Drain piping

1) Connect the drain hose, as described right.
2) Remove the upper front panel and the air filters.(Refer to removal method on page 4.)
Pour some water into the drain pan to check the water flows smoothly.
3) When drain hose requires extension, obtain an extension hose with an inner
diameter of 16mm.
Be sure to thermally insulate the indoor section of the extension hose.
4) When connecting a rigid polyvinyl chloride pipe
(nominal diameter 13mm) directly to the drain
hose attached to the indoor unit as with
embedded piping work, use any commercially
available drain socket (nominal diameter 13mm)
as a joint.
