M11 Procedure - Maintenance Facility

When cleaning the valve and associated components, it is imperative that the maintenance
be performed in a clean and contaminant free facility. Components should be placed on a lint
free cloth to prevent impurities from contaminating the valve and/or components. Hands should
be clean and free of contaminants.
Presence of any foreign contamination can cause additional valve problems after reinstallation.
All foreign contamination adhering to valve must be removed quickly using a dust/lint free cloth
and a cleaning solvent such as hexane. After cleaning valve cap and tubing, shake excess
cleaning fluid from tubes and let valve cap air dry before reassembling.
NOTICE
Do not allow polished face of valve cap to rest on any surface other than a lint free cloth.
Clean metal parts using a syringe or ultrasonic cleaner and an appropriate cleaning solution
as described in this procedure.
