SAFETY INFORMATION Read, understand, and follow all safety information contained in these instructions prior to installation and use of the CFS Series Housings. Retain these instructions for future reference. Intended Use: The CFS Series Housings are intended for use in filtering potable water in the foodservice industry and have not been evaluated for other uses. These systems are typically installed at the point-of-entry, and must be installed as specified in the installation instructions.
Procedure for Installing Filter: Your new CFS Series Housing is designed to reduce particulate matter and/or chlorine taste and odor, depending upon the cartridge used. The CFS01 and CFS02 Series filter systems come with internal shut-off valves in the filter head, eliminating the need for external valves. The CFS11 and CFS12 Series filter systems require an external shut-off valve installed before the system. All housings have either a transparent (T) housing or an opaque (S) sump.
Cartridge Replacement Instructions CAUTION To reduce the risk associated with property damage due to water leakage: • The disposable filter cartridge MUST be replaced every 6 months or at the rated capacity or if a noticeable reduction in flow rate occurs. 1. Turn off incoming water supply. IMPORTANT NOTES • For those systems with internal shut-off valves, turn the valve on the filter head to “OFF” position.
