Q: How do I operate the unit using the remote control?
Ans: Set the temperature, change the fan speed, turn on extra features like Sleep Mode or Turbo Cooling, and choose between the following modes with the remote control: Cool, Heat, Dry, Fan, and Auto. For a breakdown of button functionality, consult the handbook.
Q: How do I clean the air filters?
Ans: Lift the indoor unit’s front panel after turning it off. Rinse with lukewarm water after removing the air filters. Before putting them back in, let them dry completely. For best results, cleaning should be done every two to four weeks.
