Routing the Drain Hose for Indoor Unit

Drain hose is routed from the indoor unit, through the structure (wall) to the outdoors. The hose should
slope at an angle where it is higher at the indoor unit and lower at the outdoor area, letting gravity push
condensation down and out. Figure 5-19 shows the proper drainage slope. Figure 5-20 shows incorrect
methods of routing the drain hose, which cause leakage at the indoor unit.
