This unit has a continuous drainage
port. The user can purchase a drain-
age pipe with an inner diameter of 13
~13.5mm (pipe length is about 1.3-1.5
meters) and install it on the drainage
equipment to achieve continuous dra-
inage of condensate. When installing
continuous drainage equipment, be
sure to stop the unit and pull out the
power plug.
NOTES:
To ensure smooth drainage, the height
of the drainage pipe should not be higher
than the drain port. Do not bend or block
it, too.
When the end of the drainage pipe is plac-
ed in the drain port, the middle part of the
pipe must be level to avoid water accumu-
lated in the drainage pipe and keep normal
drainage.
Check the drainage pipe regularly to make
sure that they are still connected proper-
ly and are not damaged or blocked.
If the temperature of water inside the drain-
age pipe is quite different from the ambient
temperature, condensation water will be
generated on the surface of pipe. In this
case, please conduct insulation for the
drainage pipe before operation.
The water bucket cover must be installed
correctly on the water bucket to prevent
the dehumidifying water from flowing into
the room and soaking the furniture.
