For refrigerant charge purposes, consider only the liquid line; ignore the vapor line(s).
The system will stop operation due to excessive or insufcient refrigerant, therefore, always charge the unit properly. When servicing, always
refer to any notes about system piping length and additional refrigerant amounts.
