Charge Using the Refrigerant Cylinder with a Siphon
• This is usually applied to R32. Charge the refrigerant (gas phase) by standing the refrigerant cylinder.
NOTE
• Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them.
• Ensure that contamination of different refrigerants does not occur when using charging equipment.
• Extreme care shall be taken not to overfill the refrigerant system.
• Prior to recharging the system it shall be pressure tested with oxygen free nitrogen (OFN). The system shall
be leak tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out
prior to leaving the site.
• The handling of the refrigerant must comply with national regulations.
