– High and low pressure pipes:
• The High Pressure and Low Pressure pipes are composed of rigid aluminium pipes and flexible pipes which
enable engine-related movements to be absorbed.
• Two filler valves (on the High Pressure pipe and on the Low Pressure pipe) can be accessed in order to fill
(or drain) the refrigerant loop.
• The connections must be checked in the event of a refrigerant fluid leak.
