SETUP INSTRUCTIONS
1. Assemble the above-ground-pool (AGP) and its filter pump according to their installation
instructions.
2. Take the Saltwater System and its accessories out of the packaging.
3. Place the Saltwater System in line after the filter pump.
4. Connect the connector hose (2) to the Saltwater System inlet with a hose clamp (3).
5. Go directly to step 6 if your pool is empty. If your above-ground-pool is filled with water,
unscrew the strainer grids from the strainer connectors and insert the black hat-like plugs
into the connectors, before installing the saltwater pool system.
6. Disconnect the water return hose from the filter pump connection and connect it to the
Saltwater System outlet.
7. Connect the connector hose (2) to the filter pump outlet connection with a hose clamp (3).
Tighten securely.
8. Remove the black hat-like plugs that prevent water from flowing out of the pool. Now,
return the strainer grids to the strainer connectors.
IMPORTANT
• The Saltwater System requires a separate filter pump [300~1000 gph
(1136~3785 lph)] to drive the water and function properly.
• The Saltwater System must be installed as the last piece of pool equipment in
the water return line to the pool as displayed below. This location extends the
life of the titanium plates.
• Remove any large debris and particles such as leaves, sand, insects and bugs
from the pool water first.

SALT & POOL WATER VOLUMES
• Which kind of salt to use:
Use only Sodium Chloride Salts
Use only sodium chloride (NaCl) salt that is at least 99.8% pure. It is also acceptable to use
water conditioning salt pellets (the compressed forms of evaporated salt). However, it will take a
longer time for them to dissolve.
Do not use iodized or yellow (yellow prussiate of soda) colored salt.
Salt is added to the pool water and the electrolytic cell uses the salt to create sodium
hypochlorite. The purer the salt the better the performance of the electrolytic cell.
• Optimum Salt Levels
The ideal salt level in the pool water is between 2500-3500 ppm (parts per million). The optimal
level is 3000 ppm.
A too low salt level will reduce the efficiency of the Saltwater System and result in low sodium
hypochlorite production. A high salt level may generate a salty taste to the pool water (this may
occur at a salt level above 3500-4000ppm). Too high salt level may damage the power supply
and cause corrosion to the pool metal fixtures and accessories. The Salt Table page of this
manual shows the correct dosage of salt needed.
• Adding Salt
1. Switch the filter pump on to start the water circulation.
2. Keep the Saltwater System turned off.
3. Determine the amount of salt to be added (see “Salt Table”).
4. Evenly spread the proper amount of salt around the inside perimeter of the pool.
5. Avoid clogging the filter. Do not add salt through the skimmer.
6. Brush the pool bottom to speed up the dissolving process. Do not allow salt to pile up on the
bottom of the pool. Run the filter pump 24 consecutive hours to thoroughly dissolve the salt.
7. After 24 hours and if all the salt is dissolved, turn on the Saltwater System, press button,
code “00” flashing and set the saltwater pool system to desired operating time (see “Operating
Time Table”).
• Removing Salt
If too much salt has been added, the unit will beep and display “Code 92” (see “Alarm Codes”).
You will need to lower the salt concentration. The only way to do so, is to partially drain the pool
and refill it with fresh water. Drain and refill approximately 20% of the pool’s water until the “Code
92” disappears.

INTEX POOLS CYANURIC ACID TABLE
Cyanuric acid is a chemical that reduces the loss of chlorine in water due to ultraviolet
rays. To maintain the pool water clear and clean, and to maximize the performance of
the device, add cyanuric acid to the pool. We recommend that the cyanuric acid level be
maintained at approximately 0.35% of the salt, i.e. 100 Lbs (45 Kgs) salt x 0.35% =
0.35 Lbs (0.16 Kgs) cyanuric acid.

3. Set operating hours for Saltwater system:
With code “00” flashing, press button to set
the desired operating hours. See the “Operating
Time Table” for the required operating hours
related to each pool size. Pressing will
increase the time from 01 to 12 hours
maximum. If you have selected too many hours
keep pressing to repeat the cycle. The built-in
timer will now activate your Saltwater System, at the same time each day, for the number
of hours you have set.
NOTE: The Saltwater System will not operate if the filter pump is not operating. Make
sure to program your filter pump (or start it manually) for operation beginning 5 minutes
before the saltwater system and finishing 15 minutes after the saltwater system.
4. Lock keypad controls:
With the desired hour value showing, press button. A green
“WORKING” indicator on the control panel will light up within a few
seconds to indicate that the saltwater system has started sodium
hypochlorite production, the LED will display the remaining chlorinator
hours until it’s finished. Locking the control buttons into this setting
prevents unauthorized changing of the operating cycle.
NOTE: If you forget to lock the keypad controls, the system will automatically lock it and
start working 10 seconds later.
5. Readjust operating time if necessary:
The operating hours can be re-adjusted if necessary. Press button and the current
programmed time will flash. Repeat steps 3 to 4.
6. Stand-by/power saving mode:
• When the cycle ends, the green “SLEEP” indicator on the control
panel lights up and the LED display flashes “93”. The system is now
in Stand-By mode. After a while, it shuts down and sets itself in a
Power Saving mode. The system will automatically turn itself back on
in 24 hours, starting its daily cycle of sodium hypochlorite production.
• The “SLEEP” indicator stays on, while the system is in the Power
Saving mode. The LED display however, goes blank after 5 minutes.
Press any button ( or ) to view the last LED code.
(1 to 12 hours max per cycle)

MAINTENANCE
IMPORTANT
Unplug the power cord before cleaning your system. Also insert the black hat-like
plugs in the strainer opening to prevent water spillage. After completing all
maintenance tasks, you must plug the power cord back in and remove the plugs.
Titanium Electrode Cleaning
The titanium electrode has a self cleaning function incorporated into the electronic control’s
programming. In most cases this self cleaning action will keep the electrode working at
optimum efficiency. If the pool water is hard (high mineral content) the electrode may require
periodic manual cleaning. To maintain maximum performance, we recommend that you open
and visually inspect the titanium electrode (7) monthly.
The following steps provide instructions on how to clean your cell.
Inspection and cleaning:
1. Switch off the unit, unplug the power cord from the electrical socket.
2. To prevent water from flowing out of the pool, unscrew the strainer grids from the strainer
connectors and insert the hat-like plugs into the strainer connectors.

MAINTENANCE (continued)
3. Disconnect the 2 hoses from the Saltwater System (see drawing 1~3).
4. Unscrew the titanium electrode plug collar, disconnect the plug from the titanium electrode
(7) (see drawing 4).
5. Unscrew the cell nut, remove the titanium electrode from the cell housing (see drawing 5).
6. Place the titanium electrode in a container and pour kitchen grade vinegar into the
container until the titanium electrode is immersed. Soak for 1 hour and then flush with a
high-pressure garden hose (see drawing 6).
7. Reverse steps 3, 4, 5 and 6 to reconnect the electrolytic cell.
The Test Strips can test the “Free Chlorine”, “pH”, “Calcium Hardness” and “Total Alkalinity”
levels at the same time. We recommend that you test the water chemistry weekly, and maintain
the chlorine concentration at 1.0-3.0 ppm.
Directions and Use
1. Dip the entire strip into the water and remove immediately.
2. Hold the strip level for 15 seconds. Do not shake excess water from the strip.
3. Now compare the strip pad to the color chart on the packaging label. If necessary, adjust the
chemical level in the pool water. It is very important, to use the proper technique when
testing the water's chemical level. Read and follow the written strip instructions carefully.
1. Disconnect the power cord from the electrical outlet.
2. After the pool is completely empty, disconnect the Saltwater System from the hoses by
reversing the installation instructions.
3. Air-dry the unit before you store it. This might be a good time to visually inspect and clean
the electrolytic cell.
4. Store the unit and accessories in a dry place. The temperature should be controlled, between
32 degrees Fahrenheit (0 degrees Celsius) and 97 degrees Fahrenheit (36 degrees Celsius).
5. The original package can be used for storage.

POOL MAINTENANCE & CHEMICAL DEFINITIONS
• Do not add pool chemicals directly to the skimmer. This may damage the cell.
• Maintaining a salt and sanitizer level above the recommended range can contribute to the
corrosion of the pool equipment.
• Check the expiry date of the test kit as the test results may be inaccurate if the kit is used
after that date.
• If, due to heavy pool usage, it is required to increase the sanitizer level, then use a chemical
based on Trichloro-s-triazinetrione or sodium dichloro-s-triazinetrione dihydrate.
Preferred Water Chemistry Reading
Minimum Ideal Maximum
Free Chlorine 0 1.0 - 3.0 ppm 5.0 ppm
Combined Chlorine 0 0 ppm 0.2 ppm
pH 7.2 7.4 - 7.6 7.8
Total Alkalinity 40 ppm 80 ppm 120 ppm
Calcium Hardness 50 ppm 100 - 250 ppm 350 ppm
Stabilizer (Cyanuric Acid) 10 ppm 10 - 30 ppm 30 ppm
Free Chlorine -Is the chlorine residual present in pool water.
Combined Chlorine -Is formed by the reaction of free chlorine with ammonia wastes.
Result if too high - Sharp chlorinous odor, eye irritation.
pH
-A value that indicates how acidic or basic a solution is.
Result if too low - Corroded metals, eye & skin irritation,
destruction of total alkalinity.
Result if too high - Scale formation, cloudy water, shorter filter
runs, eye & skin irritation, poor chlorine
efficiency.
Total Alkalinity -Indicates the degree of the water’s resistance to change in pH. It
determines the speed and ease of pH change, so always adjust total
alkalinity before adjusting the pH level.
Result if too low - Corroded metals, eye & skin irritation. Low
alkalinity will cause the pH to be unstable.
Any chemical added to the water will have an
affect on pH.
Result if too high - Scale formation, cloudy water, eye & skin
irritation, poor chlorine efficiency.
Calcium Hardness -Refers to the amount of calcium and magnesium dissolved in the
water.
Result if too high - Eye & skin irritation, difficulty balancing water
and poor chlorine efficiency. Scale will form
and will cause the water to become cloudy.
Stabilizer
(Cyanuric Acid)
-Stabilizers extend the life of chlorine in swimming pools.
