4DRAIN PIPING WORK
CAUTION
• Following the Installation Manual, perform the
drain piping work so that water is properly drained,
and apply a heat insulation so as not to cause a dew.
Inappropriate piping work may result in water
leakage in the room and wet of furniture.
nPiping/Heat insulating material
Require the following materials for piping and
heat insulating at site.
Piping
Heat insulator
Hard vinyl chloride pipe VP25
(Outer dia. : Ø1.3” (Ø32mm))
Foam polyethylene :
Thickness 0.4” (10mm) or more
REQUIREMENT
• Be sure to perform heat insulation of the drain pipes of the indoor unit.
• Never forget to perform heat insulation of the connecting part with the indoor unit.
An incomplete heat insulation causes dewing.
• 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 65’ 7” (20m) or less.
In case of a long pipe, provide support brackets
with interval of 4’ 11” to 6’ 7” (1.5m – 2m) in
order to prevent waving.
• Set the collective piping as shown in the right figure.
• Be sure not to apply force to the connecting part of the drain pipe.
• The hard vinyl-chloride pipe cannot be directly connected to the drain pipe connecting port of the indoor unit.
For connection with the drain pipe connecting port, be sure to use/fix the attached flexible hose with the hose
band, otherwise a damage or water leak is caused on the drain pipe connecting port.
Adhesive inhibited :
Use the attached flexible hose and hose band for connecting the drain hose to the drain piping connecting part.
If applying the adhesive, socket will be damaged and cause water leakage.
