Water Chemistry Parameters - VERY IMPORTANT NOTE! Your Commander III Model JC13 is designed to provide Sanitizer on a
daily basis. We recommend the following water chemistry ranges and periodic checks to monitor your systems efficiency. Always follow
local health requirements. Check the expiry date of the test kit as test results may be inaccurate if used after that date.
Daily Checks:
1.0 – 3.0 PPM(pool)
Free Chlorine:
1.0 – 3.0 PPM(pool)
Or Bromine:
3.0 – 5.0 PPM(spa)
Free Chlorine:
3.0 – 5.0 PPM(spa)
Or Bromine
7.2 – 7.8
pH:
CHLORINE/BROMINE REQUIREMENTS: During Peak Sanitizer Demand (rainy season or heavy bather usage) it may be
necessary to increase your sanitizer level by increasing your Output Level setting and/or pump run time. Conversely, during
Low Sanitizer Demand, you can decrease your Output Level to a lower setting. For extremely Heavy Sanitizer Demand or to
boost your sanitizer levels quickly, you can Boost the system or supplement with a Potassium Monopersulfate based shock.
NOTE: During cold-water conditions, below 15.6°C (60°F), Sanitizer demand is reduced significantly. For colder
climate regions with freezing temperatures, contact your local pool professional for proper pool winterizing instructions.
CAUTION: Excessive chlorine levels can cause corrosion damage to stainless steel rails, ladders, heater heat exchangers, light
faceplates and other metallic equipment. Avoid over saturation of chlorine levels. The output setting must be sufficiently high
to maintain the recommended chlorine residual in the swimming pool/spa water. Provincial and/or municipal regulation must
be followed.
pH: When your pH falls below the accepted range, your Sanitizer is used up very quickly and can be damaging to your
equipment. For pH levels higher than the accepted range, your Sanitizer becomes much less effective and will work harder to
keep your pool sanitized. Improper pH also contributes to the strong smell, red eyes, dry itchy skin and brittle hair conditions
usually associated with "too much Chlorine".
CALCIUM HARDNESS AND TOTAL ALKALINITY: Your Commander III Model JC13 provides 100% pure sodium
hypochlorite and does not affect the calcium hardness or total alkalinity levels. Maintain and balance only as needed.
CYANURIC ACID (STABILIZER/CONDITIONER): This chemical goes by either trade name and allows your chlorine
residual to last longer by protecting it from the UV degradation of the sun. In outdoor pools/spas with low or no Cyanuric acid,
the chlorine being produced will be used up as quickly as it enters the pool. Check and maintain your cyanuric acid levels at
the same time as your salt level, as these tend to deplete at the same rate. Regulations may exist regarding the use of cyanuric
acid; please consult your local authority. NOTE: For Bromine or indoor pools, it is not necessary to add stabilizer.
SALT RESIDUAL: Your Commander III Model JC13 works most efficiently with salt levels between 2.8 – 3.2 gm/l (2800-
3200 ppm). If it falls below 2.8 gm/l (2800 ppm), determine the salt level and adjust according to the SALT REQUIREMENT.
Low salt will cause premature deterioration of the Cell blades. Maintaining high salt levels above recommended range can
contribute to corrosion of pool/spa equipment. Salt levels exceeding the recommended concentration can be reduced by
diluting the pool/spa with fresh water.
BROMINE RESIDUAL: Along with the normal Salt level, add 0.45 kg (1 lb) Sodium Bromide (NaBr) per 7500 L (2000
gallons) of water. Your Commander III Model JC13 will now generate Bromine to sanitize your pool. Maintain your bromine
level by checking your salt level. Once your salt falls below the recommended range, we suggest you add 0.45 kg ( 1 lb)
sodium bromide with every 22.5 kg (50 lbs) of salt added. NOTE: Always use a registered or scheduled source of sodium
bromide.
SATURATION INDEX (Si): a formula used to ensure that your total water chemistry does not fall into a scale forming or
corrosive condition. Either condition can cause premature damage to the Cell, equipment and exposed pool/spa surfaces.
Have your water professionally tested periodically according to the Saturation Index or use this chart to determine your water
balance.

Test your water for pH, Calcium Hardness, Total Alkalinity and TDS levels. Use the equivalent Factor in the Si equation.
Si = +0.3, balanced
Si above + 0.3, scaling, staining or cloudy water conditions.
Si below -0.3, corrosive to metals, etches/deteriorates plaster finishes or skin irritating conditions.
DO NOT add pool/spa chemicals directly to the skimmer. This may damage the cell.
