1.3 Specific safety instructions
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.
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.
