Product Parameters

Product name: Humidifier Rated voltage:220-240V Capacity:5L Product size:219201304mm

Product model:DEM-F800 Rated frequency:50-60Hz Rated power:25W

Operating Principle
Deerma humidifier atomizes water into 1-5m ultrafine particles by using the principle that the ultrasonic wave generates 1.7 million high-frequency oscillations per second, and diffuses water mist into the air through the pneumatic device to achieve the purpose of uniform air humidification. The humidifier can maintain the bedroom at ideal humidity and prevent the generation of static electricity.

Cleaning and Maintenance
1. In order to maintain the optimum performance of the humidifier, clean the sink and water tank of the humidifier regularly. 2. Prevent the transducer and the filter from accumulating dirt, and clean them frequently; it is difficult to clean stubborn dirt after a long time. 3. Before cleaning, power off and disconnect the power plug. When unplugging, hold the power plug tightly instead of pulling the power lead. 4. Do not clean the machine surface with chemical solvents, gasoline, polishing powder and other substances, and do not clean the machine with any detergent freely; it is best to clean with clear water. 5. Use soft cloth for routine cleaning of all parts. If the scale in the sink cannot be removed by routine cleaning, use the detergent produced or supervised by our company. Dissolve the citric acid with 60 hot water (the ratio of water to citric acid is 10mL : 1g), pour it to the scaling part, soak it for 5 minutes, then gently scrub the scaling surface with a brush until the scale is removed. 6. Remove the filter from the water tank lid, soak it in the edible white vinegar for 15 minutes, gently shake dozens of times, and then clean with clear water. The function of the cleaned filter is indistinguishable from the new one. 7. Regularly change the old water in the sink and water tank to keep the humidifier clean. 8. When the machine is not used for a long time, please clean all parts and put them in the original packing box or place them in a dry place after drying.

There is no mist after power-on Cause: Check whether the bottom air inlet screen is blocked by foreign bodies, or whether there is a large amount of scale on the atomizer plate. Solution: Clean the surface of the atomizer plate with clear water, or clear the foreign bodies in the air inlet screen.
A small amount of mist Cause: There is much scale or too much impurity in the water. Solution: Clean the atomizer plate and change clean water.
Abnormal noise Cause: The water in the tank is too little, and the surface is unstable. Solution: Fill the sink with water, and place the humidifier on a firm surface
Note: If the fault cannot be removed after the above phenomenon analysis, please contact the maintenance point or dealer of our company. Non- professional personnel shall not disassemble and assemble the machine.
Tips

Fault Analysis and Removal
Turn on the switch but there is no mist Cause: The power supply is not connected or faulty
Solution: Reconnect the power supply. If the machine still works abnormally, please contact Deerma after-sales service center in time.

About usage: Remove the nozzle cover before filling water into the water tank, turn the water tank upside down and open the water tank lid to fill water, or fill water from the side water filling nozzle, tighten the water tank lid and install the water tank on the base, and then the machine can be used normally.
About the accumulated water in the base: the humidifier scatters the liquid water into water mist by the vibration of the ultrasonic atomizer plate, and the water tank is only a transitional water storage tool. The sinks of all humidifier bases will accumulate water, please feel free to use.

About mist amount adjustment: The humidifier can adjust the fog amount. If there is water around the machine during use, it will indicate that the room humidity is too high. Please adjust the fog amount appropriately.
