58 Culligan® CSM Series Softeners
58 Cat. No. 01016370
Application Problems
Many service problems are not due to equipment malfunction, but rather to misapplication or environmental conditions.
The Operation & Performance Specifications
(page 2 of this manual) provides the limits of water characteristics for the CSM Series water softeners. If the water
characteristics fall outside these limits, additional water treatment equipment may be required, or the water characteristics
should be brought inside the limits. The system ow rates and exchange capacities are also listed.
Appendix A, "Table 14. CSM Series Water Softeners - Flow Rate Data (GPM)"
The backwash, brine, and slow rinse flows should not differ from those in Appendix A, "Table 14. CSM Series Water Soft-
eners - Flow Rate Data (GPM)" on page 92 by more than 15%.
Appendix A, "Table 15. CSM Refill Minutes/Salt Dosage/Capacity"
This table shows the hardness removal capabilities for each unit as a function of salt dosage and refill time. Multiply the
inlet hardness times the maximum daily water usage to determine the daily capacity requirement. If the hardness or water
usage has increased, a higher salt dosage, more frequent regeneration, or a larger softener may be needed.
NOTICE The rate at which brine is drawn from the brine tank should not differ by more than 5%. The refill
rate should be as close as possible to the rate shown in Appendix A, "Table 14. CSM Series Water
Softeners - Flow Rate Data (GPM)" on page 92; high or low pressure installations may require
the substitution of a different refill flow control.
If there are no apparent general problems or environmental problems, refer to "Troubleshooting Guide" on page 60.
Suggested Preventative Maintenance Inspection Schedule
The Culligan CSM series commercial water softener has been designed to provide a good, consistent service life. Rou-
tinely inspecting the system may help avoid potentially costly breakdowns related to circumstances outside of the control
of the dealer and/or user.
Component Suggested Inspection Frequency Reason for Maintenance
Entire System At Start-up, after infrequent use (idle for
one week or more) or every 3 - 6 months if
on a private water supply.
On private supplies, the appearance of off-tastes and
odors, particularly if musty or “rotten egg” (caused by
harmless sulfate-reducing bacteria) may indicate a
need for the system to be sanitized. See page 57.
Backwash Flow Every 12 months or every time service is
performed on the system.
Build up of sediment, iron and/or other foreign materi-
als (found in some water supplies but not necessarily
all) could negatively affect system performance.Monitor
item for normal (or unexpected) wear
Controller Every 6-12 months or every time service is
performed on the system.
Build up of sediment, iron and/or other foreign materi-
als (found in some water supplies but not necessarily
all) could negatively affect system performance.Monitor
item for normal (or unexpected) wear.
Pilot Valve
Assembly
Every 6-12 months or every time service is
performed on the system.

Brunermatic
Valve
Every 6-12 months or every time service is
performed on the system.

als (found in some water supplies but not necessarily

Pilot Strainer Every 6-12 months or every time service is
performed on the system.
Build up of sediment, iron and/or other foreign materials
(found in some water supplies but not necessarily all)
could negatively affect system performance.
Softening
Media
Every 2 - 3 years Chlorinated water supplies can break down/destroy res-
in material. Resin material may also perform poorly if
subjected to other materials (sediment, iron, alum, etc)
found in some water supplies (but not necessarily all).
