2As shown in the figure, peel off the shields from the rubber and wire of the power cable.
•Peel off 20 mm of cable shields from the pre- installed tube.
CAUTION
•For information about the power cable specifications for indoor and outdoor units, refer to the installation manual.
•After peeling off the tube wire, you must insert a contraction tube.
4Using 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.
Compression dimension
•After compressing it, pull both sides of the wire to make sure it is firmly pressed.
