4 AIR CONDITIONER INSTALLATION
CHOOSING THE INSTALLATION LOCATION
When installing, use the nearest power outlet. Make sure the power outlet is easy
to reach so you can quickly disconnect your air conditioner in case of emergency.
Ensure that the air conditioner is well supported, securely fastened, easily reachable
and not obstructed.
Aviod location with: salty or sulphurous air, draughts, dampness and flammable gas.
If you install the drainage system, be sure to channel the concensed water to a
suitable location.
Covers, obstructions and unsteady support may cause excessive operating noise and vibration.
The rear end of the air conditioner is splash proof. You don't need to shield or cover it.
R32 refrigerant air conditioner installation and maintenance should be done by competent person.
PREPARATIONS BEFORE INSTALLATION
Dimension
There should not be any obstacles surrounding
the unit.
Prepare and installation hole slightly bigger than the
cabinet size.
Left and right side of the unit should be at least
15 cm away from the wall.
The minimum installation height is 75cm.
(Based on IEC 60335-2-40, there is no restriction for the
minimum installation floor area since the refrigerant charges
is less than 1.224kg.
CAUTION POINT DURING INSTALLATION
When installing air conditioner at glass window
or thin partition, fix the vertical and side supporting
bar to the concrete wall in order to support the weight
of the air-conditioner and reduce the vibration that is
being transferred to the glass window or thin partition.
This can minimize the noise problem caused by
improper installation.
Proposed to use 1/8" x 1-1/4" angle-
aluminium for installation frame and
side supporting bar.

■NOTICE:
When the air conditioner is used at room temperature of 21 degrees or less,
the temperature may be too low, and the air conditioner may be easily
frosted. After frosting, it may be difficult to drain and may flow into the room.
Main Control Knob
Set to LOW COOL or HIGH COOL as desired.
(FAN setting operates the fan only.)
Caution: If the main control knob is turned off or changed to a fan setting
from a cooling operation setting, WAIT at least 3 minutes before
resetting to cooling operation.
Thermostat Control Knob
Set the thermostat control knob to your desired setting. (Usually 6 - 7 is
recommended). If the room temperature is not as desired after a reasonable
period of time, turn the thermostat control knob clockwise to cool the room
more or counter clockwise to cool the room less.
When the thermostat control knob is set to 10, moisture may freeze on
the evaporator fins and prevent effective cooling. If this happens, turn
the Main Control Knob to HIGH FAN and the Thermostat Control Knob
counter-clockwise. This will quickly defrost the evaporator fins to resume
normal cooling operation.
Air Swing Switch
(Airflow direction adjustment Side-to-Side)
To obtain a fix airflow direction, set the air swing switch to "ON" for the
vanes to swing from side to side until the desired flow direction is reached,
then switch it to "OFF".
For continuous side-to-side air cirulation set the air swing switch to "ON".
