Troubleshooting - Hayward Salt Swim® 3C Pro User Manual

Cell indicates that there is an unusually high calcium level in the pool (old pool water is usually the cause). If this is not
corrected, you may have to periodically clean the Cell. The simplest way to avoid this is to bring the pool chemistry to the
recommended levels as specified.
Mild Acid Washing: Use only in severe cases where flushing and scraping will not remove the majority of deposits.
To acid wash, unplug the Salt & Swim 3C unit from the protected outlet and unplug the Cell cord from the replaceable
Cell. Remove the Cell from the Vessel by unscrewing the Retaining Nut and gently pulling the Cell from the Vessel. In
a clean plastic container, mix a solution of water to phosphoric or citric acid. ALWAYS ADD ACID TO WATER - NEVER
ADD WATER TO ACID. Be sure to wear rubber gloves and appropriate eye protection. The level of the solution in the
container should just reach the top of the Cell so that the cylindrical electronics compartment is not submerged. The Cell
should soak for a few minutes and then rinse with a high pressure garden hose. If any deposits are still visible, repeat
soaking and rinsing. Replace Cell and inspect again periodically.
Winterizing
The Salt & Swim 3C replaceable Cell will be damaged by freezing water just as your pool plumbing would. In areas of the
country which experience severe or extended periods of freezing temperatures, be sure to drain all water from the pump,
filter, and supply and return lines before any freezing conditions occur. The Control Box and plumbed in Cell Vessel are
capable of withstanding any winter weather and should not be removed.
Spring Start-up
DO NOT turn the Salt & Swim 3C on until the pool water chemistry has been brought to the proper levels. Refer to the
"Water Chemistry" section of this manual for information on how to prepare your pool water for Salt & Swim 3C operation.
Common Problems and Solutions
The Salt & Swim 3C's various LEDs show the operation status as well as alert the user to any problems that may have
occurred. Some indications may require a combination of LEDs to illuminate. To aid in interpreting these indications,
Hayward has created an interactive tool located at Services on our web site www.haywardpool.ca. Use this tool and the
information below to identify and correct problems that may arise.
1. Possible causes of little or no free chlorine residual
- DAILY CHLORINE OUTPUT adjustment setting is too low
- Low stabilizer (Cyanuric Acid)
- Filter pump time too short (8 hours for average size pools, more for large pools)
- Salt level too low (below 2.4 g/l [2400 ppm])
- Salt level too high
- Very warm pools increase chlorine demand--increase Output %, or filter run time
- Cold water below 10°C (50ºF) causes Salt & Swim to stop generating
- Cold water between 10°C (50ºF) - 15°C (59ºF) causes Salt & Swim 3C to reduce output regardless of DAILY CHLORINE OUTPUT
setting
- Excessive scaling on Cell.
- High level of Nitrogen in pool water.
- "Yellow Out" or similar treatment recently used. Some yellow algae treatments will use chlorine at a very high rate and deplete
the residual free chlorine. Manually shock the pool if indicated in the directions on the algae treatment. It still may be a matter of days
before the pool returns to "normal" and chlorine tests will show the desired 1 - 3ppm free chlorine reading.
2. LEDs not on
Depending on current conditions, there should always be at least one LED illuminated when the Salt & Swim 3C is powered. If no
LEDs are on, check to make sure that the linecord is plugged in and that the protected outlet is powered. If no power is detected, the
protection may have to be reset.
3. STANDING BY LED blinking
The Salt & Swim 3C has shut down because the temperature of the pool water is too high (49°C/120
system will not resume operation until the water temperature returns to normal. Note: This condition can sometimes happen if the pool
temperature is already high and the heater is running. The temperature coming out of the heater and into the Cell could possibly be
to shut down the Salt & Swim 3C.
