7.4.4 Operators
7.4.4.1 De initions
• Operator, according to Regulation 517/2014 Article 2, point 8, means the natural or legal person exercising actual power over
the technical functioning of products and equipment covered by this Regulation.
• The State may, in defined, specific situations, designate the owner as being responsible for the operator's obligations.
• Where large installations are involved, service companies are contracted to carry out maintenance or servicing. In these
cases the determination of the operator depends on the contractual and practical arrangements between the parties.
7.4.4.2 Obligations
Operators of stationary air conditioners, which contain fluorinated greenhouse gases, shall, using all measures which are
technically feasible and do not entail disproportionate cost:
a
Prevent leakage of these gases and as soon as possible repair any detected leakage.
b Ensure that they are checked for leakage by certified personnel.
c Ensure for putting in place arrangements for the proper recovery by certified personnel.
d According to Regulation 517/2014 the operators shall ensure that the equipment is checked for leaks as following:
Case 1 - Non-sealed equipment contains less than 5 tonnes of CO 2 equivalent of fluorinated greenhouse gases.
► Leakage test not required
Case 2 - Hermetically sealed equipment contains less than 10 tonnes of CO 2 equivalent of fluorinated greenhouse
gases.
► Leakage test not required
Case 3
► Leakage test required: check the equipment for leaks with the minimum frequency given in the following table:
X = Tonnes of
CO2 Equivalent
5 ≤ X < 50
50 ≤ X < 500
X ≥ 500
e
Recovery for the purpose of recycling, reclamation or destruction of the fluorinated greenhouse gases, pursuant to Art.
8 of the Regulation 517/2014 shall take place before the final disposal of that equipment and, when appropriate, during
its servicing and maintenance.
7.4.5 Leakage Detection
The manufacturer approves the following leakage check methods according to Reg. 1516/2007 and Reg. 1497/2007:
Method
a Check of circuits and components representing a risk
of leakage with gas detection devices adapted to the
refrigerant in the system
b Application of ultraviolet (UV) detection fluid or suitable
dye in the circuit
c Proprietary bubble solutions/soapsuds
Y = equivalent amount of refrigerant [kg]
R134a R410A
3,5 ≤ Y < 35 2,4 ≤ Y < 24
35 ≤ Y < 350 24 ≤ Y < 240
Y ≥ 350 Y ≥ 240
Minimum frequency for leak check

detection
2,8 ≤ Y < 28 12 Months
28 ≤ Y < 282 6 Months
Y ≥ 282 3 Months
Specifications
Gas detection devices shall be checked every 12 months to
ensure their proper functioning.
The sensitivity of portable gas detection devices shall be at
least five grams per year.
The method shall only be undertaken by personnel
certified to undertake activities which entail breaking into
the refrigeration circuit containing fluorinated greenhouse
gases.
