7. MOUNTING INSTRUCTIONS

7.1. Location

It does not matter whether the Micro Ports are installed vertically or horizontally. Note the following when determining the position of the Micro Ports:

• Securegoodflowofproductinfrontoftheseptum• Avoiddeadspaceattheproductsideoftheseptum• AssamplingisamanualoperationsecuresufficientroomfortheoperatoraroundtheMicro

Port.

7.2. Before weldingTheMicroPortbase(housing)istheitemtobewelded.Thecap/plug,theseptumandallothercomponents must be removed from the base before welding, as heat from the welding process will otherwise damage them.

7.3. After weldingThebaseisweldedtothetankorpipefollowingtheinstructionsinchapter8.Oncethebasehascooledofftheothercomponentsmustbefittedtothebase,asfollows:For the Micro Port:

10. MAINTENANCEThe regular maintenance consists of the following:

• Replacing septum (only Micro Port)• Replacingwick(onlyMicroPort)• Replacing the testimonial foil and septum (only Multi Micro Port)

Occasional maintenance consists of replacing worn or damaged o-rings.

The patented membrane design is an essential part of the hygienic design of the KEOFITT sampling valves

It allows for optimal exposure to CIP and SIP media while also integrating the capacity to remove the membrane from the valve body without the use of tools

FEATURES

LIFE TIMEThe MicroPort membrane can be pierced up to 20 times and can withstand 6 bar(g) maximum pressure. Please note with higher pressure each membrane can sustain fewer piercings. The risk of cross contamination increases with number of piercings. SIP/CIP temp. max.:Process pressure:
