Culligan Smart Controller HE DF 12 Installation, Operation, And Service Instructions With Parts Lists page 11

Application
Water Quality
Verify that raw water and flow rate are within limits as outlined in the specifications.
CAUTION! Do not use where the water is microbiologically unsafe or with water of unknown
quality without adequate disinfection before or after the unit.
Pressure
If pressure exceeds 125 psi (860 kPa), install a pressure reducing valve (see materials checklist). On private water sys-
tems, 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! 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 HE filter for outdoor installations. The Culligan Out-
door HE filter has been certified by Underwriter's Laboratories for outdoor installation. If installing in an outside location,
you must take the steps necessary to assure the filter, installation plumbing, wiring, etc. are as 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 the unit for
service access.
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 on page 18, for maximum drain line length.
NOTE Most codes require an anti-siphon device or airgap. 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 P/N 01012956 and P/N 01018133 plug-in transformer are rated for indoor installations only.
NOTE The filter works on 24 Volt/60 Hz 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.
