2 .7 .3 Additional charge
The charge in the outside units corresponds to the maximum distances between the outside unit and the hydraulic
module defined in page
charge depends on the distance between the outside unit and the hydraulic module for each type of appliance.
The additional charge of R410A must necessarily be made by an approved refrigeration engineer.
7.5m < Length of the connections ≤ 15m
[0.03 x (Length of the connections - 7.5) + 0.175] x 1000 = g
If the temperature control set on the hydraulic module is less than or equal to 0.4, an additional charge must be
added from 5m refrigerant piping according to the formula: 0.03 x (length of the connections - 5) + 0.1.
