The refrigerant charge amount brings limitations for indoor unit installation due to
flammability and toxicity of R32
What is the applicable standard?
Toxicity
Indicated by the capital letter A or B
Indicated by digits 1,2,3
Generic Standard: EN378
Product Standard: IEC60335-2-40
R32 is classified as a Lower Toxicity Refrigerant
Toxicity Limit(R32) = 0,30 kg/m3
For reference Toxicity Limit(R410A) = 0,44 kg/m 3
