How to Operate.
(1) Open the Control Panel Cover.
Air Swing Switch
Thermostat
control knob
Main Control
knob
Fig. 1
(2) Power Supply
Switch off the breaker and set the Main Control Knob to the
OFF position before connecting the power plug cord to an
independent power supply.
Fig. 2
(3) Main Control Knob
Set the Main Control Knob to either LOW COOLING or
HIGH COOLING and LOW HEATING or HIGH HEATING
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 or heating
operation setting, WAIT at least 3 minutes before
resetting to cooling or heating operation.
Fig. 3
(4) Thermostat Control Knob
Turn the Thermostat Control Knob as shown in Fig. 4.
Usually “6” ~ “7” is the recommended setting position for
cooling and “4” ~ “5” for heating.
Note: When the Thermostat Control Knob is set to “10”,
moisture may freeze onto the evaporator fins and prevent
effective cooling. If this happens, turn the Main Control
Knob to FAN, and the Thermostat Control Knob
counterclockwise. This will quickly defrost the evaporator
fins so that normal cooling can be resumed.
Fig.4
(5) Air Swing Switch
(Airflow direction adjustment side-to-side)
To obtain a fixed 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 circulation, set the Air Swing
Switch to “ON”.

10 How to Install
10.1. Before installing the air conditioner, please read the following:
10.1.1.
Electrical Work.
• Always use at the rated voltage and with a specific air conditioning circuit.
• Power supply point shall be the place where there is ease for the power disconnection in case of emergency.
• Some installation locations may require installation of a short-circuit breaker.
• Time delay fuse or circuit breaker rating is 16 Ampere for CW-C172KR/CW-A172KR/CW-C202KR/CW-A202KR.
• Nominal cross sectional area of power supply wire must be 3 core x 2.5 mm2 or above.
• The power supply must be from an independent circuit.
• All electrical installations must be made in accordance with local wiring and safety regulations wherever applicable.
• There must be a double pole switch with minimum of 3 mm contact gap in the fixed installation circuit.
10.1.2.
Select the Best Location.
• Install the unit at the nearest power outlet.
• The air conditioner should be installed in a dry place where there are no draughts.
• Condensation from the air conditioner must be drained into an appropriate location.
• Do not install in a location where flammable gas leaks is a possibility.
• Usage in locations where the air is salty such as coastal areas or near hot spas, or where sulphurous gas is generated, may
lead to a malfunction.
• Do not install this appliance in a laundry room or other locations where water may drip from the ceiling, etc.
• Select an installation location which is rigid and strong enough to support or hold the unit and select a location for easy
maintenance.
10.2. Preparation for Installation.
• There should not be any obstacles surrounding the unit.
• Prepare an installation hole that is only slightly bigger than the cabinet size.

10.3.7.
Insert the Air Filter.
10.3.8.
Attach the Front Intake Grille.
• Slide the Front Intake Grille slightly to the right to attach it,
then push down to secure it.

10.4.3.
Remove the Front Grille.
• Raise the Front Intake Grille by approximately 90°. Slide it
to the left to unhinge then pull outwards.
1. Open the Control Panel cover.
When performing the following steps, do not pull the bottom
edge of the Front Grille towards you more than 3 inches or
you may damage the top tabs.
2. Press inward on the Cabinet near the bottom right side of
the Front Grille while pulling the Front Grille to the right then
slightly towards you to release the right tab.
3. Press inward on the Cabinet near the bottom left side of the
Front Grille while pulling the Front Grille to the left then
slightly towards you to release the left tab.

10.5. Condensed Water Drainage.
This air conditioner employs a “Slinger-Up System” which is
designed to splash the condensed water on the condenser coil
for maximum cooling efficiency, thus producing a splashing
sound. If the splashing sound annoys you, you can provide an
outside drainage by using the following procedure which may,
however, cause a small loss of performance.
Note: If the unit is installed at coastal area, drainage of
condensed water is recommended to prevent the condenser
being corroded easily.
1. Slide the Chassis out from the Cabinet.
2. Remove the rubber plug from the Base Pan (If any).
3. Install the Drain Pan at the right corner of the Cabinet
with 2 screws.
4. Connect the drain hose to the outlet of Drain Pan bottom.
5. Slide the Chassis back into the Cabinet.
Note: Drain hose or tubing can be purchased locally to satisfy
your particular needs.
