Refrigerant Auto Charge (Fd1 [Cooling], Fd2 [Heating])
This function can be used to automatically charge a suitable amount of refrigerant in the system through cycle operation. Use the refrigerant
auto charge function if the refrigerant amount is not correct after the system is serviced, if there is a leak in the piping, etc. (During the instal-
lation procedure, make sure to calculate and add the proper amount of refrigerant.)
Refrigerant charging time can be different depending on the amount necessary. Approximate charge time is about 6.6 minutes per pound.
