Be sure to unplug the unit by pulling on the plug and not the cord.

  7. Never place anything over the moisture outlet when the unit is running.

  8. NEVER drop or insert any object into any openings.

  9. DO NOT operate any appliance with a damaged cord or plug, after the appliance malfunctions, or if it has been dropped or damaged in any manner. Return the appliance to the manufacturer for examination, electrical or mechanical adjustment, or repair.

  10. Use appliances only for intended household use as described in this manual. Any other use not recommended by the manufacturer may cause fire, electric shock, or injury to persons. The use of attachments not recommended or sold by the manufacturer may cause hazards.

  11. DO NOT use outdoors.

  12. Always place the humidifier on a firm, flat, level surface. A waterproof mat or pad is recommended for use under the humidifier. NEVER place it on a rug or carpet, or on a finished floor that may be damaged by exposure to water or moisture.

  13. DO NOT allow the Moisture Outlet to directly face the wall. Moisture could cause damage, particularly to wallpaper.

  14. The humidifier should be unplugged when not in use.

  15. NEVER tilt, move, or attempt to empty the unit while it is operating.
    Shut off and unplug before removing the water tank and moving the unit.
    THIS PRODUCT IS EQUIPPED WITH A POLARIZED AC (Alternating Current) PLUG (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact qualified personnel to install the proper outlet.
    DO NOT DEFEAT THE SAFETY PURPOSE OF THIS POLARIZED PLUG IN ANY WAY

  16. This humidifier requires daily and weekly maintenance to operate appropriately. Refer to daily and weekly cleaning procedures. Use only cleaners and additives recommended by the manufacturer.

  17. NEVER use detergents, gasoline, glass cleaner, furniture polish, paint thinner, or other household solvents to clean any part of the humidifier.

  18. Excessive humidity in a room can cause water condensation on windows and some furniture. If this happens, turn the humidifier OFF.

  19. Do not use a humidifier in an area where the humidity level is more than 50%. Use a hygrometer, available at your local retailer or through the manufacturer, to measure the humidity.

  20. DO NOT attempt to repair or adjust any electrical or mechanical functions on this unit. Doing so will void your warranty. The inside of the unit contains no user-serviceable parts. All servicing should be performed by qualified personnel only.

  21. Never place housing under water flow or immerse in liquids.

  22. Do not plug in the cord with wet hands: electric shock could result.

  23. Do not pour water in any openings other than the water tank.

  24. To prevent damage to surfaces, do not place the humidifier under overhanging surfaces.

  25. NEVER operate the unit without water in the tank.

  26. Do not move the unit after it has been used until the unit cools completely.

  27. Use both hands when carrying a full tank of water.

PLEASE READ AND SAVE THESE IMPORTANT SAFETY 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.
  • NOTE : DO NOT block air inlet or outlet.

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.

FEATURES

HOW WARM MIST WORKS
Your Holmes Warm Mist humidifier is designed to allow the proper amount of water to flow out of the tank. Air is drawn in through the grill openings located in the back of the unit and mixed with steam in the misting chamber. The warm mist is then dispersed out of the top of the misting chamber through the outlet grill and into the room.

NOTE: A humidity level below 20% can be unhealthy and uncomfortable. The recommended humidity level is between 40%-50%.

PRE-OPERATING INSTRUCTIONS

  1. Be sure the humidifier is switched to OFF and the unit is disconnected from the electrical outlet.
  2. Select a location for your humidifier, on a flat surface, about 4” away from the wall. DO NOT place the humidifier on a finished floor or near furniture, which can be damaged by moisture or water. Place on a moisture-resistant surface.

FILLING THE WATER TANK

  1. Remove the tank from the base of the humidifier and bring to the faucet. Turn the tank upside down and twist off the tank cap by turning counterclockwise. Fill the tank with cool, fresh tap water. DO NOT fill with warm water as this may cause leaking. Replace the tank cap FIRMLY.
  2. When full, carry the tank to the humidifier and place it onto the base. This humidifier holds 1.7 gallons of water in the tank and humidifier base. The tank will immediately begin to empty into the base.
  3. Plug the power cord into a 120V AC electrical outlet.

OPERATING INSTRUCTIONS

Your humidifier is equipped with a technologically advanced AccuSet Plus™ DIGITAL Humidistat. You can set the humidifier to run continuously in manual mode or set the AccuSet Plus™ DIGITALHumidistat to your desired humidity setting. The AccuSet Plus™ DIGITALHumidistat will automatically turn the humidifier ON or OFF, depending on the preset comfort level. The comfort level ranges between 30% and 65% relative humidity.

WARM MIST CLEANING AND MAINTENANCE INSTRUCTIONS

  • The following maintenance procedures must be routinely followed to ensure proper, efficient operation of your humidifier. The unit WILL NOT WORK CORRECTLY if it is not cleaned properly.
  • When the unit is in use, daily and weekly maintenance is recommended. Regular weekly cleaning prevents scale buildup on the heating element and tray. It also prevents microorganisms from growing on the tray and tank. This ensures that maximum efficiency will be achieved.

  6. The Electronic Thermal Control Heating element is lined with a coating that is designed to provide the easiest cleaning and prolong the operating efficiency of the humidifier. DO NOT use any metal or hard objects to clean the Heating Element. Never use detergents, gasoline, kerosene, glass cleaner, furniture polish, paint thinner or other household solvent to clean any part of the humidifier.
