• 1N · m = 10 kgf · cm
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 Plate bottom.
