Application
Water quality—verify that raw water hardness and iron are within limits. Note the hardness for
setting the salt dosage and recharge frequency.
Iron is a common water problem. The chemical/physical nature of iron found in natural water
supplies is exhibited in four general types: Dissolved Iron, Particulate Iron, Organic Bound Iron and
Bacterial Iron. Hardness sample kits are available through your local Culligan dealer.
Pressure - If pressure exceeds 125 psi (860 kPa), install a pressure reducing valve (see materials
checklist). On private water systems, make sure the minimum pressure (the pressure at which the
pump starts) is greater than 20 psi (140 kPa). Adjust the pressure switch if necessary.
Caution! Do not use where the water is microbiologically unsafe or with water of unknown
quality adequate disinfection before or after the unit.
Caution! The use of a pressure reducing valve may limit the flow of water in the household.
Temperature—Do not install the unit where it might freeze, or next to a water heater or furnace or
in direct sunlight. Outdoor installation is not recommended, and voids the warranty. Use the Culligan
Outdoor Gold or Medallist Series Softeners for outdoor installations. The Culligan Outdoor Gold or
Medallist Series Softeners have been certified by Underwriter's Laboratories for outdoor installation.
If installing in an outside location, you must take the steps necessary to assure the softener installation
plumbing, wiring, etc. Areas well protected from the elements (sunlight, rain, wind, heat, cold),
contamination, vandalism, etc. as when installed indoors.
Location
Space requirements—Allow 6–12 inches (15–30 cm) behind the unit for plumbing and drain
lines and 4 feet (1.3 meters) above for service access and filling the salt container.
Floor surface—Choose an area with solid, level floor free of bumps or irregularities. Bumps,
cracks, stones and other irregularities can cause the salt storage tank bottom to crack when filled with
salt and water.
Drain facilities—Choose a nearby drain that can handle the rated drain flow (floor drain, sink or
stand pipe). Refer to the Drain Line Chart, Table 3 (page 24), for maximum drain line length.
Note: Most codes require an anti-siphon device or air gap. Observe all local plumbing codes
and drain restrictions. The system and installation must comply with all state and local laws and
regulations.
Electrical facilities—A 10-foot cord and wall mount plug-in transformer are provided. The customer
should provide a receptacle, preferably one not controlled by a switch that can be turned off
accidentally. Observe local electrical codes.
Note: The softener works on 24 volt/60 Hz electrical power only. Be sure to use the included
transformer. Be sure the electrical outlet and transformer are in an inside location to protect from
moisture. Properly ground to conform with all governing codes and ordinances.
Note: PN 01020620 and PN 01018133 plug-in transformers are rated for indoor
installations only.
