The pool's chemistry must be balanced BEFORE activating the Pro Logic's optional chlorinator function. NOTE: If the pool does not have new water, add metal remover and non-copper based algaecide to the pool, per manufacturer's instructions. This ensures a quick, troublefree transfer to the Pro Logic system. Salt (When using optional chlorinator function ) Salt Level Use the chart below to determine how much salt in pounds or (Kgs) should be added to reach the recommended levels. Use the Pool Sizing Formula on page 4 (measurements are in feet/gallons and meters/liters) if pool size is unknown. The operating salt level is between 2700-3400 PPM (parts per million) with 3200 PPM being optimal. 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 Pro Logic 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.
