When performing any type of maintenance of NetScanner

™

System components, the

following guidelines and precautions should always be followed:

! Verify that the work area and technicians are properly grounded to prevent damage to

electronic components due to electrostatic discharge.

! Ensure that all electrical and pneumatic connections have been removed from the

module.

! Ensure that the work area is free of dust and other possible contaminants that may

affect the high tolerance machined parts (and pneumatic seals, if model has an integral

manifold).

! Care must be taken to prevent contaminants from reaching O-ring surfaces. If O-ring

surfaces require cleaning, use a lint-free applicator with acetone to remove dirt and

lightly lubricate the O-ring surface with Krytox® provided in the maintenance kit.

! Never use sharp objects to cut tubing from the bulged tubes. The tiny scratches left on

the tubes could cause leaks.

NOTE: PSI offers an optional

maintenance kit (PSI P/N

S901-0200000000) with the

lubricants included.

In the process of performing general maintenance on a module and in printed-circuit board

replacement, the following tools may be required:

! 3/32" and 5/64" Allen-head screwdrivers,

! a 3/16" hex wrench,

! a needle nose tweezers,

! a Phillips-head screwdriver,

! a small adjustable wrench,

! a tube of Krytox

lubricant (PSI P/N 42-06-KRYX),

! a spray bottle of silicone liquid lubricant (PSI P/N 41-06-Silicone).
