For the twin connection, the amount of refrigerant required for pipe length 30m has been included in this unit
at the factory while that required for pipe length 20m has been included for the triple/double-twin connections.
No additional charge is required for the first 30m pipe length in the case of the twin connection and for the first
20m in the case of the triple/double-twin connections. The amount of included refrigerant for each model is
listed on NAME PLATE.
