CONDENSATE DRAIN
1. Be sure the unit is reasonably level and pitched toward the drain to ensure proper drainage.
2. Connect the condensate drain pipe to the coupling, see Fig.9.
3. The indoor unit uses gravity to drain; therefore the piping outside the unit should slope
downward.
4.
“Important”, avoid draining as shown in Fig.10, A, B, C. Follow proper draining as shown in
Fig.10D.
