- The drain hose should run straight
down the wall to a level where the
runoff will not stain the wall.
- There should be no traps.
- Avoid putting the end of the
hose in water.
- To conveniently drain the system,
the drain hose must slant
downward, with a slope of at least

the room, insulate the hose with
foam polyethylene to avoid
