▪ Either if the unit is factory charged with refrigerant or the unit is non-charged,
you might need to charge additional refrigerant, depending on the pipe sizes and
pipe lengths of the system.
▪ ONLY use tools exclusively for the refrigerant type used in the system, this to
ensure pressure resistance and prevent foreign materials from entering into the
system.
▪ Charge the liquid refrigerant as follows:
If
A siphon tube is present

filling siphon attached")
A siphon tube is NOT present
