Performance Specifications
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:
• An operating pressure of water or air between 30 and 100 psi. If pressure is greater, a pressure regulating valve
should be installed ahead of the system. If pressure is lower, additional equipment will be required to maintain a 30
psi minimum operating pressure.
• Operating temperature between 40° and 120°F or 4.4° to 48° C.
• Clear (non-turbid) water supplies ( Less than 5 NTU )
