Refrigerant charging
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.
Make additional charges by adding up pipe length in an order of main pipe (L)
and then selecting the amount of refrigerant corresponding to the remaining (after 30m for the twin connection and after 20m
for the triple/double-twin connections) liquid side pipe diameter and pipe length from the below table.
