routine maintenance of assembly components should be in accordance
with a good quality assurance plan.
In general, it is recommended that the inlet assemblies be cleaned on
a quarterly interval with mild soap solution, a thorough rinsing, and
dried with a lint free cloth. If any impaction surfaces require impactor
grease, it should be applied prior to reassembly. Furthermore, a general
inspection, and replacement as necessary, of o-rings should be done.
Equipment Damage Some internal components can be damaged by
small amounts of static electricity. A properly grounded antistatic wrist
strap must be worn while handling any internal component. For more
information about appropriate safety precautions, see the "Servicing"
