Regulations on wiring diameter differ from locality to
locality. For field wiring requirements, please refer to
your local electrical codes. Carefully observe these
regulations when carrying out the installation.
Table 2 lists recommended wire lengths and cross
section area for power supply systems.
Refer to the WIRING SYSTEM DIAGRAM for the
meaning of "A" and "B" in Table 2.
●
Be sure to comply with
local codes on running the
wire from the indoor unit to
the outdoor unit (size of
wire and wiring method,
etc.).
●
Each wire must be firmly
connected.
●
No wire should be allowed
to touch refrigerant tubing,
the compressor, or any
moving part.
To avoid the risk of electric
shock, each air conditioner
unit must be grounded.
●
Be sure to connect the
power supply line to the
outdoor unit as shown in
the wiring diagram. The
indoor unit draws its power
from the outdoor unit.
