*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 If pipe length exceeds 7 m, additional refrigerant (R410A)
charge is required. (No additional charge is required for
pipe length less than 7 m.)

*8 Insulation material : Heat resisting foam plastic 0.045 spe-
cific gravity
*9 Be sure to use the insulation of specified thickness. Exces-
sive thickness may cause incorrect installation of the indoor
unit and insufficient thickness may cause dew drippage.
Cut off
the extra
length.
After the leak test, apply
insulating material tightly
so that there is no gap.
When the piping is to be
attached to a wall contain-
ing metals (tin plated) or
metal netting, use a chemi-
cally treated wooden piece
20 mm or thicker between
the wall and the piping or
wrap 7 to 8 turns of insula-
tion vinyl 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
according to the dimension
for new refrigerant.

Drain piping for outdoor unit
<MSH 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 downhill grade for easy drain flow.
(I) Note:
Install the unit horizontally.
Do not use drain socket (8) 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.
