6	Remove fluid reservoir (4)	Installation:  Use new fluid reservoir (4). Installation:  The packaging of the new fluid reservoir (4) must be undamaged. Once the packaging of the new fluid reservoir (4) has been opened, it must be installed within 20 minutes and the entire refrigerant circuit sealed, as otherwise the function of the fluid reservoir (4) can no longer be guaranteed. Installation:  Replace sealing ring of refrigerant line and wet with compressor oil.
7	Use suitable plug to seal opening of refrigerant line and suitable stop plug to seal opening of fluid reservoir (4)	The opening of the refrigerant line and fluid reservoir (4) must be closed otherwise dirt and moisture ingress damages the components which are connected to the refrigerant circuit.
8	Install in the reverse order
