4. Installing the refrigerant piping
4.1. Precautions for devices that use R410A refrigerant
• Refer to page 2 for precautions not included below on using air conditioners
with R410A refrigerant.
• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
and do not contain any harmful contaminants such as sulfuric compounds,
oxidants, debris, or dust.
Warning:
When installing or relocating, or servicing the air conditioner, use only the
any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other hazards.
mechanical failure or system malfunction or unit breakdown. In the worst case,
this could lead to a serious impediment to securing product safety.
• The thicknesses listed in the table above are based on Japanese standards.
Use pipes with a maximum working pressure of 4.15 MPa [601 PSIG] or
higher according to local standards.
