► Do not mix the prescribed coolant with coolants of another type or replace it with a
coolant of another type.
Danger of faults in the cooling circuit due to humidity and external gases
To avoid faults in the cooling circuit due to penetrating humidity or external gases, the system
must be evacuated before commissioning in all cases.
► The system must be evacuated in all cases before commissioning and a pressure test
be conducted.
► If the length of the coolant pipelines is greater than the pre-filled connection distance
of the device (→ 4 Technical data (split systems), p.
