– 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 1: 50 to prevent leakage. Figure 23 shows the unit in the floor mounted position.
– When the drain hose is placed in the room, insulate the hose with foam polyethylene to
avoid damage to the ceiling or furniture.
– After completing installation of refrigerant lines, wiring and drain connections, bind the
tubing, wiring and drain hose -(check if local codes permit binding) into a bundle by using
tape at 100 or 200 mm (4" to 8") intervals. Make sure the drain hose is at the bottom of the
bundle (Figure 24).
