Daily Chlorine Output Setting - Hayward Salt & Swim® 3C Owner's Manual

Operation
Salt & Swim 3C does not have an ON/OFF switch . The unit is designed to be plugged into a GFCI
rated outlet at all times. There should be no need to remove power from the Salt & Swim 3C unless
pool components are being serviced or the pool will be closed.
When power is first applied to the Salt & Swim 3C, an initialization routine will run for approximately
30 seconds. During this time, various LEDs will illuminate. This is perfectly normal and does not
require any input from the user. When the routine is finished, the Salt and & Swim will begin
normal operation.
If the water chemical levels are in the recommended range, there are three factors that you can
control which directly contribute to the amount of chlorine the Salt & Swim 3C will generate:
1. filter time each day (hours)
2. the DAILY CHLORINE OUTPUT setting
3. the amount of salt in the pool
The filter pump timer should be set so that all of the water in the pool passes through the filter at
least once each day. For pools with high chlorine demand, the timer may have to be set longer to
generate enough chlorine.

Daily Chlorine Output Setting

You can adjust the amount of chlorine that is generated using the "+" and "-" button on the Salt
& Swim 3C unit. The DAILY CHLORINE OUTPUT LEDs will display the current setting. Push "+" to
increase and "-" to decrease the current setting. Each DAILY CHLORINE OUTPUT LED represents
6 minutes of chlorine generation out of 1 hour. For example, if 5 LEDs are illuminated, the Salt &
Swim 3C unit will generate chlorine for 5 x 6 = 30 minutes out of every hour of operation. During
this time, the GENERATING CHLORINE LED will be lit. The unit will be idle for the remaining 30
minutes at which time the GENERATING CHLORINE LED will turn off and the STANDING BY LED
will illuminate.
To find the optimum setting, start the operation with 5 DAILY CHLORINE OUTPUT LEDs illuminated.
Test the chlorine level every few days and adjust up or down accordingly. It usually takes 2-3
adjustments to find the ideal setting for your pool and after that, it should only take minor, infrequent
adjustments. Because the chlorine demand of the pool increases with temperature, most people
find they have to adjust up at the peak of the summer and down during colder periods. Salt & Swim
3C automatically scales back to 12 minutes of output per hour (if set higher than 12 minutes) when
the pool water is 50º - 60ºF. This protects the unit as well as prevents possible over-chlorination.
Salt & Swim 3C stops generating when the pool water temperature drops below 50ºF. This is usu-
ally not a problem because bacteria and algae stop growing at this temperature. You can override
these automatic low temperature operations by switching to SUPER CHLORINATE for a day.
NOTE: After the ideal DAILY CHLORINE OUTPUT setting has been found, you may need to raise the
setting when the pool water temperature increases significantly, when there is higher than normal
bather load or when the Salt & Swim 3C Cell ages. You may need to lower the setting when the
pool water temperature decreases significantly or there are long periods of inactivity.
