Copper Level
Before installing the MineralPURE unit, the copper level should be tested. There may be readings of copper
sulfate in the water from leached copper piping or from a copper based algaecide. Correct the problem by either
locating the copper pipe (usually next to a water heater) and balancing the pH, or eliminating any algaecides
completely. Shock the pool with an extra heavy dose of chlorine to get rid of the algaecides.
If using the Copper/Silver electrode CLE-42 or CLE-44, the table below will allow you to lookup the calculated
silver content in your water based upon measured copper levels.

G.) Starting Up the System
When all of the above steps have been completed, it is time to start up
the system. Open all valves and turn the power on. Check for water

acquainted with the unit, turn the control knob counter-clockwise till
the unit reads “OFF” and read through the section “RC-50 control
box features.
Setting the Control Knob to the Desired Level
Once you have obtained the desired reading, the setting will most likely remain at that value the entire season,
or close to it. The trick is getting the desired reading quickly.
By turning the control knob clockwise, the unit will read a three-digit number. These are actually milliamp
(mA) readouts and go from 005 to 600 in 5 mA increments. If the readout does not go all the way to 600,
chances are the TDS level is not over 300 or so. Do not cause any alarm or add salt to the pool unless you are
not able to obtain the desired ion level (more in this section to follow).
