Operation, Care & Maintenance 43
Application Problems
Many service problems are not due to equipment malfunction, but rather to misapplication or environmental conditions.
The Operation & Performance Specifications (page 5 of this manual) provides the limits of water characteristics for the Culligan
Medallist 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.
Table 5 - Salt Dosage/Capacity shows the gallon capabilities for each unit as a function of salt dosage. If the hardness or water
usage has increased, a higher salt dosage, more frequent regeneration, or a larger softener may be needed.
If there are no apparent general problems or environmental problems, refer to pages 44-46.
Recommended Preventative Maintenance Inspection Schedule
The Culligan Medallist Series water softener has been designed to provide a good, consistent service life. Routinely inspecting the
system may help avoid potentially costly breakdowns related to circumstances outside of the control of the dealer and/or user.
Table 9
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 42.
Backwash Flow Controller Every 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. Monitor item for normal
or unexpected wear.
Brine Eductor Nozzle and Throat Every 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. Monitor item for normal
or unexpected wear.
Softening Media Every 2 - 3 years Chlorinated water supplies can
breakdown and destroy resin 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).
Note: 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 3 - Flow Rates; high or low pressure installations may require the substitution
of a different refill flow control.
