1.17 SYSTEM FILLING

Once the indoor unit is connected, fill the system using the filling cock (Par. 1.22).
The indoor unit has one incorporated automatic vent valve located on the circulator and another on the central heating manifold.
Make sure that the hoods are loosened.
The filling cock must be closed when the indoor unit pressure gauge indicates approximately 1.2 bar.
During these operations, enable the "Venting" functions by setting the "U 50" parameter to ON, which lasts about 18 hours
(Parag. 3.9).
System minimum water content.
Minimum water content favours the proper execution of defrosting cycles and operation in cooling mode.
To this end, the minimum amount of water to guarantee is 50 litres for any type of system and in any operating mode.
