•  It is necessary to operate the machine under a controlled procedure in order to ensure 

that any risk arising from the combustible gas or vapor during the operation is reduced 
to minimum.

•  Requirements for the total weight of filled refrigerant and the area of a room to be 

equipped with an air conditioner (are shown as in the following Tables GG.1 and GG.2)
