4.1. Precautions

For devices that use R410A refrigerant

•Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigera- tion oil applied to the flared sections.

•Use C1220 copper phosphorus for copper and copper alloy seamless pipes, to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses specified in the table below. Make sure the insides of the pipes are clean and do not contain any harmful contaminants such as sulfuric compounds, oxidants, debris, or dust.

Warning:

When installing or moving the air conditioner, use only the specified refriger- ant (R410A) to charge the refrigerant lines. Do not mix it with any other refrig- erant and do not allow air to remain in the lines. Air enclosed in the lines can cause pressure peaks resulting in a rupture and other hazards.

• Do not use pipes thinner than those specified above.

4.2. Connecting pipes (Fig. 4-1)

•When commercially available copper pipes are used, wrap liquid and gas pipes with commercially available insulation materials (heat-resistant to 100 °C, 212 °F or more, thickness of 12 mm, 1/2 inch or more).

•The indoor parts of the drain pipe should be wrapped with polyethylene foam insulation materials (specifi c gravity of 0.03, thickness of 9 mm, 23/64 inch or more).

•Apply thin layer of refrigerant oil to pipe and joint seating surface before tighten- ing fl are nut.

•Use two wrenches to tighten piping connections.

•Use refrigerant piping insulation provided to insulate indoor unit connections. In- sulate carefully.
