Page 3 Salt & Swim™ 3C

GENERAL

The Salt & Swim™ 3C is an automatic chlorine generation system for pool sanitation. The operation requires a low
concentration of salt (sodium chloride) in the pool water. The Salt & Swim 3C automatically sanitizes your pool by converting
the salt into free chlorine which kills bacteria and algae in the water. 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.

The Salt & Swim 3C can handle the purification needs of most residential swimming pools up to 30,000 gallons (114,000
liters). This unique low cost chlorine generator uses a replaceable electrolytic Cell (SAS-CELL-CUL) that is designed to
produce 91 kg (200 lbs) of 100% available chlorine over its lifetime (cell sold separately).

Part number: SAS-CUL

Note that the actual amount of chlorination required to properly sanitize a pool varies due to bather load, rainfall, temperature,
and the pool’s cleanliness.

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.

INSTALLATION

Remove power to the pool filter pump before starting this installation. Installation must be performed in accordance with
Local and NEC codes. The Control Box must be mounted a minimum of 3.5 meters (12ft.) horizontal distance (or more, if
local codes require) from the pool, within 2 meters (6.5 ft.) from a protected outlet, and within 4.5 meters (15 ft.) from where
the Cell will be installed. Take care to protect the Cell cap connector pins while handling the Salt & Swim 3C unit during
installation.

Preparing Pool Water

To prepare the pool water for Salt & Swim 3C operation, the pool’s chemistry must be balanced and salt must be added.
This must be done BEFORE activating the Salt & Swim 3C. Some adjustments to your pool chemistry may take several
hours, so start the procedure well before you intend to operate the Salt and Swim 3C.

Page 4 Salt & Swim™ 3C

NOTE: If the pool does not have new water, add 1 liter of metal remover and 1 liter of non-copper based algaecide to the
pool, per manufacturer’s instructions. This ensures a quick, trouble free transfer to the Salt & Swim 3C system.

Salt & Swim 3C Installation

Follow the step by step instructions located on the Installation Quick Start Guide. Refer to the following sections for more
detailed information.

Mounting the Salt & Swim 3C Control Box

The Salt & Swim 3C is contained in a raintight enclosure that is suitable for outdoor mounting. The Control Box must be
mounted a minimum of 3.5 meters (12 ft.) horizontal distance (or more, if local codes require) from the pool, within 2 meters
from a protected outlet, and within 4.5 meters (15 ft.) from where the Cell is installed.

The Control Box is designed to mount vertically on a flat surface with the cables facing downward. Because the enclosure
also acts as a heat sink (disperses heat from inside the box), it is important not to block the four sides of the Control Box.
Do not mount Salt & Swim 3C inside a panel or tightly enclosed area.

Before securing the Control Box to the intended location, make sure that the power cord will reach the protected outlet and
that the Cell cable will reach the location where the Cell Vessel will be installed. Use the included Mounting Template to
position the fasteners to the mounting surface. Refer to the diagram below.

Plumbing

The Cell Vessel is designed to install in either 50 mm or 63 mm (1½” or 2”) PVC pool plumbing. The Cell Vessel must be
installed on a 25 cm (10 in) run of straight pipe at the end of the return piping just before the water returns to the pool. All pool
equipment should be upstream from the Cell Vessel. It must be located within 4.5 meters (15 ft.) of where the Control Box is
mounted. Also, there must be enough clearance to insert and remove the Cell from the Vessel after the Vessel is installed.

Flow Switch Calibration Procedure
IMPORTANT: Before going any further, the pool water must be balanced and salt must be added to your pool. If this has

not already been done, refer to the “Water Chemistry” section of this manual for information on how to prepare your pool
water for Salt & Swim 3C operation.

At start-up, or when a new Cell is installed, the Salt & Swim 3C will run a Flow Switch Calibration procedure to ensure that
the Cell’s flow switch is properly initialized. This will occur just once when a new Cell is installed. After the flow switch is
initialized, the Salt & Swim 3C will not perform this procedure again until the Cell is replaced. The Flow Switch Calibration
procedure will require the user to cycle the pump on and off. Follow the instructions below:

1. Turn the filter pump OFF.

2. Plug the Salt & Swim’s linecord into a protected outlet. Follow Local and National codes.

After being powered on for the first time, the Salt & Swim 3C will run a diagnostic routine which can take up to 30
seconds. During this time, various LEDs will turn on and off. When finished, the Salt & Swim 3C will display a blinking
INADEQUATE WATER FLOW LED and a solid STANDING BY LED. Keep the Salt & Swim 3C powered for the remainder
of this procedure and go to Step 3.

3. Turn the filter pump ON. Make sure that full flow is achieved (no air in the system) and run the pump for at least 15
seconds.

4. Turn the filter pump OFF.

5. The Salt & Swim 3C should now display a solid INADEQUATE WATER FLOW and a solid STANDING BY LED. The Flow
Switch Calibration procedure is complete. You can now turn on your filter pump and begin normal operation.

If the INADEQUATE WATER FLOW LED is still blinking after performing this procedure, refer to the Troubleshooting section
of this manual.

Water Chemistry

The table below summarizes the levels that are recommended by Hayward. The only special requirements for the Salt &
Swim 3C are the salt level and stabilizer. It is important to maintain these levels in order to prevent corrosion or scaling and
to ensure maximum enjoyment of the pool. Test your water periodically. Your authorized Salt & Swim 3C dealer or most pool
stores can provide you with the chemicals and procedures to adjust the water chemistry. Be sure to tell the pool store that
you are using a Salt & Swim 3C chlorine generator.

CHEMICAL IDEAL LEVELS
Salt 2.7 to 3.4 g/l
Free Chlorine 1.0 to 3.0 ppm
pH 7.2 to 7.8
Cyanuric Acid

(Stabilizer)

20 to 30 ppm (25 ppm best)

Add stabilizer only if necessary
Total Alkalinity 80 to 120 ppm
Calcium Hardness 200 to 300 ppm
Metals 0 ppm
Saturation Index -.2 to .2 (0 best)

Saturation index

The saturation index (Si) relates to the calcium and alkalinity in the water and is an indicator of the pool water “balance”.
Your water is properly balanced if the Si is 0 ±.2. If the Si is below -0.2, the water is corrosive and plaster pool walls will
be dissolved into the water. If the Si is above +0.2, scaling and staining will occur. Use the chart below to determine the
saturation index.

Salt Level

Use the chart on page 10 to determine how much salt in Kgs need to be added to reach the recommended levels. Use
the equations below if pool size is unknown.

Gallons

(pool size in feet)

Rectangular

Round

Oval

The ideal salt level is between 2.7 g/l (2700 ppm) - 3.4 g/l (3400 ppm) with 3.2 g/l (3200 ppm) being ideal. If the level is
low, determine the number of M3 in the pool and add salt according to the chart on page 10. A low salt level will reduce
the efficiency of the Salt & Swim 3C and result in low chlorine production. A high salt level can cause the Salt & Swim 3C
to shutdown and may begin to give a salty taste to your pool (generally, the salt will begin to be tasted at a level of about

3.5g/l [3500 ppm] - 4.0 g/l [4000 ppm]). The salt in your pool is constantly recycled and the loss of salt throughout the
swimming season should be small. 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% pure. This is common food quality or water
softener salt and is usually available in 25 kg (55 lbs) bags. It is also acceptable to use water conditioning salt pellets,
however, it will take longer for them to dissolve. Do not use rock salt, salt with yellow prussiate of soda, salt with anti­caking additives, or iodized salt.

How to Add or Remove Salt

For new plaster pools, wait 10-30 days (check with you local pool professional) 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 vac if there is no main drain) to allow the salt to evenly disperse throughout the pool.

The only way to lower the salt concentration is to partially drain the pool and refill with fresh water.

Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline together. Use the chart
on page 10 to determine how much stabilizer must be added to raise the level to 25 ppm maximum (Use stabilizer only if
necessary).
