4. Setup
Follow these steps to set up your dehumidifier for first use:
- Unpack: Carefully remove the dehumidifier from its packaging. Retain all packaging materials for future transport or storage.
- Placement: Choose a suitable location. Place the unit on a firm, level surface. Ensure there is at least 20 cm (approximately 8 inches) of clear space around the air inlet (rear) and air outlet (top) for optimal performance. Avoid placing it near heat sources or in direct sunlight.
- Power Connection: Plug the power cord into a grounded electrical outlet (230V).
- Water Tank: Ensure the water tank is correctly inserted into the unit.
5. Operation
5.1 Turning On/Off
- To turn on the dehumidifier, press the ON/OFF button. The digital display will illuminate, and the unit will begin operating.
- To turn off the dehumidifier, press the ON/OFF button again.
5.2 Dehumidification Process
The dehumidifier uses Peltier technology to condense moisture from the air. Humid air is drawn into the unit, passes over a cold surface, and the moisture condenses into water droplets that collect in the water tank. Drier air is then released back into the room.

5.3 Water Tank Management
The dehumidifier is equipped with a 700 ml water tank. When the tank is full, the unit will automatically shut off, and the "Full" indicator on the display will light up.
- Removing the Tank: Gently pull out the water tank from the back of the unit.
- Emptying: Carefully empty the collected water into a sink or drain.
- Reinserting: Slide the empty water tank back into its position until it clicks securely. The unit will resume operation automatically if it was on before.

Figure 5.2: The water tank can be easily removed for emptying.
5.4 Automatic Defrost Function
The DH-2200 features an automatic defrost function, allowing it to operate effectively in lower temperatures. If ice forms on the internal components, the unit will temporarily stop dehumidifying and enter defrost mode. Once the ice has melted, it will automatically resume normal operation.

Figure 5.3: The automatic defrost function ensures continuous operation even in cooler environments.
5.5 Timer Setting
Use the Time Setting button to program the dehumidifier to turn off after a set period. Refer to the control panel diagram (Figure 3.3) for button location. Specific timer intervals are typically indicated on the display or in the product's full specifications.
5.6 Air Purifying Function
Press the Air Purifying button to activate the air purification mode. This function helps to clean the air by removing particles and odors, complementing the dehumidification process.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your dehumidifier. Always unplug the unit before cleaning.
- Exterior Cleaning: Wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface.
- Water Tank Cleaning: Periodically clean the water tank to prevent mold and bacteria growth. Remove the tank, wash it with mild soap and warm water, rinse thoroughly, and dry before reinserting.
- Air Filter Cleaning (if applicable): While not explicitly detailed in the product features, many dehumidifiers have an air filter. If your model includes one, gently remove it and clean it with a vacuum cleaner or wash it with warm, soapy water. Ensure it is completely dry before reinserting.
- Storage: If storing the unit for an extended period, ensure the water tank is empty and clean. Store in a cool, dry place, preferably in its original packaging.
