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).
