1.3.1 Refrigerant fluid R410A

Hazard identification
Effects harmful to health:
The vapours are heavier than air and may lead to asphyxia
owing to reduced oxygen levels.
Liquefied gas: contact with the liquid may cause serious
frost burn and eye injuries.
Product classification: this product is not classified as a
"hazardous preparation" according to European Union reg­
ulations.
If the R410A refrigerant is mixed with air, it may cause pres­
sure surges in the refrigeration pipes and lead to an explo­
sion and other hazards.
Composition of / Information on the ingredients
Chemical nature: R-410A is composed of Difluoromethane
R32 and Pentafluoroethane R125
Proportion
50%
The Global-Warming Potential of R410A gas is 2087.5.
Warning
Refrigerant fluid and pipes:
Use only R410A refrigerant fluid to fill the installa­
tion.
Use tools and pipe components especially designed
for use with R410A refrigerant fluid.
Use copper pipes deoxidised with phosphorus to
carry the refrigerant fluid.
Store the refrigerant connection pipes away from
dust and humidity (risk of damage to the compres­
sor).
Do not use a load cylinder.
Protect the heat pump components, including the in­
sulation and structural elements. Do not overheat
the pipes as brazed components may cause dam­
age.
Contact between the refrigerant fluid and a flame
may result in emissions of toxic gases.
