DRAIN PIPING WORK

(1) Install the drain piping. (Refer to Fig. 16)
• The drain pipe should be short with a downward slope and should prevent air pockets from forming.
• Watch out for the points in the fi gure 16 when performing drain work.
Make sure the drain
hose is at a downward
slope.
• When extending the drain hose, use a commercially available drain extension hose, and be sure to
insulate the extended section of the drain hose which is indoors. (Refer to Fig. 17)

• Make sure the diameter of the extension drain piping is the same as the indoor unit drain hose (hard
vinyl chloride, I.D. 9/16") or bigger.
• In case of converging multiple drain pipes, install them referring to Fig. 18.
• Select diameter of drain piping which adapts to the capacity of the unit connected.
(2) Make sure the drain works properly.
• After drain work is complete, perform a drain
check by opening the front panel, removing
the air fi lter, pouring water into the drain pan,
and making sure water fl ows smoothly out of
the drain hose. (Refer to Fig. 19)
