Do not use an extension cord.
Do not start/stop operation by plugging/unplugging the power cord.
If the cord/plug is damaged, replace it with only an authorized replacement
part.
Usage
1. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets , or plants to direct
airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, v entilate the room when used
together with stoves or other heating devices.
3. Do not use this air conditioner f or non-specified special pur poses (e.g.
preserving precision devices, food, pets , plants , and ar t objects). Such usage
could damage the items.
4. Remove the power plug if not using the unit for a long time.
Cleaning and Maintenance
1. Do not touch the metal parts of the unit when removingthe filter. InjurIes can
occur when handling shar p metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can

The air filter behind the front grille should be checked and cleaned
at least once every 2 weeks or more often if necessary.
The grille is designed to clean the filter downward.
To remove:
1 Open the inlet grille upward by pulling out the bottom of the
inlet grille. (Refer Fig. 1)
(Fig. 1)
(Fig. 2)
2 Using the tab, pull up slightly on the filter to release it and pull

3 Clean the filter with warm, soapy water below 40°C (104°/F).
4 Rinse and gently shake the water from the filter and let it dry
before replacing it.
CAUTION: DO NOT operate the air conditioner without a filter
because dirt and lint will clog it and reduce
performance.
Drainage
1 In humid weather, excess water may cause the BASE PAN to overflow.
To drain the water, remove the DRAIN CAP
2 To remove the condensed water, you can install the drain pan as below.
1. Take the drain pan which is located in the air discharge.
2. Install the drain pan to the right corner of the cabinet with 4 screws.
3. Connect the drain hose to the outlet located at the bottom of the drain

Long-off period maintenance
(Optional)
1)If the air conditioner is not going to be used for a long period, run the Air-conditioner with the
setting in FAN Mode only and the fan speed on "HIGH" for about half an hour, to dry the whole
Air-conditioner.
2)After a long off period when you are going to use the air conditioner again, repeat above point
no. 1.
Caution
There will possibly be foul smell when the machine is started after a long time (1 week). This is due
to various odours emitted by smoke, foodstuff, cosmetics and others, which syicks to the Air Filter
and Evaporator coil. Hence, clean the Air Filter and the Evaporator before you start the machine
after long time to avoid foul smell.

Installation Instructions
Select the Best Location
A
To prevent vibration and noise, make sure the unit is installed securely and firmly.
B
C
Install the unit where the sunlight does not shine directly on the unit.
D
There should be no obstacle, such as a fence or wall, within 50cm from the back of the cabinet because it will prevent
heat radiation of the condenser.
Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.
Install the unit a little obliquely outward not to leak the condensed water into the room (about 10 ~ 15mm or 1/4
bubble with level).
CAUTION: All side louvers of the cabinet must remain exposed to the outside of the structure.
