Operation
The SwimPure Plus
®
is an automatic chlorine generation system for pool or spa sanitation. The
operation requires a low concentration of salt (sodium chloride) in the pool water. These levels are
low enough that it normally will not be tasted. The SwimPure Plus automatically sanitizes your pool
by converting the salt into free chlorine which kills bacteria and algae in the pool. Chlorine will
revert back to sodium chloride after killing bacteria. These reactions will continuously recycle virtu-
ally eliminating the need to add sanitizing chemicals to your pool. The only time you may need to
add more salt to the pool is when water is replenished due to backwashing, draining, or splashing
(not evaporation).
The SwimPure Plus is offered in three models and is designed to handle the purification needs of
most residential swimming pools up to 40,000 gallons (150,000 liters), or the needs of most com-
mercial pools up to 25,000 gallons (95,000 liters). Check local codes for other restrictions. The
actual amount of chlorination required to properly sanitize a pool varies due to bather load, rainfall,
temperature, and the pool's cleanliness.
NOTE: Hayward does not recommend using the SwimPure Plus to generate bromine.
Select the proper model for your pool (installation and mounting requirements are the same for all
models):
W3SWP15 - for pools up to 40,000 gallons
W3SWP9 - for pools up to 25,000 gallons
NOTE: Before installing this product as part of a saline water purification system in a pool or spa
using natural stone for coping or for immediately adjacent patios/decking, a qualified stone instal-
lation specialist should be consulted regarding the appropriate type, installation, sealant (if any) and
maintenance of stone used around a saline pool with electronic chlorine generator in your particular
location and circumstances.
NOTE: The use of dry acid (sodium bisulfate) to adjust pool pH is discouraged especially in arid regions
where pool water is subject to excessive evaporation and is not commonly diluted with fresh water.
Dry acid can cause a buildup of by-products that can damage your chlorinator cell.
