Additional refrigerant
10. Installation
Refrigerant pipe installation
•
Basic amount of refrigerant within the outdoor unit [lb(kg)]
– Amount of additional refrigerant has to be calculated based on the sum of all liquid pipe length.
•
Amount of additional refrigerant depending on the pipe size (
ⓐ
)
– Amount of additional refrigerant has to be calculated based on the sum of all liquid pipe length.
– For the indoor unit already connected to EEV kit, the additional refrigerant charging is 0.0067lb/ft (0.01kg/m)
regardless of the pipe size.
