1.2 Necessary Tools and Instrument List for Installation

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 following tools before performing installation.
No. Tool
1 Handsaw
2 Phillips Screwdriver
3 Vacuum Pump
4 Refrigerant Gas Hose
5 Megohmmeter
Note: Use tools and measuring instruments exclusively for the new refrigerant R410A in case of direct contact with the
refrigerant.
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.
