How to Get a Better Result of Dehumidification

1. Before using the dehumidifier, please check whether the environmental humidity and temperature have met basic requirements.
   • Operating temperature: 59℉-104℉(15℃-40℃ )
   • Operating humidity: >45%RH
2. Close the doors and windows when you run this room dehumidifier
3. Keep the front air inlet and the back outlet of this electric dehumidifier free from blocking
4. Best for spaces smaller than 450 sq ft, such as living room, bathroom, bedrooms, kitchen, garage, basement, office, RV, etc.

Important Notes:

The effect of this dehumidifier is related to the temperature, the humidity and the size of the room. The more humid, the better effect. The smaller the room, the better effect.

• When you run the dehumidifier in winter, please make sure that the room has enough warmth, which can help the dehumidifier work better, avoid frosting affecting the dehumidification effect.
• If the air temperature is 59℉ (15 ℃), the effect of dehumidification is not obvious, and it will not work 41°F(5℃).
• If the humidity is 60%RH, the dehumidifier usually does not remove 25oz (750ml) a day.

Since the principle of our product is semiconductor dehumidification, so it needs about 2-3 days to see a significant dehumidification effect.

How DOES IT WORK?

The MD751 Dehumidifier works by way of thermoelectric cooling, which uses what's known as the Peltier effect to create a heat flux between the junction of two different types of materials. Using no compressors or moving parts. The device quietly pulls moisture from the air around it. Removing muskiness and dampness from the room.

UNIT OPERATION

1. Device Operation:
   1. After removing the packaging materials, there should be 3 items: A. LONOVE dehumidifier, B. AC/DC power adaptor, C.Drain Pipe
   2. Use the AC power supply. Install the water tank into the dehumidifier; plug the DC power jack of AC/DC power adaptor to the DC Power Socket of the appliance, and then plug the adaptor into the socket outlet.
   3. This dehumidifier has two working modes(Day-mode and Night-mode).
      (1)Press the "ON/OFF" Button to Day-mode, the green indicator light is on and the dehumidification effect is the most powerful, the noise level is between 35-45 dB.
      (2)Long press the "ON/OFF" button to Night-mode, the wind speed LED light is on, the noise level is<35 dB, and the dehumidification effect will be relatively weak.
   4. This dehumidifier will stop the dehumidification automatically when the water reaches the level, the yellow indicator light is on and the green indicator light is flashing when the water tank is full.
   5. When the water tank is full, please cut off the power before pouring and then take out the water tank from the machine. After pouring out the water, put the water tank back to the correct position in the machine.
   6. To switch off the unit, press "ON/OFF" Button. Please unplug the power cord if you do not use the dehumidifier.
2. Description of Indicator lights:
   • Green Light: when the light shows in Green, means the unit is working.
   • Yellow Light is on and Green Light is Flashing: means the water tank is full, reach the water level or the water tank is in a wrong position.
3. Setting Relative Humidity Levels:
   The MD751 Dehumidifier features an advanced humidistat function. You can set your desired relative humidity level in the range of 40%-80%. When RH levels increase beyond your set level by the value of 5% the machine automatically turns on. When RH levels decrease below your set level by a value of 5%, the machine automatically turns off. By default, the unit is set to 50%RH.
   To set your desired level:
   1. Toggle On/Off Switch to On position;
   2. Wait a few seconds until RH Level Display reads the current RH level;
   3. Depress the RH Up/Down Buttons or to select your desired RH level;
   4. The display screen flashes 3 times and then returns to display the current environment RH.
4. How to Install the Drain Pipe:
   1. Pull out the water tank;
   2. Remove the soft rubber plug on the Drain hole;
   3. Connect Drain hole and Drain Pipe.

QUESTIONS AND ANSWERS

1. Will this dehumidifier stop working when temperature under 59℉ (15℃) ?
   When the ambient temperature is lower than 59℉ (15℃), the temperature inside the dehumidifier is less than 41°F (5℃). At this time, the inside of the dehumidifier may freeze or frost, resulting in a poor dehumidification effect, even zero.
2. Does the power cord/adapter get hot when using?
   According to the working principle, the dehumidifier needs the power to operate and the it needs time to dehumidify, the adapter will get warm but can be touched when using. But for your safety, we do not recommend children to touch it.
3. Why is the dehumidification speed so slow? Only collect little water past 8 hours?
   This dehumidifier is an electric semiconductor dehumidifier, it features quiet operation and stable dehumidification effect. Best for household space smaller than 450sq.ft. While other dehumidifiers with compressor are noisy and only for industrial use.
   In general, the water tank will fill up to 80% in 2-3 days in the case of indoor ventilation and humidity > 60%RH.
4. Will it make a very loud noise when using in the bedroom?
   This dehumidifier has two working modes. During normal operation, the noise level is
5. Does it work with 220 voltage?
   Yes. The voltage of this dehumidifier is 110V -240V, it can work with 220 voltage. But the plug type is subject to the country.
6. Can I keep running it all the time?
   Actually, we do not recommend you run it all the time. Please cut off the power cord after 24 hours running and let it rest for at least 10 minutes. That would be better for using lifespan.
