Indoor Unit
(1) Power cord 3×4mm² (H07RN-F)
(2) Power cord 3×1.0 mm² (H05VV-F)
(3) Communication cords 2×0.75mm² (H05RN-F)
CAUTION
Take great care when carrying out the following
connections, so as to avoid malfunction of the
air-conditioning unit because of electromagnetic
interference.
The signal line of the wired controller must
(1)
be separated from the power line and the
connecting line between the indoor unit and
the outdoor unit.
In case the unit is installed in a place
(2)
vulnerable by electromagnetic interference,
it is better to use shielded cable or double-
twisted cable as the signal line of the wired
controller.
