3. If the water tank is dirty, rinse it with clean water. Avoid using detergents, steel balls,
chemical dust removers, diesel oil, benzene, diluents or other solvents. Otherwise, the water
tank will be damaged and leak
4. Replace the empty tank back into the unit. Otherwise, the water full indicator may
remain red and the machine cannot restart.
CONTINUOUS DRAINING
For continuous operation or unattended dehumidification, please connect the attached drain
hose to the unit. Condensate water can then automatically flow into a bucket.
1.Straighten the drainage pipe to prevent kinks or severe bends
2.Insert one end of the drain into the drain into the cistern hole and connect the other end
to the bathroom, outdoor or bucket like container, or the prescribed drainage area.
Warning
1. Please do not block the drain or drain pipe, if the drain pipe is blocked the water will flow
back into the water tank.
2. Please do not bend the drain pipe. The height of the drain pipe should be lower than the
outlet so gravity can allow the correct flow of water.
3. The drain pipe shall be securely connected to the outlet.
