Note: Use tools and measuring instruments exclusively for the new refrigerant R410A in case of direct
contact with the refrigerant.
The design pressure for this product is 601psi(4.15MPa).
To avoid accidental mixing of the different refrigerant or different refrigerant oil, the sizes of the charging
connections have been changed. It is necessary to prepare the foll
owing tools before performing installation.
Tool
The pressure of refrigerant R410A is 1.4 times higher than that of conventional refrigerant, impurities such as
moisture, oxide film, and grease affect R410A easily. Be sure to remove any moisture, dust, different refrigerant
or refrigeration oil from the refrigerant cycle. Otherwise, it may lead to explosion, injury, leakage, electric shock
or a fire.
