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”.

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 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.

• 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.

reusing the Chassis Locking

Bracket and screw.

10.3.6. Attach the Front Grille to the

Cabinet and fasten it with screws.

• Note: Depending upon the location of the AC outlet, route

the AC cord to either the left or right side while installing the

Front Grille.

10.3. Installation Procedures.

CW-C172KR / CW-C202KR / CW-A172KR

10.3.7. Insert the Air Filter.

10.4.1. Remove the Front Intake Grille.

• Raise the Front Intake Grille by approximately 90°. Slide it

to the left to unhinge then pull outwards.

• Lift the air filter by the holder and pull outwards.

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.

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

CW-C172KR / CW-C202KR / CW-A172KR

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.
