Precautions for humidifying hose installation work.
• Moisture on the outdoor unit is brought to the indoor unit together with air around the outdoor unit during humidifying
operation. Install the outdoor unit in a clean and calm location.
• When embedding humidifying hose:
1) Cannot be installed to the existing embedded piping. Embedding work is separately necessary.
• The length of the humidifying hose is marked on the hose packing material.
1) Use an extension hose (sold separately) when extending the humidifying hose.
2) The length of the humidifying hose needs to be set to ensure humidifying capacity. Cut off any excess hose.
Use the remote controller to set the hose length.
• When it is difficult to install without cutting the humidifying hose, cut the hose and join it with included joint or elbow
after the installation. When doing this, bind the hose using included binding band so that there is no air leakage.
(Refer to
Connecting the Humidifying Hose on page 8.)
• When laying the humidifying hose inside the wall, block the ends of the humidifying hose with tape or the like to
prevent water or anything else from entering it until it is connected to the indoor unit and outdoor unit ducts.
• Do not bend the humidifying hose more than 90°.
