Performance Specifications <br />Specifications for CTM Water Softeners <br />Culligan commercial water softeners are designed to remove hardness minerals from water. In order to function properly, <br />some operational parameters must be followed. They include: <br />1. An operating water pressure between 35 and 125 psi (241-862 kPa). If water pressure is greater than 80 psi, <br />Culligan recommends following the IAPMO Uniform Plumbing code section 806.2 by installing a Pressure Regulating <br />Valve before the system. Operating on high presure for extended periods of time can increase the service frequency <br />of replacement parts. If water pressure can drop below the minimum water pressure, add a booster pump or operate <br />the pilot valve using compressed air to maintain a 35 psi (241 kPa) minimum operating pressure. <br />NOTE If an air compressor is used, it must be `oil free" and set at 10 psi greater than the maximum <br />static water pressure. <br />2. Operating temperature between 40' and 120°F or 4.4°-49°C. <br />3. Clear (non -turbid) water supplies (Less than 5 NTU). <br />4. Voltage of 120V, 50/60 Hz. <br />Table 1.

The Culligan GBE Controller will not remove a tank brought on line <br />by attaining the Trip Point unless the flow is under the Trip Point amount for a 30-second period. In the event additional <br />units are not brought on line or off line when desired, simply adjust the programmed Trip Point. Refer to the revised GBE <br />Programming for Commercial Softeners and Filters (except for HFxN) Manual (P/N 01027295) for more information about <br />the Progressive Flow mode of operation. <br />'Refill flow rates based on 60 psi inlet/influent pressure and eductor combinations specified per lable 5 Q.g.,, 1,m <br />and brine refill flow control inserts specified in Table 6 qr ..fa a 1-§.
