Hayward Pro Logic Operation Manual page 11

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 on the following page to determine how much salt in pounds or (Kgs) should be added to reach the
recommended levels. Use the equations below (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 chlorine
added to the pool over time has ended 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.
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 dissolving process—do not allow salt
to pile up on the bottom of the pool. Run the filter pump for 24 hours with the suction coming from the main drain
(use pool vacuum if there is no main drain) to allow the salt to evenly disperse throughout the pool. The salt display
may take 24 hours to respond to the change in salt concentration.
Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline together. Use the
chart on page 29 to determine how much stabilizer must be added to raise the level to 80 ppm.

The Filter and up to 3 Lights and Aux outputs can be configured to control variable speed pumps.
These settings allow you to select the desired speed of the variable speed pump for each output used.
The speed can be displayed in % or RPM, whichever is selected in the Configuration Menu. When the
Filter output is on, the actual speed of the pump(s) will be dependent on the minimum and maximum
speeds set for that output in the Configuration Menu.
Turn super chlorinate on or off
Super Chlorinate
Off Move to previous/next menu item
This display only appears if the chlorinator function is enabled. If an AQL-CHEM is being used, super
chlorinate will not be available if chemical sensing is enabled and ORP is in Auto Sensing (see AQL-
CHEM manual).
When you have an unusually high bather load, a large amount of rain, a cloudy water condition, or
any other condition that requires a large amount of chlorine to be introduced to the pool, activate the
Pro Logic Super-Chlorinate function. The Pro Logic will turn on the filter pump, set the pool/spa
valves to the correct position, and set the chlorine generator to maximum output. The superchlorinate
function will continue for the programmed number of hours (see Timers/Super Chlorinate Hours
below) overriding the normal filter pump timeclock settings. At the end of the super chlorinate period,
the pool will return to normal operation.
If you manually turn off the filter pump (using the FILTER button on any display/keypad), the super
chlorinate function terminates. When you turn the filter pump back on, super chlorinate will resume
for the balance of the programmed number of hours.

This setting will appear only if the system has been setup for "chlorinator" and "spa only" or "pool
and spa". If an AQL-CHEM is being used, super chlorinate will not be available if chemical sensing is
enabled and ORP is in Auto Sensing (see AQL-CHEM manual). It will determine the chlorinator output
when the system is operating in spa-only mode. The actual amount of chlorine introduced into the
spa is determined by: this setting, the amount of time the pool operates in spa-only mode, the water
temperature, and the amount of salt in the water. If the filter pump is running due to the freeze
protection feature, then the chlorinator will not operate during this time.
Pool Chlorinator Adjust the desired chlorinator output for pool (0,1,2,3...9,10,15,20...95,100%)
60%
Move to previous/next menu item
This setting will appear only if the system has been setup for "pool only" or "pool and spa". If an
AQL-CHEM is being used, super chlorinate will not be available if chemical sensing is enabled and
ORP is in Auto Sensing (see AQL-CHEM manual). It will determine the chlorinator output when the
system is operating in pool-only or spa spillover modes. The actual amount of chlorine introduced
into the pool is determined by: this setting, the amount of time the filter pump is running, the water
temperature, and the amount of salt in the water. If the filter pump is running due to the freeze
protection feature, then the chlorinator will not operate during this time.
