■ 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 30m.
(Refer to the following table)
But when the piping length exceeds 30m, additional charge is required according to the following table.
Example:
CU-W34BBP5
In case of 50m long pipe (one way), the amount of refrigerant to be replenished is: (50 - 30) x 50 = 1,000g

Attention
•
• •
• Please do not decrease the gas piping size. (It causes the breakdown of the compressor).
•
• •
• The equivalent piping length and the cooling and heating capacity change rate are same as the standard piping specification.
