(Rated performance for refrigerant line length of : 7.5m)
** A, B mean indoor unit higher located than outdoor unit.
C, D mean outdoor unit higher located than indoor unit.
For installation over rated distance, 25g of refrigerant should be added for each meter in Heat pump Model.
ex) When installed at a distance of 15m, 75g of refrigerant should be added in Heat pump Model.
(15 – 7.5) x 25g = 187.5g
