2014/35/EU
2011/65/EU with its amendment (EU) 2015/863
1.2 Regulation (EU)
Stationary air conditioners within the European market and operating with fluorinated greenhouse gases (F-gas, such as
R407C, R134a, R410A), have to comply starting from 1st Jan, 2015 with the F-gas Regulation (EU) No. 517/2014 which replaces
the previous Re. (EU) no. 342/2006, valid from 4th since July, 2007.
Note that, the refrigerants like R22 are not F-gas and their relevant regulation is Reg. (EU) no. 2037/2000.
The following notes have to be considered when operating with the above mentioned systems:
Fluorinated greenhouse gases are covered by the Kyoto Protocol.
The fluorinated greenhouse gases in this equipment must not be released into the atmosphere.
The values indicated in Annex I and Annex IV of Regulation (EU) No 517/2014 concerning the global warming
potential (GWP) of some major F-gases or mixtures are given below:
R-134a GWP 1430
R-407C GWP 1774
R-410A GWP 2088
1 Important Safety Instructions 1
Proprietary and Confidential ©2023 Vertiv Group Corp.
Vertiv™ Liebert® CRV CRD25 and CRD35 User Manual
Operators of the above mentioned applications, which contain fluorinated greenhouse gases, shall, using all
measures which are technically feasible and do not entail disproportionate costs:
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 proper recovery of flourinated greenhouse gases by certified personnel.
d. In case of applications containing 5 tons CO2 equivalent, i.e. 2.4 kg of R410A (10 tons in case of
hermetically sealed system) or more of F- gases: certified personnel and Companies (according to Reg.
303/2008) provides 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. 8 of the Regulation shall take place before the final disposal of that equipment and, when
appropriate, during its servicing and maintenance.
Operator, according to Regulation 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.
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 sensitive of portable gas detection
devices (as a direct test method) shall be at least five grams per year.
b. Proprietary bubble solutions / soapsuds.
Additional information located into a dedicated label of unit (Reg. 1494/2007)
a. Where fluorinated greenhouse gas is foreseen to be added to the equipment outside of the manufacturing
site at the point of installation, a dedicated label accommodates notation of both the quantity (kg) pre-
charged in the manufacturing plant and of the quantity charged at the installation site as well as the
resulting total quantity of f-gas as a combination of the above mentioned quantities, in a manner which
conforms to the legibility and indelibility.
Our split units are usually not pre-charged on factory, in this case the total quantity of refrigerant charged
in the unit has to be written in the relevant label, during the commissioning operation at the installation
site.
b. Our packaged units (not split) operating with f-gas are usually full charged on factory and the total amount
of refrigerant charge is already reported on the label. In this case, the label has no need of further written
information.
c. In generally, the above mentioned information has been located in the main nameplate of relevant unit.
d. For equipment with double refrigeration circuits, in regards to differentiates requirements on the basis of
the quantity of f-gas contained, the required information about refrigerant charge quantities has to be
listed separately for each individual circuit.
e. For equipment with separate indoor and outdoor sections connected by refrigerant piping, the label
information will be on that part of the equipment which is initially charged with the refrigerant. In case of a
split system (separate indoor and outdoor sections) without a factory pre-charge of refrigerant, the
mandatory label information will be on that part of the product or equipment which contains the most
suitable service points for charging or recovering the fluorinated greenhouse gas(es).
Safety data sheets of f-gases used in the products are available on demand.

3 Pre-installation Preparation
WARNING! Risk of top-heavy unit falling over when improperly lifted or moved. Improper handling can cause
equipment damage, injury or death. Read all of the following instructions and verify that all lifting and moving
equipment is rated for the weight of the unit before attempting to move, lift, remove packaging from or
prepare the unit for installation.
CAUTION: Risk of contact with sharp edges, splinters, and exposed fasteners. Can cause injury. Only properly
trained and qualified personnel wearing appropriate, OSHA-approved PPE should attempt to move, lift,
remove packaging from or prepare the unit for installation.
NOTICE
Risk of passageway interference. Can cause unit and/or structure damage. The unit may be too large to fit
through a passageway while on or off the skid. Measure the unit and passageway dimensions, and refer to the
installation plans prior to moving the unit to verify clearances.
NOTICE
Risk of damage from forklift. Can cause unit damage. Keep tines of the forklift level and at a height suitable to fit
below the skid and/or unit to prevent exterior and/or underside damage.
NOTICE
Risk of improper storage. Can cause unit damage. Keep the unit in its original package, upright, indoors and
protected from dampness, freezing temperatures and contact damage.
