CAUTION
• When removing the outer sheath of the power supply cable, be
careful not to scratch the inner sheath of the cable.
• Make sure that more than 20mm of the outer sheath of the
indoor unit power and communication cable are inside the
electrical component box.
• Install the communication cable separately from power cable
and other communication cables.
• There is a risk of electric shock when power is applied. Close
the cover of the control box before proceeding to work.
• To inspect the compressor or PBA, first make sure to turn off
the system. Electricity may flow even in a compressor that has
not been used recently. Exercise caution to protect yourself
from an electric shock.

CAUTION
• Do not let the power cable come into contact with the pipes
inside the outdoor unit. If the power supply cable touches
the pipes, the vibration of the compressor is transferred to
the pipes and can damage the power supply cables or pipes,
creating the danger of fire or explosion.
• Make sure that the place where the sheath of power supply
cable is removed is inside the power supply box. If it is
impossible, you should connect the protection tube for power
cable to the power supply box.
• After arranging the power cable into the power supply box,
tighten the cover.
