WARNING
The following precautions need to be followed strictly, in order to avoid hazardous situations,
which could result in death or serious injury.
Electric shock or fi re may result from inadequate or incorrect installation or wiring
procedures.
► System installation must only be performed by an experienced electrician.
► Arrange installation at the dealer where the system was purchased or use a professio-
nal installer.
► System installation must be performed in strict accordance to the installation procedu-
res described in this document.
Damage to the circuit breakers may result from incorrect electrical wiring, insuffi cient
electrical circuit capacity or use with other electrical devices.
► Always use a dedicated branch circuit for electrical wiring.
► Strictly avoid using other electrical devices within the same electrical circuit.
► Make sure the electrical circuit used has suffi cient capacity.
Overheating or fi re may result if connections or attachments are not secure.
► Use the specifi ed cables (type and wiring diameter) for the electrical connections, and
securely connect the cables.
► Run and fasten the cables securely so that external forces or pressure placed on the
cables will not be transmitted to the connection terminals.
Suff ocation can result if refrigerant gas leaks and exceeds the limit density in a small
room.
► Installation of the refrigerant piping must only be performed by an experienced, quali-
fi ed installer to minimize the risk of leaks.
► Install so that even if refrigerant gas leaks into the instalation space, it will not exceed
the practical limit density of 0.44 kg/m
cordance with the local regulations for facility air conditioning equipment. However, for
further limits and calculations to be done, see → 1.4 Instructions for safe handling of
R32
► If the refrigerant gas concentration does exceed the density limit, do one of the
following:
Poisonous gas can result if refrigerant gas comes into contact with fi re.
► After installation of refrigerant pipes, perform a dry nitrogen gas sealing test to check
that there are no leaks.
► Ventilate the work area if refrigerant gas leaks during installation.
► Prevent the refrigerant gas from coming into contact with a fan heater, stove, range, or
