Example of total additional charge calculation
Formula
∆W(g) = [Lenght of pipes (m) -
Precharge lenght (m)] x additional charge (g/m)
Example
Outdoor unit = MXZ-3E68VA
Total pipes lenght (inlet piping only) = 45 m
Lenght with additional charge (as tab) = 40 m
Additional charge = 20 g/m
Calculation: ∆W(g) = [45 - 40] x 20 = 100 g
