Cleaning procedure
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 black 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. DO NOT use any
lubricant on the valve internals.
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)
2. Maximum inlet flow exceeded. See Start-Up instructions—point #6.
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.
