  • Page 173 Amazon V 5.7 Piping Connections between Outdoor Units The piping connecting the outdoor units should be horizontal and must not be higher than the refrigerant outlets. If necessary, to avoid obstacles the piping may be vertically offset below the outlets. When inserting a vertical offset to avoid an obstacle, the whole outdoor piping should be offset, rather than just the section adjacent to the obstacle.
  • Page 174 Amazon V 5.8.2 Procedure Notes for installers  Warning Only use nitrogen for flushing.Using carbon dioxide risks leaving condensation in the piping.Oxygen, air, refrigerant, flammable gases and toxic gases must not be used for flushing.
