7. DRAIN PIPING WORK
(1) Carry out drain piping.
Carry out drain piping so that drainage can ensured.
•
Select the piping diameter equal to or larger than
(except for riser) that of the connection piping (polyvinyl
chloride piping, nominal diameter 25 mm, outside
diameter 32 mm).
•
Install the drain piping as short as possible with down-
ward inclination of 1/100 or more and without where air
may stagnate.
(Refer to Fig. 14) (It may cause abnormal
sound such as bubbling noise.)

CAUTION
If drain stagnates in the drain piping, the piping may be
clogged.
CAUTION
Using old drain hose, clamp fixture may cause water
leakage.
•
If
downward inclination cannot be ensured,
carry out upward drain piping.
•
Install supports at a distance of 1 to 1.5 m so that the
piping may no
t deflect.
(Refer to Fig. 14)
•
•
Make sure to use the attached drain hose (1) and the
metal clamp (2).
Insert the drain hose (1) into the drain socket up to the
point where the socket diameter becomes larger.
Put the metal clamp (2) to the taped hose end and
tighten the metal clamp (2) with torque 1.35±0.15 N·m
(135±15
N·cm).
CAUTION
•
Do not tighten the metal clamp (2) with the torque more
than the
value.
The drain hose (1), the socket or the metal clamp (2) may
be damaged.

piping (Refer to Fig. 16) >
•
The maximum height of the drain riser is 675 mm.
Since the drain pump mounted on this indoor unit is a high
head type, from the characteristic point of view, the higher
the drain riser the lower the draining noise.
Therefore, the drain riser of 300 mm or higher is
recommended.
•
For upward drain piping, keep the horizontal piping
distance of 300 mm or less between the drain socket root
to the drain riser.

Keep the drain hose level or make a slight up-grade so
that air may not stagnate in the drain hose.
If air stagnates, the drain ma

the drain pump stops and generate abnormal sound.
