3. SELECTION OF INSTALLATION LOCATION!
Points of the operation explanation
In addition to the general usage, since the items in the
operation manual with the
WARNING and
CAUTION marks are likely to result in human bodily
injuries and property damages, it is neces sary not only
to explain these items to the customer but also to have
the customer read them.
Furthermore, it is necessary to have the customer read
through the troubleshooting items while explaining the
above items.
3. SELECTION OF INSTALLATION

If the temperature and humidity in the ceiling is likely to
exceed 30°C, RH80%, use the additional insulation stick
to the indoor unit.
Use the insulation such as glass wool or polyethylene
that has thickness of 10 mm or more. However, keep the
insulated outside dimension smaller than the ceiling
opening so that the unit may go through the opening at
installation.
(1) Select the installation location that meets the follow-
ing conditions and get approval of the cus tomer.
