Water lters should be replaced at a minimum every three months for the 1.0 micron and 0.4 micron lters
and every six months for the 0.1 micron lter. If the water pressure drops below 40 PSI or the difference
between the gauges is greater than 5 PSI the corresponding lter needs to be replaced.
The following conditions must be met before changing a lter:
• No endoscope reprocessing cycles are running.
• No water line disinfection procedure is running.
• The inlet water supply is turned off.
You will need the following materials:
• A container to catch water.
• A lter bowl wrench.
• The necessary lter cartridges (see Table 1) (See Appendix B for replacement part numbers).
