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 necessary 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 LOCATION
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 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 following
conditions and get approval of the customer.
• 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 in­
door 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.
• Where the piping length between the indoor and the out­
door 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.
