Straighten the coiled copper tube.
Unroll the tube: It is difficult to cut the wound tube correctly, which increases the chances of failure.
Cut the tube with the Tube cutter:
1. Position the cutter blade so that it cuts the tube at a perpendicular angle.
2.Turn the tube cutter to the left to cut the tube.
3. Move the pipe cutter slowly.
Precaution:
• The cut surface will be at an angle.
• The cutter cannot be tightened too much.
• The copper tube will be deformed.
Use the reamer to burr off the cut surface of the tube.
1.Keep the tube opening facing down.
2. Take care not to scratch the inner surface of the tube.
Precaution:
• Debris may enter the pipe.
• A gas leak may occur.
Clean the inside of the tube by tapping the end with a screwdriver.
Make sure that all metal debris is outside the pipe by tapping the pipe
while the opening is pointing down.
Precaution:
• Metal debris in the pipe can damage the compressor.
• If debris adheres to the flange region, a gas leak may occur.
Insert the flange nut
Be sure to insert the flange nut before starting to process the flange.
The flange nut will not fit into the copper tube after the flange has been processed.
Attach the tool to make the (rigid) flange to the copper pipe.
1. Make sure that the internal surfaces of the tool for making the flange are clean.
2. Determine the dimensions of the copper pipe according to the flange making tool. Precaution:
The copper tube will slide out while flange processing is in progress.
• The dimensions of the flange vary.
Align the hole punch.
Align the arrow with the line adjacent to the nearest hole.
Align the arrow on the hole punch according to the position indicated on the flange making tool.
• If the dimension of A is small, the contact surface of the flange will be even smaller and a gas leak is likely.
Flange the tube.
Rotate the flange crank slowly and carefully while it clicks and then rotate freely.
Rotate the handle to the left and lift to the top.
Precaution:
• The tube will not be completely flanged.
• The extended part of the tube (the cone-shaped part) will be scratched.
Remove the tool to make the flange and check the flanged surface.
If the crank is not lifted to the top, the flange making tool will scratch the pipe extension part (the cone-shaped part).
Verification list:
• Is the internal surface of the flanged part equal in width and shiny?
• Is the thickness of the flanged part equal?
• Is the flange part of an adequate size?
