THE DESIRED ION LEVEL IN THE SPA/HOT TUB IS 0.15 – 0.20 ppm

    G.) Starting Up the System

When all of the previous steps have been completed, it is time to start up the system.  Open all valves and turn the 

power on.  Check for water leaks and all electrical connections for proper and firm connections.

Remove the 

clear protective sheet from the SPA-1R control unit window. 

      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.  

SETTING THE CONTROL BOX 

To get the spa/hot tub “ionized”, turn the control knob on the 

MineralPURE SPA-1R

 to one of the 11 settings. When 

initially starting, set the unit on MAX to reach desired level quickly.  With the pH in the proper range and all other 
factors ideal, it should take a few hours to get the spa/hot tub fully ionized. This also depends on the size of the 
spa/hot tub. 

There are a lot of factors that can effect the rate the 

MineralPURE

SPA-1R

 will produce the ions (see section in 

Troubleshooting).  In order to get the desired reading of 0.15 - 0.20 quickly, you will need to set the 

SPA-1R

 to its 

maximum current output.  Turn the knob clockwise to MAX to reach this setting. 

Other factors that effect the level of ions are produced are keeping the pH under 7.6; the number of hours the filter runs, 

and the setting of the 

SPA-1R

.  Other factors include water temperature and the amount of algae/bacteria already in 

the water.

As a rule of thumb, it will take about 2-3 hours of run time to get a spa/hot tub of 400 gallons fully "ionized" and to the 

desired level of  0.15 - 0.20.  Double that for an 800 gallon spa/hot tub.

      Using the MineralPURE Ion Test Kit

Included with every 

MineralPURE SPA-1R 

is an Ion Test Kit.  The easy-to-use instructions 

are located on the inside cover of the lid.  Please follow those instructions carefully, as the 
reading you get is most important in how you set the 

MineralPURE

 control knob.  When 

using this test kit, make sure you wait 3 minutes for the test to develop and look 

down

 into 

the tube, not from the 

side

.  There is a reading or color match for 0.15 and one for 0.20 on 

the enclosed chart.  

We recommend a copper-ion level 0.15 - 0.20 ppm. In very hot, 

humid areas, stay closer to 0.20 ppm.

      Testing for Copper-Ions

Keep the 

SPA-1R

 on its highest setting (MAX) if you want to reach these levels the fastest when first starting up the 

system. Once the ideal copper-ion level has been reached, turn down the control knob one setting and test a few hours 
later. If the reading is too high, lower the control knob another setting again and test a few hours later. Once you 
obtain a steady copper-ion level in the proper range, keep the control knob on that setting.  

ALWAYS KEEP THE 

TEST KIT OUT OF DIRECT SUNLIGHT AND STORE IN ROOM TEMPERATURE. TEST THE COPPER 
LEVEL ON A WEEKLY BASIS. 

- The copper-ion level is too low, turn the control knob up to the next setting and retest a few hours later. 
- If the copper-ion level is too high, turn the control knob down to the next setting and retest a few hours later.
