This is the sum of the main and both branch pipes and is used when
calculating the refrigerant charge.
This is used as the maximum resistance which can be imposed on a
system and takes into account pipe fittings and bends.
Only required if Maximum Pipe Length (L1+L2+L3) is greater than 20m,
please refer to page 28 entitled 'Additional Refrigerant' for more details.
