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.
