• Multiple number of indoor units are connected to one outdoor
unit. Name each indoor unit as A-unit, B-unit ….. and the like.
When these indoor units are wired to the outdoor unit and the
BS unit, always wire the indoor unit to the terminal indicated
with the same symbol on the terminal block. If the wiring and
the piping are connected to the different indoor units and
operated, it will result in malfunction.
• Make sure to earth the air conditioner.
Earthing resistance should be according to applicable legislation.
• Do not connect the earth wiring to gas or water pipings, light-
ning conductor or telephone earth wiring.
• Gas piping ........... Ignition or explosion may occur if the
gas leaks.
• Water piping.......... Hard vinyl tubes are not effective earths.
• Lightning conductor or telephone earth wiring ...............
Electric potential may rise abnormally if struck by a light-
ning bolt.
• For electric wiring work, refer to also the "WIRING DIA-
GRAM" attached to the control box lid.
• Carry out wiring between the outdoor units, indoor units and
the remote controllers according to the wiring diagram.
• Carry out installation and wiring of the remote controller accord-
ing to the "installation manual" attached to the remote controller.
• Do not touch the Printed Circuit Board assembly. It may
cause malfunction.
