• Metals (some metals) can cause loss of chlorine and stain your pool. Have your local pool professional check for
metals and recommend methods of removal.
• Chloramines should not be present in pool water. When organic materials combine with free chlorine,
chloramines are formed. This ties up the free chlorine in your pool and does not allow the chlorine in your pool
to disinfect. Chloramines also cloud pool water and burn the eyes. Shock to remove chloramines at the initial
startup of the pool.
• Super Chlorination burns out the organic material that has combined with chlorine which frees the chlorine for
sanitizing.SuperChlorinationisaccomplishedbyraisingthechlorinelevelquicklyanddramatically.Tosuper
chlorinatethepoolusingtheJandy®AquaPure®Eichlorinegeneratingdevice,set the chlorine production to
100%andthensetthepumpandthecelltorunfor24hours.
• Shocking (Superoxidation)isalsoameansofburningouttheorganicmaterialthathascombinedwithchlorine.
This method involves the manual addition of chemicals to quickly raise the level of chlorine. When the chlorine
level is quickly raised to 5 - 15 ppm the pool water is said to have been shocked.
NOTE Oninitialstartupofapool,itisbesttoshockusinganalternatesource,i.e.,useashocktreatment
availableatyourlocalpoolsupplier.
CAUTION
NeverusedryacidtoadjustpHinaridgeographicareaswithexcessiveevaporationandminimaldilutionofpool
waterwithfreshwater.Abuildupofby-productscandamagetheelectrolyticcell.
• ThepH condition resulting from the operation of a salt water chlorination system is close to neutral. However,
other factors usually cause the pH of the pool water to rise. Therefore, the pH in a pool chlorinated by a salt water
systemtendstostabilizeatapproximately7.6.IfthepoolpHrisesabove7.6haveapoolprofessionaltesttosee
if other factors such as high calcium hardness or total alkalinity are the cause and then balance accordingly.
• Total Dissolved Solids (TDS). Adding salt to pool water will raise the TDS level. While this does not adversely
affect the pool water chemistry or clarity, the pool water professional testing for TDS must be made aware salt has
beenaddedforthesanitizingsystem.TheindividualperformingtheTDStestwillthensubtractthesalinitylevel
to arrive at the correct TDS level.
• New pool waterinarecentlylledornewlyrenishedpoolmaycontainundesirablematterwhichcouldinterfere
withthesaltwaterchlorinator’sabilitytosanitizeproperly.Makesurethewateristestedbyapoolprofessional
and properly balanced before turning on the chlorinator system.
• Sequestering Agents can be used to compensate for source water which may have unusually high calcium
hardness. High calcium hardness can contribute to scale formation in the pool. Sequestering agents will help
keep minerals in solution and under some conditions can prevent scaling from happening. Consult your pool
professional about the use of a sequestering agent.
4.5 Optimum Pool Water Conditions
In accordance with Association of Pool and Spa Professionals (APSP) standards, we recommend the following water
balanceconditionsbemaintainedonanon-goingbasistoprotectthepoolnishandtheequipmentandtoensure
the pleasing appearance of the water. The Jandy AquaPure Ei is warranted to operate properly only if the following
conditions are met:
Free Chlorine 1.0-3.0ppm.Continuousexposuretolevelsabove3.0ppmmaycause
corrosion of pool metals.
Combined Chlorine (Chloramines) None (Super chlorinate to remove all chloramines).
pH 7.4-7.6(UsemuriaticacidtolowerpHandsodaashtoraisepH).
Chlorine Stabilizer (Cyanuric Acid) 30 - 50 ppm (For outdoor pools only).
Total Alkalinity 80 - 120 ppm
Calcium Hardness 175-400ppm
Metals (Iron, Manganese) None
Nitrates None
Phosphates None
