BEFORE INSTALLATION
2.
WARNING
Entrust installation to the place of purchase or a qualifi ed
•
serviceman. Improper installation could lead to leaks and, in
worse cases, electric shock or fi re.
Use of unspecifi ed parts could lead to the unit falling, leaks
•
and, in worse cases, electric shock or fi re.
NOTE
Be sure to read this manual before installing the indoor unit.
•
Be sure to mount an air fi lter (part to be procured in the
•
fi eld) in the suction air passage in order to prevent water
leaking, etc.
The accessories needed for installation must be retained
in your custody until the installation work is completed.
Do not discard them.
Decide upon a line of transport.
1.
Leave the unit inside its packaging while moving, until
2.
reaching the installation site. Where unpacking is unavoid-
able, use a sling of soft material or protective plates togeth-
er with a rope when lifting, to avoid damage or scratches to
the unit.
Be sure to check the type of R410A refrigerant to be used
before installing the unit.
(Using an incorrect refrigerant will prevent normal opera-
tion of the unit.)
For the installation of an outdoor unit, refer to the installation
manual attached to the outdoor unit.
PRECAUTIONS

•
unit (operating different functions, and adjusting the tem-
perature) by having them carry out operations themselves
while looking at the operation manual.
Do not install in locations where the air contains high levels of
•
salt such as that near the ocean and where voltage fl uctuates
greatly such as that in factories, or in vehicles or vessels.

SELECTING INSTALLATION SITE
3.
CAUTION
If you think the humidity inside the installation space might
•
exceed 86°F and RH80%, reinforce the insulation on the
unit body.
Use glass wool or polyethylene foam as insulation so that
the thickness is more than 2 in. and fi ts inside the installation
space opening.
Select an installation site where the following conditions
(1)
are fulfi lled and that meets with your customer’s approval.
Where optimum air distribution can be ensured.
•
Where nothing blocks air passage.
•
Where condensate can be properly drained.
•
Where the supports are strong enough to bear the
•
indoor unit weight.
Where the false ceiling is not noticeably on an incline.
•
Where suffi cient clearance for maintenance and service
•
can be ensured.
