Sanitation/ Sterilization*
May be steam sterilized in line 100 times for 30 minutes, up to 228 °F, or hot water sanitized 50 times for 30 minutes, up to 180 °F - except for CVBW, which may be hot water sanitized 30 times for 30 minutes up to 180 °F
Hot water sanitized at 180 °F for 30 minutes
Installation • Assure that the housing, pressure gauges, valves, gaskets and o-rings are in good working order (housing o-rings should be replaced on a regular basis). • Carefully remove the cartridge from the packaging material and inspect. Use caution when opening the filter bag – scissors are recommended. Each filter cartridge is stamped with the grade and comes with a quality certificate in the box. Verify that the correct filter is being installed for the intended application. • Wet the o-rings with water and install into the housing, being careful not to roll the o-rings upon installation. • Run ambient temperature water* through cartridges under a little back pressure to fully wet out the filter media. Sterilization & Cleaning • MilliporeSigma recommends the use of hot water* (180 °F for 30 minutes) for sterilization of filters and filter housings (time period starts when the housing outlet comes to temperature). Once the
proper temperature is reached, take care to use only a low hot water flow and low differential pressure. • Each hot water cycle should always be preceded and followed by an ambient water* rinse cycle. • If hot water is not available, the filters are compatible with a wide range of sanitation chemicals. Please consult your Gusmer representative for specific information. • Ensure that filter housings remain vented during cleaning and sterilization. • It is recommended to start each cleaning cycle with at least 5 minutes of cold water flow. Temperature should then be gradually increased to its final cleaning temperature (typically 180 °F). A longer warm water rinse is beneficial to cleaning. Filters should never be contacted with a temperature above 135 °F without first rinsing with cold/warm water* to acheive maximum throughput. • Some filters can be backflushed. Please consult your Gusmer representative for specific information. • Avoid pressure shocks and water hammer especially during cleaning/sanitation with hot fluids.
*Use filtered, softened water for wetting, cleaning, and sterilization to avoid fouling the cartridges.
