Suggested Preventive Maintenance Inspection Schedule
The Culligan HE 1.5 Twin 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.
Table 10.
Component Suggested Inspection
Frequency
Reason for Maintenance
Entire System At Startup, 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 harm-
less sulfate-reducing bacteria) may indicate a need for the
system to be sanitized. See “Sanitize the System” on page
37 .
Backwash Flow
Controller
Every 12 months or every time ser-
vice 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 nor-
mal (or unexpected) wear.
HE 1.5 Valve 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.Monitor item for nor-
mal (or unexpected) wear.
Softening Media Every 2–3 years Chlorinated water supplies can break-down/destroy resin
material. Resin material may also perform poorly if subject-
ed to other materials (sediment, iron, alum, etc) found in
some water supplies (but not necessarily all).
Application Problems
Many service problems are not due to equipment malfunction, but rather to misapplication or environmental conditions.
The
“Performance Specifications” on page 3 provide the limits of water characteristics for the HE 1.5 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 flow rates and exchange capacities are also listed.
Flow Rates—the backwash, brine, and slow rinse flows should not differ from those in
“High Efficiency Twin 1.5 Water
Softeners—Flow Rate Data (gpm)” on page 66 by more than 15 percent.
Refill Minutes/Salt Dosage/Capacity 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 require-
ment. If the hardness or water usage has increased, a higher salt dosage, more frequent regeneration, or a larger soften-
er may be needed. See Table 9 on page 36 .
If there are no apparent general problems or environmental problems, refer to “General Troubleshooting” on page 46 .
