Brazing Chart

Minimum Distance Between Joints
To prevent distortion of the tubing, certain fitting sizes require a minimum distance between crimp joints (refer to Chart 1 below). Failure to provide this minimum distance may result in an improper seal.

Elbows

Elbows cause a pressure drop due to changing direction of the inter- nal fluid. This results in a pressure drop slightly higher than a straight length of ACR tubing. When calculating the total line length for pres- sure drop, the below chart can be used to account for elbows.

Fittings Installation Instructions

For hard or annealed ACR copper tubing

1. Select clean, undamaged copper tube and cut to desired Cut tube end square using a pipe cutter or fine- toothed steel saw.
   

2. Deburr the tube inside diameter using a rounded file or a deburring tool.
   

3. Deburr the tube outside di- ameter using a rounded file or a deburring tool. Radially sand the end of the tube with a very fine grit abrasive hand pad. Clean the tube end of all dirt, oil and grease as well as copper dust and chips from sawing.
   

4. Check the fitting to make sure that the seal is in place, clean and free of contaminants. Only original NIBCO gray HNBR seals are to be used. Use only approved
   

5. Mark the tube with the proper insertion depth using a perma- nent marker as indicated by the Insertion Depth Chart. Improper insertion depth may result in an improper seal.
   

6. Insert the tube into the fitting using a twisting motion to the marked depth. NOTE: End of tubing must contact stop.
   

7. Ensure that the proper pressing jaws are installed in the pressing tool and squeeze jaw arms to open jaw set. Place open jaws around the fitting end and ensure that the jaw is prop- erly aligned with the contour of the fitting. For sizes 1-1/8” OD and above, the jaw has a pipe side and bead side orientation.
   

8. Make sure the tube is inserted to the proper depth in fitting and with the tool at a right angle to the tube, start pressing procedure

WARNING ****

Read press tool operator’s manual and fitting manufacturer’s installation

instructions before using. Failure to follow all instructions may result in extensive property damage and/or serious personal injury. Call the NIBCO Technical Service Department at 1.888.446.4226 if you have any questions or need

NOTE: PressACR fittings can only be installed with NIBCO PressACR jaws. Use of any other jaw will void the product warranty

Not suitable for use with ammonia (R717)

Visit www.NIBCO.com for approved list of refrigerants

Leak Testing: Once all fittings are installed and pressed, the system may be tested for leaks. Testing for leaks should consist of pressurizing the system with nitrogen and using soapy water or tracer gas to detect leaks. Pressurize system to a minimum of 50% of the maximum rated pressure of the system, but no more than 700 PSI. Check the system for leaks and make repairs/replacements where necessary, and verify.

SAE Flare Fittings Installation Instructions

Install Press ACR® Female Flare Connector to a Male Flare Connector by making the flare connection prior to pressing the joint

1. Apply compatible refrigerant lubricating oil to inner and outer surface of flare. To avoid overtightening, do not apply oil to the threads. Hand-tighten nut onto flare.
   

2. Complete joint by applying the specified torque to the nut and flare fittings, as shown in the table below. Always use an open ended wrench and a torque wrench to ensure integrity of fittings. Do not use a pipe wrench. Do not exceed the maximum torque listed below.
   

Flares Tightening Torque (DO NOT OVERTIGHTEN)

WARNING

Read press tool operator’s manual and fitting manufacturer’s installation instructions before using. Failure to follow all instructions may result in extensive property damage and/or serious personal injury. Call the NIBCO Technical Service Department at 1.888.446.4226 if you have any questions or need assistance

Crimp Gauge Instructions

1. After crimping the PressACR fitting, place the Crimp Gauge adjacent to the outside of the bead (copper tube side) where the jaws close. There should be a slight copper deformation in that location. If the gauge is in complete contact with the copper fitting, the crimp has been successful. Each pressed connection on the fitting should be gauged.
   

2. If you are unable to obtain complete contact with the copper fitting or see any kind of gap between the gauge and the fitting at the top of the gauge (arch), the crimp has not been successful.
   
   NIBCO provides the PressACR Crimp Gauge to ensure quality installations.
   

WARNING

Read press tool operator’s manual and fitting manufacturer’s installation instructions before using. Failure to follow all instructions may result in extensive property damage and/or serious personal injury. Call the NIBCO Technical Service Department at 1.888.446.4226 if you have any questions or need assistance.
