Be sure to maintain a posture that does not cause fatigue when installing and maintaining the
unit. Also check the weight of any component before handling it.
The unit works with the refrigerant R32, included in the list of greenhouse gases (GWP
675) that meet the requirements of EU Regulation No. 517/2014 known as “F-GAS”
(mandatory in the European area). One of the provisions of this Regulation requires
operators working in installations using greenhouse gases to hold a certificate issued or
recognised by the competent authority attesting that they have passed an examination
authorising them to carry out such work. In detail :
- Up to 3 kg of total refrigerant contained in the appliance: Category 2 certificate.
- More than 3 kg of total refrigerant contained in the appliance: category 1 certificate.
Refrigerant R32 in gaseous form is heavier than air, if it is dispersed in the environment,
it tends to concentrate strongly in poorly ventilated areas. Inhalation can cause dizziness
and suffocation and, in case of contact with open flames or hot objects, lethal gases may
be emitted (see Refrigerant Material Safety Data Sheet).
You should know that refrigerants may not develop an odor.
For any intervention on the heat pump system:
Wear appropriate PPE (especially gloves and goggles).
Ensure that the workplace is well ventilated. Do not work in closed rooms or ditches with low
air recirculation.
Do not handle coolant near hot components or open flames.
Avoid any dispersion of the refrigerant in the environment and pay particular attention to
accidental leaks of pipes and/or fittings, even after draining the system.
Make sure there is a fire extinguisher near the unit.
1.2.7. Personal protective equipment
When using and maintaining units, it is necessary to provide for the use of personal
protective equipment such as:
Clothing: People who perform maintenance or work on the system must wear clothing that
does not leave parts of the body uncovered, because during maintenance it is possible to come
into contact with hot or sharp surfaces. Avoid clothing that can cling to or be sucked in by the
airflow.
Safety shoes with non-slip soles, especially in environments where the floor is slippery.
Gloves: Protective gloves must be worn during cleaning and maintenance interventions.
Mask and goggles: Goggles and a respiratory protective mask should be used during cleaning
operations.
