Operating Instructions
Grille and Case
Turn the air conditioner off and remove the plug
from the wall outlet before cleaning.
To clean, use water and a mild detergent. Do not
use bleach or abrasives.
CAUTION: DO NOT operate the air conditioner without a filter
because dirt and lint will clog it and reduce
performance.
Important
Long-off period maintenance
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
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.
