Q. What do I need to do when changing membrane type?

A. Contact Phoenix Vessel Technology, advising of make and model of new membrane. We can then provide advice on appropriate adaptors required to convert to the new membrane. We would also recommend an 'O' Ring Seal Kit to overhaul all seals.

Q. Can you provide me with advice on how to fit a Side Port?

A. It is very important to ensure correct alignment when fitting a Side Port. For full instructions please refer to Page 9 and 10 of User Guide Number 3.

Q. I have a leaking Side Port. What should I do?

A. Make sure the vessel is depressured before taking any action. Then remove the Victaulic clamp and slide the rubber seal away from the joint. Ensure that the Side Port and pipework have a clearnance of between 2.5 mm and 3.2 mm on the joint. Ensure the pipework and port line up to 0.75 mm in any direction. If this is correct you will need to remove the port from the pressure as stated in the manual.

With port removed, check condition of the surface for cracks, damage or imperfections and, if any noted, refer to Phoenix Vessel Technology for further instruction.

If no imperfections noted, fit a new 'O' seal and refit the port as per the instructions in the manual.

If you are still experiencing problems, then contact Phoenix Vessel Technology for further assistance.

Q. How should I shim/align side ported vessels correctly?

A. During assembly of a rig it is very important to ensure that the dimension of the gap between the parts of at least 0.75 mm is maintained. This can be done by shimming the saddles or removing material from the base of the saddle. The ports must line up to within 0.75 mm in both directions. This will ensure a leak free and maximum operating performance from your Phoenix Vessel (see TIP No. 9).
