each Product Water O rings). Ensure that
you have these O-Rings on hand prior
to opening the High Pressure Vessel.
One O-Ring kit is required for each High
Pressure Vessel assembly.
The Pressure Vessel has a side port
configuration, requiring removal of the port
fittings prior to End Plug removal.
Disconnect the High Pressure Hose from the
inlet end of the High Pressure Vessel Assembly.
Membranes are only installed and removed
from the Inlet side of the High Pressure Vessel.
Using a 5/16” Allen wrench remove the 3
each Socket Head Cap Screws from the three-
piece Segment Ring located at the end of the
Pressure Vessel.
Push inward on the End Plug and Remove the
three-piece segment ring.
Remove the Port Retainer.
Remove the High Pressure Port.
Insert all three of the Socket Head Cap Screws
back into the End Plug. These Socket Head
Cap Screws are used as a handle to remove
the End Plug. Grasp one or more of the Socket
Head Cap Screws with a pair of pliers and
pull outward to remove the End Plug. There is
some resistance due to the two Brine O-Rings
exerting friction against the Vessel wall.
After the End Plug is removed, the R.O.
Membrane Element End and Product Water
Tube are exposed within the Vessel.
CAUTION
: At each end of the Reverse
Osmosis Membrane Element is a Product
Water Tube approximately ¾" diameter
by 1” long. The outside diameter surface
of this product water tube is a sealing
surface, which isolates the Product Water
from the Feed Water. The surface of the
Product Water Tube must be scratch free.
Never use pliers or other grabbing tools
on or near the Product Water Tube.
With the End Plug removed from the High
Pressure Vessel, the Reverse Osmosis
Membrane Element is now visible in the
exposed end of the High Pressure Vessel. With
your fingers grasp the Product Water Tube and
pull outward. If resistance is met then cup the
open end of the High Pressure Vessel with one
hand and shake downward to dislodge the
R.O. Membrane Element. Do not drop the R.O.
Membrane onto a hard surface as the Product
Water Tube may be damaged.
Run a rag through the High Pressure Vessel to
remove any biological film or debris from the
High Pressure Vessel.
b. Inspection and O-Ring replacement: Inspect
each End Plug assembly and its High Pressure
Fittings for signs of wear. Inspect the O rings
in the High Pressure Port fittings and replace
them if they show signs of wear.
Remove the 2 Brine O-Rings and one Product
Water O-Ring from all End Plugs removed
from the High Pressure Vessel.
Clean the end plugs with a cloth and sparingly
lubricate 2 new Brine O-Rings and one new
Product Water O-Ring with O-Ring lubricant.
Place them onto the End Plug.
c. Installation/Replacement of the Reverse
Osmosis Membrane Element:
A new HRO Reverse Osmosis Membrane
Element comes from complete with a “U”
cup Brine Seal at one end of the Element. This
Brine Seal must be at the inlet end of the High
Pressure Vessel. Refer to the Cross Sectional
View on page 1-3.
Insert the down stream end (end without a
brine seal) of the Reverse Osmosis Membrane
Element into the upstream inlet end of the
High Pressure Vessel. Slide the Membrane
Element into the High Pressure Vessel, past
the brine seal, until the Membrane Element
product water tube is 4 inches past the end lip
of the High Pressure Vessel.
Insert the End Plug with new attached
O-Rings into the High Pressure Vessel while
aligning the High Pressure Port and Product
Water Port to the respective holes in the High
Pressure Vessel. Continue pushing inward on
the End Plug until it’s exposed end travels just
past the Segment Ring Groove in the Pressure
Vessel. Ensure that the Ports of the End Plug
are aligned with the Port Holes of the High
Pressure Vessel.
Insert the High Pressure Port Fitting with
attached O-Rings into the High Pressure Port.
Replace the Port Retainer.
Clean the threads of the Product Water Port
Nipple and apply three wraps of new Teflon
