Gas Charge Page 49

Gas Charge Additional Refrigerant Charge § The amount of additional charge must be determined by the equation with the total length of liquid pipe. § After calculation, the amount of additional charge should be recorded to the reverse side of the outdoor unit control box cover. § Put in liquid state refrigerant from the liquid port to connect the cylinder by using weight scale. Page 50

Gas Charge Additional Refrigerant Charge (R 22) § The equation of additional refrigerant charge Additional Charge Amount = (Ø 15. 88 liquid pipe length x 180 g/m) + (Ø 12. 7 liquid pipe length x 120 g/m) + (Ø 9. 52 liquid pipe length x 80 g/m) + (Ø 6. 35 liquid pipe length x 50 g/m) Page 51

Gas Charge Additional Refrigerant Charge (R 410 A) § The equation of additional refrigerant charge Additional Charge Amount = (Ø 15. 88 liquid pipe length x 180 g/m) + (Ø 12. 7 liquid pipe length x 120 g/m) + (Ø 9. 52 liquid pipe length x 80 g/m) + (Ø 6. 35 liquid pipe length x 50 g/m) Page 52
