53. System log book
As part of the Kyoto Protocol, the European Union is committed to reducing the
emissions of fluorinated greenhouse gases. To this end, EC Regulation 517/2014
of 16/04/2014 has been adopted. The overriding goal of this F Gas Regulation is to
reduce F gas emissions over the entire life cycle of these gases.
53.1 Responsibilities of the
operator
In accordance with regulation (EC) no. 517/2014, the owner/operator has the
following obligations:
53.1.1
Annual leak test
In accordance with Article 4, systems which contain more than 3 kg of refrigerant
and which are not hermetically sealed or, as of 2017, systems with a CO2 equivalent
mass of 5 t or more, must undergo an annual leak test. For systems containing
less than 3 kg of refrigerant, but with a CO2 equivalent mass of more than 5 t, a
transitional period applies until 31/12/2016. From 01/01/2017, these systems will then
be required to undergo an annual leak test.
Wolf split heat pumps use F-gas R410A, an HFC mixture with a global warming
potential (GWP100) of 2088. This means that 1 kg of R410A equates to 2.088 t of
CO2.
Which Wolf split heat pumps require a leak test is detailed in the following table.

Conversion to charge weight CO2 equivalent mass:
Refrigerant weight x GWP100 = Charge weight as CO2 equivalent mass
Example: 2.15 kg R410A * 2088 kg CO2 = 4489 kg CO2 = 4.49 t CO2
The leak test may only be carried out by certified contractors/refrigeration engineers in accordance with
EC 842/2006, 303/2008 and 517/2014.
Important:
This regulation also applies to systems which were sold/installed before 01/01/2015.
