WARNING
•
•
•
•
•
Be sure to comply with local regulations/
codes when running the wire from the
outdoor unit to the indoor unit.
(Size of wire and wiring method etc.)
A lack of electrical capacitance or incorrect
wiring may cause an electric shock or a
fi
re.
To make sure that the wiring connection
are
secure, use designated cables.
Fix the cables securely so that no external
force applied to the cables may effect the
terminals.
If wiring connections are incomplete or
cables are not
fixed securely, it may cause
a fire.
• Be sure to ground the outdoor unit.
• Incomplete grounding may lead to an
electric shock.
CAUTION
•
•
•
Use a circuit breaker of a type that is
not
tripped by shock waves.
Incorrect/incomplete wiring will cause
