Frequently Asked Questions - LF4719 TRISTAR

How to set the desired humidity level?

Press the humidity level button to increase the value between 45 and 90%. The display blinks for 5 seconds then shows the ambient humidity. When the level reaches the set value, the unit stops automatically for 5 minutes before retesting. For continuous operation, set above 90%.

How to activate warm mist?

Press the warm mist button to turn this function on/off. Water is preheated to eliminate bacteria before vaporization. The mist becomes warm after a few minutes, never very hot. The warm mist icon is displayed on the screen.

What water to use in the humidifier?

It is recommended to use soft water (distilled or low mineral content) to minimize limescale deposits on the transducer. Never add perfumes, essential oils, or alkaline substances to the water.

How to clean the transducer?

If limescale deposits appear, clean the transducer with white vinegar and a soft brush, then rinse with clean water. Regular cleaning extends the life of the appliance.

What to do if the 'empty tank' light comes on?

The empty water tank icon appears when the tank is empty. Turn off the appliance, unplug it, fill the tank with clean water (max 40°C) and place it back on the base before restarting.

How to use the ionizer (ozone) function?

When the humidifier is running, press the Ozone button to turn the ionizer on/off. The corresponding icon is displayed. Negative ions help purify the air by removing pollen, dust, and other allergens.

How to set the timer?

Press the Timer button to select a duration from 1 to 12 hours in 1-hour increments. The set time is displayed. Once the time elapses, the humidifier stops automatically. The unit also stops if the target humidity is reached earlier.

What are the important safety precautions?

Place the appliance on a flat surface, at least 15 cm from walls and away from heat sources. Do not use if the cord is damaged. Never disassemble the base. Do not direct mist toward furniture or electronic devices. Always unplug before cleaning.

Where to place the humidifier in a room?

Place the humidifier on a solid, flat surface, at least 15 cm from walls. Avoid sunny areas or near heat sources. Do not direct the mist outlet toward furniture, electronic devices, or baby beds.

How to know when to clean the ceramic filter?

Clean the filter approximately every 600 liters of water (about 100 full tanks). Unscrew the filter, immerse it in white vinegar for 15 minutes, shake it, rinse with clean water, and screw it back on.

USER MANUAL LF4719 TRISTAR

1.1 Intended Purpose

Young children commonly get about 6-8 colds and upper respiratory tract infections each year. Increasing the air moisture is a common way to help your child feel better when he is congested. One thing that makes winter uncomfortable for humans, even inside a nice warm building, is low humidity. People need a certain level of humidity to be comfortable. In the winter, indoor humidity can be extremely low and the lack of humidity can dry out your skin and mucous membranes. Low humidity also makes the air feel colder than it actually is. Dry air can also dry out the wood in the walls and floors of our houses. As the drying wood shrinks, it can cause creaks in floors and cracks in drywall and plaster.

People tend to feel most comfortable at a relative humidity of about 45 percent. The Multifunctional Humidifier 1901W will help to keep indoor humidity at a comfortable level.

This humidifier has a pre-heating function of the water to eliminate bacteria and viruses.

1.2 Safety advice

• Always read the user guide instructions carefully before using the device
• Keep this User's Manual for future reference.
• Always put the humidifier on a hard, flat horizontal surface, at least 15cm from the walls and away from any source of heat such as burners, radiators etc. The humidifier cannot operate on a surface that is not horizontal.
• Keep the humidifier out of reach of children. Do not permit children to play with it.
• Before using the humidifier, unwind the cord and check if it is not damaged. Do not use it if the cord is damaged.
• Do not plug or unplug the humidifier with wet hands.
• Never disassemble the basic unit.
• Never operate the humidifier with a defective plug or cord, or after a breakdown or damage of any kind. In these cases, return the appliance to the nearest approved dealer/repairer for verification and any necessary repairs or adjustments.
• Do not use additives such as perfumes, essences, etc.
• Never add alkaline substances in the water tank.

• Do not shake the humidifier. This could spill water into the base unit and affect its operation.

• Do not leave the humidifier in the sun for a long period.

• If an unusual odour occurs during normal use, turn off the appliance, unplug it and have it verified by qualified personnel.
• Unplug the humidifier before cleaning it or removing the tank.
• Never touch the water or the immersed components when the appliance is in operation.
• Never turn on the humidifier when there is no water in the tank.
• Never scratch the transducer.
• To prevent any damage to the components, do not allow water to splash inside the base unit.
• Never wash the entire unit with water; do not immerse it.
• The Multifunctional Humidifier 1901W should be cleaned regularly. To do this, refer to the cleaning instructions in this manual and respect them.
• Do not use the humidifier if the air in the room is already sufficiently moist (at least 50% relative humidity). Excessive humidity gives rise to condensation on cold surfaces or walls in the room.

When you remove the water tank after usage, there will still be water in the water flume.

Remove the water from the tank and flume when it is not used for a long period.

  Instead of selecting the humidity level 45% to 90% , go one step above 90% for continuous operation.

The ideal comfort RH for a human being is 40 to 60% RH

6.4 Warm mist

If the water gets stagnant, it will spray the stagnant water, and any bacteria it contains, into

your home. This is why it is important to clean the tank regularly and refill it with clean water when you haven't been running it.

6.6 Ionizer (Ozone)

The air ioniser is a device which uses high voltage to ionise, or electrically negative charge, molecules of air. Negative ions (Ozone) help freshen and purify bad particles in the air, which are causing allergens such as pollen, mold spores, dust, and animal dander floating in the air. They help to lift mood, alleviate depression and seasonal affective disorder and promote a sense of well-being.
