CAUTION
•
When connecting cables, you can connect the cables to
the electrical part or connect them through the holes
below depending on the spot.
•
Connect the communication cable between the indoor
and outdoor units through a conduit to protect against
external forces, and feed the conduit through the wall
together with refrigerant piping.
•
Remove all burrs at the edge of the knock-out hole
and secure the cable to the outdoor knock-out using
lining and bushing with an electrical insulation such as
rubber and so on.
•
Must keep the cable in a protection tube.
•
Keep distances of 50mm or more between power cable
and communication cable.
•
When the cables are connected through the hole,
remove the knock-out piece.
