Monitoring and Maintenance 

Water Chemistry Parameters 

VERY IMPORTANT NOTE! 

Your 

Lectranator Soft Touch Model ST 48 

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 all local and state 
requirements. Check the expiry date of the test kit as test results may be inaccurate if used after that date. 

 

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. If the 

water is clear but is difficult getting a bromine residual using DPD or test strips, we recommend using an OTO test kit. 

NOTE: During cold-water conditions, below 60ºF, SANITIZER demand is reduced significantly. 

For colder climate regions 

with sustained low or freezing temperatures, contact your local pool professional for proper pool winterizing instructions. 

WARNING: 

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 pH levels fall below the recommended range, SANITIZER is used up quickly and can be damaging to equipment. For pH 

levels higher than the recommended range, SANITIZER becomes less effective and works harder to keep your pool sanitized. 
Improper pH also contributes to the strong smell, red eyes, dry itchy skin and brittle hair conditions associated with “too much 

Chlorine”. 

CALCIUM HARDNESS AND TOTAL ALKALINITY: 

Your 

Lectranator Soft Touch Model ST 48 

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 the chlorine residual to 

last longer by protecting it from the UV degradation of the sun. With low or no Cyanuric acid it is possible for the chlorine to 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 

Lectranator Soft Touch Model ST 48 

works most efficiently with salt levels between 2.8 – 3.2 g/l (2800- 

3200 ppm).  If it falls below 2.8 g/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 

Lectranator Soft Touch Model ST 48 

will now generate Bromine to purify 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. Always use a registered or scheduled source of sodium bromine..  

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 t o the Cell, equipment and cementitious finish. Have your water 
professionally tested periodically according to the Saturation Index or use this chart to determine your water balance.
