40SMC---N

Refrigerant line connection (Flare connnections)

For refrigerant tubes use seamless, insulated refrigeration grade
tube, (Cu DHP type according to ISO1337), degreased and
deoxidized, suitable for operating pressures of at least 4200 kPa
and for burst pressure of at least 20700 kPa.
Under no circumstances must sanitary type copper pipe be used.
N.B.: Gas extra-charge: outdoor unit 38YY060G903, add 450 g.
