Materials needed
• Screwdriver, Torx T-15 (8710-1622)
Procedure
1
Vent the instrument.
2
Trace the calibration valve cable to the connector next to the
fan and disconnect it.
Loosen the collar and remove the calibration vial
3
Just loosen the collar, do not remove it.
Removing the valve with the vial installed can result in liquid
calibrant getting into the restrictor of the valve. Liquid in the
restrictor will prevent diffusion of PFTBA into the analyzer chamber
for tuning. Replace the valve if this happens.
Remove the two screws holding the valve assembly to the
4
top of the analyzer chamber. Do not lose the O-ring under it.
