There are two ways to solve this fit issue. One is to cut and grind out the top part of the guide on the original Millipore housing. To do that you need to remove the plug on the bottom of the housing and then use a drill or cutting wheel that is mounted on a drill extension. The pictures below show a housing before and after modification.<\/p>\n<p>\u00a0<\/p>\n\n\n<figure class=\"wp-block-image size-large\"><a

If you have the original Millipore housing on your 12\u201d deionizer cartridge then I recommend that you inspect it to see whether the guide on the bottom has been cut down or not.<span style=\"mso-spacerun: yes;\">&nbsp; <\/span>If not, you should cut it down or replace the housing.<span style=\"mso-spacerun: yes;\"> &nbsp; <\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"mso-spacerun: yes;\">I<\/span>f the deionizer is ruptured then the entire cooling system (reservoir, pump, water lines and source) needs to be inspected and flushed out.This problem is an issue only with the 12&#8243;

deionizer cartridge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not sure if you need to replace your deionizer cartridge?<span style=\"mso-spacerun: yes;\">&nbsp; <\/span>Just run up the high voltage on your X-ray source to 15kV but do not set an power to the X-ray source.<span style=\"mso-spacerun: yes;\">&nbsp;&nbsp; <\/span>Observe the emission current reading on the HV supply.<span style=\"mso-spacerun: yes;\">&nbsp; <\/span>If the deionizer is good the reading will be 1-2 mA.<span style=\"mso-spacerun: yes;\">&nbsp; <\/span>Once the leakage current gets up to 3-4 mA at 15kV you should plan on replacing the deionizer cartridge and particle filter soon.<span style=\"mso-spacerun: yes;\">&nbsp; <\/span>If the leakage current at 15kV is 5 mA or higher you should replace the deionizer and particle filter and also flush out the water with new distilled water from a grocery store.<span style=\"mso-spacerun: yes;\">&nbsp;
