Installation
3. Tape the tubing pipe, drain hose and the connection cable. Be sure that the drain hose is located
at the lowest side of the bundle. Locating at the upper side can cause overflow from the drain pan
through the inside of the unit.
If the drain hose is routed inside the room insulate the hose with an insulation material* so that
dripping from sweating (condensation) will not damage furniture or floors.
* Foamed polyethylene or equivalent is recommended.
