• Set a service check opening panel at right side of the unit (size: 17.7" × 17.7" (450 × 450mm) or more) for piping,
maintenance, and servicing.
• If installing a unit at such place, put insulating material (glass wool, etc.) additionally on all the positions of the
indoor unit which come to contact with high-humidity atmosphere.
REQUIREMENT
When the humidity inside the ceiling seems to be higher than 80%, attach a heat insulator to the side (top)
surface of the indoor unit. (Use a heat insulator that is 0.4" (10 mm) or more thick.)
