Inappropriate piping work may result in water
leakage in the room and wet of furniture.
Piping / Heat insulating material
Require the following materials for piping and heat
insulating at site.
Hard vinyl chloride pipe VP25
Piping
(Outer dia.: Ø32 mm)
Foam polyethylene:

Thickness 10 mm or more
Flexible hose
Use the attached flexible hose to adjust centre
discrepancy of the hard vinyl chloride pipe or to adjust
the angle.
• Do not use the flexible hose as stretched, or do not

REQUIREMENT
• Perform heat insulation of the drain pipes of the indoor
unit.
• Perform heat insulation of the connecting part with the
indoor unit.
An incomplete heat insulation causes dew drop.
• Set the drain pipe with downward slope (1/100 or
more), and do not make swelling or trap on the piping.
It may cause an abnormal sound.
• For length of the traversing drain pipe, restrict to 20 m
or less.
To use a long pipe, provide support brackets with
interval of 1.5 - 2 m in order to prevent waving.
