ACE Salt Water Sanitizing System Page 1
Overview of the ACE System
The ACE salt water sanitizing system automatically generates powerful cleaners
to improve your hot tub ownership experience. The ACE system makes water care
easy, provides better quality water, and with proper care, allows spa water to last
much longer than with traditional water care – up to 12 months*.
*Visit www.hotspring.com/save-water for more information.
The ACE Cell - Installed in the circulation pump filter of your Highlife Collection or
Limelight Collection spa, the ACE cell contains a diamond electrode that generates
active oxygen, chlorine and other cleaners. Depending upon your spa usage, source
water make-up and proper cell maintenance, the average ACE cell life is 2-3 years.
To maximize ACE cell life: clean and inspect the cell a minimum of every 90
days, keep spa water balanced and maintain a calcium hardness level of 50 ppm.
The ACE Cleaning Cycle - The ACE system cleans the water with active oxygen
first, before it creates a measurable amount of chlorine. While the system is cleaning
the spa water, you will not get a chlorine reading on your test strip. If the chlorine
level is at 0, add bottled dichlor or allow the system more time to build and
maintain a chlorine level.
Calcium Hardness - To ensure effectiveness of the ACE system and maximize ACE
cell life, keep the calcium hardness level of the water between 25-75 PPM. There are
two options to reduce hardness:
1. Vanishing Act Calcium Remover. The standard Vanishing Act can remove
up to 100 ppms of calcium hardness from spa water after the hot tub has
been filled, or after the spa has been topped off. The XL version can remove
up to 300 ppm. Follow instructions on the box.
2. On the Go Portable Water Softener (sold separately). The On The Go
portable water softener allows you to fill your spa with softened water at start
up, and when you need to top the spa off. If you live in a region with hard
water we highly recommend the On the Go portable water softener.
Supplemental Water Care Products - To properly maintain your spa water you
will need additional water care products, some of which are included with your ACE
system. The items included are:
• Vanishing Act
®
Calcium Remover
• FreshWater
®
Spa Salt
• ACE Cell Cleaning Bottle
• FreshWater 5-way Test Strips
• FreshWater Salt Test Strips
Sold separately:
• Clean Screen®Pre-Filter
• Freshwater pH/Alkalinity Up and pH/Alkalinity down

• Freshwater Concentrated Chlorinating granules.
• On the Go Portable
®water softener (if needed)
• Vanishing Act™ Calcium Remover XL (if needed)
• Freshwater Cell Cleaner

Spa Owner Responsibilities
Always maintain balanced spa water. Use a test strip to test/adjust water at
start-up and beyond. Ensure that pH and alkalinity levels stay within the OK range.
Keep total hardness between 25-75 ppm. Use the Vanishing Act calcium remover as
needed.
Test for chlorine regularly. Use a test strip. The recommended chlorine level is
between 1 and 5 ppm. Add FreshWater Concentrated Chlorinated Granules to
supplement the system as needed. You can reduce the chlorine level in the spa
water by adding hydrogen peroxide.
Adjust Output level as needed. To maximize cell life, keep the output level set as
low as possible to meet your needs. If your use pattern changes you will need to
adjust the output level up or down accordingly. The boost function or Freshwater
Concentrated Chlorinating Granules can be used on occasions when more chlorine
is needed.
Clean the ACE cell. The cell should be cleaned at a minimum of once every 90
days. High levels of hardness in the water will mean the cell should be cleaned more
frequently.
Keep the filters clean. Dirty filters can impact the ACE systems ability to maintain
spa water. Clean filters every 30 days to ensure optimal ACE system performance.
30-day check-up. Every 30 days test and balance spa water, confirm your output
setting, rinse filters, and shock with FreshWater
®Concentrated Chlorinating
Granules. A 30-day timer will remind you to perform this step.
Getting Started
Fill your Spa
Fill the spa using the CleanScreen
®
pre-filter (with the valve 50% closed at a 45º
angle). Soft water can be used to fill the spa.
If you have hard water, fill the spa using the On the Go portable water softener or
other soft water source. Ensure hardness no lower than 25 ppm by topping the spa
off with a small amount of tap water.
If you are filling with well water or have metal issues see TREATING FOR METALS
in the troubleshooting section for additional instructions.
NOTE: If you are not filling your spa for the first time, clean your filters with Filter
Cleaner or replace with new filters, before refilling spa.
Page 2 ACE Salt Water Sanitizing System

System Start-up
1. Test and balance spa water using a 5-way test strip. Measure pH, Total
Alkalinity, and Hardness levels, to determine if your water is in the "OK" ranges
specified for the ACE system (see table below) and adjust as needed.
ACE System
Parameter
Target Min - ”OK” Range - Max
Salt 1750 ppm 1500 ppm 2000 ppm
Hardness 50 ppm 25 ppm 75 ppm
Alkalinity 80 ppm 40 ppm 120 ppm
pH 7.4 7.2 7.8
Chlorine 3 ppm 1 ppm 5 ppm
2. Reduce Hardness if needed. Using the Vanishing Act calcium remover may
take 24 hours or longer. Rinse the calcium remover before use, and follow
instructions on the box. Continue the start-up process while the calcium remover
is working; be sure to reposition the bag after jets are turned on/off. Ensure that
the calcium level reaches 50 ppm. Additional Vanishing Acts may be required.
3. Treat for metals if needed. See troubleshooting.

4. Add Salt based on your spa model (see table) one cup at a time to the filter
compartment with jets running. Run jets for 5 minutes to allow salt to dissolve.
Verify salt level with salt test strips.
ACE Salt Water Sanitizing System Page 3

5. Add FreshWater® Concentrated Chlorinated Granules as directed on the
bottle to create a chlorine residual of 5 ppm. Allow jets to run for 5 minutes per
jet system, rotating diverter valves.
6. Turn the ACE system ON. Use your spa’s control panel.
7. Enter Output level. Access the Water Care menu. Scroll through Output Levels
(0=system off, 10=maximum output) by pressing the soft button near the word
Output on the Standard Control Panel or press the or on the Wireless
Remote Control Panel. The recommended Output Level at start-up is between 3
and 5 depending on the spa size.
Note: It may take up to 24 hours for the ACE System Status to register in the
green/OK range of the system status bar.
24 Hours Later
Test spa water with a FreshWater 5-way test strip. Adjust alkalinity and pH as
needed. If hardness is above 50 ppm, use additional calcium removers at this
time.
If there is not a measurable amount of chlorine in the spa water after 24 hours,
the ACE system is still cleaning the water. If there are contaminants in the fill
water or if you use the spa heavily initially, it may take the ACE system a few
days to clean the spa water and keep up with your chlorine demand.
You can still enjoy your spa, simply add FreshWater Concentrated Chlorinated
Granules to the water to achieve a chlorine level of 3 ppm. Repeat this as
needed until your test strip shows that the ACE system is sustaining a minimum
of 1 ppm residual of chlorine in the water.
Ongoing Maintenance
Test spa water with a 5-way strip regularly (at least once every A week)
- The pH level may increase during the first few weeks after start-up. Add pH
down if needed.
- Use the Vanishing Act calcium remover to reduce hardness to 50 ppm as needed.
- Adjust output setting to maintain 1-5 ppm chlorine.
Monthly: Test the water, shock & confirm output level
- Ensure water is balanced. Confirm/adjust output setting via the control panel.
- Shock the water with granular chlorine to 5ppm and flush all jet systems.
- Inspect Cell.
Clean the ACE Cell (at least once every 90 days)
- Visually inspect the ACE cell for calcium scale between the plates (if fill water
has hardness over 50ppm inspect cell monthly).
- Clean the cell as needed, or at least once every three months following
instruction on the cell cleaning solution or cell cleaning bottle.

Features & Settings
Output Level:
The ACE system cleans the water throughout the day. The output setting of 0 -10
determines how long the cell runs each day. Observe your usage patterns and
measure the chlorine level before each use to guide your output setting. Adjust
output up or down to increase or decrease output. Keep your setting as low as
possible to maintain 1-5 pm chlorine. Use Boost or add Freshwater Concentrated
Chlorine Granules for occasional high use situations.
Output Settings
0 No output/System off
1 Vacation/low output mode
2-7 Normal use settings (recommended)
8-9 High use settings
10 Maximum system output, equal to Boost (system runs constantly)
ACE Salt Water Sanitizing System Page 5

Turning the ACE System off
By setting Output to 0, the system will stop generating sanitizers. You will need to
manually maintain the sanitizer level using FreshWater Concentrated Chlorinated
Granules if the ACE system is off.
Vacation or limited use
When the spa is not going to be in use, shock the spa by increasing chlorine to 3-5
ppm and then run the automatic clean cycle. Clean or replace filters. Lower Output to
2. For extended vacations, lower Output to 1 for low output mode.
Boost:
The Boost feature activates the ACE cell for 24 hours of consistent operation,
overriding the output setting. The system returns to its previous setting once the
Boost cycle is over. Use the Boost function to gradually increase the chlorine level
prior to a high use situation.
Freshwater Concentrated Chlorine Granules can also be added to create an
immediate chlorine residual to remove bather load and assist the ACE system in
building a sanitizer residual.
30 Day Reminder:
You must check your spa water at least once every 30 days. To remind you, the
green light on the logo light and the ACE water care icon will flash and the status
message will read, Check Water/Confirm Output at the end of each 30-day cycle.
1. Test and balance spa water using a 5-way test strip. Measure chlorine, pH,
Total Alkalinity, and Hardness levels, to determine if your water is in the “OK”
ranges specified for the ACE system. Adjust as needed. Reduce Hardness to 50
ppm using the Vanishing Act calcium remover if needed.
2. Confirm output setting. Access the Water Care menu. To clear the 30 day
reminder:
Standard Control Panel
• Press the Output soft key.
• Reset your Output setting as needed to maintain a 1-5 ppm chlorine residual.

Day 30: Maintenance reminder, reconfirm output level
Day 33: Output setting automatically lowered to 2
Day 40: Output setting automatically lowered to 1 (Vacation/Low Output Mode).
Status Test:
The status test shows you if the ACE is performing optimally. It reflects a number
of elements that can impact performance including the salt level, cell status (clean/
dirty), filter status (clean/dirty), and water temperature. The status automatically
updates every six hours and prior to a Boost. You can manually update system status
by activating the status test using your control panel.
OK: Your cell and water are working together to clean the water.
LOW: Your system needs your attention and is NOT generating cleaners at this time.
Your cell may be dirty, or your salt level may be low. See TROUBLESHOOTING
HIGH: Your system needs your attention and is NOT generating cleaners at this time.
Your salt level is high. See TROUBLESHOOTING

Cell Cleaning
The cell should be cleaned a minimum of every 3 months. A dirty cell requires the
ACE system to work harder than necessary, and can shorten the life of the cell. A
dirty cell can also cause your System Status to register low, (in the yellow) and cause
the system to go off line.
Prevent Cell Damage: NEVER insert anything into the cell or pressure wash it. This
will damage the electrodes.
1. Turn off the power to the spa. Open the spa cover and remove the filter lid.
2. Unscrew gray filter cap and gently pull the cell out of the filter.
3. Inspect the cell for scale by looking between the electrodes.
4. Unscrew the lid to the ACE Cell Cleaner (or create a cleaning solution by fol-
lowing the instruction on the cell cleaning bottle included with the ACE system.)
NOTE: A stronger cleaning solution of 1 part muriatic pool acid and 10 parts
water, or a commercial cell cleaner, can be used if scale is excessive.
5. Remove the lid and place the ACE cell in the solution, ensuring that the bottom
of cell is floating.
6. Soak the cell for 10 minutes or until bubbles stop coming from the cell. If bubbles
are still releasing from the cell after 10 minutes, continue soaking until the cell is
clean and all scale is removed.
7. Rinse cell and inspect for cleaning completion. Repeat as needed.
8. Replace cell into the filter standpipe. Screw on the gray filter cap, replace the
filter lid, and power up the spa. Ensure that the cell is at the bottom of the filter
standpipe by feeling for the pull of the pump’s suction.
Troubleshooting
Treating for Metals:
High metal content can cause staining and discolored water. It’s important that
metals are removed before starting up the ACE system.
1. Fill the spa with the Clean Screen®pre-filter, ensuring that the valve is only 50%
open (45° angle).
2. Ensure that there is no ozone unit installed and that the ACE system is turned off.
3. Add FreshWater Stain & Scale metal control according to the instructions on the
bottle.
4. Place a Vanishing Act Calcium remover over the heater return.
5. DO NOT add oxidizers (chlorine, ozone, ACE) for at least 24 hours.
Flashing On/Ready light and Water Care Icon
The green ON indicator light, in the Hot Spring logo on the front of your spa will
slowly flash when the ACE system requires attention. The water care icon on the
Page 8 ACE Salt Water Sanitizing System

main control panel will also flash as an indication that some action is needed. Access
the ACE system menu to read the System Status Message.
NOTE: You may continue to use your spa as long as the chlorine level on the
FreshWater
®test strip is in the OK range. Add granular chlorine as needed.
System Status Low (Yellow):
The system status reading can be affected by cell age, scale build-up (dirty cell), cold
water, high chlorine, dirty filters, or dirty water.
1. Verify water temperature
a. The status reading will read lower in cooler water. To get an accurate
status reading, ensure water is above 95° F
2. Verify salt level
a. Use a salt test strip to measure salt level. If the test strip shows salt
level is low:
b. Add (1) cup of salt to the water and circulate for 5 minutes.
c. Retest with a salt test strip, and repeat until salt level reads in the OK range.
d. Run a manual status test to refresh. If System Status still reads low,
check for other conditions noted above.
5. Verify chlorine level
a. Use a 5-way test strip to measure chlorine level. If the test strip shows
chlorine level is high (above 5 ppm):
b. Add 1 cup hydrogen peroxide with jets running. Check chlorine level
after 10 minutes.
c. Retest with a test strip and repeat as needed
4. Visually inspect and clean the cell
a. Follow the cell cleaning process to ensure that scale has not
accumulated on the cell.
b. Once the cell has been cleaned, replace the cell in the filter standpipe.
c. Run a manual Status Test to refresh.
4. Visually inspect and clean filters (refer to spa owner’s manual).
5. If the System Status message continues to read low, it may be an indication that
it is time to replace the cell. Call your authorized Hot Spring Dealer for further
instructions.
System Status High (Red):
If the Status indicator is in the red, this typically indicates that there is too much salt
in the water.
1. If the status reading is less than halfway in the red:
a. Use a salt test strip to measure salt level. If the test strip shows salt
level is high:
ACE Salt Water Sanitizing System Page 9

Page 10 ACE Salt Water Sanitizing System
b. Drain 25% of the water from the spa and refill with clean, clear water.
c. Retest with a salt test strip, and repeat until salt level reads in the OK range.
d. Run a manual Status Test to refresh.
5. If the salt indicator is more than halfway in the red part, drain completely and refill
following the Start-up and Refill Procedure.
Cloudy Water:
Cloudy water can be the result of number of issues.
• High pH. Use a 5-way FreshWater® test strip to check spa pH level. Add pH
down as needed.
• Low chlorine. Use a 5-way FreshWater test strip. If chlorine is low, manually
add granular dichlor as needed to shock spa for 24 – 48 hours.
• Dirty filter. Check filters and clean as needed (see your spa’s Owner’s Manual).
No Chlorine Reading:
The ACE system cleans spa water differently than bottled chlorine. Since the water is
cleaned before the chlorine residual is established, only a small chlorine residual is
needed. If there appears to be no chlorine in the water:
• Check Output settings. If you are using the spa heavily, your use level may
require you to increase the Output setting to a higher number.
• Increase Salt Level. Keep the salt level near the high-end of the OK range
(1750 ppm) to ensure maximum chlorine generation.
It is very important that you shock the spa water with FreshWater®Concentrated
Chlorinated Granules at start-up. Skipping this step can prevent the ACE system from
establishing a chlorine residual.
If the ACE system is running at the maximum output setting and still not able to keep
up with your chlorine demands, manually add Chlorine granules.
High Chlorine Level:
The ACE 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 adjust the Output setting down. If the chlorine
level is too high:
• Check Output settings. Check settings. Your Output may require you to
decrease the setting to a lower number.
• Reduce chlorine level. Add 1 cup hydrogen peroxide with jets running.
Check chlorine level after 10 minutes and repeat as needed.
Tips:
• Calcium Hardness: Use the Vanishing Act calcium remover to keep total
hardness levels low and minimize the need for anti-scalant & metal control.
ON THE GO®portable water softeners are recommended for ACE owners in
hard water areas.

ACE Salt Water Sanitizing System Page 11
• Heavy Use. Initiate a Boost a few hours prior. Periodically measure the chlo-
rine and add granular sodium dichlor as need.
• MPS use. Granular MPS (Potassium Peroxymonosulfate) can be used in
place of chlorine granules to establish a sanitizer residual at start-up, and
for shocking the spa at each 30-day check-up. Use FreshWater® MPS test
strips to measure MPS levels in the spa water if MPS is preferred.
• Metal Treatment. If metals are present be sure to discuss this with your
Hot Spring dealer. Use a Vanishing Act and Stain and Scale control for 24
hours before adding oxidizer from granular chlorine, ozone, or turning the
ACE system on. Excessive use of phosphate anti-scalant will promote high
phosphate levels which can cause scale and weaken chlorine output.
• Mixed Oxidants. To clean the water, the ACE salt water sanitizing system
generates a variety of mixed oxidants, in addition to chlorine. The chlorine
reading on the test strip may not be indicative of total oxidizer level.
• Ozone. The ACE system should be capable of maintaining a sufficient
sanitizer level, and adding ozone is not recommended.
• Phosphates. High levels of phosphates (above 300 ppb) may cause
reduced sanitizer output, ask your local Hot Spring ® dealer to help you test
for phosphates.
• Salt level. Salt is not consumed during sanitizer production. The salt level is
only reduced by adding water to the spa. Using the spa and adding chemi-
cals will increase the salt level over time.
• Salt buildup. Periodically hose off your spa 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 will decrease the chlorine generation
time of the ACE system. If the spa’s Summer Timer is activated, the Output
will most likely need to be increased to compensate. If chlorine level is low,
adjust Output up by one each day until 1-5 ppm is maintained. Add granular
chlorine to compensate.
• Water Changes. Because the ACE salt water sanitizing system reduces the
amount of chemicals added to the spa water, it is possible to significantly
extend the life of the water. Test your water regularly to ensure safety.
Important Additional Information
WARNING: Operating ACE without water flow through the cell can cause a build
up 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 contribute to corrosion of pool or spa equipment.
