leakage in the room and wet of furniture.
 Piping / Heat insulating
material
Screws
Require the following materials for piping and heat
insulating at site.
Hard vinyl chloride pipe VP25
Piping
(Outer dia. : Ø1.3" (32 mm))
Foam polyethylene :

Thickness 0.4" (10 mm) or more
 Flexible hose
Use the attached flexible hose to adjust center
discrepancy of the hard vinyl chloride pipe or to adjust
the angle.
• Do not use the flexible hose as stretched, or do not
