CAUTION CAUTION FOR MENDING THE COVER
• In case the cover for penetrating piping is cut off and used
as wiring penetrating hole, after the wiring connection is
finished, mend the cover.
• Cut the sealing material (Small) (9) into two pieces and
wrap each wiring with each piece.
• Seal the clearance around the wiring with putty and insu-
lating material (field supply).
(If insects and small animals get into the indoor unit, short
circuiting may occur inside the control box.)
• If the low voltage wiring (remote controller wiring, trans-
mission wiring) and the high voltage wiring (power supply
wiring, earth wiring) are brought into the indoor unit from
the same place, they may be affected by electric noise
(outside noise) and cause malfunction or failure.
• Keep the distance of 50mm between the low voltage wir-
ing (remote controller wiring, transmission wiring) and the
high voltage wiring (power supply wiring, earth wiring) at
anywhere outside the indoor unit.
If both the wiring are laid down together, they may be
affected by electric noise (outside noise) and cause mal-
function or failure.
Seal with putty and insulating
material.

earth wiring
WARNING
• When wiring, form the wiring orderly so that the control box
lid can be securely fastened.
If the control box lid is not in place, the wiring may float up
or be sandwiched by the box and the lid and cause electric
shocks or a fire.
