Langelier Saturation index Factors

How to Add Salt to the Pool

FOR ALL NEWLY CONSTRUCTED OR RESURFACED PLASTER POOLS: Do not operate the SC-75 with newly poured
or resurfaced pool plaster. Salt is a corrosive element and severe salt damage can occur to your pool. Wait at
least ONE (1) MONTH after construction to allow plaster to cure before adding salt and operating SC-75. Follow the pool
surface manufacturer's guidelines for your specific pool.
FOR NEW VINYL LINER POOLS, contact the manufacturer for recommended guidelines before adding salt and operating SC-75.
1. Check salt level in pool water before adding any salt to pool.
2. Determine the amount of salt from the following charts.
3. Slowly pour in the salt around the outer perimeter of the pool for quick and even distribution.
a. To avoid clogging the filter or damaging pool related equipment and surrounding surfaces, do not add salt through the
skimmer or surge tank.
4. Brush the pool bottom and allow water to circulate for 24 hours to dissolve salt completely.
5. After 24 hours, verify correct salt level reading by checking the LED indicators on the SC-75 Salt Chlorinator and by a
separate reliable test method.
6. Power on the SC-75 Salt Chlorinator and set the Sanitizer Output level to the proper setting to maintain the appropriate
free chlorine levels in the pool water (i.e., within the 2.0 - 4.0 ppm, APSP recommended range).

Pool Water Preparation

Determining Pool Size (liters of water in your pool)

• Rectangular Pools:
Circular Pools:
•
• Oval Pools:
• Sloping Sides:
Never use dry acid (sodium bisulfate) to adjust pH in arid geographic areas with excessive evaporation and
minimal dilution of pool water with fresh water. A buildup of byproducts can damage the SC-75.
