3.16.1 Removing the source exhaust valve
Before removing the source exhaust valve, ensure that a replacement valve (289010426) is
available to install.
Required materials
• Chemical-resistant, powder-free gloves
• 5-mm hex wrench
To remove the source exhaust valve:
Requirement: Wear clean, chemical-resistant, powder-free gloves when performing
this procedure.
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 4 retaining screws from the valve grip panel using the 5-mm hex
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 buildup, or other blockage. If possible, remove
any visible obstruction and apply reasonable force to release the valve from the enclosure.
