10.2. Refrigerant additional charge
1. Piping installation by standard piping
• At the time of shipment from the factory, this unit is charged with enough refrigerant for an equivalent pipe length of 20 m.
(Refer the following table)
But when the piping length exceeds 20m, additional charge is required according to the following table.
Example:
CU-J14DBE5
In case of 30m long pipe (one way), the amount of refrigerant to be replenished is: (30 - 20) x 20 = 200g
