*1 Connect to the power switch which has a gap of 3 mm or more when open to
interrupt the source power phase. (When the power switch is shut off, it must
interrupt all phases.)
*2 Use wires in conformity with design 60245 IEC 57.

After the leak test, apply insulating mate-
rial tightly so that there is no gap.
When the piping is to be attached to a
wall containing metals (tin plated) or metal
netting, use a chemically treated wooden
piece 20 mm or thicker between the wall
and the piping or wrap 7 to 8 turns of
insulation vinyl tape around the piping.
To use existing piping, perform COOL
operation for 30 minutes and pump down
before removing the old air conditioner.

for new refrigerant.
Be sure to use wall hole sleeve (C) to
prevent indoor/outdoor connecting wire (A)
from contacting metal parts in the wall and
to prevent damage by rodents in case the
wall is hollow.
