Required materials
• Chemical-resistant, powder-free gloves
To connect the source exhaust valve assembly:
Requirement: Wear clean, chemical-resistant, powder-free gloves when performing
this procedure.
1. To connect the tubing in a rear configuration, ensure that the 90-degree elbow connector
on the source exhaust valve is rotated to point toward the rear of the instrument, as shown
in the figure below.
Note: For a front configuration, see the figure "Internal source exhaust valve—front
configuration" in step 3.
2. Thread the PTFE waste tubing alongside the instrument through the two hose brackets,
from the back end toward the elbow connector.
Note:
• Routing the exhaust tubing through the hose brackets positions the tubing at a
downward gradient. Doing so prevents the pooling of solvents.
• To prevent the pooling of solvents in a front configuration, ensure that the source
exhaust tubing is positioned forward and in a downward gradient.
3. Insert the end of the tubing into the source exhaust valve elbow connector.
