Maintenance
Liebert® CRV™112
14.8 Dismantling the Unit
The Liebert CRV has been designed and built to ensure continuous operation.
The working life of some of the main components, such as the fan and the compressor, depends on
proper maintenance.
NOTICE
Risk of release of hazardous substances into the environment. Can cause environmental
pollution and violation of environmental regulations.
The Liebert CRV contains substances and components hazardous for the environment
(electronic components, refrigerating gases and oils). At the end of its useful life, the
Liebert CRV must be dismantled by specialized refrigerating technicians. The unit must be
delivered to suitable centers specializing in the collection and disposal of equipment
containing hazardous substances.
The refrigerating fluid and the lubricating oil inside the circuit must be recovered according to the
laws in the relevant country.
To recover the gas, use all the connections described in 6.0 Refrigerant Connections.
14.9 F-Gas Regulation (EC) No. 842/2006
Stationary air conditioning placed in the European Community market and operating with
fluorinated greenhouse gases (F-gas), such as R-134A, R-407C and R-410A, must comply with the F-
gas Regulation (applied since July 4, 2007).
Following considerations must be observed when operating with the above-mentioned equipment:
• Fluorinated greenhouse gases are covered by the Kyoto Protocol.
• The fluorinated greenhouse gases in this equipment should not be vented to the atmosphere.
• Referring to the value noted in Annex I of Regulation (EC) No 842/2006, the following list speci-
fies the global warming potential (GWP) of some major F-gases:
• R-134A: GWP 1300
• R-407C: GWP 1610
• R-410A: GWP 1890
• Operators of the above-mentioned applications, which contain fluorinated greenhouse gases,
shall, using all measures that 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 arrangements are put in place for the proper recovery by certified personnel.
d. In case of applications containing 3 kg (6 kg in case of hermetically sealed systems) or more of
F-gases, certified personnel and companies (according to Reg. 303/2008) provide regular leak
testing (according to Reg. 1516/2007 and Reg. 1497/2007) and maintain records of
maintenance activities in a dedicated log book.
e. Recovery for the purpose of recycling, reclamation or destruction of the fluorinated
greenhouse gases, pursuant to Art. 4 (Recovery) of Reg.842/2006, shall take place before the
final disposal of that equipment and, when appropriate, during its servicing and
maintenance.
• Operator, according to Reg. 842/2006, Article 2, point 6, means the natural or legal person exercis-
ing actual power over the technical functioning of the equipment and system covered by the Regu-
lation. The State may, in defined, specific situations, designate the owner as being responsible for
the operator's obligations.
• Direct methods of leakage checking approved by the manufacturer (Reg. 1516/2007 and Reg.
1497/2007):
a. gas detection device adapted to the refrigerant in the system; the sensitivity of portable gas
detection devices (as a direct test method) shall be at least five grams per year.
b. proprietary bubble solutions / soapsuds.
