System Features
Output Level
The system cleans the water throughout the day. The output level of 0-10 determines how
long the system runs each day. Observe your spa usage patterns and measure the chlorine
level to guide your output level. Keep your output level as low as possible to maintain 1-5
ppm chlorine. By setting output level to 0 the system will stop generating chlorine.
Output Level
0 System off 5-7 Normal use (recommended)
1 Vacation 8-9 High use
2-4 Low output 10 Maximum output (system runs continually)
Limited use or vacation
When the spa is not going to be in use, shock the spa with chlorine to 3-5 ppm while
running the automatic clean cycle. Clean or replace filter(s). Set the output level to 2.
Boost
The Boost feature sets the output level to 10 so that the system runs continuously for 24
hours, overriding the current output level setting. The system returns to its previous output
level once the Boost cycle is complete. Use the Boost function to gradually increase the
chlorine level before or after high spa usage. Spa can be used while in Boost mode.
Status Test
The status test shows you if the system is performing optimally. It reflects a number of
elements that can impact performance, including the salt level, cartridge status (clean/dirty),
and water temperature. The status updates automatically, or you can manually update the
status by activating the status test function on the FreshWater control panel.
Getting Started
Step 1 - Test Fill Water
IMPORTANT: Power must always be OFF when spa is empty.
Before filling your spa, take a sample of your fill water to your local dealer for testing to
determine if your water contains high levels of metals, phosphates, and/or calcium. If high
levels are detected, your dealer can recommend additional products to help bring your fill
water into balance. Starting with contaminated free balanced water, free of contaminants, is
key to the success of clean, long-lasting water with the FreshWater Salt System.

thoroughly after treatment. See Treating for Phosphates on page 8.
Metals - High metal content can impact the performance and start-up process of your
FreshWater Salt system. Iron and manganese should be below 0.5 ppm and copper should

FreshWater Salt System Page 3
English
be below 0.2 ppm. If metals are present in the water, they must be removed before startup
of the FreshWater Salt System. It is strongly recommended to fill your spa using the
FreshWater Clean Screen Pre-Filter. FreshWater Stain and Scale Defense can also be
used following instructions on the bottle.
IMPORTANT: If you use liquid products to remove metals from your spa water, you must
clean your filters and wait 24 hours after treatment before turning the salt system on or
adding any chlorine. See Treating for Metals on page 8.
Step 2 - Fill Spa
NOTE: If you are performing a drain and refill of your spa, it is recommended to
clean filters prior to filling the spa.
If you are changing your current water care program to FreshWater Salt System, you
must drain and rinse your spa and clean your filters before proceeding.
Before adding water, remove plug and insert your salt system cartridge. Using your garden
hose, fill your spa through the filter compartment until the water level reaches 1-inch (2.5
cm) above the highest jet.
NOTE: If your fill water contains high levels of metal (over 0.5 ppm) or calcium (over 300
ppm), use the FreshWater Clean Screen Pre-Filter and/or On The Go as required. Calcium
hardness should be between 25 - 75 ppm.
If you are using a FreshWater Mineral Spa Sanitizer cartridge with the FreshWater Salt
System, insert into the filter compartment per packaging instructions. Silver Ions help
to inhibit bacteria growth and will lower the amount of chlorine needed to keep the water
clean.
Once the spa is filled with water, turn the spa power on (see spa owner’s manual for
specific instructions based on the voltage of your hot tub). Set the temperature to your
desired level (at least 95 degrees Fahrenheit / 35 degrees Celsius). At initial start-up, it is
recommended to set your output level to 0 (system off) until your spa water has reached
temperature and salt has been added.
Check your jet systems by pushing the jets icon on the control panel home screen. When
you’ve confirmed that the jets are fully operational, adjust your diverter valve to middle
position and leave the jets on before adding salt.
NOTE: It’s normal for the water care icon on the control panel and diagnostic logo light (if
equipped) to flash during this step if you choose not to turn your salt system off.
Step 3 - Add Salt (Target 1,750 ppm)
To find the correct water capacity of your spa model, check the chart in your spa owner’s
manual.
Make sure spa jets are on before adding salt. To avoid over salting the water, start out by
adding half the recommended amount of salt (Reference Table 1), using the cup provided
with your FreshWater Spa Salt. Pour the salt into the filter compartment, 1 cup at a time,
with the jets running. Allow five minutes for the salt to dissolve.
Use FreshWater Salt Test Strips to verify the salt level is around 1,750 ppm. Continue to
add salt, one cup at a time, as needed to reach the target level. Be careful to not exceed
the maximum recommended level of 2000 ppm.

Page 4 FreshWater Salt System
English
Note: For initial start-up process, the
FreshWater system status dial should
be "green" when proper salt level has
been reached.
Step 4 - Balance Water
Test your water using a FreshWater
5-Way Test Strip (Reference Table
2). Review pH and alkalinity levels to
determine if your water is within the
salt system’s parameters and adjust
as needed. Make note of the calcium
hardness level as this will be addressed
in step 6. Refer to your spa owner’s
manual for detailed instructions on how
to bring pH and alkalinity levels into
balance. Once the water has
been balanced, retest the
water using the 5-Way Test
Strip. Repeat the process until
the water is balanced.
Step 5 - Sanitize Fill
Water
With all jets on and the diverter
valves turned to the middle
position, add chlorine to the
filter compartment (refer to the
product label for instructions). Run jets for 5 minutes and measure the chlorine with a new
FreshWater 5-Way Test Strip. During the start-up process, your initial target chlorine level
is 5 ppm. If your level is less than 5 ppm repeat the chlorination process. Wait 5 minutes
then test again. Repeat until an initial target level of 5 ppm is reached.
NOTE: If using liquid chlorine - DO NOT USE "splash free” or scented bleach of any kind.
NOTE: It is very important that you shock the spa water with chlorine at start-up.
Skipping this step can prevent the system from establishing a chlorine residual.
Shock is a process of adding doses of a quick-dissolving chlorine to oxidize non-filterable
organic waste and to remove chloramines and bromamines.
Step 6 - Soften Water
NOTE:Include this step if you did not use a calcium remover during the fill process
(in Step 2).
Hard water can damage your hot tub equipment and may hinder the effectiveness of the
salt system, so it's important to make sure your water is soft. Your target calcium level is 50
ppm. Use the following guidelines if your calcium hardness is over 75 ppm:

• 75-150 ppm - Use the FreshWater Vanishing Act pillow provided in your start up kit
(refer to owner’s manual for instructions).
• 150-300 ppm - Use the FreshWater Vanishing Act XL™ or an On The Go portable
water softener (available at your local dealer).
• Over 300 ppm - Use an On The Go portable water softener (used during fill process).
After 24 hours, test spa water with a FreshWater 5-Way Test Strip. If calcium hardness level
still reads above 75 ppm, repeat the process until you get close to 50 ppm target. Discard
FreshWater Vanishing Act pillow in your normal trash after recommended amount of time
and before continuing to next step.
Step 7 - Set Salt System Output Level and Monitor
NOTE: The following is typically performed on Day 2 of start-up
Access the water care menu on your control panel. Set salt system output to the
recommended level indicated in Table 3.
To change the Output Level, one of the three screens below on your spa's control panel will
be displayed.
Output level 0=system off, 10=maximum output
Using a FreshWater 5-Way Test Strip, check the water to ensure a residual chlorine level
of a minimum of 3 ppm has been maintained over the past 24 hours. If the chlorine level
has dropped below 3 ppm, repeat the chlorination process to achieve 5 ppm and press the
Boost button. Check the chlorine level again in 24 hours, and continue the chlorination and
Boost process each day until the salt system can independently maintain the target 3 ppm
chlorine residual. Over the next few days, continue to test your water using a FreshWater
5-Way Test Strip and adjust the salt system output level as needed.
IMPORTANT: The salt system cleans the water
before it produces a chlorine residual that is visible
on a test strip. If there is not a measurable amount
of chlorine in the spa water after 24 hours, this is
an indication that the salt system is still cleaning
the water. If there are contaminants in the water, or
you use the spa initially, it may take the salt system
a few days to clean the spa water and keep up
with your chlorine demand. Use Boost to generate
additional chlorine during this process. This is
perfectly normal and does not mean that your
FreshWater Salt System is not working.

Ongoing Maintenance
1. It is recommended to test and balance your spa water before each use.
• The pH level may increase during the first few weeks after start-up. Add
FreshWater pH/ Alkalinity Down if needed. Ensure that pH and alkalinity levels stay
within the OK range.
• Keep total calcium hardness between 25-75 ppm. Use a new FreshWater Vanishing
Act Calcium Remover when calcium hardness is above 75 ppm.
• The recommended target chlorine level is 3 ppm. Adjust the output level up or down
to maintain the target chlorine level. Boost to supplement chlorine generation after
prolonged use. Supplemental chlorine should only be added as required to achieve
3 ppm chlorine target if the spa is set to the maximum output level 10. You can
reduce the chlorine level in the spa water by adding hydrogen peroxide (see High
Chlorine on page 10).
• Phosphates affect chlorine production and levels. Test and maintain phosphate
levels less than 300 ppb.
2. 10-day system check - Test the spa water & confirm output level
You should test your spa water and confirm output level at least once every 10 days.
A system check reminder will appear on your spa control panel.
a. Every 10 days, if you have not adjusted your output level, the water care icon
on the control panel will flash as a reminder to check your spa by testing and
balancing your spa water and confirming your output level. The 10-day timer
will reset any time you adjust your output level. If you do not perform the 10-day
maintenance routine, the system will default to Low Output Mode (level 3 after
15 days and level 1 after 20 days).
b. Test and balance spa water using a FreshWater 5-Way Test Strip. Measure
chlorine, pH, alkalinity, and calcium hardness levels to determine if your water
is in the OK ranges specified for the system. Adjust as needed. Reduce calcium
hardness if necessary to maintain a range between 25-75 ppm by using the
FreshWater Vanishing Act Calcium Remover.
c. Confirm output level. Adjust your output level as needed to maintain a 3 ppm
chlorine target level. Press the Confirm or OK button to clear the 10-day system
check reminder.
3. Replace FreshWater Salt System cartridge
The chlorine-generating cartridge in the system will typically need replacement after
four months of operation. Once your cartridge has been in service for 4 months the
spa will notify you that it may be time to change your cartridge. The cartridge can be
changed at any time.
1. Follow instructions on control panel to replace cartridge.
2. Remove cap.
3. Press button (on top of cartridge) to remove cartridge.
4. Insert new cartridge. Press button on top of cartridge and push into place.
5. Secure cap. Follow instructions on control panel.

FreshWater Salt System Page 7

4. System Test
The system status test shows you if the system is performing optimally. It reflects a number
of elements that can impact performance, including the salt level, cartridge status (clean/
dirty), and water temperature. The status automatically updates. You can manually update
the system status by activating the status test using your control panel. Table 4 lists system
status messages with meaning or action required.
Green - System is optimal.
Yellow OK - System is OK but should be monitored (see Troubleshooting on page 8).
Red LOW - The system needs your attention and is NOT generating chlorine. The
cartridge may be expired, or the salt level may be low (see Troubleshooting on page 8).
Red HIGH - The system needs your attention and is NOT generating chlorine. The salt
level is high (see Troubleshooting on page 9).

4. Phosphate treatment can be performed at any time after start-up if phosphate
levels increase through spa usage.
Treating for Metals
High metal content can cause staining and discolored water. It is important that metals
are removed before starting up the Salt System.
1. Fill the spa with the FreshWater Clean Screen Pre-Filter per instructions.
2. Ensure that there is no ozone unit installed and that the Salt System is turned to zero.
3. If needed, add FreshWater Stain and Scale Defense according to the instructions
on the bottle. You must turn off your Salt System (Output Level 0) for 24 hours and
thoroughly clean your filters before Step 3 of start-up process.
4. Use a new FreshWater Vanishing Act Calcium Remover (following the instructions).
5. DO NOT add chlorine for at least 24 hours.
NOTE: Do not use the spa until metal treatment is complete and chlorine is added.
System Status OK (Yellow)
The system continues to generate chlorine and operate normally when status
reading is yellow. Monitor the following:
• Salt Level. High or low salt level will shift the status reading, high salt
(yellow right) or low salt (yellow left).
• Low water temperature will lower the status reading (yellow left).
• Dirty filter(s) will lower the status reading (yellow left).
• Cartridge wear will lower the status reading (yellow left).
System Status Low (Red Left)
The system status reading can be affected by cartridge age, scale buildup, cold
water, high chlorine, dirty filter(s), or dirty water.

FreshWater Salt System Page 9
English
1. Verify water temperature
The status reading will read lower in cooler water. To get an accurate status
reading, ensure water is above 95° F (35° C).
2. Verify salt level
Use a salt test strip to measure salt level. If the test strip shows salt level is low:
a. Add 1 cup of salt to the water and circulate for five minutes.
b. Retest with a salt test strip, and repeat until salt level reads in the OK
range.
c. Press Test Status button. If System Status still reads low, check for other
conditions noted above.
3. Verify chlorine level
Use a FreshWater 5-Way Test Strip to measure chlorine level. If the test strip
shows the chlorine level is high (above 5 ppm):
a. Add 1 cup (240ml) hydrogen peroxide with jets running. Check chlorine level
after 10 minutes.
b. Retest with a test strip and repeat as needed.
4. Visually inspect and clean filter(s) (refer to spa Owner’s Manual).
5. Check cartridge
a. Press Test Status button to refresh.
b. If the system status message continues to read low, it may be an indication
that it is time to replace the cartridge. Obtain a replacement cartridge, press
the Replace Cartridge button, and follow the instructions.
System Status High (Red Right)
If the status indicator is in the red (on the right), this typically indicates that there is too
much salt in the water.
1. If the status reading is less than halfway in the red, use a salt test strip to measure salt
level. If the test strip shows salt level is high (above 2,000 ppm):
a. Drain 25% of the water from the spa and refill with clean, clear water.
b. Retest with a salt test strip, and repeat until salt level reads in the OK range.
c. Press Test Status button to refresh.
2. If the salt indicator is more than halfway in the upper red section, drain completely and
refill following the Getting Started section on page 2.
Cloudy Water
Cloudy water can be the result of a number of issues.
• High pH. Use a FreshWater 5-Way Test Strip to check spa pH level. Add pH
Down as needed.
• Low chlorine. Use a FreshWater 5-Way Test Strip. If chlorine is low, manually add
chlorine as needed to shock spa to 5 ppm.
• Dirty filter. Check filter(s) and clean as needed (see your spa Owner’s Manual).

English
N o Chlorine Reading
The system cleans spa water differently than manually added chlorine. If there appears to
be no chlorine in the water:
• Check output level. Check 10-day timer. If you are using the spa frequently/
daily or have the Summer Timer on, you may need to increase your output level.
• Shock. If during the initial start-up process, shock daily until a minimum 3 ppm
chlorine residual is being maintained.
• Consult your dealer about changing the internal system output level.
• Cyanuric acid lock. If you add dry chlorine to shock or supplement your water
and your chlorine reading is back to 0 (zero) ppm, it is possibly your salt system
is reacting to your specific water chemistry or metal content and is being inhibited
by the cyanuric acid from dry chlorine. Consult your dealer about switching to
un-stabilized liquid chlorine (sodium hypochlorite) to correct and stabilize your
water chemistry.
• Remove phosphates. Test and manage phosphate levels.
IMPORTANT Shock the spa water with chlorine at start-up. Skipping this step can prevent
the system from establishing a chlorine residual.
If the system is running at the maximum output level and still cannot keep your
chlorine in range, consult your dealer.
High Chlorine
The system will continue to produce chlorine according to the selected output level,
regardless of whether you use your spa or not. If you begin to use your hot tub less
frequently, it is important that you lower the output level.
If the chlorine level is too high:
• Check output level. You may need to decrease the output level to a lower
number.
• Reduce chlorine. Add 1 cup (240ml) hydrogen peroxide with jets running.
Check chlorine level after 10 minutes and repeat as needed.
• Consult your dealer about changing the internal system output level.
Tips
• Calcium Hardness: Use the FreshWater Vanishing Act Calcium Remover to
keep total calcium hardness levels low and minimize the need for antiscalant
or liquid metal control products. An On The Go portable water softener is
recommended for high calcium hardness areas.
• Heavy Use: Initiate a Boost cycle a few hours prior to heavy use. Periodically test
the chlorine and add chlorine as needed.
• MPS Use: Granular Monopersulfate (MPS) can be used in place of chlorine to
establish a sanitizer residual at start-up and for shocking the spa.
Use FreshWater MPS Test Strips to measure MPS levels in the spa water if MPS
is preferred. NOTE: MPS and MPS test strips are sold separately.

FreshWater Salt System Page 11
English
• Metal Treatment: If metals are present, be sure to discuss this with your dealer.
Use FreshWater Clean Screen Pre-filter and/or Vanishing Act Calcium Remover.
If you use FreshWater Stain and Scale Defense, wait 24 hours before adding
chlorine or turning the salt system on. Excessive use of liquid metal or phosphate
antiscalant products will promote high phosphate levels, which can cause scale
and weaken chlorine output.
• Ozone: Ozone is not recommended with the FreshWater Salt System.
• Phosphates: High levels of phosphates (above 300 ppb) may cause reduced
sanitizer output. Ask your local dealer to help you test for and remove phosphates.
• Salt Level: Salt is not reduced during sanitizer production. The salt level is
only reduced by adding additional water to the spa. Using the spa and adding
chemicals may increase the salt level over time.
• Salt Buildup: Periodically hose off your spa, spa steps, and the deck or concrete
surrounding your spa after use to prevent salt buildup that can occur from splash-
out.
• Summer Timer: The Summer Timer mode will decrease the chlorine generation
time of the system. If the Summer Timer is activated, the output level will most
likely need to be increased to compensate. If chlorine level is low, adjust output
level up by one each day until 1-5 ppm is maintained. Add chlorine to compensate.
• Water Changes: The FreshWater Salt System reduces the amount of chemicals
needed to add to your spa water. You can extend the life of your spa water, up to
12 months, with proper water care. Test your water regularly to ensure spa water
is properly balanced and safe.
Important Additional Information
WARNING: Operating the FreshWater Salt System without water flow through the cartridge
can cause a buildup of flammable gas.
WARNING: To reduce the risk of injury, do not permit children to operate this device.
WARNING: Spa usage and higher temperatures may require higher chlorine output to
maintain proper free available chlorine residuals.
WARNING: Maintaining high salt and chlorine levels above recommended range can con-
tribute to corrosion of spa equipment.
IMPORTANT: Check the expiration date of test strips as test results may be inaccurate
if used after that date.
IMPORTANT: When replacing the cartridge, only use FreshWater replacement cartridges
having a label that clearly states that it is a replacement cartridge for the chlorine-generat-
ing system.
Follow all aspects of the local and national electrical code(s) when installing the system.
Maximum spa water usage temperature is 104º F (40º C). Bathing in spa water at maxi-
mum temperature should not exceed 15 minutes.
