Caution
It is preferable to use HOLIDAYS mode rather
than switching off the heat pump to handle the
following functions:
Unblocking the circulating pumps,
frost protection.

Specific safety instructions
Warning
Refrigerant fluid and pipes:
Use only R410A refrigerant fluid to fill the instal
lation.
Use tools and pipe components especially de
signed 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
compressor).
Do not use a load cylinder.
Protect the heat pump components, including
the insulation and structural elements. Do not
overheat the pipes as brazed components may
cause damage.
Contact between the refrigerant fluid and a
flame may result in emissions of toxic gases.

Refrigerant fluid R410A
Hazard identification
Effects harmful to health:
The vapours are heavier than air and may lead to as
phyxia owing to reduced oxygen levels.
Liquefied gas: contact with the liquid may cause seri
ous frost burn and eye injuries.
Product classification: this product is not classified as
a "hazardous preparation" according to European Un
ion regulations.
If the R410A refrigerant is mixed with air, it may cause
pressure surges in the refrigeration pipes and lead to an
explosion and other hazards.
Composition of / Information on the ingredients
Chemical nature: R-410A is composed of Difluorome
thane R32 and Pentafluoroethane R125
