The R32 is a refrigerant flammable gas at a low speed of combustion.
X-REVO-3619QE model contains a quantity of refrigerant such that, in case of loss, to ensure that the concentration of the gas inside the room does not become
dangerous, the following limits must be respected:
-
For indoor units installed close to the ceiling (Wall, Cassette and Floor Ceiling ceiling installed) the minimum area of the room is 6 m2
- For indoor units installed close to the floor (Console and Floor Ceiling floor installed) the minimum area of the room is of 42 m2
Also make sure that the value calculated below remains lower than or equal to the toxicity limit to ensure that in the event of a loss, gas concentration in the
room does not become dangerous (for R32 the concentration limit is equal to 0.3 kg/m3 ): 0.3 kg/m3

DISPOSAL CONSIDERAZIONS
Waste treatment methods Gene-
ral Information:
Do not discharge into any place where its accumulation could be dangerous. Consult your supplier for specific
recommendations. Do not discharge it in areas where a risk of forming explosive atmospheres with the air exists.
The gas should be disposed of in a suitable burner with flash back arrestor
Disposal methods: Refer to the EIGA code of practice (Doc. 30 "Disposal of gases", downloadable at Http://www.eiga.org) for better
guiding disposal methods
Contact your supplier for the proper disposal of the case. The discharge, treatment or disposal may be subject to
national, state or local regulations
