Your machine is equipped with two drain plugs on the backside, De-humdifier mode and Air Conditioning
mode. Water will need to be drained only in two conditions :

  • De-humidifier mode
  • Air Conditioning mode, when ambient humidity is very high

Whenever there is excess water accumulation inside the unit, and it needs to be drained. The machine will stop running and will show an error message. This error message indicates that the water needs to be drained out using below given procedures :

Water Drain (Air Conditioning Mode)

  • Your machine is equipped with an Auto-Evaporation System, due to which no water needs to be drained in Air Conditioning Mode.
  • However in high humidity areas, you may need to drain water from
    this drain plug.
  • In order to drain water from this drain plug, please open the cap andplace a water tray under the drain plug.
  • Water will drain out automatically and will be collected in this tray.

Continuous Water Drain (De-humidifier Mode)

  • When the unit is running in de-humidifier mode you have to keep
    emptying the water stored inside the water tank.
  • The unit has a threaded drain connection located on the back side
    (refer to fig.).
  • Remove the drain plug, install the drain connector(5/8″ universal
    female mender) with 3/4″ hose(locally purchased).
  • Once a hose is attached the water drains into the hose. The hose can
    then be directed away from the dehumidifier into a floor drain.
