When the dehumidifier is switched ON, a fan pulls moisture-laden air into the dehumidifier where it passes through dehumidifying coils inside the unit. These coils condense moisture from the air and collect it in the water tank. The dry air is then exhausted from the dehumidifier. The air flows through the air vents of the dehumidifier into the room as dry, warm air.

IMPORTANT: The dehumidifier is designed to operate between 41°F (5°C) and 89°F (32°C). The dehumidifier’s performance may be greatly reduced if room temperature is beyond this temperature range.


  • Before using the dehumidifier, place the unit UPRIGHT for at least 1 hour before use to allow the refrigerant to stabilize. If the unit was tilted on its side or upside-down during transportation, set the unit upright for 4 hours before use.
  • For optimal efficiency, the dehumidifier must be operated in an enclosed area. Keep all doors, windows and other outside entrances to the room closed.Honeywell TP-Small 24 Liter Dehumidifier fig2
  • Place the dehumidifier in an area where the temperature will not drop below 41°F (5°C)
  • Place the dehumidifier at least 17.7 inches (45 cm) away from other objects (e.g. curtains or furniture) that may restrict airflow from the back or through the air vents of the unit.
  • The dehumidifier must be positioned on a level floor.Honeywell TP-Small 24 Liter Dehumidifier fig3

IMPORTANT: The effectiveness of the dehumidifier can be influenced by different factors. One factor is the rate at which new, moisture-laden air enters the room and the amount of air circulating in and out of the area to be dehumidified. For example, if a door to a basement is constantly opened, letting new, moisture-laden air into the room, dehumidification will take longer than if the door was kept closed. If the dehumidifier is in a room with a storage closet or cabinets, it will have little or no effect in drying the inside of the storage closet or cabinets unless there is adequate circulation of air in and out of these spaces. To dehumidify these spaces, open the storage door or cabinet doors to allow air circulation. You may find that installing a second dehumidifier may be required for larger enclosed areas.


  • This Dehumidifier is packaged with a colored or transparent tape to secure some parts during transportation. Remove the colored or transparent packaging tape from the unit.
    •  Gently pull the water tank from out of the dehumidifier
    • Remove the splash guard from the top part of the water tank
    • Take out the power plug, drain hose and other accessories, which is placed inside the tank of the dehumidifier.
    • Once all accessories have been removed, replace the splash guard onto the top part of the water tank. Make sure that the tank is properly positioned.
    • There is a Foam Float inside the water tank that senses the water level to automatically stop dehumidification when the water tank is full. Make sure the Foam Float is positioned correctly inside the water tank by ensuring it lies level with the top edge of the water tank.
