Bending Pipes

 

Installing the Refrigerant Piping

Flaring Process

1.  Hold the pipe downward to prevent cuttings from entering the pipe. 
2.  Using an appropriate tube cutter and deburring tool, cut and deburr the refrigerant pipe.
3.  Remove the flare nuts at the stop valve of the outdoor unit and inside the accessory bag of 

the indoor unit, put them onto the refrigerant pipe as shown below then flare the refrigerant 
pipe with a flaring tool. 

4.  When flaring copper tubing, only use flaring tools that utilize an orbiting mandrel and 

clutched handle. These are typically referenced as R410A flaring tools. By using this type of 
flaring tool, the copper tubing is rolled while being pressed, thereby reducing the probability 
of copper flare cracking.

5.  Check if the flare part is spread evenly and there are no cracks. 

1.  Use a refrigerant pipe bending tool to shape refrigerant piping; smaller diameter piping may 

allow for light hand bending, providing minimum diameter of 6 inches. 

2. 

Do not bend the pipes in an angle more than 90°.

3.  When pipes are repeatedly bent or stretched, the material will be prone to damage, which may 

lead to refrigerant leaks. Do not bend or stretch the pipes more than three times. 

4.  Do not bend the pipe while insulated. First, cut the insulation with a sharp cutting tool and 

expose it to the appropriate bend radius, as shown below. After bending the pipe, replace the 
insulation and seal it with pipe wrap tape. 

 

NOTICE

1.  To prevent distortion and breaking of the pipe, bend the pipe with a radius of curvature of 6 

in. (150 mm) or more. Use a tubing bender when forming the copper tubing into a bend.

2.  If the pipe is bent repeatedly at the same place, it will break.
