● In cooling or drying operation, the condensation water will be drained to the chassis and spattered by water-striking motor. As
the temperature of condenser is high, most of the condensation water will be evaporated and drained to outdoor. So usually, only
a little condensation water will be accumulated inside the chassis and you do not need to discharge the water frequently.

● When the chassis is full with water, the buzzer will give out 8 sounds and "H8" is displayed to remind user to discharge water:

●Move the unit to a suitable place for discharging water; do not tilt the unit and keep it horizontal during moving;

●Take the drainage pipe from the clip and pull out the rubber plug on the drainage pipe to discharge water;

●Put back the rubber plug onto drainage pipe after finishing discharging water and then fix the pipe on the cli
