This product is specially designed for above ground pools. It will destroy the bacteria, oxidize
bather organics and control algae, which provide you a safe, clean and comfortable swimming
pool.
Common salt (sodium chloride) is made up of two elements, sodium and chlorine. During the
installation of your Saltwater System/Filter Pump, a measured quantity of salt is dissolved in
the pool water to make it slightly salty. The pool water flows through the saltwater system’s
electrolytic cell (31) to produce HCLO. The HCLO dissolves in the water and instantly starts
destroying bacteria and algae. It also oxidizes all other organic materials.
The secondary electrolytic cell boosts the chlorination and sanitizing power for additional oxidation
of water contaminants.
HOW THE CHLORINE IS GENERATED
Wattage: 230 W
Ideal Salt Level: 3000 ppm (parts per million)
Maximum Chlorine Output/hour: 5 grams/hour
Secondary Cell Output Current: 500 mA
Type of filter medium: Synthetic cartridge #29000

SALTWATER SYSTEM/FILTER PUMP SETUP
Saltwater System/Filter Pump
1. Remove the Saltwater System/Filter Pump and hoses from the packaging.
2. Place the Saltwater System/Filter Pump in a location for hose (8) connections to the plunger
valve assemblies. Ensure the Saltwater System/Filter Pump is accessible at all time for
service and maintenance.
NOTE: Some regional regulations may require the filter pump to be mounted on a
stationary platform. There are two mounting holes located in the pump base for this
reason. Consult your local authorities for filter pump mounting requirements.
3. Grasp the two pump hoses (8) and connect the hose nuts to the Saltwater System/Filter
Pump.
4. In a counter-clockwise motion unscrew the threaded filter housing collar (3) from the filter
housing. Place it in a safe place.
5. The Saltwater System/Filter Pump is an airtight system. In a counter-clockwise motion turn
both air release valves (1 & 7) 1 - 2 turns to open. DO NOT remove air release valves as
water will expel with force if the motor is turned on and injury may occur.
6. Grasp and remove the filter housing cover (4). Check to see if a cartridge is inside the
housing. If yes, replace the cover, finger tighten the housing collar (3) back onto the filter
housing.
7. Gently finger tighten the sediment release valve located at the bottom of the housing to be
sure that water does not leak out.
8. When the pool is filled connect the hose from the electrolytic cell outlet to the highest strainer
assembly. You will find the hose connection at the bottom of the plunger valve assembly. Use
the hose nut to attach the hose.
9. Connect the second hose to the middle of the motor housing and to the remaining liner
connection.
IMPORTANT
To prevent air lock, open the lower plunger valve (connected inlet hose) first and then
the upper plunger valve (connected outlet hose). Open air release valves, lift and lower
the inlet hose until water starts to flow out of the air release valves, close air release
valves.

• Which kind of salt to use:
For use within the European Union, salt must be from an authorized salt supplier registered with
the European Chemicals Agency (ECHA) - visit echa.europa.eu. *
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 the
sanitizer. So, 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 sanitizer
production. A high salt level may generate a salty taste to the pool water (this may occur at a salt
level above 3500-4000 ppm). Too high of a salt level may damage the power supply and cause
corrosion to pool metal fixtures and accessories. The Salt Table page of this manual, shows the
correct dosage of salt needed. The salt in the pool is constantly recycled. Salt loss occurs only
when pool water is physically removed from the pool. Salt is not lost due to evaporation.
• Adding Salt
1. Switch on the unit, then press and hold both and button for 5 seconds, the LED
flashes “FP”. The unit is now in a Filter pump working mode and 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 by not adding 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
until you hear a “beep”, code “00” flashing (see “System Operation” section steps 2 to 4) 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.
• Pool Volume Calculation
* The European Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) requires that
salt (sodium chloride) used as a precursor for on-site generation of active chlorine by electrolysis
must be registered by the salt supplier with the European Chemicals Agency (ECHA), and such
supplier must be included on ECHA's list of authorized suppliers (Article 95 list).

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 1% of the salt, i.e. 100 Lbs (45 Kgs) salt x 1% = 1 Lbs
(0.45 Kgs) cyanuric acid.
If the pool water is dirty, filthy or grimy, DO NOT add chlorine stabilizer (cyanuric acid) as

FILTER PUMP OPERATION
1. Make sure the unit is switched off. The switch is located on the control station.
2. Connect the power cord to a RCD protected electrical outlet.
3. Turn both plunger valve handles fully counter-clockwise until they stop. This opens the valve,
allowing water to flow into the filter pump.
4. With water flowing into unit, the water pressure will allow the air trapped inside to escape
from the air release valves (1 & 7). When all the air has escaped water will flow out of the
valves
(1 & 7). When this occurs gently finger tighten the valves in a clockwise direction.
5. Turn on the switch. The filter pump is now filtering the water.
6. The green "Pump" light on the control panel will light up, that indicates the filter pump is
running.
To prevent air lock, open the lower plunger valve (connected inlet hose) first and then
the upper plunger valve (connected outlet hose). Open air release valves, lift and lower
the inlet hose until water starts to flow out of the air release valves, close air release
valves.
IMPORTANT
WARNING
Risk of electric shock. Connect this product only to a grounding type receptacle
protected by a residual current device (RCD). Contact a qualified electrician if you
cannot verify that the receptacle is protected by a RCD. Use a qualified electrician to
install the RCD, which has a maximum rate of 30 mA. Do not use a portable residual
current device (PRCD).

SALTWATER SYSTEM OPERATION
1. Start up the unit:
Plug the power cord into the electrical outlet and test the
RCD (circuit breaker). Switch on the unit.
With the Filter Pump turned “ON” and operating. The
green "Pump" light on the control panel will be on
and flashing code “00” appears on the electronic control
station’s LED, indicating that the unit is ready to be
programmed. This is normal.
2. 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.
3. Lock keypad controls:
With the desired hour value showing, press button
until you hear a “beep”. The green “WORKING”
indicator on the control panel will light up within a few
seconds to indicate that the saltwater system has started
sanitizer production. 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
1 minute later.
4. Unlock & Readjust operating time if necessary:
The operating hours can be re-adjusted if necessary.
Press button until you hear a “beep” to unlock the keypad
and the current programmed time will flash. Repeat steps 2 to 3.
(1 to 12 hours max per cycle)

SALTWATER SYSTEM OPERATION (continued)
5. Boost cycle:
•First time installation, press and hold “BOOST” button for 5 seconds until the
indicator lights up and the LED display “80”. This indicates that the saltwater
system has started more chlorine sanitizer production. You can press and
hold the “BOOST” button for another 5 seconds until the indicator is off,
which will cancel the Boost cycle.
•The boost operating hours is 8 times the amount of time programmed into the
system, i.e. if your saltwater system operating time is 2 hours, the boost procedure will run
8 x 2 = 16 hours. After boost procedure has been completed, the system will automatically
switch to the normal working mode.
•After a heavy rain or if the pool is dirty, press the “BOOST” button to shock the pool again.
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 chlorine 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.
7. Running the pump alone without the Saltwater System:
To run the pump alone without the Saltwater System function,
press and hold both and buttons until you hear a “beep”,
the LED display will show “FP”. The pump is now operating
alone. NOTE: The pump cannot be operated alone under an
automatic timer mode. To stop the pump, manually turn
the switch OFF.
To bring back the initial automatic operating cycle setting
of the Saltwater System:
a) If the LED display shows “FP”, press the button and
the operating hours set previously will begin flashing,
press the button again or simply wait 1 minute, and
the LED will stay illuminated. The Saltwater System
cycle repeats again.
b) If the unit is OFF, turn the switch ON, the LED display
shows “FP”, press the button and the operating hours
set previously will begin flashing, press the button
again or simply wait 1 minute, and the LED will stay
illuminated. The Saltwater System cycle repeats again.
