Drain Hose Guidelines
Refer to the diagrams below and follow proper installation and the running of the drain hose along the pipe installation line to avoid leakage. Once
drain hose is set in place, always follow with evacuation and leakage testing of all piping to be sure all piping is properly sealed. Re-check and retest
as necessary.
Drain hose is routed from the indoor unit through the structure
(wall) to the outdoor. It should slope at an angle where it is high-
er at the indoor unit and lower toward the outdoor area, thereby
letting gravity push any condensation down and out. See Figure
44 for proper drainage slope. Avoid piping the drain hose as
shown in Figure 45. These methods are incorrect and can cause
leakage at the indoor unit site.
