Installation Instructions
General:
Conex Bänninger >BB< MaxiPro training course. All installations must be completed in line with local regulations and by-laws governing the installation, and all applicable health and safety practices must be adhered to.
When using the press tools, care must be taken to ensure hands are kept away from the jaw during the pressing process. Always wear ear and eye protection.
Important :
Select the correct size of tube, fitting and jaw for the job. Ensure the fitting and tube are kept free of any dust or dirt and that the O-ring is undamaged. Check the inner pressing contour of the jaw is free of dirt and debris.
Do not force tube ends together prior to making joints. Joints should only be made on an unstressed pipework assembly.
Remarks:
- A joint is finished after one complete compression cycle of the tool.
- Do not press any >B< MaxiPro fitting more than once.
- Pipework alignment must be completed prior to pressing.
- Do not rotate joints after they have been pressed.
Further Information:
Please refer to the >B< MaxiPro Technical Brochure or visit www.conexbanninger.com for information on:
- Copper tube compatibility.
- Space required for pressing.
- Minimum distance between joints, pressed or brazed.
- Compatible press tools and jaws.
Reference should be made to our Technical Department if clarification is required – [email protected].

- Please refer to >B< MaxiPro – Tube Compatibility Tables, see section 12.10.
- When using refrigerants classified A2L (lower flammability), A2 (flammable) and A3 (higher flammability) additional/specific standards, local rules and regulations, codes of practice and by-laws may be applicable.
NOTE: >B< MaxiPro fittings are NOT suitable for R-717, R-723, R-764, R-744, R-22 refrigerants.
-
Cut the tube to length
- Use a rotary tube cutter.
- Ensure that the tube is cut square.
Check the tube has retained its shape and is damage free.
-
Deburr and remove all external sharp edges
- Deburr the tube both internally and externally.
- Where possible angle the tube downwards to prevent filings entering the tube.
- Use a pencil type deburrer on internal tube edges.
- Make sure the internal and external surfaces of the tube ends are smooth and free from burrs or sharp edges.
-
Use a pencil type deburred on internal edges
-
Clean the tube
- Thoroughly clean the tube end using ROTHENBERGER Rovlies or similar cleaning pad in a rotating action.
- Tube ends must be free from scratches, oxidation, dirt and debris
-
Check for defects
- If deep scratches are visible, cut the tube back to a clean section and prepare the tube end again.
-
Ensure the O-ring is seated
- Check the fitting is the correct size for the tube.
- Check the O-rings are present and correctly seated.
- It is good practice to add a small amount of Conex Bänninger press fitting lubricant to the O-rings to aid tube insertion.
-
Mark insertion depth on tube using depth gauge
-
Insert tube into correct socket in depth gauge.
-
Check window to see the tube is fully inserted.
-
Mark the insertion depth on the tube.
7b. Alternatively insert tube to tube stop and mark -
The tube must be fully inserted into the fitting until it reaches the tube stop.
-
To reduce the risk of dislodging the O-ring rotate the tube (if possible) whileslipping it into the fitting.
-
Mark the insertion depth on the tube.
7b. Check the depth mark -
Remove the tube and align with fitting socket, check that the depth mark is correctly positioned.
-
The insertion depth mark is used as a reference prior to pressing the joint.
-
-
Insert the tube fully into the fitting. Ensure tube is fully inserted prior to pressing
- Insert the tube fully into the fitting up to the tube stop.
- To reduce the risk of dislodging the O-ring rotate the tube (if possible) while slipping it into the fitting.
- Prior to pressing ensure the tube has not moved out from the fitting socket.
- Use the insertion depth mark as a guide.
-
Align jaws squarely on the fitting
- Ensure pipework is correctly aligned prior to pressing.
- Ensure the correct size jaw is inserted into the tool.
- The jaws must be placed squarely on the fitting locating the groove on the bead.
- The bead on the fitting should fit centrally in the groove of the jaw
-
Complete the joint with the approved tool.
-
Depress and hold the button to complete the pressing cycle.
-
Pressing is complete when the jaws are fully closed and the piston retracts.
-
Complete the press cycle once only
DO NOT REPRESS. -
Release the jaws from the pressing.
PRESS ONCE ONLY.
-
-
Mark the completed joint
- Mark the completed joint after pressing.
- This enable joints to be inspected easily before testing and insulating the pipework.
