OPERATION INSTRUCTIONS 

 

The temperature setting range of this air conditioner is from 61F to 77F. To set the temperature, press the + or – 
buttons. Once the set temperature is achieved, the compressor and the fan will stop 

NOTE: This unit uses heat pump from heating and the heating mode does not work when temperature is below 
45F. 

 

To set the fan speed, press the Fan Speed button. In heating mode, the difference in noise level between the 3 
fan speeds is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should 
be able to hear the difference between high and low fan speed settings. 

 

FAN ONLY MODE 

In this mode, only the fan of the air conditioner runs and circulates the air in the room. To activate this function mode, 
press the MODE button until the FAN indicator light comes on. In this function mode, the temperature cannot be set. 
Subsequently, set the desired fan 

speed by pressing the FAN button. Fan Only mode requires that the exhaust 

hose be removed. 

 

TIMER (DELAYED SWITCH ON / OFF) FUNCTION 

This function mode enables a delayed switch ON or delayed switch OFF of the air conditioner. The time (hours) de-
lay can be set, enabled and disabled. 

 

SETTING SWITCH OFF TIMER 

With the air conditioner operating in any function mode, press the TIMER button. The TIMER OFF light will come on. 
Then set the desired time delay OFF hours by pressing the UP and DOW N buttons. The time increments are at 0.5 
hour to up to 10 hours, followed by 1 hour increment up to 24 hours. When the delay time set has elapsed, the air 
conditioner switches off. To cancel the delayed switch off function, turn off the air conditioner or adjust the time set-
ting to 0.0. 

 

SETTING DELAYED SWITCH ON TIMER 

With the air conditioner is off, press the TIMER button. The TIMER ON light will come on. Then set the desired time 
delay ON hours by pressing the UP and DOW N buttons. The time increments are at 0.5 hour to up to 10 hours, fol-
lowed by 1 hour increment up to 24 hours. When the delay time set has elapsed, the air conditioner switches on.  To 
cancel the delayed switch on function, turn on the air conditioner or adjust the time setting to 0.0. 

 

SLEEP MODE 

In this mode, the air conditioner gradually increases the set temperature in cooling mode, decreases the noise level 
and conserves energy. In Sleep and cooling mode, the set temperature is increased by 1°C/ 2°F in the first 30 
minutes. The temperature will then increase by another 1°C/ 2°F after an additional 30 minutes. This new tempera-
ture will remain the same for 7 hours. To activate this function mode, press the SLEEP 

button until the SLEEP   

indicator light comes on. 

 

AUTO RESTART 

In the event of a power outage, the air conditioner restarts at the previously set function mode and settings when 
power is restored.  

 

CONTROLLING THE AIR FLOW DIRECTION 

The louvers can be controlled to Auto-Swing or in a fixed direction. To control the air flow direction by Auto-Swing, 
press the SWING button.  To set the louvers in a fixed angle or direction, press SWING button while on Auto-Swing 
mode when desired angle is chosen.
