  Your HELLER Air Conditioner might restart frequently due to several reasons: it may be in direct sunlight (close the curtains); there may be open windows or doors, too many people, or a heat source in the room (close doors and windows, remove the heat source); the filter might be dirty (clean or replace the filter(s)); or the air inlet or outlet could be blocked (remove the blockage).

  If your HELLER Air Conditioner isn't working, it could be due to a few reasons. First, ensure it's properly connected to a power supply and switched on. If 'FL' is flashing on the display, drain the water. Also, if the timer-off function is running, wait three minutes before turning the unit back on.
