Take adequate measures to prevent the outdoor unit •
from being used as a shelter by small animals. Small
animals making contact with electrical parts can cause
malfunctions, smoke, or fi re. Instruct the customer to
keep the area around the unit clean.
NOTE
Install the power supply and control wires for the indoor •
and outdoor units at least 3.5 feet away from televisions
or radios to prevent image interference or noise. De-
pending on the radio waves, a distance of 3.5 feet may
not be suffi cient to eliminate the noise.
In a domestic environment this product may cause radio •
interference in which case the user may be required to
take adequate measures.
Dismantling the unit, treatment of the refrigerant, oil and •
additional parts must be done in accordance with the
relevant local, state, and national regulations.
Do not use the following tools that are used with con-•
ventional refrigerants: gauge manifold, charge hose,
gas leak detector, reverse fl ow check valve, refrigerant
charge base, vacuum gauge, or refrigerant recovery
equipment.
If the conventional refrigerant and refrigerator oil are •
mixed in R410A, the refrigerant may deteriorate.
This air conditioner or heat pump is an appliance that •
should not be accessible to the general public.
As design pressure is 478 psi, the wall thickness of •
fi eld-installed pipes should be selected in accordance
with the relevant local, state, and national regulations.
BEFORE INSTALLATION2.
WARNING
Entrust installation to the place of purchase or a qualifi ed •
serviceman. Improper installation could lead to leaks and, in

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 reach-

a sling of soft material or protective plates together 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.
PRECAUTIONS2-1
Be sure to instruct customers how to properly operate the •
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.
