1. BEFORE YOU BEGIN
Please read the operating instructions carefully before using your dehumidifier for
the first time.
1.1 PRODUCT DESCRIPTION
The dehumidifier is used to remove excessive moisture from the air. The resulting reduction in
relative humidity protects buildings and their contents from the adverse effects of excess
humidity.
2. FOR YOUR SAFETY
Your safety is the most important thing we concerned!
Please read this manual carefully and fully understand before operating your
dehumidifier.

6.MAINTENANCE
Note: before cleaning and maintaining the machine, please be sure to turn off the machine
and unplug the power to avoid electric shock.
CLEANING THE AIR FILTER (every two weeks)
Dust collects on the filter and restricts the airflow. The restricted airflow reduces the
efficiency of the system and if it becomes blocked it can cause damage to the unit.
The air filter requires regular cleaning. The air filter is removable for easy cleaning. Do not
operate the unit without an air filter, or the evaporator may be contaminated.
Switch off the unit and remove air filter.
Rinse under a running water or using the vacuum to
clean the dust.
