M11 Procedure - Valve Cap Cleaning And Re-Assembly - Siemens Maxum II PD PA AP Service Manual

Valves
4.6 Model 11 Valve
It is possible and often better to use an appropriate detergent, such as Alconox® for cleaning
instead of solvent. However, after cleaning with a detergent, it is necessary to rinse the part
thoroughly with deionized water (distilled water is also acceptable) in order to remove detergent
residue. All water must then be removed by blowing with clean air or shaking. Components
must be completely dry before reassembling.

If solvent becomes contaminated during performance of the following cleaning steps, it must
be replaced with a clean supply from a clean beaker.

1. (For Model 11 Valve) – Clean valve cap (3) while disassembled using a syringe and
appropriate solvent. Clean each port and attached tubing on the valve cap by flushing
solvent back and forth through each port while cap is immersed in a beaker of solvent.
2. (For the Model 11 LDV Valve) - Clean the valve cap (3) while disassembled and visually
verify that ports are clear. Use of an ultrasonic cleaner and an appropriate cleaning solution
is recommended.
