water in the back drain outlet of the unit you must
dry it. Make sure the hose is secure so there are
no leaks and the end of the hose is level or sloping
downwards to let the water flow.

• Direct the hose toward the drain, making sure that
there are no kinks that will stop the water flowing.

• Select the desired humidity setting and fan speed on
the unit for continuous draining to start.
