9.1.2. How to Operate.
(1) Open the Control Panel Cover.
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 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.
Fig. 3
(4) Thermostat Control Knob
Turn the Thermostat Control Knob as shown in Fig. 4.
Usually “6” ~ “7” is the recommended setting position.
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 HIGH 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”.

•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 mm2or 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.

• 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.

10.5. 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.
