SystemDescription
Accu-Tab®Series 100 Chlorination System
The Accu-Tab®Series 100 Chlorination System incorporates an Axiall LLC chlorinator, which is designed to utilize Axiall
LLC’s Accu-Tab®Blue SI Chlorinating Tablets. Using a manually adjusted valve and flow meter, the amount of water
through the chlorinator is controlled. This results in a constant and predictable rate of chlorine delivery. The chlorination
system is designed for use ONLY with Axiall LLC Accu-Tab®Blue SI Chlorinating Tablets to utilize the Axiall LLC erosion
feeder technology that erodes only the bottom layer of tablets on the sieve plate, while keeping tablets above the sieve
plate dry and ready for use. Tablets other than Axiall LLC Accu-Tab®Blue SI Chlorinating Tablets will have different
delivery rates, resulting in improper chlorine delivery.

Operation
To refill the chlorinator
1. Remove the lid. (Be careful not to inhale fumes.)
2. Fill the chlorinator with Accu-Tab®Blue SI
Chlorinating Tablets. Do not over fill.
3. Replace the lid.
To operate the chlorinator
1. Start flow through the chlorinator. Important:
For Suction Return - Open the supply service
valve BEFORE opening the discharge service
valve to assure water flow.
2. Adjust the control valve to the desired setting.
Check Available Chlorine regularly to determine
the best setting.
3. Adjust the control valve and refill the chlorinator
as needed to maintain chlorine levels.
Note: When pool circulation stops, flow to the
chlorinator will stop. This will stop chlorine delivery.
Note: In Gravity Return applications, the float valve will
simply hang down and function as a fully open valve.
Note: In Suction Return applications, the float valve will
function to keep a solution level in the chlorinator,
preventing air from entering the pump suction.
Cleaning
The chlorinator should be cleaned twice per year to
remove any residual product that may accumulate inside
the unit. Cleaning may be accomplished by soaking in a
dilute acid solution. Addition of muriatic acid will lower
the pH of the water. Be prepared to add a suitable pH
increaser after cleaning is complete
Preparation for cleaning:
1. Have 1 gallon of muriatic acid ready to add to
the chlorinator. Wear rubber gloves and rinse all
equipment thoroughly when finished.
2. Have a clean, empty container for storage of any
tablets inside the chlorinator.
3. Always use appropriate safety equipment while
servicing the chlorinator or handling chemicals.
To clean the chlorinator while installed:
1. Isolate the chlorinator from the system by
closing both the discharge and supply service
valves.
2. Remove the lid and remove all the tablets from
the chlorinator. Temporarily place these tablets
in the clean, empty container.
3. Rinse the chlorinator with water and (with the lid
removed) open the discharge service valve
temporarily to drain the chlorinator.
4. Close the discharge service valve and repeat
step #3 once.
5. Close the discharge service valve and fill the
chlorinator with water so there is about one inch
of water above the sieve plate. Using rubber
gloves and other safety protection, carefully pour
the muriatic acid into the chlorinator including
the walls of the chlorinator. ALWAYS ADD
ACID TO WATER, NEVER ADD WATER TO
ACID. Leave the lid removed and do not
breathe any fumes. Let soak for 30 minutes.
6. After 30 minutes, open the discharge service
valve. Open the supply service valve and flush
the chlorinator for 30 minutes at 5 gpm.
7. After 30 minutes of flushing, isolate the
chlorinator and rinse the walls with water. Drain
the chlorinator by temporarily opening the
discharge service valve. Rinse a second time
and drain.
8. Cleaning is now complete.
