(Assume eqivalent pipe length of REFNET joint to be 0.5m, that of REFNET header to be 1m, that of BSVQ100, 160 to be 4m, that of BSVQ250 to be 6m for calculation purposes)
Total piping length from outdoor unit (*2) to all indoor unit ≤ 1000m
Actual pipe length from first outdoor unit multi connection piping kit to outdoor unit ≤ 10m
Equivalent pipe length from first outdoor unit multi connection piping kit to outdoor unit ≤ 13m
Actual pipe length from first refrigerant branch kit (either REFNET joint or REFNET header) to indoor unit ≤ 40m (Note 2)
Example 8 : b + c + d + e + s ≤ 40m
Difference in height between outdoor unit and indoor unit (H1) ≤ 50m (Max 40m if the outdoor unit is below)
Difference in height between adjacent indoor units (H2) ≤ 15m
