Installation and Operating Instructions
DANGER: DO NOT MIX CHEMICALS!
The PowerBase 3070AT chlorinator system is
designed for use with PPG approved tablets
only. Do not mix Cal-Hypo tablets with stabilized
chlorine or bromine products, or other sanitizing
chemicals. Fire or explosion could result.

NSF-50
The PowerBase® 3070AT Chlorinator is
NSF-Listed for pool and spa applications.
ONLY PPG Accu-Tab® Blue SI Tablets for
commercial pool applications are
permitted for NSF installations. Use of
other tablets will void NSF certification.

Description
The Accu-Tab PowerBase 3070AT chlorination system incorporates a patented
PPG 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.
The chlorination system is designed for use ONLY with PPG Accu-Tab Blue SI
tablets utilizing the PPG patented 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 PPG Accu-Tab Blue SI tablets will
have different delivery rates, resulting in improper chlorine delivery. The PPG
PowerBase 3070AT is protected under patent #5,427,748.
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 loose to prevent breakage in shipping)
4. Connect the inlet water supply with 1-1/2” PVC pipe or hose. Include an isola-
tion valve in the line.

7. 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.)
8. 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.
9. Plug the power cord into an 110v receptacle.
10. If a chemical controller is utilized, plug the controller cord into the
controller’s 110v switched output.
11. If system is to run manually without a chemical controller, install jumpers as
shown in the electrical schematic on page 9 of this manual.

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 blue 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 PPG
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 chlorina-
tor 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 PPG Accu-Tab Blue 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
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 dur-
ing the cleaning process!
Cleaning procedure
1. Turn system off.
2. Open lid and remove all tablets. Use proper protective equipment when han-
dling 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.
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 re-
leased, 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.
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.
