Step 3.4 Adding refrigerant
If you use a pipe longer than the length specified in the piping codes and standards, you must add 15 g(for ✴✴18✴✴, ✴✴24HV✴✴) and 40 g (for ✴✴24HS✴✴) of refrigerant
CAUTION
•The remaining air in the Refrigeration cycle, which contains moisture, may cause malfunction on the compressor.
•Always contact the service centre or a professional installation agency for product installation.
Before recharging, check whether the cylinder has a siphon or not. There are two ways to recharge the refrigerant:
