Before starting installation work, turn off the power of this unit and the
connection destination. Do not turn on the power again until installation
is completed. Otherwise, it will cause electric shock or ﬁ re.
Use speciﬁ ed cables or accessory cables to connect to this unit.
Do not modify the cables to connect this unit other than those speciﬁ ed,
do not use extension cables, and do not use independent branch wiring.
It may cause electric shock or ﬁ re.
Install the transmission cables securely to the terminal block. Conﬁ rm
that external force is not applied to the cable. Use transmission cables
made of the speciﬁ ed cable. If intermediate connection or insertion ﬁ x-
ing are imperfect, it will cause electric shock, ﬁ re, etc.
When connecting the cables to this unit, route the cables so that the
cover of this unit is securely ﬁ xed. If the cover is imperfectly ﬁ xed, it may
cause ﬁ re or overheating of the terminals.
Perform earth (ground) work positively. Do not connect the earth (ground)
cable to a telephone cable, water pipe, or conductor rod.
Always fasten the outside covering of the cables with the cable clamp. (If
the insulator is chafed, electric leakage may occur.)
Perform all wiring works so that the user does not touch the wiring.
Otherwise, injury or electric shock could result.
If any cable is damaged, do not repair or modify it yourself. Improper
work will cause electric shock or ﬁ re.
Do not bind the remote controller cable and the transmission cable
together with or parallel to the power supply cable of the indoor and
outdoor units. It may cause erroneous operation.
When performing wiring work, be careful not to damage the cable or
injure yourself. Also, connect the connectors securely. Loose connec-
tors will cause trouble, heating, ﬁ re, or electric shock.
Install the indoor and outdoor units, power supply cable, transmission
cable and remote control cable 1 m (40 in.) away from television and ra-
dio to avoid distorted images and noise. Otherwise, a malfunction could
Perform wiring so that water does not enter this unit along the external
wiring. Always install a trap to the wiring or take other countermeasures.
Otherwise it will cause trouble or electric shock or ﬁ re.
Conﬁ rm the name of each unit and name of each terminal block of the
unit and connect the wiring in accordance with the directions given in
the manual so that there is no incorrect wiring. Incorrect wiring will dam-
age the electric parts and cause smoke and ﬁ re.
When installing the connection cables near a source of electromagnetic
waves, use shielded cable.
Otherwise, a breakdown or malfunction could result.
The terminal screws and earth (ground) screws have different shapes.
Be sure to install the screws in the correct locations. If the screws are
installed in the wrong locations, the circuit board could be damaged.
