Internal, source exhaust valve—rear configuration
3.15.1 Removing the source exhaust valve
Before removing the source exhaust valve, ensure that a replacement valve (part number
289010426) is available to install.
Required material:
•
Chemical-resistant, powder-free gloves
•
5-mm Allen wrench
To remove the source exhaust valve:
1.
If tubing is in a rear configuration, disconnect the source exhaust tubing, and rotate the
elbow connector to clear the path for removing the source exhaust valve from the
enclosure.
2.
Unscrew and remove the four retaining screws from the valve grip panel using the 5-mm
Allen wrench.
3.
Hold the grip panel, and pull to slide the valve out of the enclosure.
Tip:
If the source exhaust valve does not immediately release from the enclosure chamber,
examine it for corrosion, waste build-up, or other blockage. If possible, remove any visible
obstruction, and apply reasonable force to release the valve from the enclosure.
Requirement:
Wear clean, chemical-resistant, powder-free gloves when connecting the
source exhaust valve assembly.
