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.

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”.

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.

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.
There should not be any obstacles surrounding
the unit.
Prepare and installation hole slightly bigger than the

The appliance shall be stored in a room without continuously operating ignition sources
(for example: open flames, an operating gas appliance or an operating electric heater)
Do not install, remove and reinstall the unit yourself.
Improper installation may cause Leakage, electric shock or fire. Please engage an authorized dealer
or specialist for the installation work.
Do not add or replace refrigerant other than the specified type.
It may cause product damage, burst and injury. If the supply cord is damaged, it must be replaced by
the manufacturer, its service agent or similar qualified persons in order to avoid hazard.
The room air conditioner must be earthed.
Improper grounding could cause electric shock.
Do not install the unit in a place where there are explosive gas leaks.

Otherwise water will leak out.
In cases that require mechanical ventilation, ventilation openings shall be kept clear of obstruction.
Ventilate any enclosed areas when installing or testing the refrigeration system.
Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.
Confirm after installation that no refrigerant gas is leaking. If the gas comes in contact with a burning
stove, gas water heater, electric room heater or other heat source, it can cause the generation of toxic gas.
