SystemAir AC-RSR105R32HEC, Installation And Maintenance Manual

Page: 16 / 79

This equipment contains fluorinated gas with greenhouse gas effects covered by the Kyoto
agreement.
Caution
SYSAER R32 units use the R32 HFC refrigerant which is a flammable gas classified A2L (Slightly
flammable). This gas is a subject to more important safety regulations due to their flammability
class A2L Reduced flammability so some precautions are required to prevent accidental build-up of
refrigerant. Particularly during charging of systems. Manufacturers recommend use of extract fans
while charging, particularly if the outdoor unit is used in an enclosed area. The standard EN378
defines requirements for safe concentration levels of the refrigerants.
Caution
Non-compliance with one of these obligations constitutes an offense and can result in financial
penalties.
Furthermore, compliance of the equipment with the fluorinated gases regulation must be proven to
the insurance company.

8.2. REFRIGERATION SPECIFICATIONS
8.2.1. REFRIGERANT CIRCUIT DIAGRAM
SEE APPENDIX
8.2.2. REFRIGERANT CHARGE
The type and quantity of refrigerating fluid per circuit are indicated on the product plate.
The installer and end user will get informed on local environmental regulations for the installation, operation
and disposal of the equipment ; more particularly, for the collection of substances hazardous for the
environment (refrigerating fluid, oil, antifreeze, etc.). A refrigerating fluid, whatever it is, must not be vented.
Refrigerating fluids must be handled by skilled personnel.
8.2.3. FLUOROCARBON GAS REGULATIONS
The EC No. 517/2014 regulation covering fluorinated greenhouse gases requires of refrigeration equipment
operators to comply with the following five obligations:
1. Installation, servicing, maintenance as well as checking the sealing must be carried out by qualified
personnel.
2. The fluorinated gas must be recovered during servicing and maintenance as well as the end of the
installation.
3. All the necessary measures must be taken to prevent the leakage of fluorinated gases and any leaks
must be repaired as rapidly as possible.
4. Regular checks on any leaks must be performed according to the following conditions:
for equipment containing fluorinated greenhouse gases in quantities greater than or equal to
the equivalent of 5 tonnes of CO
2
but less than the equivalent of 50 tonnes of CO
2
:
at least every twelve months or, if a leak detection system is installed, at least every twenty-
four months
for equipment containing fluorinated greenhouse gases in quantities greater than or equal to
the equivalent of 50 tonnes of CO
2
but less than the equivalent of 500 tonnes of CO
2
:
at least every six months or, if a leak detection system is installed, at least every twelve
months
for equipment containing fluorinated greenhouse gases in quantities greater than or equal to
the equivalent of 500 tonnes of CO
2
:
at least every three months or, if a leak detection system is installed, at least every six
months.
5. A document grouping a description of all the operations carried out on the cooling circuit must be
drafted and conserved.
