Drainage way as follows.
1. 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.
2. 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 clip;
• After full water protection is eliminated and the compressor has been stopped
for 3 minutes, the unit will resume operation.
