SELECTING INSTALLATION SITE

〈Hold the hanging brackets in the case of moving the
indoor and outdoor units at the time of and after opening
the packages. Do not impose undue force on other parts,
such as the refrigerant piping, drain piping, or flanges, in
particular.〉
〈Add heat insulation material to the indoor unit if the tem-
perature above the ceiling is likely to exceed 86°F and a rel-
ative humidity of 80%.〉
〈Make sure that the insulation material is made of glass wool
or polyethylene foam, has a minimum thickness of 3/8 in.,
and can be accommodated in the opening on the ceiling.〉
(1) Select an installation site where the following conditions are
fulfilled and that meets with your customer's approval.
• A place where cool (warm) air is delivered to the entire
room.
• Where nothing blocks the air passage.
• Where condensate can be properly drained.
• If supporting structural members are not strong enough
to take the unit's weight, the unit could fall out of place
and cause serious injury.
• Where the false ceiling is not noticeably on an incline.
• Where there is no risk of flammable gas leakage.
• Where sufficient clearance for maintenance and service
can be ensured. (Refer to Fig. 2-1)
• Where piping between indoor and outdoor units is possi-
ble within the allowable limit. (Refer to the installation
manual of the outdoor unit.)
