8.3 Connection of piping
• Preparing the indoor unit's piping and drain hose for installation through the wall.
1.
Route the indoor tubing and the drain hose in the direction of rear left or right
2.
Tape the tubing, drain hose and the connecting cable. Make sure that the drain hose is located at the
lowest side of the bundle. Locating at the upper side can cause drain pan to overflow inside the unit.
Note
• If the drain hose is routed inside the room, insulate the hose with an insulation material* so that dripping from
condensation will not damage furniture or floors.
• Foamed polyethylene or equivalent is recommended.
