the customer read them.
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 resin parts.
If the temperature and humidity in the ceiling is likely to
exceed 30°C, RH80%, use the optional kit for coping with
high temperature and humidity, or additionally stick the
insulation 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.
The direction of air discharge for this product can be
selected. Sealing material of air discharge outlet is
available option for 4-way with sealed corners, and 3-way.
(1) Select the installation location that meets the following
conditions and get approval of the cus tomer.
•
Where the cool and warm air spreads evenly in the
room.
•
Where there is no obstacles in the air passage.
•
Where drainage can be ensured.
•
Where the ceiling 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.
(Refer to Fig. 1)
•
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.
