Selection of installation place
In case of continued operation of the indoor unit under high-humidity conditions as described below, dew
may condense and water may drop.
Especially, high-humidity atmosphere (dew point temperature : 23°C or more) may generate dew inside
the ceiling.
1. Unit is installed inside the ceiling with slated roof.
2. Unit is installed at a location using inside of the ceiling as fresh air take-in path.
3. Kitchen
Advice
• Set a service check opening panel at right side of the unit (size: 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 10mm or more thick.)
Ceiling height
SM56, SM80 Type
SM110, SM140, SM160 Type
When the height of the ceiling exceeds the distance of the item Standard/4-way in Table on the next
page, the hot air is difficult to reach the floor.
Therefore, it is necessary to change the setup value of the high ceiling switch or discharge direction.
The high-ceiling setting is also necessary when installing separately sold filters.
