RO ELEMENT REMOVAL - continued
6. The RO membrane (2) is now visible and ready for removal.
Figure 6. Membrane Removal/Installation.
CAUTION
Always remove RO membrane in the direction opposite to that of flow. Observe arrows on
pressure vessel. Damage to O-ring may result
7. Remove the RO membrane (2) from the pressure vessel (1).
8. Remove large O-ring (7) from outer groove on end cap (6). Remove small O-ring (8) from inner groove in
end cap (6).
INSPECTION
Inspect the O-rings (3, 7 and 8) for any sign of damage, deterioration, cuts, etc. Replace if unserviceable.
CLEANING AND LUBRICATION
1. Lubricate the O-rings (7, 8, 3) with Dow Corning 111, to facilitate assembly. See Figure 6.
2. Install large O-rings (7) on end caps (6). Install small O-rings (8) inside the end caps (6).
NOTE
Prior to installation, notice the direction of the flow along the seven pressure vessels to help in installation of the
membrane. The water from high-pressure pump enters from the front of the vessel 1 and travels to its rear.
From there, it enters vessel number 2 from the rear and travels back to the front and so on. It follows this zig zag
pattern all the way through vessel 7.
