6-6-6. Handling of Existing Pipe

When using the existing pipe, carefully check it for the following:

•Wall thickness (within the specified range)

•Scratches and dents

•Water, oil, dirt, or dust in the pipe

•Flare looseness and leakage from welds

•Deterioration of copper pipe and heat insulator

Cautions for using existing pipe

•Do not reuse the flare to prevent gas leak.

Replace it with the supplied flare nut and then process it to a flare.

•Blow nitrogen gas or use an appropriate means to keep the inside of the pipe clean. If discolored oil or much residue is discharged, wash the pipe.

•Check welds, if any, on the pipe for gas leak.

When the pipe corresponds to any of the following, do not use it. Install a new pipe instead.

•The pipe has been open (disconnected from indoor unit or outdoor unit) for a long period.

•The pipe has been connected to an outdoor unit that does not use refrigerant R22, R410A or R407C.

•The existing pipe must have a wall thickness equal to or larger than the following thickness.
