*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. The unit
shall be installed in accordance with national wiring regulations.
*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 If pipe length exceeds 7 m, additional refrigerant (R410A)
charge is required. (No additional charge is required for
pipe length less than 7 m.)

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.
After the leak test, apply
insulating material tightly
so that there is no gap.
When the piping is to be at-
tached 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 vi-
nyl tape around the piping.
To use existing piping, per-
form COOL operation for
30 minutes and pump down
before removing the old air

conditioner. Remake flare
or more
according to the dimension
for new refrigerant.

Note:
Install the unit horizontally.
Do not use drain socket (10) in cold regions. Drain may freeze and
make the fan stop.
The outdoor unit produces condensate during the heating operation.
Select the installation place to ensure to prevent the outdoor unit and/
or the grounds from being wet by drain water or damaged by frozen
drain water.

Drain piping for outdoor unit
<VA type only>
• Provide drain piping before indoor and
outdoor piping connection.
• Connect drain hose (I) I.D.15 mm as
shown in the illustration.

• Choose one hole for draining, and install
drain socket (10). Close the remaining
two holes with drain cap (11).
• Make sure to provide drain piping with a
downhill grade for easy drain flow.
