Page 102: Precautions When Charging Refrigerant
Charging refrigerant WARNING The R744 refrigerant (CO ) inside the unit is odourless, non-flammable and normally does NOT leak. If the unit is installed indoors, ALWAYS install a CO detector according to the specifications of standard EN378. If the refrigerant leaks in high concentrations in the room, it may have negative effects on its occupants such as asphyxiation and carbon dioxide poisoning. - Page 103 Charging refrigerant CAUTION A vacuumed system will be under triple point. To avoid solid ice, ALWAYS start charging with R744 in vapour state. When the triple point is reached (5.2 bar absolute pressure or 4.2 bar gauge pressure), you may continue charging with R744 in liquid state.

Page 104: To Determine Additional Refrigerant Amount
Charging refrigerant NOTICE In case of maintenance and the system (outdoor unit+field piping+indoor units) does not contain any refrigerant any more (e.g., after refrigerant reclaim operation), the unit has to be charged with its original amount of refrigerant (refer to the nameplate on the unit) and the determined additional refrigerant amount. - Page 105 Charging refrigerant Calculation table: outdoor unit with or without capacity up unit Amount of refrigerant for liquid piping (refrigeration / air conditioner) Liquid piping Conversion Piping length Total amount size (mm) ratio per of refrigerant meter of (kg) liquid piping (kg/m) Ø9.5 0.0463...
