The unit works with R32 refrigerant, which is included in the list of greenhouse gases (GWP 675) which are subject to the
requirements in EU regulation n. 517/2014 called “F-GAS” (mandatory in the European zone). Among the provisions of this
regulation, it sets forth that operators working on systems running with greenhouse gases be in possession of a certification,
issued or acknowledged by the competent authorities, attesting that they have passed a test authorising them to perform this
work. In particular
Up to 3kg total refrigerant in the appliance: category 2 certification.
3kg and more total refrigerant in the appliance: category 1 certification.
The gaseous form of R32 refrigerant is heavier than air and if released into the environment, most of it tends to concentrate in
poorly ventilated areas. Inhaling it can cause dizziness and sensations of suffocation and can develop lethal gas if in contact with
naked flames or hot objects (see the refrigerant’s safety data sheet in paragraph 4.4.
Pay attention to the fact that refrigerant fluids can be odourless
For any operation on the heat pump system:
Wear the appropriate PPE (specifically gloves and goggles).
Make sure that the workplace is well ventilated. Do not work in closed environments or ditches with little air
circulation.
Do not operate on the refrigerant in the vicinity of hot parts or naked flames.
Do not release the refrigerant into the environment and pay special attention to accidental leakage from pipes
and/or fittings even after having emptied the plant.
