Be sure to comply with
local codes while run-
ning the wire from the
indoor unit to the out-
door unit (size of wire
and wiring method,
etc.).
Every wire must be
connected firmly.
No wire should be
allowed to touch refrig-
erant tubing, the com-
pressor 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.
