Culligan Hi-Flo®3 Water Softener Standard Features
• Positive Motor-Driven Regeneration Valve–Motor
driven piston is reliable under severe water conditions,
resists dirt, iron, turbidity.
• Automatic Brine Control—Automatically measures
the correct amount of brine. A single turn of dial sets
correct amount dosage and capacity.
• Dubl-Safe
™
Brine System—Positive overfill protection.
Automatic refill control is backed up by shutoff float
valve to minimize chance of overflow.
• Corrosion Resistant Tanks–made from fiberglassreinforced polyester. Additional reinforcement from
continuous fiberglass overwrap. Underdrain design
maximizes softener’s capacity, reduces pressure loss.
• Softening Media—High quality resin provides stability
and uniform size for top performance and long life.
• Choice of Cycle Controllers—Regeneration cycle may
be initiated by timeclock any or every day of the week.
Optional meter starts cycle after preset volume of
water has been softened.

Warranty
Culligan® Hi-Flo®3 water softeners are backed by a
limited 1-year warranty against defects in materials,
workmanship, and corrosion. The plastic conditioner
tank has a 5-year warranty. See printed warranty for
details.
*
Some localities have corrosive water. A softener cannot
correct this condition, so its printed warranty disclaims
liability for corrosion of plumbing lines, fixtures, or
water-using equipment. If you suspect corrosion, your
independently operated Culligan dealer has equipment
to control the problem.
*Culligan will provide a copy of warranties upon request.
The contaminants or other substances removed or reduced by
this water treatment device are not necessarily in your water.
Options
• Regeneration Flexibility—There are several choices
for regenerating a Hi-Flo
®
3 water softener to meet
your requirements. The simple, economical choice
is timeclock operation for both single and duplex
units. If water usage varies, meter operation is
available to signal regeneration immediately or
delay regeneration until a pre-set time. Duplex
meter operated units may be operated in parallel or
on an alternating basis, depending upon your needs.

1 Exchange capacities based on treating water containing 10 grains per gallon (171 mg/L) of hardness (expressed as calcium carbonate), free of color, oil, turbidity
and at a service flow rates not exceeding 20 gpm per square foot (49 m3/m2/min) of bed area. These are nominal capacities and will vary with influent water
characteristics, temperature, pressure and other factors.
2 Operation of a softener at peak flow rate for extended periods of time may result in a slight reduction of softening capacity. This is due to premature hardness
breakthrough.
NOTE: Operational, maintenance and replacement requirements are essential for this product to perform as advertised.
Specifications are shown for single models. Duplex models have two softener tanks and one brine tank system.

exhausts while the first tank is in regeneration.
¨ (Meter Initiated, Alternating Twin Unit)
A single, remote mounted volum etr ic meter shall s ignal t he sof ten ers to r egener ate on a n a lternati ng bas is after
the preset volume of water has passed through the water softener. One unit remains in a fully regenerated
stand-by condition while the other unit is in servic e. Upon exhaustion of the ser vice unit, the s tand-by un it shall
immediately be placed into serv ice and the exhauste d unit shal l be rem oved from service and the r egeneration
initiated. The tim er will activat e a m otor dr ive that will perf orm the r egeneratio n f unctio ns on the exha usted tank
and return it to the stand-by position. No exter n al alt er nat ing de vices will be accep tab le. The alternating function
