3. SELECTION OF INSTALLATION LOCA-
TION
When unpacking and moving the indoor unit after
unpacked, do not apply force to the piping (refrigerant and
drain) and resin parts.
(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 is no obstacles in the air passage.
• Where drainage can be ensured.
• Where the ceiling lower surface is not 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 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.
• If there is extra space required for * part, servicing can be
conducted more easily if 200mm or more is secured.

Have you carried out field setting? (if necessary)
Are the control box lid, the air filter and the suction grille
attached?
Does the cool air discharge during the cooling operation and
the warm air discharge during heating operation?
Have you explained how to operate the air conditioner
showing the operation manual to the customer?
Have you explained the description of cooling, heating,
program dry and automatic (cooling/heating) given in
the operation manual to the customer?
If you set the fan speed at thermostat OFF, did you
explain the set fan speed to the customer?
Have you handed the operation manual and the instal-
lation manual to the customer?
In addition to the general usage, since the items in the
operation manual with the WARNING and CAU-
TION 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.
It is also necessary to explain the items of “NOT MAL-
FUNCTION OF THE AIR CONDITIONER” to the customer
and have the customer read them carefully.
