drainage
To treat condensed water will be as follows:
1. Bottom drainage. Connect drain hose to the bottom drain tray. It
will slightly affect cooling performance, but will reduce the noise
caused by spraying the condensed water.
Note: Only optional for models with bottom drain hole. For
pump heating, the bottom drainage must be chose.
Back
drain hole Bottom drain hole

2. Back drainage. Connect drain hose to the back drainage hole. It
will slightly affect cooling performance, but will reduce the noise
caused by spraying the condensed water.
3. Non-drainage. Block the drain hole(s) by rubber plug(s).
The condensed water will be sprayed to condenser, and will im-
prove the cooling performance.
Installation procedure of bottom drainage:
1. Remove the rubber plug from the bottom of cabinet (if installed).
2. Take out the drain tray and screws from accessory.
3. Fix the drain tray onto the bottom of cabinet by screws.
4. Connect an extension drain hose (locally purchased) to the outlet
of drain tray.

ton, along with any inserts placed into the side louvers.
select the best location
1. To avoid vibration and noise, make sure the unit is installed se-
curely and firmly.
2. Install the unit where the sunlight does not shine directly on the
unit. If the unit receives direct sunlight, build an awning to shade
the cabinet.
3. There should be no obstacle, such as a fence or wall, within 50 cm
from the back of the cabinet because it will prevent heat radia-
tion of the condenser.
Restriction of outside air will greatly reduce the cooling and heat-
ing efficiency of the air conditioner.
4. Install the unit a little obliquely downward to outside not to leak
the condensed water into the room (about 3~40 with level).
5. Install the unit with its bottom portion 75~150cm above the floor
