INTRODUCTION
MPORTANT NOTICE: The filter pump attached to the chlorinator can run for a maximum of 8 hrs/day.
The chlorinator should not be on when the filter pump is not working.
Common salt (sodium chloride) is made up of two elements, sodium and chloride. During the installation
of your chlorinator, a measured quantity of salt is dissolved in the pool water to create a mild saline
solution. As part of the daily filtration cycle, the pool water is passed through the chlorinator’s electrolytic
cell to produce chlorine which is dissolved instantly in the water. In simple, non-technical terms, the
chlorine instantly starts to destroy bacteria, algae and oxidized other organic materials.
Electrolytic Cell (with Titanium Plates)
The electrolytic cell contains bipolar titanium electrodes which perform the electrolysis and produce
chlorine when energized with DC current. Chlorine is generated as pool water containing salt passes
through the cell. The chlorine production can be varied by changing the number of hours the chlorinator is
on each day. The chlorinator automatically reverses the cell electrode titanium plates every twenty hours
to clean the cell. This process does not interrupt the chlorine production.
When replacing the cell, only use replacement cells having a label that clearly states that it is a
replacement cell for the chlorine generating device Hydro-Force Flowclear Chlorinator Model 58215,
REGISTRATION NUMBER 30383, PEST CONTROL PRODUCTS ACT.

• Flow Sensor The flow sensor protects the electrolytic cell and assures that will always be adequate water
flowing through the cell. When the water flow drops below the minimum flow rate, the electrolytic cell
will automatically shut down to protect the titanium plates and no chlorine will be produced.
• Control Panel The chlorinator includes a electronic control panel with buttons and LED indicators to
control the chlorinator and produce chlorine at the defined operating hours. The chlorinator also
measures the different parameters such as salt level and water flow. If any deviation from the norm occurs
then a LED indicator will light to indicate the problem.

PARTS REFERENCE
Before assembly, take a few minutes to become familiar with all the parts.
NOTE: Drawings for illustration purpose only. May not reflect actual product. Not to scale.

POOL WATER CHEMISTRY
Minimum Ideal Maximum Optimum Pool Water Chemistry Conditions It is recommended that the
following pool water chemistry conditions be checked daily and maintained. This will help to protect pool
users, pool related equipment and surfaces in and around the pool. These values are important to
maintaining the pool equipment in proper operating condition and preventing corrosion or other problems.
The chlorinator is warranted to operate properly only if these conditions are met. For more information,
please consult with your local swimming pool dealer for water treatment.
• Free Chlorine is the chlorine residual present in pool water.
• Combined Chlorine is formed by the reaction of free chlorine with ammonia wastes.
NOTE: If combined chlorine is too high, it will result in sharp chlorinous odour and eye irritation.
• pH - A value that indicates how acidic or basic a solution is.
NOTE: If pH is too low, it will result in corroded metals, eye & skin irritation and destruction of total
alkalinity. If pH is too high, it will result in scale formation, cloudy water, eye & skin irritation and 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.
NOTE: If total alkalinity is too low, it will result in corroded metals, eye & skin irritation. Low alkalinity
will cause the pH to be unstable. Any chemical added to the water will have an effect on pH. If total
alkalinity is too high, it will result in scale formation, cloudy water, eye & skin irritation and poor
chlorine efficiency.
• Calcium Hardness refers to the amount of calcium and magnesium dissolved in the water.
NOTE: If calcium hardness is too high, it will result in scale formation and cloudy water.
• Stabilizer (Cyanuric Acid) - Stabilizers extend the life of chlorine for outdoor swimming pools.
What Type of Salt to Use?
The purer the salt, the better the life and performance of the chlorinator. 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. Consult your salt supplier.
Optimum Salt Level
The ideal salt level in the pool water is between 4000~5000ppm (parts per million) and the optimum salt
level in the pool water is 4500ppm (parts per million). A too low salt level will reduce the efficiency of
the chlorinator and result in low chlorine production. A high salt level may begin to generate a salty taste
to your pool water. Too high of a salt level may damage the power supply and cause corrosion to pool
metal fixtures and accessories. The following 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. Switch on the filter to circulate the pool water.
2. Keep the chlorinator “OFF”.
3. Determine the amount of salt according to the following table.
4. Evenly and slowly pour in the salt around the inside perimeter of the pool. To avoid clogging the filter,
do not add salt through the skimmer.
5. Brush the pool bottom to speed up the dissolving process. Do not allow salt to pile up on the pool
bottom. Run the filter 24 hours to dissolve salt completely.
6. After 24 hours, refer the OPERATION INSTURCTION section to check water flow status. If the water
flow status is normal, you can set the chlorinator to the desired operating time.
Removing Salt
If too much salt has been added, the Red LED salt level light will light up. 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 Red LED salt level light
disappears with the Green LED salt level light on.

OPERATION INSTRUCTIONS
NOTE: After the salt is dissolved, but before operating the chlorinator be sure that:
• The filter pump/sand filter and the chlorinator are connected to a grounding type receptacle protected by
a ground-fault circuit-interrupter (GFCI).
• The filter pump/sand filter operates several minutes before operating the chlorinator. This removes air
pockets and debris in the water hoses.
• No air is trapped in any of the hoses. Follow the filter pump/sand filter manual to release any trapped
air.
1. After running the filter for 24 hours to dissolve salt completely, unplug the filter and plug the
chlorinator into the electrical outlet. At the same time, the LED light above the On-Off button displays
red. After pressing the On-Off Button, the LED light above this button displays green. At the same time,
the flow status LED indicator displays red, which is normal.
2. Turn off the chlorinator and plug the filter into the electrical outlet. After turning on the chlorinator
again, the LED light above the On-Off button turns green. Press and hold both the
buttons together for 3 seconds until you hear a long “beep” to unlock the keypad time buttons.
3. Determine the operating time according to Table 2 or Table 5. Press button or button
to increase or decrease the operating time from 2 hours to 12 hours. At the same time the corresponding
operating time LED lights will flash. After you set the proper operating time, press and hold both the
and buttons together for 3 seconds until you hear a long “beep” to re-lock the keypad time
buttons. At the same time the operating time LED lights will stop flashing. Then the salt level and water

flow will be checked and the corresponding LED indicators will be displayed. The unit will now operate
for the operating time you set at the same time each day.
NOTE: The default operating time is 2 hours.
NOTE: The chlorinator will not operate if the filter pump/sand filter is not operating.
NOTE: With locking the time buttons into this setting, you will have prevented unauthorized changing of
the operating time.
NOTE: If you forget to re-lock the keypad time buttons, the unit will automatically lock the keypad time
buttons 5 seconds later and you will hear a long “beep”.

5. The operating time LED lights will disappear one after the other when the unit operates. The operating
time LED lights show the remaining hours in the daily operating cycle.
6. All the LED indicator lights will disappear except that the light above the On-Off Button displays
yellow when the chlorinating cycle ends. The unit automatically goes in to a power saving mode and
will automatically turn itself back on in 24 hours to continue its daily chlorine production. Press any
button to view the last status of the LED lights.
IMPORTANT: Check the expiry date of the test kit as test results may be inaccurate if used after that
date. Do not operate the chlorinator while the pool is in use or occupied.
• Always use a test trip 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 3ppm before using the pool or operating the
chlorinator.
• Heavy pool usage and higher temperatures may require higher chlorine output (longer operating time) to
maintain proper free available chlorine residuals.
• If a power outage occurs or the power cord is unplugged then the chlorinator operating time will have to
be reset.

MAINTENANCE
CAUTION: You must ensure the chlorinator is unplugged before any maintenance begins or severe risk
of injury or death exists.
Flow Sensor Cleaning
1. Unscrew the locked nut of the flow sensor counter-clockwise and disconnect the flow sensor signal
line. Then remove them from the flow sensor.
2. If deposits and debris are found on the surface of the flow sensor, then use a garden hose to clean it
thoroughly.(See Fig. 1)
3. If the deposits can not be removed after step 2, use a plastic brush (do not use a metal brush) to clean
the flow sensor if necessary.
4. After the flow sensor has been inspected and cleaned, reinstall the flow sensor signal line and the
locked nut tightening the flow sensor back into its position. Do not over tighten.
Electrolytic Cell Cleaning
The electrolytic cell has a self-cleaning feature that reduces scale buildup on the titanium plates of cell. In
most cases, this self-cleaning function will keep the cell working at optimum efficiency. If the pool water
is hard (high mineral content), the cell may need periodic manual cleaning. To extend the life and
performance of the electrolytic cell, it is recommended that you should inspect the electrolytic cell every
3 months and clean it if necessary. Follow the cleaning instructions below.
1. Turn off the chlorinator and unplug the power cord from the electrical outlet.
2. To prevent water from escaping the pool, remove the debris screens from the inside of the pool and
insert the stopper plugs in the pool’s inlet and outlet valves or close the connection valves.
3. Unplug the electrolytic cell line cord.
4. Disconnect the connecting hose from the electrolytic cell.

5. Disconnect the adaptor from the chlorinator outlet. Look inside the electrolytic cell inspecting for scale
formation (light colored crusty or flaky deposits) on the titanium plates. If no deposits and debris are
visible, reinstall the adaptor and connecting hose. (See Fig. 2)
6. If deposits and debris are found on the titanium plates, use a high pressure garden hose and try to flush
them out. Only flush from the direction of water inlet to avoid damaging the flow sensor. Do not use any
metal tool because this will scratch the coating off the plates.
NOTE: 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 Water Chemistry” for reference.
7. If flushing does not remove the deposits on the plates then disconnect the cell from the base by
removing the 4 mounting screws. Disconnect the flow sensor from the top of the cell and unplug the
electrolytic cell line cord. Soak the cell in a vinegar solution (condiment) for 2-3 hours and flush with
high pressure water from the garden hose.
8. Reinstall the electrolytic cell reversing steps 3, 4, 5 & 6. (Reset the operating time of the chlorinator)
When replacing the cell, only use replacement cells having a label that clearly states that it is a
replacement cell for the chlorine generating device. Hydro-Force Flowclear Chlorinator Model 58215,
REGISTRATION NUMBER 30383, PEST CONTROL PRODUCTS ACT.
STORAGE
1. Unplug the power cord from the electrical outlet.
2. After all water is drained from the pool, disconnect the chlorinator from the hoses.
3. Air-dry the chlorinator before storage. It is recommended to visually inspect and clean the electrolytic
cell at this time.
4. It is recommended you store the chlorinator in its original package in a warm dry place.
BESTWAY TEST STRIPS (Included in the package)
Test Strips can test the “Free Chlorine”, “PH” and “Total Alkalinity” levels at the same time.
Use as follows.
1. Dip one strip into water, no more than 46cm (18”) below the water surface and remove immediately.
2. Hold strip level for 15 seconds to avoid reactant dripping from one tests pad to another.
NOTE: Do not shake off excess water.
