Installation Instructions for Pools
The ClearBlue Ionizer system install requires three components that are included in the kit. You will also
need a hacksaw or reciprocating saw, PVC primer and PVC glue that are not included.
System Controller
Clear PVC Tee
Mineral Cell
Install the Tee
The tee is installed by gluing it into your pool PVC plumbing. The ideal spot for it is on the return line,
after the pump, filter, and heater (if applicable). If you have a salt or inline chlorinator installed, the tee
should go before the chlorinator. If you do not have space on the return line for the tee, it can go
anywhere in the plumbing that it fits.
The tee should be oriented such that it looks like a capital T if possible. If it is not possible to install
in this manner, it can be installed in any orientation other than an ‘upside down’ capital T.
Cut plumbing and glue in the tee
1) Turn off the pool pump and let the water drain out of the pipe
2) Cut a 2.5” (63mm) section out of the PVC plumbing using a hacksaw or reciprocating saw
3) Remove any dust and burrs from the pipe
4) Apply PVC primer and glue both to the outside of the pipe and the inside of the tee
5) Slide the tee over the pipe on one side as far as it will go and then other side
6) For each glue joint, hold the tee in place for 30 seconds
7) Let the glue dry for 2 hours before turning on the pump

Page 5
Install the Mineral Cell
Once the PVC glue has dried, you can install the Mineral Cell by threading it into the tee. Teflon tape is
not needed. Tighten the cell until it is hand tight. Orient the bars such that the water will flow between
the two bars (or as close as possible with no leaking). Once the controller is mounted, you will plug the
cell into the controller.
Unplug or turn off the power to the controller before plugging in or unplugging the cell. Otherwise,
you could damage the control board.
Install the System Controller
The system controller can be mounted on a wall, wood post, the side of the above ground pool, or
anywhere else that it can be fastened with screws or Velcro tape. Make sure that the power cable for
the controller reaches the power source and the cable from the cell reaches the controller. The
controller is rated for outdoor use, but it should be protected from rain and out of the direct sunlight for
longest life. Placing the controller in a hut or weatherproof enclosure is recommended.
If you are hard wiring the controller into a 240V panel, you can have an electrician clip off the plug and
wire it per local electrical code. Once you have mounted the controller, you can plug the mineral cell
into the receptacle on the side of the controller.
Check out this installation video for pools: https://youtu.be/SGAK0yD6630
The same controller can be plugged into a 120V wall outlet or wired to a 240V panel.
Make sure that the power cable for the controller reaches the power source and the cable from the
cell reaches the controller.

Page 6
When the cell cable is plugged into the controller and the housing is completely threaded into the
tee with the two electrode bars under water, the ‘Ionizing’ light will illuminate or flash blue. If the
‘Ionizing’ light is flashing red, make sure that the cell is plugged in all the way and the two electrode
bars are completely under water.
If your controller has a standard wall plug, it must be plugged into a GFCI protected outlet.
System Controller Configuration
The System Controller has two main functions: Ion/Action and Large Dose
Ion/Action
The Ion/Action setting is the maintenance setting. It represents a percentage of the maximum output
level and is set according to your pool or hot tub size. For example, an Ion/Action setting of 88 means
the controller is outputting minerals at 88% of maximum output. Use the + and –keys to increase or
decrease the number and reach the desired setting. When the controller is set to Ion/Action, the blue
light above the Ion/Action button will illuminate and the ‘Ionizing’ light will be solid blue.
Large Dose
The Large Dose setting is the ramp-up setting. It represents the number of hours that the controller is
set to maximum output. For example, a Large Dose setting of 88 means the controller will run on ‘full
blast’ for 88 hours. As the hours count down, the number will decrease by one each hour until it gets to
01. After the final hour, the controller will switch automatically to the Ion/Action mode.
Use the + and –keys to increase or decrease the number and reach the desired setting. When the
controller is set to Large Dose, the blue light below the Large Dose button will illuminate and the
‘Ionizing’ light will be flashing blue.
The Large Dose setting should be used when:
1) First filling the pool
2) Refilling in the Spring or throughout the season
3) Copper level has not reached 0.2ppm or dips below 0.2ppm

Page 7
Use the calculations below to calculate the setting for Ion/Action and Large Dose based on your
ClearBlue model and pool or spa volume. The Ion/Action and Large Dose can be set to the same
value.
Use the Large Dose Function as many times as needed until the copper level reaches 0.2ppm.
Set the Ion/Action setting first, then set the Large Dose. The Large Dose timer will count down and
then switch automatically back to the Ion/Action setting.
The setting calculations are guidelines only. You must use a copper test and increase or decrease
the Ion/Action setting as required to ensure the copper level is maintained at 0.2ppm to 0.4ppm.
DO NOT REDUCE CHLORINE/BROMINE CONCENTRATION UNTIL COPPER LEVEL REACHES 0.2PPM
Calculating Pool Volume
The ClearBlue controller settings are based on the volume of water in your pool or hot tub. Please use
the calculations below to determine your water volume.
Pool Type
Calculation (Using Feet & Gallons)
Example
Rectangle
Length x Width x Avg. Depth x 7.5 = Volume (gal)
16 ft x 32 ft x 4 ft deep, 8 ft deep end
16 x 32 x 6 x 7.5 = 23,040 gal
Circle
Diameter x Diameter x Avg Depth x 5.9 = Volume (gal)
24ft round pool x 4ft deep
24 x 24 x 4 x 5.9 = 13,594 gal
Oval
Long Dia. x Short Dia. x Avg Depth x 5.5 = Volume (gal)
18ft x 33ft oval pool x 4ft deep
33 x 18 x 4 x 5.5 = 13,068 gal
Irregular Shape
Length x (Width 1 + Width 2) x 0.45 x Avg Depth x 7.5
= Volume (gal)
16 ft long 5 ft deep kidney pool
16 x (8 + 10) x 0.45 x 5 x 7.5 = 4860 gal
Average Depth

Program Lock (PL)
The Program Lock feature allows you to the lock the controls so that they are not inadvertently changed.
To activate the Program Lock, press and hold the + and –keys simultaneously for 20 seconds or until ‘PL’
is shown on the two-digit number screen. Do the same to remove the Program Lock.
Low TDS Mode (Two Decimals on Number Screen)
If the total dissolved solids (TDS) level of the water is low, the controller will go
into Low TDS Mode which is indicated by the two decimals on the screen coming
on. There is no impact to the performance of the system if it switches into Low
TDS Mode and these two decimals can be ignored. However, it is recommended
to test the TDS and increase if needed according to the levels given on page 9.
Low TDS Mode may be activated when the mineral cell is low. If the decimals appear but the TDS is
in range, check the cell. If the bars are worn down to 0.5” (10mm) or below it is time to change it.

Topside Control Option (Hot Tubs Only)
Topside control found on some hot tubs
Topside Ionizing Indicator
When the mode of the controller is set to “Ion/Action” and the “Ionizing” light is illuminated on the
controller, the area in the center of the topside control will illuminate in blue.
Topside Large Dose Function
Press the center of the logo to engage the “Large Dose” mode for the number of hours programmed on
the controller. When “Large Dose” is active, the area in the center of the topside control will flash in
blue. Once the cycle expires, the controller will go back to “Ion/Action”, the center area will illuminate in
blue and the flashing will stop. To stop the Large Dose mode before the cycle finishes, hold down the
button in the center of the logo for 10 seconds.
Turn Off Ionizing
If the mineral level is too high, or you would like to shut off the ionizing for any other reason, hold down
the button in the center of the logo for 10 seconds or until the blue light goes off.
Turn On Ionizing
If the ionizing function has been turned off, press the button in the center of the logo to turn it back on.
The center of the logo will illuminate in blue to indicate that the system is ionizing.
Topside Cell Connection Indicator
When the mineral cell is unplugged, the electrode bars are not under water, or the cell is worn past its
useful life, the light in the center of the topside control will flash red.
Replacing the Mineral Cell
The mineral cell will last 3 –12 months depending on the size of the pool, the temperature of the water,
the amount and intensity of sun reaching the water, and pool usage. The first cell will always wear down
faster because it is used up quicker to ramp up the minerals.
Unplug or turn off the power to the controller before plugging in or unplugging the cell. Otherwise,
you could damage the control board.
It is important to check the cell regularly and make sure there is still some material left on the bars. If
the bars are worn down to 0.5” (10mm) in length or below, it is time to change the cell. When the cell is
completely used up, the ‘Ionizing’ light will flash red.

Page 10
For a pool, it is recommended to change the cell before the start of the pool season or at least every
6 months. For a hot tub, it is recommended to check the cell every 6 months and remove any scale
that has formed on the electrode bars.
To maximize the life of the mineral cell:
1) Keep the copper level at 0.2ppm
2) Cover the pool when it is not in use
3) Keep the chlorine/bromine level between 0.5ppm to 1ppm
4) Use a chlorine or non-chlorine shock once per week
5) Keep phosphates low
If the mineral cell life is less than 3 months or you are having trouble reaching 0.2ppm copper, even
with multiple Large Dose settings, make sure that the phosphate level of the water is below
200ppb. Phosphates act like fertilizer for algae, so the minerals are used up quicker fighting off
rampant algae growth. Your pool water can be tested for phosphates at your local pool store. There
are several products available that will reduce the phosphate level in your pool.
It is important to change the cell before it is completely used up. This is to ensure that the mineral
levels do not drop off which can lead to green water. Green water is unsafe and requires expensive
treatments to clear. Change the cell when the bars are worn to 0.5” (10mm) in length or below.
Pool and Water Maintenance
For the best results from your mineral pool, it is important to start with clean water, keep water
parameters in range, maintain a low chlorine/bromine residual and oxidize excess organic material
on a regular basis.
Opening your Pool
When you open your ClearBlue mineral pool, you can follow the instructions of your pool builder or pool
store. They may recommend an opening kit with products designed to condition the water and get you
swimming as quickly as possible.
Opening kits sometimes use a 'stain and scale remover' or other type of sequestering agent. We do not
recommend using this type of product because it will remove the ClearBlue minerals and neutralize new
mineral production for up to 6 weeks.
If your mineral cell is more than six months old, it should be replaced when you open your pool.
Filling your Pool
We recommend using a pre-filter that attaches to your garden hose when filling your pool. The pre-filter
removes unwanted metals and sediment from the water, so the water is as pure as possible for your
use. If you live in a rural area and are filling from a well, this is even more important.

Page 11
Metal removers, sequestering agents and some stain removers conflict with ClearBlue. If one of
these products is used, it will remove the ClearBlue minerals and neutralize minerals for up to 6
weeks. Unplug or power off the ClearBlue controller for at least 4 weeks after using these products
to prevent unnecessary wear to the cell.
Water Parameters
For the best results, maintain the water parameters in the following ranges.
Apart from the copper and low level of chlorine, the water parameters below are standard for any
pool or hot tub.
Parameter
Range
Notes
Copper
0.2 –0.4ppm
Once 0.2ppm is reached, test for copper every two weeks
pH
7.2 –7.6
pH out of range will cause the water to feel harsh
Alkalinity
80 –120ppm
Calcium
200 –400ppm
Calcium below 200ppm will cause etching to pool surfaces
and equipment; Calcium above 400ppm can lead to scaling
TDS
500 –2,000ppm
Phosphates
<100ppb
It is critical to keep phosphates low to ensure maximize the
life of the mineral cells and minimize chlorine/bromine usage
Chlorine
0.5 –1ppm
Chlorine should be 1 –3ppm until copper reaches 0.2ppm
Regular Water Maintenance
For your pool water to look, feel and smell the best, it is important to maintain a low level of chlorine or
bromine and oxidize regularly.
We recommend using one 3” chlorine or bromine per week and oxidizing with a chlorine or non-
chlorine shock once per week.
Adding an inline chlorine reservoir to your filtration system is a low-cost way to minimize the
chlorine maintenance. Simply fill the reservoir with chlorine or bromine tablets and set the setting
to 25% of maximum. Check weekly to make sure there are still tablets inside.
Using a non-chlorine shock once per week is a fast and easy way to keep lotions, sunscreens, and
organic material from building up in the water.

Page 12
Closing the Pool
When closing your pool, you can follow the closing instructions from you pool store or pool service. If
they recommend a closing kit, take note if there is a stain and scale or other sequestering product used
as part of the closing. This product is optional and if skipped, the minerals will keep fighting algae and
microorganisms in the water throughout the winter. You will find that the water is cleaner and clearer in
the Spring when you open the pool.
We recommend bringing the system controller indoors for the winter. If there is still life left on the cell,
you can leave it in the tee, but you must wrap up the plug end so that the winter weather does not
corrode it.
Cleaning and Care
System Controller
Clean the controller with a soft cloth dampened with water as needed. Do not use any type of cleaner
on the front control panel or plastic housing.
Mineral Cell
If your water is high in calcium, the electrode bars on the mineral cell may become coated with a white
or blue scale. Check the cell every 6 months and remove the scale with a standard metal file. The surface
of the bars does not have to be polished.
If the bars are too scaled up for the system to release minerals, the ‘Ionizing’ light on the controller
will flash red.

Page 13
Troubleshooting
Problem
Possible Cause
Solution
The ‘Ionizing’ light is flashing red
The cell is not plugged in all the way
Make sure the cell cable is completely
plugged into the controller
The electrodes are not under water
Make sure the electrode bars are
completely under water. An air pocket can
form when the pump is not running, and
the tee is installed upside down.
The cell is worn down past its useful life
Change the mineral cell
There is scale on the electrodes
File the scale off the electrodes with a metal
file
I cannot get my copper level to reach
0.2ppm
You have not used the Large Dose function
Set the controller to Large Dose and set the
number to 99. After 99 hours (about 4
days), test again. If your copper level is
below 0.2ppm, do another 99-hour Large
Dose. Repeat until 0.2ppm copper is
reached
The Ion/Action setting is too low
If you find that the copper level reaches
0.2ppm but then drops off, set your
Ion/Action setting higher to compensate
There is not enough chlorine in the water
The chlorine or bromine should be
maintained at 1-3ppm until the copper level
reaches 0.2ppm. Once the copper level
reaches 0.2ppm, you can reduce the
chlorine/bromine concentration to 0.6-
1ppm
The mineral cell needs to be changed
Check the electrode bars on the mineral
cell. If they are 0.5” (10mm) or shorter, it is
time to change the cell
The phosphate level in the water is too high
Have your water tested for phosphates at a
pool store. If the phosphate level is above
200ppb, use products recommended at the
store to bring it down. If you live in a rural
area, you may need to reduce the
phosphate level on a regular basis
The test kit is expired
Check the expiry date on the test kit and
purchase a new one if it is expired
The test kit instructions are not being
followed
Be sure to read the test kit instructions and
follow them exactly
There is no power to the controller
