The dehumidifier will defrost automatically when freezing occurs. The
dehumidifier will start automatically when defrost process is
complete. Default defrost setting occurs when ambient temperature is
under 18℃
Compressor delay start protection function

start up within 3 minutes of delay protection.
STRUCTURE AND RUNNING
PREPARING BEFORE INSTALLATION
A. Cut off all the electrical to ensure the safety
B. Make sure the power and drain tunnel
C. Prepare necessary tools like screwdriver, thread rod, spanner etc.
START INSTALLATION
A. Drill four fixing holes on the ceiling according to the position of install
hole on the machine, then install the expansion screw to fix the thread rod.
B. Install the machine through the four thread rods, and adjust the height
according the space to ensure the machine on horizontal level.
C. Connect the drain tube to make sure no leakage, no block for the
drainage.
Connect the power, please make sure the power supply is 208~240v/60hz
and have overload protection.

2. Wipe the body with soft cloth in daily use. Use a wet hard cloth to wipe dirty
body, or use a soft cloth moistened with a little diluted neutral detergent.
3. Filter Cleaning: it will affect the dehumidifying effect or cause malfunction if
accumulate dust on filter , it needs to be cleaned regularly, clean it at least once a
month.Use dust catcher to remove dust or put filter into clean water (<40 ℃) to
wash, then place filter back after cleaning.
NOTE: The filter cannot be put in sunlight directly or roasted to avoid distortion.
The filter must be placed before power up machine.
4. Non use of equipment :Cut the power or unplug power line. Place equipment in
