This document is the owner's manual for an LG dehumidifier, model MD19GQGE0. It provides comprehensive information on the device's function, safety instructions, operation, smart features, maintenance, and troubleshooting.
Function Description
The LG dehumidifier is designed to remove excess moisture from the air, helping to create a more comfortable and healthy indoor environment. It can be used for general dehumidification, as well as specific tasks like spot dehumidification for drying shoes or laundry. The device incorporates UVnano LED technology, which uses ultraviolet (UV) rays to reduce bacteria in the air, contributing to cleaner air quality. It also features an ionizer function to remove harmful bacteria.
Important Technical Specifications
- Model Name: MD19GQGE0
- Power: AC 220 - 240 V~ 50/60 Hz
- Exterior Dimensions (W x D x H): 415 mm x 296 mm x 715 mm
- Dehumidification Capacity: The manual mentions that dehumidification amount changes according to indoor temperature and relative humidity. It also states that dehumidification is performed with compressor operation only when the desired humidity is lower than the current humidity.
- Installation Requirements: The product must be placed at least 30 cm from walls. It is not ventilated well, the air suction performance will be degraded.
Usage Features
The dehumidifier offers a variety of operational modes and controls:
- Control Panel/Status Display: The device features a control panel with buttons for Start/Stop, Mode, Operation Mode, Humidity Control, Speed, Ionizer, UVnano, and Off Timer. An LED display shows current humidity, desired humidity, and timer settings.
- Operation Modes:
- Smart Dehumidification: Automatically adjusts operation based on desired humidity.
- Jet Dehumidification: Provides quick moisture removal.
- Silent Dehumidification: Operates quietly for minimal disturbance.
- Spot Dehumidification: Designed for targeted drying, such as shoes, using an extension hose.
- Laundry Dehumidification: Continuously dries laundry.
- Humidity Control: Allows users to set the desired humidity level between 30% and 70% in 5% increments.
- Fan Speed: Adjustable fan speed (High, Low) to control the rate of dehumidification.
- Timer Function: An Off Timer can be set for up to 8 hours, allowing the device to turn off automatically.
- UVnano Function: Uses UVnano LED to reduce bacteria in the air. This function can be turned on/off via the control panel.
- Ionizer Function: Removes harmful bacteria from the air.
- Bucket Full Indicator: A light illuminates and an audible warning sounds when the water tank is full, indicating it needs to be emptied.
- Continuous Drainage: The device can be set up for continuous drainage using a commercial hose (16mm internal diameter) to avoid frequent emptying of the water tank.
- LG ThinQ Application: The dehumidifier can be controlled and monitored remotely using the LG ThinQ app on a smartphone. This includes setting operation modes, humidity levels, and checking the device status. The app also supports Smart Diagnosis for troubleshooting.
- Smart Diagnosis: Allows users to diagnose potential issues with the appliance by using the LG ThinQ app or by listening to sounds emitted by the device and comparing them to information in the manual.
Maintenance Features
Regular maintenance is crucial for the optimal performance and longevity of the dehumidifier:
- Cleaning the Exterior: The exterior can be cleaned by removing dust with a vacuum cleaner and wiping with a soft cloth. Avoid using harsh chemicals like sulphuric acid, hydrochloric acid, or organic solvents.
- Cleaning the Water Tank: The water tank should be regularly cleaned. To do this, press the fixing part on both sides of the water tank to take out the lid, then wipe the inside of the tank. Do not open the lid because there is a float to detect full water inside.
- Cleaning the Filters: The Pre-Filter should be pushed to the left to remove it, then cleaned with a vacuum cleaner or soft brush. If contamination is severe, wash with water using neutral detergent (not hotter than 40°C). The cleaning period for the Pre-Filter is 1 month. After washing, completely dry it in shade.
- Storage: When storing the appliance for a long period, ensure it is in a dry and shaded place. Package the appliance to prevent dust or foreign substances from entering. Do not store in humid or direct sunlight.
- Defrost Operation: If frost forms on the heat exchanger due to low indoor temperature, the device automatically removes the frost.
- Troubleshooting: The manual provides a detailed troubleshooting guide for common issues, including the appliance not operating, little dehumidification, humidity not decreasing, and connectivity problems with LG ThinQ. It also describes normal operating sounds of the product (wind, buzzing/grinding, high frequency, and clack sounds).
Safety Instructions
The manual emphasizes several safety precautions:
- General Safety: Read and save all instructions. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
- Installation Safety: Do not install on an uneven or inclined surface, in an area exposed to direct sunlight or near heat-generating equipment. Do not install in a place where combustible gas may leak or industrial oil or metallic particulates are present. Ensure the power cord is not bent, excessively pulled, or placed under rugs/carpeting.
- Operation Safety: Do not immerse the appliance in water. Avoid gas leakage (isobutane, propane, LNG, etc.) and abnormal noise, odor, or smoke. Do not clean with brushes, cloths, or sponges which are abrasive or made of metal. Do not use or store fire, combustibles (ether, benzene, alcohol, drugs, propane, butane, combustible spray, insecticide, air freshener, cosmetics, etc.) or flammable materials near the product. Do not allow animals or pets to chew on the power cord. Do not move the appliance when it is in operation. Do not hit the appliance. Do not insert hands or metal objects into the air inlet or outlet.

Do not place combustion appliances directly in the path of the dehumidifier’s airway. Do not use the product in places where it could be splashed by water or in direct sunlight or rain.
- UVnano LED Safety: Do not disconnect or replace the UVnano LED arbitrarily. LEDs must be replaced only by LG-approved service providers. Harmful UVnano radiation may leak if the device is used in an unintended way or if the wires are damaged. UVnano radiation, even in very small amounts, can harm the eyes and skin. Do not stare at the light source. Do not operate UVnano LED outside of the appliance. Read the maintenance instructions before opening the appliance. The appliance must be disconnected from the supply before replacing the UV-C emitter.
