Set timer
Set the TIMER to the desired operating time (1 to 8 hours). When the set time has been reached, the machine will shut off automatically.
Regulating air flow direction
Turn the roller on the air vent to control the air flow direction of the vertical louvers.
Move the air vent directly to adjust the air flow direction of the horizontal louvers.
NOTE: 1. To lengthen the compressor's life, when the unit is turned off wait at least 3 minutes before turning it back on.
2. The cooling system will turn off if the ambient temperature is lower than the set one. The ventilation, however,
keeps workingon the set level. If the ambient temperature rises above the selected level, the cooling function will resume.
3. On the contrary, the heat will turn off if the ambient temperature is higher than the set one (still, the ventilation
keeps working on the set level). As the ambient temperature drops below the selected level, the heating function will resume.
4. This machine is equipped with an ANTI-FROST function. While using the heating function in low temperatures,
sometimes the heat will stop for a while in order to melt the frost. As this occurs, just wait for the heating function to resume.
