3. CHOOSING AN INSTALLATION SITE
Hold the hangers at 4 locations to move the indoor unit
when unpacking or after unpacked, and do not apply force
to the piping (refrigerant and drain) and air outlet flange.
If the temperature and humidity in the ceiling is likely to
exceed 86°F (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 3/8 inch (10mm) 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 following
conditions and get approval of the user.
• Where the cool and warm air spreads evenly in the room.
• Where there are no obstacles in the air passage.
• Where drainage can be ensured.
• Where the ceiling's lower surface is not remarkably inclined.
• Where there is sufficient strength to withstand the mass
of the indoor unit. (If the strength is insufficient, the
indoor unit may vibrate and get in contact with the ceiling
and generate unpleasant chattering noise.)
• Where a space sufficient for installation and service can
be ensured. (Refer to Fig. 1 and Fig. 2)
• Where the piping length between the indoor and the
outdoor units is ensured within the allowable length.
(Refer to the installation manual attached to the outdoor unit.)
• Where there is no risk of flammable gas leak.
