Description
The Accu-Tab PowerBase 3070AT chlorination system incorporates an Axiall
chlorinator into a compact plug and play system. Included in the system is an
integrated, level controlled solution tank and a centrifugal pump. The flow rate
through the system is controlled by a manually adjusted valve located on the
discharge of the pump. The solution tank level is controlled by a float valve. As
solution is pulled from the tank, the float valve opens allowing water to flow to the
chlorinator, contacting the tablets, and then draining into the solution tank.
Overflow protection is standard. Two level switches in the top area of the
Solution Tank (4” apart) will flip a relay in the electrical box causing the pump to
turn on/off as needed.
The chlorination system is designed for use ONLY with Axiall Accu-TabBlue SI
tablets utilizing the Axiall 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 Accu-TabBlue SI tablets will have
different delivery rates, resulting in improper chlorine delivery.

Installation Instructions
1. Place the chlorination system in a location near the place of application.
2. Level the system. This is important for proper chlorine delivery.
3. Connect the inlet flow meter assembly to the solution tank. The parts were
shipped separately to prevent breakage in shipping.
4. Connect the inlet water supply with 1-1/2” PVC pipe or hose. Include an
isolation valve in the line and the inlet filter.
5. Connect the discharge assembly to the pump using a section of 1-1/2” pipe.
(The parts were shipped loose to prevent breakage in shipment.)
6. Connect the discharge piping from the feeder to the chlorine application
point with 1-1/2” PVC pipe or hose. Include an isolation valve in the line.
7. Plug the power cord into an120v receptacle.

4
8. If a chemical controller is utilized, plug the controller cord into the
controller’s 120v switched output.
NOTE: IF A HIGH PRESSURE WEBTROL PUMP IS ORDERED, A LARGER
CAPACITY PUMP CONTACTOR IS INSTALLED IN THE ELECTRICAL BOX
AND NO CORD/PLUG IS PROVIDED AS A 25 AMP CIRCUIT IS REQUIRED.

Start Up
1. Close the discharge gate valve.
2. Open the feed and discharge isolation valves. Water will begin to fill the
solution tank.
3. When water stops flowing, switch the system “ON” using the chemical
controller. The pump will circulate water through the black tubing.
4. Begin opening the discharge gate valve to start flow in and out of the system.
5. Determine the maximum inlet flow rate by continuing to open the discharge
gate valve in small increments. Remember to allow a few minutes each time
to allow the flow meter to stabilize. If pump loses prime, maximum inlet flow
has been exceeded. Shut down system for a few minutes (which will prime
the pump), close back on the discharge gate valve and restart the system.
Continue this process until the maximum inlet flow is determined.
6. Adjust flow through feeder using the discharge gate valve. The chlorine
delivery is determined by the flow rate through the chlorinator. Use the graph
above to determine proper flow rate. NOTE: After adjusting the discharge
valve, the flow meter will take a few moments to stabilize.
7. Check all piping for leaks.

Operation
1. Remove lid from chlorinator and fill with the appropriate amount of Accu-Tab
Blue SI tablets. Add no more than the amount of tablets that will be used
within one week.
2. Check pool water for desired chlorine level and adjust flow through chlorinator
as needed.
NOTE: When pool water circulation stops, flow to chlorinator will stop. This
will stop chlorine delivery.
Adding Tablets
1. Tablets may be added while the system is running. Take care to protect eyes,
skin, clothing and other equipment from splashing. Do not inhale fumes.
2. Remove lid and add Accu-TabBlue SI tablets.
3. Replace lid.
Maintenance
Clean the Check Valve and Float Valve at least every 4-6
months, or as needed, to remove scale or debris
Winterizing
1. Clean chlorination system following instructions below.
2. Close inlet isolation valve and operate pump until no more water can be
pumped out.
3. Shut system down and close the outlet isolation valve.
4. Siphon any remaining water from the solution tank.
5. Remove any debris from the chlorinator or solution tank.
6. Open the bottom drain on the pump.
7. Drain water from feed and discharge lines.
8. Make sure no water remains in the pump, chlorinator, pipe line, or solution
tank to prevent freezing over the winter.
System Cleaning
Over time the chlorination system may develop a build-up of scale. This
should be cleaned on a periodic basis, up to twice per year. If scale formation
is severe, more frequent cleanings may be necessary. Cleaning may be
accomplished by soaking the chlorinator with a dilute acid solution according
to the instructions below.
NOTE: Addition of muriatic acid may lower the pH of the pool water

7
Preparation for cleaning
1. Prepare 2 gallons of muriatic acid.
2. Always use appropriate safety equipment while servicing the unit or handling
chemicals.
3. Clean the feeder in a well-ventilated area. Chlorine gas may be released
during the cleaning process!
Inlet/Outlet Bypass
To facilitate the cleaning process a Bypass may be installed between the inlet
and outlet lines to/from the chlorination system. Isolation valves at the
recirculation line are required.
1. Turn system off.
2. Open lid and remove all tablets. Use proper protective equipment when
handling chemicals.
3. Switch system on to begin flushing the system.
4. Wash out the feeder with a hose to remove remnants of tablets and loosen
scale.
5. Operate system until normal solution tank level is achieved. Switch system
off.
6. Close inlet and outlet isolation valves and open inlet/outlet Bypass valve (if
installed).
7. Very carefully, pour the acid into the upper chlorinator to dissolve scale. It
may be necessary to pour directly on the inside walls to remove any scale
above the water level. Always add acid to water, never add water to acid.
8. Let soak for 30 minutes. As acid dissolves scale, carbon dioxide will be
released, and foaming will occur. If any tablets were left in the feeder,
chlorine gas may also be released.
9. Turn system on to start acid circulation through the blue tubing. Circulate for
10 minutes.
10. Open all valves to begin purging acid from system. Shut Bypass Valve.
11. Wash the walls and sieve plate of the feeder with a hose to remove all acid
residue. Chlorine gas may be released if any acid remains in the system.
12. Allow feeder to flush water for 30 minutes.
13. Turn system off. System is ready for operation.

Troubleshooting
System overflows.
1. Debris in the float valve.
2. Debris in the check valve.
3. Float valve stuck in down position. Clean float valve.
Pump will not run.
1. Check power supply and connections, and controller 110v signal.
2. Check for 110 voltage across terminals #2 and #5. If voltage present, wiring or
pump motor failure.
Pump loses prime (solution tank drains)
1. Maximum inlet flow exceeded. See Start-Up instructions—point #5.
Float Valve maintenance
If valve becomes clogged with debris on a continuing basis, add a second filter to
the inlet. Use the 60 mesh in the first filter then a 100 mesh in the second. The
100 mesh filter can be supplied by your specialist.
Chlorinator Top Orientation
Align the chlorinator top portion so that the pointer on the separation plate is
directly over the inlet –see photo below. This will prevent chlorine solution from
draining directly onto the float valve assembly.
