a. Removal of the Reverse Osmosis Membrane
Element:
NOTE: It is highly recommended to replace all
O-Rings within the High Pressure Vessel
assembly each time the Reverse Osmosis
Membrane Element is removed or replaced. Each
single High Pressure Vessel assembly contains a
total of 6 O-Rings (4 each Brine O rings and 2
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 C – 2.
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.
