CAUTION
࡛ For information about the power cable
specifications for indoor and outdoor units, refer to
the installation manual.
࡛ After peeling off cable wires from the pre-installed
tube, insert a contraction tube.
3 Insert both sides of core wire of the power cable into
the connection sleeve.
࡛ Method 1: Push the core wire into the sleeve from
both sides.
࡛ Method 2: Twist the wire cores together and push it
into the sleeve.

CAUTION
࡛ If cable wires are connected without using connecting
sleeves, their contact area becomes reduced, or
corrosion develops on the outer surfaces of the wires
(copper wires) over a long time. This may cause an
increase of resistance (reduction of passing current)
and consequently may result in a fire.
4 Using a crimping tool, compress the two points and
flip it over and compress another two points in the
same location.
࡛ The compression dimension should be 8.0.
࡛ After compressing it, pull both sides of the wire to
make sure it is firmly pressed.
Compress it 4 times.
