General instructions
All field supplied parts and materials and electric works must
conform to local codes.
Use copper wire only.
Follow the "Wiring diagram" attached to the switch box cover to
wire the outdoor unit, indoor units and the remote controller. For
details on hooking up the remote controller, refer to the
"Installation manual of the remote controller".
All wiring must be performed by an authorized electrician.
A circuit breaker capable of shutting down power supply to the
entire system must be installed.
This system consists of multiple indoor units. Mark each indoor
unit as unit A, unit B..., and be sure the terminal board wiring to
the outdoor unit is matching properly. If wiring and piping
between the outdoor unit and an indoor unit are mismatched,
the system may cause a malfunction.
