Servicing 

Sample/Ref Valve and Ext/Int Valve Replacement 

Thermo Scientific 

146iQ Instruction Manual     

7-57

 

6.

 

Pull sample/reference valve upwards away from bracket. 

7.

 

Unfasten external/internal valve from fitting. 

8.

 

Replace desired valve with same fitting orientation related to the 
markings on the valve (COM, NC, NO). Reassemble in reverse order. 

Note  

All National Pipe Thread fittings require PTFE tape for sealing. 

Remove the existing PTFE tape and apply new. Wrap PTFE tape in the 
same direction of the thread spiral. Wrap around approximate two times 
around depending on the thickness of the PTFE tape. Make sure PTFE 
tape does not overhang the first thread (the lead in thread).
