Total wire length: 500 m or less
(The wire length between indoor units
should be 200 m or less.)
Number of connectable units

Attention
 Use the field supplied RC wiring
with at least 1 mm in thickness of
insulation part including the sheath.
Regulations on wire diameters
differ from locally to locally. For
field wiring rules, please refer to
your LOCAL ELECTRICAL CODES
before beginning. You must ensure
