8.3.3 Space heating pipes connection
The unit is factory supplied with two shut-down valves to be connected to the water inlet/outlet
pipe. With these shut-down valves it is very practical to connect the indoor unit to the heating
system by using the factory supplied gaskets just below the valves (2-3HP: G 1”; 4-6HP: G 1-1/4”).
Then, the space heating installation can be carried out.
