37.1 Responsibilitiesoftheoperator
As part of the Kyoto Protocol, the European Union is committed to reducing the emissions of fluorinated greenhouse
gases. To this end, EC Regulation No. 517/2014 of 16/04/2014 has been adopted. The overriding goal of this F-gas
Regulation is to reduce emissions of fluorinated greenhouse gases over the entire life cycle of these gases.
InaccordancewithECRegulationNo.517/2014,theowner/operatorhasthefollowingobligations:
37.1.1 Annualtightness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 tightness 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 tightness
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 tightness test is detailed in the following table.

Conversion to charge weight CO2 equivalent mass:
Refrigerant charge 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 tightness test may only be carried out by certified contractors/refrigeration engineers in accordance with
EC 842/2006, 303/2008 and 517/2014.
