Chlorination; Default Display - Hayward Pro Logic® Operation Manual

Chlorination

When the chlorinator function is enabled (requires a chlorinator cell and P-KIT sold separately), the Pro Logic is
also an automatic chlorine generation system for pool and/or spa sanitization. If enabled (see Configuration Menu),
this operation requires a low concentration of salt (sodium chloride) in the pool/spa water. The Pro Logic auto-
matically converts the salt into free chlorine which kills bacteria and algae in the pool/spa. Chlorine will revert back
to sodium chloride after killing bacteria. These reactions will continuously recycle, virtually eliminating the need to
add sanitizing chemicals to your pool/spa. The only time you may need to add more salt to the pool/spa is when
water is replenished due to backwashing, draining, or splashing (not evaporation).
The Pro Logic 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 commercial 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.
For pools larger than 40,000 gallons, the Pro Logic can control one or more Hayward Aqua Rite chlorinators to
supplement chlorine production.
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 installation 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.

Default Display

Turn power on at the main panel and turn the Pro Logic control power circuit breaker on. The keypad will show
the default display. The default display alternates between the day/time, air and pool (or spa) temperature, pool/
spa sanitizer setting, and salt level. Under certain circumstances, additional displays may be added to the default
menu to inform you about system operation. Refer to the Programming Menu Flowchart on page 7 to view all
possible displays. The Pro Logic will automatically scroll through all of the available default menu displays or you
can press "<" or ">" to manually scroll.
Optional Remote Display/keypad shown--the display keypad on the
main control unit will have a "Service" button in the upper left
corner instead of the "System Off" button.
