6. 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.
• Pay close attention to the directions in Figure 16 when performing drain work.
• 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 while referring to Fig. 18.
• Select diameter of drain piping that 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 filter, pouring water
into the drain pan, and making sure water
flows smoothly out of the drain hose.
