Maintenance – Water Drainage

This portable air conditioner is designed to exhaust most or all water dehumidified from the air. In high humidity situations, the internal water reservoir may fill. If the reservoir is full, both the compressor and motor will stop and the unit will buzz a warning (you can press any button to stop the buzzing). The “Water” indicator will flash to show you that the reservoir is full. The unit will not operate until you drain the water.

Please empty the water in one of the following ways:

1.	Turn off the air conditioner (avoid
	moving it when full).
2.	Position a container (a water tray, for
	example) underneath the drain hole.
3.	Remove the drain cap & rubber plug
	from the drain hole and allow the water
	to drain out.
4.	When the container is almost full,
	replace the rubber plug in the drain
	hole and empty the water tray.
5.	Repeat steps 2 through 4 until the unit
	is emptied.
6.	Replace the rubber plug and tighten the
	drain cap firmly.
7.	Switch on the unit – the Water Full
	indicator will stop flashing and the unit
		Drain hole
	will resume operation.
