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”.

10.5. 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.
