Units should be installed by licensed
contractor according to local code
requirements.
After the leak test, apply insulating material tightly so that there is no gap.
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.

100 mm or more
No obstruction
100 mm or more
*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 bend-
ing.
*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.)
Additional refrigerant = A × (pipe length (m) – 7)
*8 Insulation material : Heat resisting foam plastic 0.045
specific gravity
*9 Be sure to use the insulation of specified thickness. Ex

cessive thickness may cause incorrect installation of the
indoor unit and insufficient thickness may cause dew drip

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.
Drain piping for outdoor unit
<VE type only>
• Provide drain piping before indoor and outdoor
piping connection.
• Connect drain hose (I) I.D.15 mm as shown in
the illustration.
• Make sure to provide drain piping with a down-
hill grade for easy drain flow.

note:
Install the unit horizontally.
Do not use drain socket (14) 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.
IMPoRtant notEs
To comply with the requirements
of Australian standard AS/NZS
3000 electrical installations (wir-
ing rules), the electrical wiring
required between the indoor and
outdoor units must be installed by
a licenced electrical contractor.
