• The maximum height of the drain riser is 467 mm. Since
piping (Refer to Fig. 13) >
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.
