6. Precautions on Refrigerant Leakage
6.1 Inspection and confirmation beforedebugging
(1) The refrigerant of the air conditioner is harmless and nonflammable.
(2)The room for the air conditioner shall have an appropriate space. In case of refrigerant leak, it cannot go beyond the
critical concentration. In addition, necessary measures can be taken.
(3) The critical gas concentration harmless to the human body is 0.3 kg/m3.
(4) Confirm the critical concentration according to the following steps and take corresponding measures.
Calculate the indoor volume (B [m3]) (by the minimum
volume)
Calculate the filling volume of refrigerant (A[kg])
Volume of refrigerant = filling volume of refrigerant before
delivery (see the nameplate) + refilling volume of refrigerant
corresponding to the length of pipe
Calculate the refrigerant concentration:
≤Critical concentration:0.3[Kg/m³]
A[kg]
B[m³]
