3C
OPERATION
The Salt & Swim 3C does not have an ON/OFF switch. The unit is designed to be plugged into a protected 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 3C 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. The Salt & Swim 3C automatically scales back to 12 minutes of output per hour (if set higher than 12 minutes)
when the pool water is 10ºC (50ºF) - 15°C (59ºF). This protects the unit as well as prevents possible over-chlorination.
The Salt & Swim 3C stops generating when the pool water temperature drops below 10°C (50ºF). This is usually 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.
Prevent over-chlorination during cold weather:
Check chlorine levels periodically. Most pools require less chlorine
during cold weather and the DAILY CHLORINE OUTPUT should be lowered accordingly.
Maintaining the Salt & Swim 3C System
The replaceable Cell uses the same electronic self cleaning technology as the popular Hayward Turbo Cell. In most
cases this self cleaning action will keep the Cell working at optimum efficiency. In areas where water is hard (high mineral
content) and in pools where the water chemistry has been allowed to get “out of balance,” the Cell may require periodic
cleaning.
Servicing and Cleaning the Salt & Swim 3C Cell
Unplug the Salt & Swim 3C from the protected outlet before attempting to remove the electrolytic Cell. Once removed,
look inside the Cell and inspect for scale formation (light colored crusty or flaky deposits) on the plates and for any debris
which has passed through the filter and caught on the plates. If no deposits are visible, reinstall. If deposits are seen,
use a high pressure garden hose and try to flush the scale off. If this is not successful, use a plastic or wood tool (do
not use metal as this will scratch the coating off the plates) and scrape deposits off of plates. Note that a buildup on the
