Whereas:

| (1) | Pursuant to Regulation (EC) No 842/2006, records for refrigeration, air conditioning and heat pump equipment shall contain certain information. In order to ensure the effective implementation of Regulation (EC) No 842/2006, it is appropriate to provide for further information to be indicated in the equipment records. |

In order to ensure an efficient leakage control, the leakage checks should focus on those parts of the equipment which are most likely to leak.

| (5) | Leakage checks should be carried out using direct or indirect measuring methods. Direct measuring methods identify leakage by the use of detection devices which can determine whether the fluorinated greenhouse gas charge is escaping from the system.
