Preventive Maintenance - Culligan High Efficiency 1.5 Twin Series Installation, Operation And Service Instructions

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.
Component Suggested Inspection
Entire System At Startup, after infrequent use (idle
for one week or more) or every 3–6
months if on a private water supply.
Backwash Flow Every 12 months or every time ser-
Controller vice is performed on the system.
HE 1.5 Valve Every 6–12 months or every time
service is performed on the system.
Softening Media Every 2–3 years
Application Problems
Many service problems are not due to equipment malfunction, but rather to misapplication or environmental conditions.
The "Performance Specifications" on page 3
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
Softeners—Flow Rate Data (gpm)" on page 66
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

Preventive Maintenance

Reason for Maintenance
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
37.
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.

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).
