Honeywell HUL525/545 Series Ultrasonic Cool Mist Humidifier

IMPORTANT SAFETY INSTRUCTIONS

READ AND SAVE THESE SAFETY INSTRUCTIONS BEFORE USING THIS HUMIDIFIER

When using electrical appliances, basic precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons, including the following:

The humidifier should ALWAYS be placed on a firm, flat, waterproof surface at least three feet (1.2m) away from bedside, 12 inches (30cm) from the wall. KEEP OUT OF REACH OF CHILDREN AND PETS.
Be sure the humidifier is in a stable position and the power cord is away from heated surfaces and out of the way to prevent the humidifier from being overturned.
DO NOT leave the humidifier unattended in a closed room. Doing so may result in personal injury or property damage. If room becomes saturated, open the door and turn the humidifier off or down.
Before using the humidifier, extend the cord and inspect for any signs of damage. DO NOT use the unit if the cord has been damaged. DO NOT operate with power cord coiled or with twist tie in place.
The humidifier has a polarized plug (one blade is wider than the other) as a safety feature. This plug will fit into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. DO NOT attempt to defeat this safety feature.
CAUTION: To avoid fire or electric shock hazard, plug the humidifier directly into a 120V AC electrical outlet. To avoid risk of fire, electric shock, or personal injury, NEVER use an extension cord or power strip.
The humidifier should ALWAYS be unplugged and emptied when not in operation or while being cleaned. Turn off and unplug humidifier before moving. DO NOT move or tilt humidifier while it is in operation. Plug and unplug unit with dry hands. NEVER pull by cord.
DO NOT operate the humidifier without water. Turn off and unplug unit when tank is empty.
Humidifier requires regular cleaning. Refer to and follow cleaning instructions.
DO NOT operate outdoors; this humidifier is intended for indoor residential use only.
DO NOT place in direct sunlight, high temperature areas or near computers or sensitive electronic equipment.
DO NOT cover or insert objects into any openings on the unit. DO NOT block intake or output vents.
DO NOT touch the nebulizer while the unit is plugged in, as burns could result.
DO NOT attempt to repair or adjust any electrical or mechanical functions on this humidifier. Doing so will void your warranty.
DO NOT add any essential oils or medications (e.g. Vicks VapoSteam®) into the Base Water Reservoir or Water Tank. Doing so could damage the humidifier and void the warranty.
For Residential Use Only.

GETTING TO KNOW YOUR COOL MIST HUMIDIFIER

How it Works

Water is released from the Water Tank into the Reservoir. A Nebulizer vibrates at ultrasonic frequency, breaking the water into a fine mist. The mist is quietly propelled by a fan up a vertical Mist Chamber to the Mist Outlet where the cool, visible mist enters the room. This humidifier will shut off when the water level is low or when the Tank is removed from the Base.

HUL545 tank is 1 gallon

HUL525 tank is 1/2 gallon

SETTING UP YOUR HUMIDIFIER

Unpack the Humidifier

Keep this Owner’s Manual for reference

Remove packaging materials. Remove twist tie from power cord and extend power cord to full length.
Place on a firm, level, water resistant surface a minimum of 12″ (30cm) from any walls. Mist should be directed away from any walls, bedding and furniture.

Hard Water and White Dust

High mineral content in your water, also known as hard water, may cause a white mineral residue to accumulate on surfaces in the room near the humidifier. This mineral residue is commonly referred to as white dust. The higher the mineral content (hardness) of your water, the greater the potential that an ultrasonic humidifier may produce white dust.
White dust is not a result of a defect or flaw in the humidifier. It is a result of the amount of minerals suspended in the water you are using.
To reduce white dust, use distilled water or a Protec PDC51V2 (PDC51CV2 in Canada) Demineralization Cartridge available through Consumer Relations; see back of this manual.

FILLING/REFILLING

NOTE: Tank should be carried using two hands; one hand on the Tank Handle and the other supporting the bottom of the Tank.
Kaz USA, Inc. will not accept responsibility for property damage caused by water spillage.

⚠ HUL525 holds 1/2 gallon (1.9L) of water and HUL545 holds 1 gallon (3.8L) of water (tank and reservoir combined).

Filling:
ALWAYS turn the the humidifier off before removing the Water Tank.

Remove Water Tank and turn upside down. Remove Tank Cap by turning counterclockwise (left). Fill Tank with cool water. DO NOT fill with warm or hot water.
Replace Tank Cap by turning clockwise (right), aligning arrow to lock symbol. Be sure Gasket is in place.
Place Tank on Base. Water will drain from the Tank into the Reservoir when the Plunger is engaged.

USING YOUR HUMIDIFIER

NOTE: Position humidifier to direct mist output away from walls, furniture and bedding.

With the Power Knob in the OFF position , plug the humidifier into a polarized 120V outlet.
CAUTION: TO AVOID ELECTRIC SHOCK, DO NOT PLUG HUMIDIFIER INTO AN OUTLET WITH WET HANDS.
Turn Power Knob to the right to turn on, then turn to left or right to set desired mist level.
Humidity Level: When a comfortable humidity level is reached, turn Power Knob to a lower setting.
A comfortable humidity level is between 40-60%. Consider using a humidity monitor (not included) to display current room humidity and temperature.

CON DENSATION: If you notice condensation on the walls, windows or around the humidifier, the humidity level is too high. Open doors to the room or turn off humidifier until humidity level drops.

Mist Outlet
This humidifier features a directional Mist Outlet. Use this feature to direct the mist where you want it most. The Outlet will rotate 90º in each direction from front to reduce white dust ingestion in the rear air input vent.

Using The Essential Oil Tray:

This humidifier features an Essentil Oil Tray that can be used with your favorite essential oil for added enjoyment. This is not a diffuser the oil does not come in contact with water and is passively evaporated into the air. Essential oils are not included.

Push and release tray to open.
Add a few drops of essential oil to the Pad.
WARNING: DO NOT POUR ANY LIQUIDS INTO THE MIST OUTLET. DO NOT ADD LIQUID INHALANTS, ESSENTIAL OILS OR ANY ADDITIVES TO THE WATER TANK. DOING SO CAN HAVE ADVERSE EFFECTS ON THE HUMIDIFIER AND VOID THE WARRANTY.
To clean the Essential Oil Tray, gently wipe residue from the Tray. Replacement essential oil pads can be ordered through Consumer Relations; see back of this manual.

Using The Demineralization Cartridge:

This humidifier has been designed to be used with the Protec PDC51V2 or PDC51CV2 Demineralization Cartridge (not included). In hard water areas, use of distilled water or a demineralization cartridge with tap water will help minimize the production of white dust. Cartridges can be ordered through Consumer Relations; see back of this manual.

Daily Maintenance

For best results, use fresh clean water every day.

CLEANING YOUR HUMIDIFIER

To keep your humidifier running efficiently, clean it regularly. Weekly cleaning is recommended. All maintenance should be done in the kitchen or bathroom on a water-resistant surface near a faucet.
To properly clean your humidifier, we recommend the separate processes of Scale Removal and Disinfecting.
These two processes must be performed separately.

Before Cleaning

1. Turn off and unplug humidifier. Never clean the humidifier when it is running.
2. Remove Water Tank and empty completely from the Tank and Base. Remove any accessories from the Water Tank and Base.

Scale Removal

Follow steps 1-2 in Before Cleaning section, then follow the additional steps below.

Pour 2 cups (.5 liters) of undiluted distilled white vinegar into the Water Tank.
Replace Tank Cap and swish vinegar in Tank to coat the inside of the Water Tank.
Place Tank on Base, allowing vinegar to drain into the Water Reservoir. The vinegar will loosen mineral buildup on the Nebulizer, Plunger and in the bottom of the Tank. Soak for 20 minutes.
While soaking, remove the Mist Outlet and wipe with cloth soaked in vinegar.
Remove Water Tank and empty vinegar into sink.
Use a soft cloth or the included Cleaning Brush to gently clean Nebulizer, and all areas in the Reservoir.
NOTE: Nebulizer is fragile. DO NOT apply extreme pressure.
Pour vinegar from the Base into the sink. Pour from the side to avoid leaking into Control Knob. Rinse the Tank and Reservoir with clean water until the smell of vinegar is gone.

CAUTION: DO NOT SUBMERGE BASE IN WATER. DOING SO WILL DAMAGE THE HUMIDIFIER AND VOID THE WARRANTY.

CLEANING YOUR HUMIDIFIER CONTINUED ****

Disinfecting

Before starting the disinfecting process, follow Steps 1-2 in the Before Cleaning section.

NOTE: Bleach may stain clothes. It is recommended to wear rubber gloves during this process to protect your hands.

For HUL525, mix 1/2 tsp of bleach with 1/2 gallon (1.9L) of water. For HUL545, mix 1 tsp of bleach with 1 gallon (3.8L) of water and add to Water Tank.
Replace Tank Cap and swish bleach solution in Tank to coat the inside of the Water Tank.
Place Tank on Base, allowing solution to drain into the Water Reservoir. Soak for 20 minutes.
Remove Water Tank and empty solution into sink.
Pour solution from the Base into the sink. Be sure to pour out of the side of the Base to avoid leaking into the Control Knob. Rinse Tank and Reservoir area with clean water until the smell of bleach is gone.

CAUTION: DO NOT SUBMERGE BASE IN WATER. DOING SO WILL DAMAGE THE HUMIDIFIER AND VOID THE WARRANTY.

END OF SEASON CARE AND STORAGE

Follow the cleaning instructions when the humidifier will not be used for at least one week, or at the end of the season. At the end of the season, remove any accessories from the humidifier. Dry the humidifier completely before storing. DO NOT store with water inside the Water Tank. Pack unit in original carton and store in a cool, dry location.
