Re: [Amel Yacht Owners] Quick question on desalator membrane replacement

Porter,

 

Here are the instructions from Great-water.com:

 

1. Remove the nuts on the tube fittings and disconnect the tubing.

2. Un-mount the pressure vessel.

3. Remove the nuts from the end of the Stainless steel rods.

4. Remove the end plugs from the pressure vessel. ** See notes at bottom

5. Remove the old element. The element must always move through the vessel in the direction of flow, from the upstream end (connected to the pump) to the down stream end (connected to the control panel). There is normally an arrow on the vessel to indicate the direction of flow.

6. Prepare to install the new element. Do not unwrap the element until you are ready to install. Keep this clean and handle carefully.

7. It is recommended ( but not always necessary) to change the o-ring seals on the end plug when the element is changed. If changing the O-rings do this now.

8. The membrane element has an upstream end with a black rubber “V” brine seal in a groove. The element must always move through the vessel in the direction of flow, from upstream to down stream. If you look at the shape of the brine seal you will see that it will be damaged if pushed backwards.

9. Install the end plug in the downstream end. Glycerin can be used as a lubricant to help assembly. Do not use any oil based lubricant that may foul the membrane element.

10. Open the element package bag

11. Insert the membrane element into the upstream end so the brine seal also ends up at the upstream end. 12. Carefully install the end plug in the upstream end. 13. Install the Stainless steel rods & tighten the lock nuts.

14. Re-mount the loaded pressure vessel and reconnect the tubing

 

 

With best regards,

 

Mark

Subject: [Amel Yacht Owners] Quick question on desalator membrane replacement

 

 

If someone who has any experience changing membranes could watch this video and give me any quick advice I would be hugely appreciative

The question surrounds which end of the membrane (ie the O ring end on the membrane) corresponds to regarding the fitting end in the Kevlar sleeve and especially to the tube fitting end. The hydrolic end or the Bobbin end?
Very much appreciated!!!!
