9. Repeat steps 3 through 5 as shown below. If the vaporizer manifold assembly is leaky,
one or several rubber plain washers and seal of the vaporizer manifold assembly or its
contacted mechanical surface are damaged. Handle this problem as described in the
troubleshooting table.
II Ensure that the vaporizer manifold assembly with vaporizer mounted (mentioned in āIā)
is not leaky and perform the following operations.
1. Remove the vaporizer and mount the vaporizer manifold test fixture onto the
connector of the vaporizer manifold assembly (remove the seal between the connector
and the vaporizer when mounting the test fixture), as shown below.
2. Pull out No.25 PU tube which connects the float flowmeter to the vaporizer manifold
assembly. The end of the tube which connects the vaporizer manifold assembly is
pulled out but the other end is not.
3. Occlude the pulled-out tube end on the vaporizer manifold assembly by using
3126-06-00 tube plug.
