CO- 5.6.0 TROUBLESHOOTING UNSTABLE CONDUCTIVITY
Proceed through the following SEVEN STEPS until a problem is located:
1. ENSURE a ‘strong’ spring was NOT accidently installed at the output ports of the acid AND
bicarbonate pump. BOTH pumps get ‘weak’ springs!
2. Compare both springs to new springs. Replace any that are shorter than a new spring.
3. Other procedures, in different Sections of the Guide, are performed next.
NOTE this page and
procedure number (CO- 5.6.0) because you may be prompted to return here.
4. If not already performed in THIS Troubleshooting session, BEFORE continuing to step #5, proceed to
page 580, to perform SECTION 19 - TESTING FOR A LEAKING BALANCING CHAMBER
DIAPHRAGM.
5. If a bad balancing chamber diaphragm was not located in step #4, BEFORE continuing to step #6,
proceed to
page 150, to perform PRESSURE TEST HYDROCHAMBER.
6. If the Hydrochamber was not leaking (per step #5), ENSURE Deaeration Motor brushes have been
replaced at 8000 hour intervals AND Flow Motor brushes have been replaced approximately at 16,000
hour intervals.
7. Assuming ALL procedures were performed thoroughly AND Conductivity remains unstable the
Troubleshooting Guide is unable to locate the problem.
