Ventilation hole
Two ventilation holes with a fan are located on both
sides of the front panel. The holes are covered with a
grill and a cover. When the grills become dusty, the fans
do not work properly and the HIGH TEMP indicator
starts to light frequently. In this case, remove the
ventilation hole cover and clean the grill. Unplug the AC
power cord before cleaning the grill.
Caution
Do not touch the interior of the unit when you remove the
grill.
