Purifying Fresh or Brackish Water From a Tank or Well
If the system has been pickled or stored or contains cleaning compounds, use the “New
System Startup” procedure.
1. Fill the tank if necessary. Extremely hard water may cause scale buildup, requiring more
frequent cleaning. Do not use water containing large amounts of heavy metals, such as
mine tailing runoff.
2. Set up the product tubing so that the product is being discarded and it can be sampled.
3. Place the feed and brine hoses into the tank or well with the feed strainer near the bottom
and the brine discharging near the top.
4. Start the feed pump and check for flow by inspecting the brine discharge or checking for
pressure on your pressure gauge. If there is no flow open the pressure relief valve on the
hydraulic intensifier and bleed the air out of the feed pump.
5. Check the product water with your hand held salinity tester. When it is below 750 ppm,
you may divert it into your fresh water container.
6. Watch the feed water level and the pressure gauge carefully. If the water level drops too
far add more water. If the pressure gauge reading rises above 80 psi the dissolved solids
concentration in the remaining feed water has risen too high. Discard this concentrated
brine and refill the tank or well. The remaining concentrated feed can be pumped out by
removing the brine hose from the water source and allowing the brine to be discharged
into a drain.
Shutting Down
1. Make about 3 gallons of water into a bucket. This water will be used to flush the salt wa-
ter out of the system.
Use only unchlorinated water for flushing
2. Install the intake service hose and place it in the bucket. Start the feed pump.
3. Flush for 2

minutes or until the pressure drops on the gauge indicating that the mem-
brane is flooded with fresh water. Stop the feed pump.
4. Disconnect and stow the hoses. Replace the plugs in the hose connections.
You may now leave the system unattended for up to five days without further attention.
We recommend operating the system for longer periods and effecting a fresh water flush ra-
ther than running the machine every day and not flushing the system. Remember that you
need to run the system almost a half an hour to make the flushing water. You may notice that
the system output is higher while charging your batteries as the machine is voltage sensitive.
Always ensure that the battery is fully charged after the system is shut down to extend bat-
tery life.
