PRESSURE VESSEL DISASSEMBLY
Step 1:
Disconnect plumbing from pressure vessel for disassembly. Remove the pressure vessel from the LW
vertical frame and continue on a workbench.
Step 2:
Remove the six fasteners and cap ring holding each end plug with an Allen wrench. Place a mark on
each end plug to be removed, place a corresponding mark on each end collar. This will ensure proper
orientation during assembly. Refer to Figure 6.2.
Figure 6.1 - Pressure Vessel End Plug Assembly Callout.
Step 3:
Locate the screwdriver slots located on opposite ends of the pressure vessel end collar (Refer to Figure
6.1). Place an appropriate sized slot screwdriver in each slot. Twist both screwdrivers until the end plug
breaks loose from the pressure vessel. The screwdrivers can now be placed between the end plug and
collar. A prying motion on both sides of the end plug with the screwdrivers will quickly remove it. Use
this procedure for both end caps.
Step 4:
Push or pull the membrane element out of the pressure vessel tube.
Step 5:
Note which end of the pressure vessel the brine seal was installed at. The brine seal is a black u-cup
seal on the membrane outer diameter near one end (Refer to Figure 6.3). This is the feed end of the
pressure vessel. When reinstalling the RO membrane the
brine seal must be located at the feed end
of the pressure vessel.
