WARNING
When connecting the power supply cable and trans-
mission cable, layout the wiring so that the cover of
this unit is securely fixed. If the cover is imperfectly
fixed, it may cause fire or overheating of the terminals.
Perform earth (ground) work positively. Do not connect
the earth (ground) cable to a telephone earth (ground)
cable, water pipe, or conductor rod. It will cause
trouble or fire.
Always fasten the outside covering of the cable with
binder. If the insulator is chafed by friction, electric
leakage may occur.
If any cable is damaged, do not repair or modify it
yourself. Improper work will cause electric shock or
fire.
CAUTION
Do not bind up the power supply cable together with
the transmission cable or remote controller cable. It
will cause erroneous operation.
When performing wiring work, be careful not to dam-
age the cable or injure yourself. Also, connect the con-
nectors securely. loose connectors will cause trouble,
heating, fire, or electric shock.
Install the indoor and outdoor units, power supply
cable, transmission cable and remote controller cable
1m (40 in.) away from television and radio to avoid
distorted images and noise. Otherwise, a malfunction
could result.
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, electric shock, or fire.
Confirm 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
damage the electric parts and cause smoke and fire.
When installing the connection cables near a source
of electromagnetic waves, use shielded cable.
Otherwise,a breakdown or malfunction could result.
▪
When wiring between the outdoor unit, indoor unit, and
Central remote controller, refer to the indoor unit and
outdoor unit installation manuals.
▪
Always connect both ends of the earth (ground) con-
nection of the transmission cable.
▪
Install the disconnect switch to the easily accessible
location.
