assembly. The end of the tube which connects the vaporizer manifold assembly is not
pulled out but the other end is.
5. Flatten the negative pressure ball to remove the gas inside. Then re-install the gas
outlet switch of the negative pressure ball properly. Connect the other end of the
negative pressure ball to the pulled-out No.53 tube through 3106-06-08 adapter
connector and occlude the pulled-out tube end on the flowmeter as shown below.
