Refrigerant Piping
Copper Pipe Connection
Do not use contaminated, dented or used copper tubing. Do not use copper tubes with less than 0.8mm
thickness. Remove burns from cut edges of the pipes with remover. Hold the end of the pipe downwards
to prevent metal chips from entering the pipe. Use proper torgue wrench to tight the flare nuts. If the
torque strength is weak, gas leakage may occur. If it is too tight the flare nut may crack and it may be non-
removable. Insulate the piping to prevent capacity losses and water.
Flare Work
Head projection dimension may differ according to type of flare tool. Refer to table below:
Flare section should be uniform or even. Crack on the flare section or burr on the flare edge is not
acceptable. Make new flare tubing again to prevent potential gas leak.
