Warranty

The Soft-Minder Twin Plus Water Softeners by Culligan are backed by a limited 1-year warranty against defects in material, workmanship, and corrosion. The plastic conditioner tank has a 5-year warranty. Tripl-Hull steel tanks have a lifetime warranty. See the 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.

1 Exchange capacities based on treating water containing 10 grains per gallon of hardness (expressed as calcium carbonate), free of color, oil, turbidity and at a service flow rates not exceeding 20 gpm per square foot of bed area. These are nominal capacities and will vary with influent water characteristics, temperature, pressure and other factors. 2 The service flow rate is based on one tank regenerating while the other tank is delivering soft water. Performance is slightly improved when regeneration is complete and the non-service tank is in standby. 3 It is recommended that the frequency of regeneration be limited to once every eight hours. 4 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.

EQUIPMENT SPECIFICATIONS SOFTENER TANK(S) Each system shall include two (2) tanks. Each softener tank shall be _____ inches in diameter. The sideshell height shall be _____ inches, sufficient to allow for proper freeboard space above the resin bed for adequate expansion of the resin during backwashing.
4.1.0 Tank Construction (Tripl-Hull vessel) Tank(s) shall be electrical welded pressure vessel quality low carbon steel construction rated for 100 psig working pressure. (Fiberglass vessel) Tank(s) shall be manufactured of polyester reinforced by a continuous roving glass filament overwrap. The top opening will be 4 threaded and the tank bottom will be supported on a molded structural base. 4.1.1 Tank(s) will be of the Culligan Tripl-Hull construction. (Tripl-Hull vessel ONLY) 4.1.2 Access Openings Each tank will be equipped with openings for mineral filling and periodic inspection. (Tripl-Hull vessel ONLY) 4.1.3 Tank Finish Exterior The tank exterior will be protected by a molded plastic jacket for corrosion resistance. The jacket will also act as an insulator to minimize condensation on the surface of the tank. (Tripl-Hull vessel ONLY) 4.1.4 Tank Finish Interior The tank interior will consist of a 20 mil thick vinyl bag liner, hermetically sealed within the steel tank to protect against internal corrosion. 4.2 INTERNAL DISTRIBUTION

4.2.1 The upper distribution system shall be of the single point diffuser type to dispense water laterally to avoid channeling within the resin bed.
Culligan Soft-Minder Twin Softener Engineers Specification

4.2.2 The lower distribution system shall be of the single point distributor type, constructed of PVC pipe and a fine slotted strainer to provide even flow distribution through the resin bed. The distribution system shall be embedded in a subfill of washed inorganic material to support the resin bed. 4.3 MAIN OPERATING VALVE The main operating valve shall be of a top mount design constructed of all brass and sized with <1.0/1.5> inch NPT inlet and outlet water pipe connections. The main operating valve will be of the motor driven, mechanically activated design with six (6) positions to accomplish the regeneration steps of backwash, brine draw/rinse, fast rinse, brine refill and stand-by, in addition to the service position. The main operating valve shall incorporate self adjusting flow regulators to control the rate of flow and prevent resin loss during backwash regardless of system pressure fluctuations between 30 and 100 psi. The main operating valve will be fitted with a fixed orifice eductor. 4.4 CONTROLS The main operating valve will be controlled by a single electrically controlled timer to control the regeneration and to alternate the tank in service. The timer will activate a motor drive which will shift the stand-by tank into the service position, perform the regeneration functions on the exhausted tank and return it to the stand-by position. The timer will permit individual adjustment of the backwash, brine-rinse, fast rinse and brine refill cycles. No external alternating devices will be acceptable. The alternating function must be contained in the sequencing controller. Simultaneous regenerations shall not be possible. 4.4.1 Flow Meter The main operating valve will include one (1) mechanical turbine-type meter on the outlet side of the water softener. The meter will be directly connected to the cycle timer by a cable. The meter provided shall be the same size as the outlet of the softener. The meter provided shall be functional within the flow range of 0.7 to 40 gpm. The operating temperature/pressure range of the meter shall be 34F - 110F at 120 psi max. 4.5 EXCHANGE RESIN The ion exchange resin shall be virgin high capacity standard mesh of sulfonated polystyrene type stable over the entire pH range with good resistance to bead fracture from attrition or osmotic shock. Each cubic foot of resin will be capable of removing 30,000 grains of hardness as calcium carbonate when regenerated with 15 lbs. of salt. The resin shall be solid, of the proper particle size of 20-50 mesh, U.S. standard screen and will contain no agglomerates, shells, plates or other shapes that might interfere with the normal function of the water softener. The resin shall be manufactured to comply with the food additive regulation 21 CFR 173.25 as set forth by the USFDA. The system shall include _____ cubic feet of exchange resin per vessel and a total of _____ cubic feet of resin for the system. 4.6 BRINE SYSTEM Provide a complete brine system consisting of a plastic tank, salt platform, salt dosage brine well, an automatic brine valve and all necessary fittings for operation with the water softening system. The system shall consist of a combined brine measuring and salt storage tank with salt platform. The tank will be sized ____ inches x _____ inches; the system will include a total of _____ brine tank(s). The brine tank will be equipped with a float operated non-corrosive field serviceable brine float valve for automatic control of brine withdrawal and fresh water refill.

Page 3

The brine valve will automatically open to admit brine to the resin tank during eduction and close automatically providing positive shut-off to prevent air from entering the system. The brine valve will also regulate the flow of soft water into the brine tank during refill. The brine valve works with the timed fill feature of the main operating valve controls to admit the correct volume of fresh water to the brine tank in accordance with the salt dosage setting on the controls. The brine valve will include a float operated safety shut-off valve as a back up to the timed refill from the main operating valve control to prevent brine tank overflow. 4.7 4.7.1 4.7.2 4.7.3 4.7.4 5.0 ACCESSORIES (All Optional selections) Water test kits for hardness tests will be supplied. Pressure Gauges for hard water inlet and soft water outlet. Sampling Cocks for hard water inlet. Vacuum Breaker for protecting Fiberglass tanks from vacuum. INSTRUCTIONS _____ complete sets of installation, operating and maintenance manuals shall be provided. FIELD SERVICE The services of a factory authorized service representative can be made available to supervise, inspect and provide operator training as required for initial start-up and system operation. Contact your local Culligan dealer for service rates and scheduling. WARRANTY A single written warranty must be provided from the manufacturer of the water softener system covering workmanship and materials.
