<<Mending method of wiring penetrating hole>>
• After wiring connection is nished, to prevent the penetra-
tion of water, small animals and insects into the indoor unit
from the outside, mend the respective covers for wiring
penetrating hole for the power supply wiring/ground wiring
and the remote controller wiring/transmission wiring.
• Cut the sealing material (Small) (13) into two pieces and
wrap each wiring with each piece.
• Seal the clearance around the wirings with putty and insu-
lating material (eld supply).
If insects and small animals get into the indoor unit, short
circuiting may occur inside the control box.
• Keep the distance of 1-15/16 in. (50 mm) or more between
low voltage wiring (remote controller wiring, transmission
wiring) and the high voltage wiring (power supply wiring,
ground wiring) at anywhere outside the indoor unit. If both
wirings are laid down together, they may be affected by
outside electrical noise and cause malfunction or failure.
