IV. Replacement Parts List
A list of common replacement parts is provided below. Contact your
dealer for replacement parts assistance.
V. Membrane Replacement
1. Turn off the system and close the feed water shutoff valve.
2. Disconnect the membrane feed hoses by loosing the fittings be-
tween the end of the hoses and the pressure vessel end caps.
3. Remove the retaining "U" pins from the pressure vessels.
4. Push the old membrane out of the vessel in the direction of the
feed flow
5. Record the serial numbers of the new membranes.
6. Lightly lubricate the brine seals on the new membranes with
clean water.
7. Install the new membranes in the direction of flow with the brine
seal end going in last.
8. Lightly lubricate the end cap internal and external o-rings with
glycerin.
9. Install the end caps and secure them with the "U" pins.
10. Install the membrane feed hoses.
11. Verify that all retaining "U" pins are installed.
12. Follow the start up procedure in section III-D.

Multiply the nominal product flow at 25°C by the temperature correction factor to
determine the flow at various other temperatures.
VI. Appendix
The following tables are intended as a guide to determining the flow
rates for the PWR4011 series RO systems. All flows are in gallons
per minute (GPM).
Nominal flows for systems with a feed water Silt Density Index
less than 3.
Nominal flows for systems with a feed water Silt Density Index
of 3 to less than 5.
