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

regulaon n. 517/2014 called “F-GAS” (mandatory in the European zone). Among the provisions of this regulaon, imposes on operators working

in installaons operang with greenhouse gases to hold a cercate, issued or recognised by the competent authority, cerfying that they have

passed an examinaon authorising them to carry out such work. In parcular

• Up to 3kg total refrigerant in the appliance: category 2 cercaon.

• 3 kg and more total refrigerant in the appliance: category 1 cercaon.

The gaseous form of R32 refrigerant is heavier than air and if released into the environment, most of it tends to concentrate in poorly venlated

areas. Inhaling it can cause dizziness and sensaons of suocaon and can develop lethal gas if in contact with naked ames or hot objects (see

the refrigerant’s safety data sheet).

Pay aenon to the fact that refrigerant uids can be odourless.
