Place the outlet of hose over a
drain or bucket and ensure that
water could freely flow out of the
unit.
Do not submerge the end of hose
into water; otherwise it can cause
"Air Lock" in the hose.
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.

5. CLEANING AND CARE
5.1. 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.
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. Set aside
and allow the filter to air dry completely before reinstalling.
Pic1. Switch off the unit and remove
the two air filters.
Pic2. Rinse the air filter under
running water.
Do not touch the evaporator surface with bare-hand, or
could cause injury of your fingers.

5.2. CLEANING UP OF REFRIGERANT
General Measures:
1. Gas/vapor heavier than air. May accumulate in confined spaces,
particularly at or below ground level.
2. Eliminate every possible source of ignition.
3. Use appropriate personal protection equipment (PPE).
4. Evacuate unnecessary personnel, isolate, and ventilate area.
5. Do not get in eyes, on skin, or on clothing. Do not breathe vapors or
gas.
6. Prevent entry to sewers and public waters.
7. Stop the source of the release, if safe to do so. Consider the use of
water spray to disperse vapors.
8. Isolate the area until gas has dispersed. Ventilate and gas test area
before entering. Contact competent authorities after a spill.

period of time (more than a few weeks) it is best to clean the unit
and dry it out completely. Please store the unit per the following
steps:
7.2. DISPOSAL
WARNING!!!
Releasing refrigerant into atmosphere is strictly
forbidden!
Do not dispose of electrical appliances as
unsorted municipal waste, use separate
collection facilities. Contact your local
government for information regarding the
collection systems available. If electrical
appliances are disposed of in landfills or
dumps, hazardous substances can leak into
the groundwater and get into the food chain,
damaging your health and well-being.
1.
Unplug the unit and
remove exhaust hose and window kit store with the
unit.
2. Drain the remaining water from the unit.
3.
Clean the filter and let the filter dry completely in a shaded area.
4. Collect the power cord at the water tank.
5.
Re-install the filter at its position.
6.
The unit must be kept in upright position when in storage.
7.
Preserving the machine in ventilating, dry, non- corrosive gas and safe
place indoor.
ATTENTION:
The evaporator inside the machine has to be dried out before the unit is
packed to avoid component damage and molds. Unplug the unit and place
it in a dry open area for days to dry it out. Another way to dry the unit is
to set the humidity point more than 5% higher than the ambient humidity
to force the fan to dry the evaporator for a couple of hours.
