List of operations to be performed before connection

Calculate the volume of water in the heating circuit and check the volume
of the appropriate expansion vessel using the DTU 65–11. Use the
maximum temperature of the circuit in heating mode or, failing that, a
minimum of 55 °C. If the volume of the integrated expansion vessel (10 l)
is not sufficient, add an external vessel to the heating circuit.
Connect the heating return for the indoor module. Place the pressure
gauge and its pipe on the heating return. The pressure gauge is supplied
with the indoor module.
Connect the heating flow for the indoor unit.
