Product Overview

The MalTec DH-20000A Electronic Dehumidifier utilizes condensation technology to remove moisture from the air. Air is drawn into the unit, cooled below its dew point to condense moisture, and then reheated before being released back into the room. This process is highly efficient and economical.

Key Components:

• Compressor: Circulates refrigerant to cool the evaporator coil.
• Fan: Draws air into and out of the unit.
• Evaporator (Cooling Coil): Cools the air, causing moisture to condense.
• Condenser (Heating Coil): Reheats the dry air before it exits.
• Water Tank: Collects condensed water.
• Pre-filter: Filters dust and larger particles from the air.
• Control Panel: Digital display and touch buttons for operation.

Setup

1. Unpacking: Carefully remove the dehumidifier from its packaging. Retain the packaging for future storage or transport.
2. Placement: Place the dehumidifier on a flat, stable surface in the room where dehumidification is needed. Ensure there is at least 20 cm (8 inches) of clear space around all sides of the unit for proper airflow. Do not place it against a wall or furniture that could obstruct air intake or exhaust.
3. Power Connection: Plug the power cord into a suitable grounded electrical outlet (220-240V, 50Hz).
4. Water Drainage Setup (Choose one):
   • Manual Drainage: Ensure the water tank is correctly inserted into the unit. The unit will collect water in the tank, and you will need to empty it manually when full.
   • Continuous Drainage: For continuous operation without manual emptying, connect the provided drainage hose (105cm length) to the continuous drainage port on the back of the unit. Route the hose to a suitable drain or container, ensuring it is sloped downwards to allow gravity drainage.
5. Filter Installation: Ensure the mesh pre-filter is correctly installed in its designated slot.

  • UP/DOWN Arrows: Adjusts desired humidity level (30-80% in 5% increments) or timer settings.
  • TIMER: Sets the operating time from 1 to 24 hours (in 1-hour increments). The unit will turn off automatically after the set time.
  • HUMIDITY: Press to set the desired humidity level. Use UP/DOWN arrows to adjust.
  • MODE: Switches between operating modes: AUTOMATIC, CONTINUOUS DEHUMIDIFICATION/FAN.
  • STAND-BY (Power Button): Turns the unit ON or OFF.

Operating Modes:

• AUTOMATIC Mode: The unit will automatically adjust its operation based on the set humidity level. When the room humidity reaches the set level, the compressor will stop, and the fan will continue to run for a short period before stopping. The unit will restart if the humidity rises by 3% or more above the set level.
• CONTINUOUS DEHUMIDIFICATION/FAN Mode: The unit will operate continuously, regardless of the humidity level, providing maximum dehumidification. The fan will also run continuously.
• SLEEP Mode: Designed for quiet operation, typically used at night. The display lights dim, and the fan operates at a low speed.

Water Tank Management:

When the water tank is full, the "Waterfull" indicator light will illuminate, an audible signal will sound, and the unit will automatically stop operation to prevent overflow. Empty the water tank and reinsert it correctly to resume operation.

Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your dehumidifier.

1. Cleaning the Pre-filter:
   • The mesh pre-filter should be cleaned every two weeks or more frequently depending on usage and air quality.
   • Unplug the dehumidifier from the power outlet.
   • Remove the pre-filter from its slot.
   • Wash the filter with warm, soapy water. Rinse thoroughly and allow it to air dry completely before reinserting.
   • Do not operate the unit without the filter.
2. Cleaning the Water Tank:
   • Empty and clean the water tank regularly to prevent mold and bacterial growth.
   • Wash the tank with warm water and a mild detergent. Rinse thoroughly.
   • Ensure the tank is completely dry before reinserting it into the unit.
3. Cleaning the Exterior:
   • 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.
4. Storage:
   • If storing the unit for an extended period, ensure the water tank is empty and clean.
   • Clean the pre-filter.
   • Store the unit upright in a cool, dry place, preferably in its original packaging.
