SPECIFICATIONS
*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.
*3 Never use pipes with thickness less than specified. The pressure resistance
will be insufficient.
*4 Use a copper pipe or a copper-alloy seamless pipe.
*5 Be careful not to crush or bend the pipe during pipe bending.
*6 Refrigerant pipe bending radius must be 100 mm or more.
*7 Insulation material : Heat resisting foam plastic 0.045 specific gravity
*8 Be sure to use the insulation of specified thickness. Excessive thickness may
cause incorrect installation of the indoor unit and insufficient thickness may
cause dew drippage.

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.
Remake flare according to the dimension
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.

Drain piping for outdoor unit
Install the unit horizontally.
Do not use drain socket in cold regions.
Drain may freeze and make the fan stop.
The outdoor unit produces condensate
during the heating operation. Select the in-
stallation place to ensure to prevent the
outdoor unit and/or the grounds from being
wet by drain water or damaged by frozen
drain water.
