Preparation The success of the installation will depend to a great extent on advance planning and preparation. Careful attention to the unit's location, accessibility to electrical and drain facili- ties, and the availability of the proper tools will ensure a pro- fessional looking installation. Of utmost importance is the assurance that the conditioner has been properly applied and meets all specifications. APPLICATION Essential to correct application is a complete analysis of water to be treated. Culligan extends to its customers, through its dealers, a water analysis service. Compare specified water limitations in Table 1 with the water analysis. Contact the Culligan factory immediately if any discrepancies are found. In addition, the unit is designed to be operated within certain pressure and temperature limitations. Hardness Hardness is a term which describes the material dissolved in the water which forms scale in pipes and water heaters, and causes greying of laundry, just to name a few. The softeners will perform best when total hardness is less than the maximum limit specified. Iron Iron, though not always visible when water is drawn, can cause reddish staining of fixtures and clothing, and even a dry metallic taste in drinking water. It also causes hot bever- ages, such as coffee and tea, to turn a murky, black color. Excessive amounts of iron and iron in different forms may require additional treatment. Pressure The conditioner is designed to operate within a pressure range of 30 to 100 psi (210-690 kPa). Pressure below 30 psi (210 kPa) may cause the unit to perform and recharge inefficiently, while pressures above 100 psi (690 kPa) can cause damage 6 / HI-FLO® 2 WATER SOFTENER and noisy operation of the control valve. Low pressure is generally not a problem with municipal water supplies, although some adjustment of a well pump system may be required on private supplies. Although uncommon, some municipal supplies may exceed the high pressure limit. A pressure reducing valve should be installed if such pressures are encountered. Keep in mind, also, that some municipal supplies have higher pressures during nighttime hours.

The iron limit for Aqua -Sensor device operation is 2 ppm, and for Hi-Velocityrm Cullex® (PV -135B) is 0.5 mg/L, even if a CIC system is used. Pressure Drop Whenever water is flowing a certain amount of pressure is lost due to the resistance from pipe, fittings, and appliances connected to the water supply. The amount of pressure drop encountered depends on how fast the water is flowing and how much resistance it meets. The amount of pressure avail- able at a tap is also determined by its height above the source supply. For example, if water pressure in the basement is 50 psi (345 kPa), it will be about 45 psi (3 10 kPa) on the ground floor, and about 40 psi (276 kPa) on the second floor, or a
