❋ ❋ Charge additional refrigerant according to the total length of the pipe .
Each factory charging values are determined according to basic pipe length 15 m .
When extra pipe length are required, additional charging works must be implemented as describes below .
Refrigerant Charging
❋ ❋ Additional charging amount is determined based on liquid pipe specifications .
Outdoor unit of liquid
Additional charging (g)
Additional Charge(g) = (L1-15)*20
Additional Charge(g) = (L2-15)*50
• L1: Total length of liquid pipe Ø 6 . 3 5(m)_Model : TT090TT
• L2: Total length of liquid pipe Ø 9 . 5 2(m)_Model : TT120/140/160TT
NOTE
Ex) Total length of liquid pipe =20 m
Φ 6 . 3 5 = (20m-15m) x 20g/m = 100 g (Model : TT090TT)
Φ 9 . 5 2 = (20m-15m) x 50g/m = 250 g (Model : TT120/140/160TT)
