( Rated performance for refrigerant line length of: 7.5m)
For installation over rated distance, 70g of refrigerant should be added for each meter in Heat pump Model.
For installation over rated distance, 50g of refrigerant should be added for each meter in Cooling only Model.
ex) When installed at a distance of 15m, 525g of refrigerant should be added in Heat pump Model.
(15-7.5) x 70g = 525g
When installed at a distance of 15m, 375g of refrigerant should be added in Cooling only Model.
(15-7.5) x 50g = 375g
