1. 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.
• Be sure to use the humidifying hose sold as an optional accessory. (KPMH996A10S (10m set), KPMH996A15S (15m set))
CAUTION
Do not connect the embedded branch piping and the outdoor unit when only carrying out piping work without connecting the
indoor unit in order to add another indoor unit later.
Make sure no dirt or moisture gets into either side of the embedded branch piping.
See "Precautions for Laying Refrigerant Piping" on page 9 for details.
