To avoid water spillage:
•
As the negative pressure of condensate drain pan is large, tilt the drain hose downward
toward the floor. It is appropriate that the degree of inclination should exceed 20 degrees.
•
Straighten the hose to avoid a trap existing in the hose.
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.
1. Press POWER button to switch off the unit and unplug the power cord.
2. Remove the filter mesh from the unit.
3. Use a vacuum cleaner to suck dust from the filter.
4. Turn the filter over and rinse the air filter under running water. Let the water run through the
filter in the opposite direction of air flow.
5. Set aside and allow the filter to air dry completely before reinstalling.
