Specifications for High Efficiency 1.5 Twin Water Softeners
Culligan commercial water softeners are designed to remove hardness minerals from water. In order to function properly,
some operational parameters must be followed. They include:
1. An operating water pressure between 20 and 125 psi (138-862 kPa). If water pressure is greater than 80 psi, Culligan
recommends following the IAPMO Uniform Plumbing code section 806.2 by installing a Pressure Regulating Valve
before the system. Operating on high presure for extended periods of time can increase the service frequency of re-
placement parts. If water pressure can drop below the minimum water pressure, add a booster pump to maintain a
25 psi (172 kPa) minimum operating pressure.
2. Operating temperature between 33° and 120°F or 1°–49°C.
3. Clear (non-turbid) water supplies (Less than 5 NTU).

NOTE Dimensions assume systems include an optional, standard size brine tank. The measured width in-
cludes the supplied interconnecting pipe.
NOTE Allow a minimum of 24" above the overall system height for access into the top of tank(s).
