What maintenance is required for the outdoor unit?

LG L3UC482FA0 Air Conditioner ·

The heat exchanger coils and panel vents of the outdoor unit should be checked regularly. If clogged with dirt or soot, they may be professionally cleaned with steam, as dirty or clogged coils will reduce operating efficiency and cause higher operating costs. Always contact an authorized service technician for repair or maintenance of the unit. (Page 22)
