1.2
General instructions
The system must satisfy each point in the rules in force in the country that
govern works and interventions in individual homes, blocks of flats or other
buildings.
Only qualified professionals are authorised to work on the appliance and
the heating installation. They must respect prevailing local and national
regulations during fitting, installation and maintenance of the installation.
Commissioning must be performed by a qualified professional.
1.3
Electrical safety
Before making any electrical connections, earth the appliance in
accordance with prevailing standards.
Danger
Danger of electric shock: the length of the conductors between the
traction arrester device and the terminal blocks must be such that
the active conductors are put under tension before the earth
conductor.
Only qualified professionals may carry out electrical connections, always
with the power off.
Separate the very low voltage cables from the 230/400 V power supply
cables.
1.4
Refrigerant safety
Warning
Refrigerant fluid and pipes:
Use only R410A refrigerant fluid to fill the installation.
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 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.
France: Pursuant to Article L. 113-3 of the French Consumer Code, the
equipment must be installed by a certified operator whenever the
refrigerant load is in excess of 5 tonnes of CO
2
equivalent or when a
refrigerant connection is necessary (the case with split systems, even
when fitted with a quick coupling device).
All work on the refrigeration circuit must be done by a qualified
professional, according to prevailing codes of practice and safety in the
profession (recovery of the refrigerant, brazing under nitrogen). All brazing
work must be done by qualified welders.
Do not touch the refrigeration connection pipes with your bare hands while
the heat pump is running. Danger of burn or frost injury.
In the event of a refrigerant leakage:
1. Switch off the appliance.
2. Open the windows.
3. Do not use a naked flame, do not smoke, do not operate electrical
contacts.
4. Avoid contact with the refrigerant. Danger of frost injuries.
