5.4 Risk of explosion
When you install cut-off devices (solenoid valves, taps, etc.), be aware that they may cause traps for refrigerant in the form of closed zones
upstream and downstream where the refrigerant cannot freely expand.
In this situation, if there is an increase in temperature (due to exposure to the sun, proximity of pipes or sources of heat), the expansion of the
trapped gas may cause the refrigeration pipes to explode.
Evaluate whether safety valves can be installed, especially in the liquid pipes that are most exposed to this risk.
5.5 Supply line
Insulate only if you want to prevent burns due to accidental contact.

Additional indicative refrigerant charge for equivalent lengths greater than 5 metres.
Diameter of the Refrigerant line tubing equal to that of the inlet/outlet of the unit.
The final charge is to be the sum of the charge of the evaporating unit, the refrigerant piping and the condensate unit (being the responsibility of the Customer)..
The values shown in the tables are indicative and are to be evaluated throughout the installation phase.
