DRAIN PIPING WORK

• 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 droping.
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.
Piping
Heat insulator
„ 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 deform it more extent than that in the
following figure.
• Be sure to fix the soft end of the flexible hose
with the attached hose band.
• Use the flexible hose on a horizontal level.
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 dew droping.
• 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 20m or less.
In case of a long pipe, provide support
brackets with interval of 1.5 to 2m in order to
prevent waving.
• Set the collective piping as shown in the below
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.
