Installation Instructions
Health & Safety / Safe Working Practices
• >B<MaxiPro fittings must be installed by an installer who is appropriately trained and qualified to work on air conditioning and refrigeration installations.
• Installers must undergo the >B< MaxiPro training and be certified.
• 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 away from the jaw during the pressing process. Always wear ear and eye protection.
• Use a rotary tube cutter. • Ensure that tube is cut square.
• Check tube has retained its shape
and is damage free.
1. Cut tube to length
• Deburr tube ends both internally and externally.
• Angle tube downwards to prevent filings entering tube.
• Use a pencil type deburrer on internal tube edges.
• Make sure internal and external surfaces of tube ends are smooth and free from burrs or sharp edges.
2. Deburr tube ends
• Thoroughly clean tube ends using Rothenberger Rovlies or similar cleaning pad in a rotating action.
• Tube ends must be free from scratches, oxidation, dirt and debris.
• If deep scratches are still visible, cut tube back to a clean section.
3. Clean tube ends and check for scratches
• Check the fitting is the correct size for the tube.
• Check the O-rings are present and
correctly seated.
• Additional >B< MaxiPro lubrication may be used to aid tube insertion.
4. Check O-ring
• Insert tube into correct socket in depth gauge.
• Check window to see the tube is fully inserted.
• Mark insertion depth on tube.
5A. Mark insertion depth using depth gauge
• The tube must be fully inserted into fitting until it reaches tube stop.
• To reduce risk of dislodging O-ring rotate tube (if possible) while slipping it into fitting.
• Mark insertion depth on the tube.
• Remove tube and align with fitting socket, check that depth mark is correctly positioned.
• The insertion depth mark is used
as a reference prior to pressing joint.
5B. Alternatively mark insertion depth using fitting
x
• Insert tube fully into the fitting up to tube stop.
• To reduce risk of dislodging the O-ring rotate tube (if possible) while slipping it into the fitting.
• Prior to pressing ensure tube has not moved out
from the fitting socket.
• Use insertion depth mark as a guide.
6. Ensure tube is fully inserted prior to pressing
• Ensure pipework aligned prior to pressing.
• Ensure correct size jaw is inserted into tool.
• Jaws must be placed squarely on fitting locating groove on bead.
• Bead should fit centrally in groove of jaw.
7. Ensure correct alignment prior to pressing
• Depress and hold button to complete pressing cycle.
• Pressing completed when jaws are fully closed and piston retracts.
• Complete press cycle once only – do not repress.
• Release jaws from pressing.
8. Press the joint
• Mark the completed joint after pressing.
• This enable joints to be inspected easily before testing and insulating the pipe-work.
9. Mark completed joint
Key Installation Points
• Tube preparation
Time and care must be taken to prepare the tube ends in accordance with the full instructions
Tube ends must be clean and free from scratches, oxidation, dirt and debris
Tube ends must be deburred internally and externally
• Tube marking and insertion
Before inserting the tube, check to see that the o-ring is seated correctly in the fitting
The tube end must be marked with the socket depth by using either the fitting or the >B<MaxiPro depth gauge
• Installation examination prior to pressing
Ensure the pipe-work is correctly aligned and there are no undue stresses pulling on the joint
• Pressing the fitting
Align the jaw correctly, groove on the bead and squarely to the fitting
Check the tube is fully inserted and the depth mark is in the correct position before pressing
Complete one full cycle of the tool – do not repress
• Installation examination after pressing
Check that all joint have been pressed and marked to indicate completion

Due to the reforming of the tube profile when pressed, it is advised that a minimum distance is allowed between each fitting.
Pressing Close to an Existing Brazed Joint
Localised annealing To ensure proper sealing of both the brazed and >B< MaxiPro joint the minimum distances listed in the above table must be maintained between the two fittings. The distances provided are there to ensure the original characteristics of the tube are maintained.

Note: It is important that there is no residual brazing or other foreign debris on the tubing to be inserted into the >B< MaxiPro fitting. The surface condition on the area of press joint should be clean and free from debris and comply with EN 12735-1 and ASTM-B280.

Brazing Caution – Brazing near to >B< MaxiPro joints should be avoided as this may cause the seal to degrade due to heat transfer. The minimum distances must be maintained to ensure the integrity of the joint. Where minimum distances cannot be maintained adequate precautions must be taken:
• Fabricating the brazed section prior to assembly with the press fittings.
• You must then comply with the minimum distances stated in the table relating to localised annealing.
SYSTEM TESTING
>B< MaxiPro
System Testing
• System testing should be carried out in accordance with local regulations, codes of practice and relevant standards.
• Dry oxygen free nitrogen (OFN) should be used for tightness and strength testing as it is inert. Do not use oxygen for pressure testing, under pressure it reacts violently with hydrocarbons (oil and grease) resulting in explosions and fire.
• The maximum test pressure to be identified by the installer. This will be calculated from the system pressure and the test parameters.
• To ensure >B< MaxiPro fittings are tested safely, during the strength pressure and/or tightness test, the pressure should be raised gradually up to the desired test pressure of the system as established by the installer.
• Measure the system pressure and the ambient temperature at the start and finish of the tightness test – a rise in ambient temperature can mask a leak if this is not taken into account. There will be a pressure change of approximately 0.7 bar with a temperature change of 5oC.
• Care must be taken to ensure a >B< MaxiPro joint will not be close enough to the liquid charging point that the temperature of the joint drops below -40°C when breaking a vacuum by liquid charging the system.
Problem Solving Vacuum Evacuation
Vacuum evacuation removes air, moisture, and non-condensable gases prior to system charging.
Failure to achieve a vacuum:
• A leak or moisture in the system (see below).
• Vacuum pump not working correctly.
• Vacuum pump does not have sufficient capacity.
Failure to hold a vacuum:
• A leak in the system or the connections to the system – find all leaks and repair them.
An ultrasonic leak detector can help pinpoint leaks on a system under vacuum.
• Moisture or refrigerant still in the system – continue evacuation.
• No remedial action e.g. cutting out fittings from the system should be taken until a proper fault finding exercise has been completed.
