configuration the effective length of the pipes is 6 m horizontally
and 4 m vertically, in total 10 m. We will then add 100 grams of
R410a refrigerant gas or 5 m x 20 g / m = 100 grams.

WARNING!
In fig. 5 we report an example of an inadmissible application,
with a distance of 10 meters but with a difference in height of> 5

(B) INSTALLATION WITH MINIMUM PERMISSIBLE LENGTH
The distance between the Indoor Unit and Outdoor Unit is less
than 3 meters (as in this case where the length of the pipes does
not exceed 2 meters), the pipes must be cut to 3 meters and
rolled up the final part in correspondence with the outdoor unit.
