5-3. Selecting the Refrigerant Line Material
• Refrigerant pipes
• Material: Phosphoric deoxidized seam-less pipe
• Capacity code of outdoor unit / indoor unit
• For each indoor unit, the capacity code is determined for every capacity rank.
• For each outdoor unit, the capacity code is determined for every capacity rank. The Max. number of the
connectable indoor units and the total capacity code value of the indoor units are also determined.
Against the capacity code of the outdoor unit, the total capacity codes of the connectable indoor units differ
according to the height difference between indoor units.
• When the height difference between indoor units is 15m or less: Up to 135% of capacity code of outdoor unit
• When the height difference between indoor units is 15m or more: Up to 105% of capacity code of outdoor unit
