Plumbing without pH Clear System
1. TheCellandFlowSensormustbeinstalleddownstreamfromthefilterand
heating devices, but before any Ts in the return line. The Cell may be installed
horizontally or vertically so long as the Cell points in the flow direction (i.e., into
the blue side and out of the clear side).
2. Approximately 15 inches (~380 mm) of pipe length will be needed for
horizontalinstallationsoftheFlowSensorandCell.Verticalinstallationsmay
take less pipe length.
3. HolduptheCellwiththesecondunionstogaugetheproperdistancebefore
threading the second nut and gluing the second slip.

7
4. After letting sufficient drying time for the glue, place the Cell with the o-rings
into the opening between the two ends of the pipe and tighten the unions
making sure that the Cell is installed with the arrow pointing in the flow
direction (i.e., water should enter from the side with the blue cap).
FlowDirection
Installing the Flow Sensor
1. InstalltheFlowSensorjustbeforeorafterthecell.Makesurethatthereisno
valvebetweenthecellandtheflowsensor.TheFlowSensormaybeinstalled
in an angle, but not upside down, because this could cause debris to settle in
the flow sensor body and restrict the paddle movement.
2. Clean and glue the T connector (included) to the pipe, making sure that the
threaded end with the sensor is on the pipe topside.
3. Make sure that the arrow at the top of the Flow Sensor points in the flow
direction and that no glue or pipe cleaner touches the paddle inside the
sensor as it may cause it to jam.
Doublecheckthattheflowsensoroperatesproperlybyreducingtheflowfor
fivesecondsandlookingfortheLowFlowindicatoronthecontrolboxtolight.

Starting Up
Before Adding the Salt
1. Balance the chemicals. See the section titled Understanding the Chemistry
for recommended water balance. Also, remove metals from the water using
a phosphate-free metal remover and test the water to ensure that phosphate
levels are lower than 100ppb (Parts Per Billion). This will ensure that the
transition to the Natural Chlorine Generator system is quick and reliable.
2. New Pools: Wait for 30 days, or longer if specified by the pool builder, for
plaster to cure before adding salt or operating the Natural Chlorine Generator.
3. Biguanide Pools: If installing on a pool using Biguanide sanitizers, all
Biguanides must be removed before system startup.
Adding the Salt
1. Measurethepre-existingsalinityofyourpool.Previouschlorineusemay
cause the salinity reading to be higher due to residual salt in the chlorine.
2. DeterminehowmuchsaltisneededfromtheSalinityDemandTableonthe
following page. This table is based on a salt concentration of 3500 ppm
(approximately1/3%).Moremaybeaddedforlargerpools(e.g.,4000ppm).
3. Keep the circulating pump on.
4. Distributethedeterminedamountofsaltevenlyaroundthepool.Toavoid
clogging the filter or damaging the Control Box and pump, do not add salt
through the skimmer or surge tank. Brush the bottom to help dissolve the salt.
5. The readout on the chlorine generator may fluctuate until the salt is fully dissolved.
Acceptable Salts
GOOD BAD – do NOT to use:
The best salt is an evaporated,
granulated, pool salt.
Iodized salt.
99.9% pure salt.
Salts with more than 1% anti caking
agents (ex. yellow prussiate of soda
orsodiumferrocyanide)−because
they contain iron and will yellow fittings.
These anti caking agents are commonly
found in water softener salts.
Rocksalt−becauseofthedirtmixed
with the rock salt.
Calciumchloride−itisnotasalt.Use
only sodium chloride.

Locate the current salt concentration at the top of the chart (e.g. 1000 ppm).
Thenlocatethesizeofyourpoolontheleft(e.g.100,000liters).Runthese
figures down and across until they meet. That number is the number of Kg of
salt required for your pool.
A D D I N G S A L T
Adding the salt:
Turn the Control Box OFF. Failure to do so will cause the fuse to
blow.
Keep the pump on to circulate the water.
Distribute the required amount of salt evenly around the pool. It
will take 8 hours for the salt to disperse evenly in the water.
Once the salt has fully dissolved, adjust your chlorinator to the desired
setting.

Operating Instructions
Background
PSC-5 is an automatic Natural Chlorine Generator for pool and/or spa
sanitation. The system uses a very low concentration of salt (less than the
concentration in a human teardrop) and converts it into free chlorine that kills
algae and bacteria in your pool. After killing the algae and bacteria, the chlorine
reverts back into salt. This process of purification continues, making the need
toaddextrasanitizingchemicalstoyourpoolvirtuallyunnecessary.ThepH
clearalsoacidwashesthecellautomaticallyandhelpsreducethepHlevelsin
the pool.
Factorssuchassunlight,batherload,debris,chemicalimbalanceandwater
temperature increase the amount of chlorine needed to keep water clean and
safe.
Filtration
Proper filtration is critical for maintaining clean healthy water. It is customarily
required in the pool industry that all the water in the pool pass through the filter
atleastoneandahalf(1½)timesperday(atleasteighthoursonmostpools).
Duringveryheavyuse,thefilterruntimeshouldbeincreased.Ifneeded,thefilter
circulation pump and chlorine generator may be run continuously.
èInadequate filtration: Inadequate filtration reduces water clarity and causes
harder work to the generator.

17
Related Chemistry
Other chemistry levels must be monitored and adjusted because they can
greatly reduce the effectiveness of the chlorine produced by the system. If you
use a good quality pool test kit and follow the simple instructions outlined in this
manual, your Natural Chlorine Generator will help you maintain a sparkling-clean,
trouble-free pool for many years with minimal effort. See the section titled
Understanding the Chemistry for more information.
Basic Operation
The Natural Chlorine Generator produces a pure form of chlorine to sanitize and
oxidize your pool water.
The chlorine residual needs to be maintained at 1 to 3 ppm. This may be tested
using a standard kit or by your local pool store. To obtain the optimal residual
build up of chlorine, the best time to run your filter is in the early morning and after
4pmwhenthereislessUVtodestroythechlorineproduced,leavingchlorinein
the pool to oxidize the unwanted foreign matter.
