The operating salt level is between 2700-3400 PPM (parts per million) with 3200 PPM being opti-
mal. Before adding any salt, test the salt level. This is especially important for retrofit installation to
older pools where all of the chlorine added to the pool over time is ending up as salt. If the level is
low, determine the number of gallons in the pool and add salt according to the chart below. A low
salt level will reduce the efficiency of the sanitization and result in low chlorine production. A high
salt level can cause the OmniPL to stop chlorinating. The salt in your pool/spa is constantly recycled
and the loss of salt throughout the swimming season should be minimal. This loss is due primarily
to the addition of water because of splashing, backwashing, or draining (because of rain). Salt is
not lost due to evaporation.
Type of Salt to Use
It is important to use only sodium chloride (NaCl) salt that is greater than 99.0% pure. This can be
found at most pool stores in 40-80 lb. bags labeled “for use in swimming pools”. Alternatively, use
common food quality or water softener salt that is at least 99.0% pure. It is also acceptable to use
water conditioning salt pellets, however, it will take longer for them to dissolve. Do not use rock salt,
or salt with more than 1% of yellow prussiate of soda, salt with anti-caking additives, or iodized salt.
How to Add Salt
For new plaster pools, wait 10-14 days before adding salt to allow the plaster to cure. Turn the
circulating pump on and add salt directly into the pool. Brush the salt around to speed up the dis-
solving process—do not allow salt to pile up on the bottom of the pool. Run the filter pump for 24
