MEMBRANE CHANGING PROCEDURE
PRESSURE VESSEL END PLUG CHANGING PROCEDURE
1)
Remove the product port (if installed) and the high pressure fitting.
2) Remove the two/three M6 bolts.
3) Remove the two/three locking plates (locks)
4) Remove the backing plate
5)
Pull the end plug with the aid of a hand tight inserted product port in one fast pull.
Should the plugs O-ring (PL01) get stuck in the groove of the pressure vessel, it will be more
difficult to pull the plug. If the plug gets stuck, tap it in, apply silicone lubricant to the
vessel’s inner wall and remove it in one fast pull.
6)
Inspect the end plug for hairline cracks or damages on the O-rings and O-ring
grooves.
7)
Pull the membrane on the product pipe out of the pressure vessel or remove both
plugs and push the membrane out (in flow direction!)
8) Insert the new membrane observing the correct direction of the lipped seal ring on the
high pressure entry side of the membrane (lip against flow direction).
9) Clean the product port and end plug threads from remaining Teflon sealant.
10) Apply Teflon sealant to the threads of the product port.
11) Insert the end plug and reassemble all components visa versa starting with (5).
It is important not to over tighten the product port/s to avoid the end plug to crack.
