Product Information and Specifications
How the Chlorine is Generated
Common salt (sodium chloride) is made up of two elements, sodium and chloride. 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. This pool water is passed through the Saltwater System’s electrolytic cell to produce chlorine
which is dissolved instantly in the water. The chlorine instantly starts to destroy bacteria, viruses, algae and
oxidizes other organic materials.
Key Saltwater System Parts:
•Power Supply
The power supply converts AC electrical current to a low voltage DC current. This is required by the
cell to perform the electrolysis that creates chlorine.
•Electrolytic Cell (with Titanium Plates)
The electrolytic cell contains bipolar titanium electrodes which perform the electrolysis and produce liquid
chlorine when energized with DC electricity. Chlorine is generated when pool water containing salt
passes through the cell. The chlorine production can be varied by changing the number of hours the
Saltwater System is operating each day. The Saltwater System has a built-in self cleaning cycle that
operates every two hours without interrupting chlorine production.
•Flow Sensor
The flow sensor protects the electrolytic cell and ensures there is adequate water flowing through the
cell. When the water flow drops below minimum flow rate, the electrolytic cell will automatically shut
down to protect the titanium plates. A safety buzzer will sound and the LED display panel will show a
signal code (see “LED Code Chart”) indicating the problem.
•Electronic Control Station
The electronic control station contains an LED display panel and a set of pushbuttons to program the
Saltwater System operating hours. It also monitors the different parameters such as salt level, water
flow and the electrolytic cell activity. If any deviation from the norm occurs then a buzzer will sound and
the LED display panel will show a signal code (see “LED Code Chart”) indicating the problem.

Strainer & Plunger Valve Set Up (16’ and below AGP)
The Saltwater System/Filter Pump assembly includes two (2) strainer-control mechanisms that are to
be installed in the pool liner's two (2) protruding hose connections with adaptor B. The strainer grid
prevents large objects from jamming and/or damaging the filter pump and the plunger valve assembly
prevents water from flowing into the filter pump while the filter cartridge is being placed or cleaned.
Install the strainer and plunger valve before inflating the pool liner top ring.
1. Grasp the strainer and plunger valve mechanism.
2. In a counter-clockwise motion unscrew plunger valve union from the threaded strainer connector
(06NF-02). Be careful not to lose the step rubber washer (06NF-05).
3. Grasp the plunger valve assembly. Make sure the step washer (06NF-05) is in place. Connect
adaptor B (05CG-12) to plunger valve union.
4. Repeat steps 1 through 3 for another plunger valve.
5. Remove wall plug and then insert the strainer (F12) into each of the protruding hose connection.
Adaptor B (05CG-12) fit over the strainer inserted into the connection.
6. Examine the plunger valve to see if the handle is pushed fully down to the "0/1" position. If not,
then grasp the handle at the top and push down turning the handle in a clockwise direction until the
plastic protruding notch anchors in the "0/1" position. This will prevent water from flowing out during
filling.
7. Repeat steps 1 through 6 for the 2nd protruding hose connection.
8. The pool liner is now ready to fill with water. Consult the above-ground-pool owner's manual for
filling instructions.

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 (5NF19) connections to the plunger
valve assemblies.
Note: Some regional regulations may require the filter pump to be mounted on a stationary
platform.There are two (2) mounting holes located in the pump base for this reason.
Consult your local authorities for filter pump mounting requirements.
3. Grasp the two (2) pump hoses (5NF19) and connect the hose nuts to the Saltwater Pool
System/Filter Pump.
4. In a counter-clockwise motion unscrew the threaded filter housing collar (6F16) 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 (5F12 & 05F-37) 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 (6F14). Check to see if a cartridge is inside the housing.
If yes, replace the cover, finger tighten the housing collar (6F16) 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. The hose connection is made at the bottom of the plunger valve assembly. Use the hose
nut to attach the hose.
9. Connect the 2nd hose to the middle of the motor housing and to the remaining liner connection.

Salt & Pool Water Volumes
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), but it will take 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 this salt to create chlorine, 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) with 3000 ppm
being optimal.
A too low salt level will reduce the efficiency of the Saltwater System and result in low chlorine
production. A high salt level may begin to generate a salty taste to your pool water (this may occur at a
salt level above 3500-4000ppm). Too high of a salt level may damage the power supply and cause
corrosion to pool metal fixtures and accessories. The following “salt table” shows the quantity of salt to
use. The salt in the pool is constantly recycled. Salt loss is due only to pool water physically removed
from the pool. Salt is not lost due to evaporation.
How to Add or Remove Salt
Adding Salt
1. Depress the ON button on the filter pump switch to circulate pool water.
2. Keep the Saltwater System “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. To 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 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
need to lower the salt concentration. The only way to lower the salt concentration is to partially drain the
pool and refill with fresh water. Drain and refill approximately 20% of the pool’s water until the “Code 92”
disappears.

Operating Instructions
This unit is the combination of filter pump and Saltwater System.
Filter Pump Operation
1. Make sure the unit switch is "OFF". The switch is located on the control box.
2. Connect the power cord to a GFCI protected electrical outlet.
IMPORTANT: To prevent air lock, open the lower plunger valve (connected inlet hose) first
and then the upper plunger valve (connected outlet hose).
3. Grasp a plunger valve handle. Turn the handle counter-clockwise, pull up until it stops, and then
turn it clockwise until the metal protruding notch anchors in the "0/1" position. Repeat for the 2nd
plunger valve. This opens the valves to allow water to flow into the unit.
4. With water flowing into unit, the water pressure will allow the air trapped inside to escape from the
air release valves (5F12 & 05F-37). When all the air has escaped water will flow out of the valves
(5F12 & 05F-37). When this occurs gently finger tighten the valves in a clockwise direction.
5. Turn the switch "ON". The filter pump is now filtering the water.
6. A yellow LED Light on the control panel will light up, that indicates the filter pump is running.

Operating Instructions (Cont.)
Saltwater System Operation
After the salt is dissolved, but before starting the chlorine generation be sure that:
•The system is connected to a grounding type receptacle protected by a ground-fault circuit
interrupter (GFCI).
•The filter pump operates several minutes before starting the Saltwater System (This removes
air pockets and debris in the water hoses).
•No air is trapped in any of the hoses. Follow “Filter Pump Operation” above to release any trapped
air.
1. With the Filter Pump turned “ON” and operating. Code “88” appears on the
electronic control station’s LED indicating the unit is in a Stand-By Mode, this
is normal.
2. Unlock keypad controls:
Press and hold button for 5 seconds until you hear a short “beep”, then
press and hold button for another 5 seconds until you hear the second short
“beep”, LED flashes “00”. This procedure unlocks the keypad control buttons.
3. Set Saltwater System operating hours:
Increase the scheduled number of hours of operation by pressing
button, or reduce by pressing button. See “Operating Time
Table” for pool size and required operating hours. Press button
to select hours required, press if too many hours were selected.
The built-in timer will now operate for the number of hours selected
at the same time each day.
NOTE: The Saltwater System will not operate if the filter pump
is not operating.
4. Re-lock keypad controls:
With the proper hour value showing, press and hold button for 5 seconds
until you hear a long “beep”, then press and hold button for another 5
seconds until you hear the second long “beep”. A green LED light on the
control panel will light up within a few minutes, which indicates the saltwater
pool system starting chlorine production. Filter pump can be run alone
without the Saltwater System, with the proper hour value showing,
press and hold both and buttons for 5 seconds until you hear a long
“beep”. With locking the control buttons into this setting you will have prevented
unauthorized changing of the operating cycle.
5. Operating hours can be re-adjusted if necessary. Follow steps 2 thru 4.
6. The scheduled operating hours displayed on the LED readout will decrease to zero as the unit
operates. The LED shows “hours remaining” in the daily operating cycle.
(1 to 12 hours max per cycle)

7. The green and yellow LED lights on the control panel will disappear when the
cycle has ended. The system will go into a “Stand-By Mode” with the LED
flashing “93”. The system automatically goes into a “Power Saving Mode” and
will automatically turn itself back on in 24 hours to continue its daily chlorine
production.
8. The LED will be become blank after 1 hour indicating the Saltwater System
is dormant (Power Saving Mode) waiting for the next startup cycle to begin.
Press any button ( or ) to view the last LED code.
SPECIAL NOTES
•Always use a test strip to test the chlorine level before entering or using the pool. If the chlorine
level is too high, wait until the chlorine level drops below 3 ppm before using the pool or
operating the Saltwater System again.
•IMPORTANT: Never use the pool if chlorine level is more than 3 ppm. Do not operate
Saltwater System while the pool is in use or occupied.
•If a power outage occurs or the power cord is unplugged then the Saltwater System operating
hours will have to be reset.

Maintenance
IMPORTANT: Unplug power cord before cleaning and close plunger valves or insert black hat-like
plugs in strainer opening to prevent water spillage. Plug in the power cord and open plunger valves or
remove plugs when maintenance tasks are completed.
Flow Sensor Cleaning
1. In a counter-clockwise motion unscrew the collar of the flow sensor (05CG-04) and remove it from
the flow sensor conduit (05CG-06). See “Part Reference”.
2. If deposits and debris are seen on the surface of the flow sensor, then use a garden hose to wash
it off.
3. If flushing does not remove the deposits, use plastic brush (do not use a metal brush) to clean the
surface and the hinge if necessary.
4. After the flow sensor has been inspected and cleaned, align the locator notch on the flow
sensor to the connection ridge in the conduit, turn the collar in a clockwise motion tightening the
sensor back into its position. Do not over tighten.
Electrolytic Cell Cleaning
The electrolytic cell (05CG-01) has a self cleaning function incorporated into the electronic control's
programming. In most cases this self cleaning action will keep the cell working at optimum efficiency. If
the pool water is hard (high mineral content) the cell may require periodic manual cleaning. Follow the
cleaning instructions below. To maintain maximum performance, it is recommended that you open and
visually inspect the electrolytic cell (05CG-01) and debris screen (05CG-08) every 3 months.
Visual Inspection and Cleaning:
1. Switch off the unit, unplug the power cord from the electrical socket.
2. Grasp a plunger valve handle. Turn the handle counter-clockwise, push down until it stops and
then turn it clockwise until the plastic protruding notch anchors in the "0/I" position. Repeat for the
2nd plunger valve. This prevents the water from flowing out of the pool.

Maintenance (cont.)
3. Disconnect the water return (to the pool) hose from the Saltwater System outlet. Disconnect
angle joint (05CG-14) from the filter housing and flow sensor conduit (05CG-06).
4. Check for debris which has passed through the filter and been trapped on the debris screen
(05CG-08). If debris is on the debris screen, remove the debris screen and use garden hose to
flush the debris off.
5. Look inside the electrolytic cell (05CG-01) inspect for scale formation (light colored crusty or flaky
deposits) on the titanium plates. If no deposits and debris are visible reinstall the debris screen
(05CG-08), cell and hose.
6. If deposits and debris are seen on the titanium plates, use a high pressure garden hose and try to
flush them off. Only flush from the direction of water inlet to avoid damaging the flow sensor. Do
not use any metal tool as this will scratch the coating off the plates. Note that a buildup on the cell
indicates that there is an unusually high calcium level in the pool. If this is not corrected, you have
to frequently check and clean the cell. To avoid this, always keep your pool chemistry at the
recommended levels. See “Pool Maintenance & Chemical Definitions” for reference.
7. If flushing does not remove the deposits on the plate then disconnect the cell from the base by
removing the 2 mounting screws (05CG-03). Disconnect the flow sensor from the top of the cell
and unplug the electrolytic cell cord. Soak the cell in a vinegar solution (condiment) for 2-3 hours
and then flush with high pressure water from the garden hose.
8. Reconnect electrolytic cell reversing steps 3, 4, 5 and 7. (Reset the Saltwater System’s operating
hours)
NOTE: After cleaning the operating hours have to be reset.

2. Grasp a plunger valve handle. Turn the handle counter-clockwise, push down until it stops and
then turn it clockwise until the plastic protruding notch anchors in the "0/1" position. Repeat for the
2nd plunger valve. This prevents the water from flowing out of the pool.
3. Gently turn both air release valves (5F12 & 05F-37) 1-2 turns in a counter-clockwise direction. This
will allow the housing cover to be easily removed.
4. In a counter-clockwise direction remove the filter housing collar (6F16). Place it in a safe location.
5. Remove the housing cover (6F14).
6. Remove the "OLD" filter cartridge.
7. Examine the inside of the filter housing.
8. If dirt or sediment is located on the bottom of the housing then:
A. In a counter-clockwise motion gently unscrew and remove the sediment valve (5F12) located at
the bottom of the housing. Place it in a safe place.
B. With a bucket of water or a garden hose pour water into the housing flushing out the sediment.
C. In a gentle clockwise motion return the sediment valve (5F12) to its location.
Do not over-tighten.
9. Place a new cartridge filter in the housing.
10. Return the housing cover (6F14) to its position and in a clockwise direction rescrew the housing
collar (6F16) onto the filter housing.
11. Turn both plunger valve handles in a counter-clockwise direction, pull up until they stop, and then
turn them clockwise until the metal protruding notch anchors in the "0/1" position.
12. Reconnect the power cord.
13. Turn the unit "ON".
14. When the trapped air has escaped through the air release valves gently retighten the valves
(5F12 & 05F-37) in a clockwise direction.
Long Term Storage
1. Disconnect power cord from electrical outlet.
2. After pool is emptied of all water, disconnect the Saltwater System/Filter Pump from the pool
reversing the installation instructions.
3. Air-dry the unit before storage (It may be prudent to visually inspect and clean the electrolytic cell
at this time).
4. Store the unit and accessories in a dry, cool storage location.
