After the installation has been completed, the pool operating parameters should remain the same as before. The indicator light on the
ozonegenerator(andontheelectricalinterlockbox,ifsoequipped)willbeilluminatediftheunitsarefunctioningproperly.
Itisrecommendedthatthepoolbesuper-chlorinatedpriortostartingtheozonesystemtoinsureanyorganicbuilduphasbeenelimi-
nated.
System Running Time
Onresidentialpools,theozonegeneratorshouldoperateforsixtoeighthoursperday.Normally,theozonesystemwillrunwhenever
thepoolltrationsystemisoperating.Sincecommercialpoolandspaltrationsystemsnormallyoperate24hoursaday,theozone
system will run continuously on a commercial pool.
Understanding Your Water
Ifahighconcentrationofanymineral(suchascalciumoriron)existsinthewater,itisnecessarytotreatitbeforestartingtheozone
system.ClearWaterTechsuggestsawatersamplebetakentoyourClearWaterTechdistributorforanalysis.Specicrecommend-
ationswillbemaderelativetotheproduct(s)neededtoremovethesemineralsfromthewater.Note: This should be required only
when the pool is drained and relled.
If the water is clean and clear, the ozone system may be started immediately. If the water is dirty and cloudy, it is recommended that it
bedrainedandtheltersthoroughlycleanedbeforerellingandstartingthesystem.Note: It is not recommended that an in-ground
pool be drained in the winter or after the rst rain of a season. Use a shock treatment instead of draining to avoid the possibil-
ity of severe damage resulting from “oating” the pool out of the ground.
Ozone and Bromine
Ozonehasashort“half-life”,whichmeansitdissipatesveryquickly.Therefore,asmallresidualofanotherdisinfectantmustbe
maintained. We recommend the use of bromine in indoor pools. A bromine residual will act as a buffer when the ozone system is not
operating.Bromineneedstobemaintainedatonly1.0PPM(partspermillion)sothatthetraceamountoftheproductinthewaterwill
notbenoticed.Chlorinewillalsoworkasaresidualoxidizerandmaybeusedeffectivelyinconjunctionwiththeozonesystem(see
belowandchartonfollowingpage).
Ozone and Chlorine
Foroutdoorpools,werecommendtheuseofchlorinetosupplementtheozone.Achlorineresidualwillactasabufferwhentheozone
systemisnotoperating.Chlorineneedstobemaintainedat1.0to2.0PPM(partspermillion-seebelow).Todecidewhichformof
chlorine to use in your pool, refer to the chart on the following page.
Water Preparation
Toproperlypreparethewaterfortheozonesystem,makethefollowingadjustmentsandmaintainthelevelsoutlinedbelow:
 Bromine 1.0PPM
or
 Chlorine 1.0to2.0PPM
 pH 7.2-7.6
 TotalAlkalinity 100-150PPM
 CalciumHardness 200-350PPM
Note: If any unusual reactions are experienced when ozone is introduced to the water (such as abnormal color or odor), please wait a few
days to give the ozone and lter system time to work. If the situation continues, your ClearWater T
ech distributor should be consulted.
Algae
Alwaysmaintaintherecommendedresiduallevelsofbromineorchlorine(atleast1.0PPM)tohelpcontrolalgae.Brushingpoolsides
onceaweekisalsoeffective,asisanyalgaecide.Note: Please consult your ClearWater Tech distributor before using any algaecide.
Shock Treatment
If an unusually high bather load causes cloudiness in the water, it is recommended that a chlorine shock treatment be used
to assist the ozone in cleaning the water. Routine, periodic shocking is recommended to prevent buildup of organic contami-
nants, especially with indoor pools. These treatments are available from your ClearWater Tech distributor. Ask for assistance
in selecting the proper product.
