Where your system is equipped with flow meters, simply open the concentrate valve to the desired flow
rate and close the recirculation valve until the pressure registers normal operating pressure. Using the
formula:
% Recovery Rate = Flow rate of Permeate (Product Flow)
Flow rate of Pe Flow rate of Waste
Adjust the valves until the appropriate balance is met. Once the new balance has been established
at normal operating pressure, you may wish to lock the valves in position by removing the handles by
loosening the setscrews located on the valve handle.

Changing Pre-filter Cartridges
The pre-filter cartridge should be changed, as a rule of thumb, every 2 months, monthly in heavy use
applications. It is critical that this be done to ensure that pre-treatment cartridge allow necessary flow
and that suspended particulate is removed from the feed water.
To change the cartridge, turn off the system’s power and as a safety precaution, close the water supply
to the unit. Repeat Step 5(1) from the installation instructions above. Thoroughly flush and clean the
filter housings while they are disassembled. Always use Waterite factory cartridges as replacements.
Monitoring your System Performance
Your system will be operating at its peak performance after about 24 hours of operation. You should
develop a daily log to track line pressure, system pressure, feed water TDS, permeate TDS, permeate
flow rate and waste flow rate. This will allow you to see any developing performance trends or alert you
to system changes that will require you to intervene. It will also be helpful for your dealer or Waterite
technical personnel to have this information available to help troubleshoot your system, should it
become necessary. The table provided in the last few pages of this manual (Section 9) will help you
get started.
Fast Flushing your Vectapure™ RSX
You consider ordering your system with the automatic auto flush option, which can be set for
a periodic fast flush automatically.
(Waterite P/N RSXAFSH) This option should be considered for
any application with over 4 grains/gallon of hardness, any measurable iron in the raw water source or
raw water TDS that exceeds 500ppm. This will substantially increase the life of the membrane element.
Cleaning your Membrane Element
As your membrane begins to age, it will gradually lose some output performance. This is normal and
may result in an overall permeate flow loss of 5% after about 1 year. Your membrane(s) may eventually
begin to lose production due to fouling or scaling in its interior. Symptoms of this may be continuously
falling production rates or elevated TDS levels in the product water.
Do not attempt to operate the
system above specified pressures to compensate for output loss.
