Connecting the Calibration Gas Cylinder to the Dock(s)
Figure 7. Manifold for eight docks
3. Each dock is delivered with a 24" piece of tubing with a white quick
disconnect fitting, which is normally used to connect a single gas
cylinder directly to a single dock. Connect the white quick disconnect
fittings to the GAS ports on the docks and connect the open ends
to the manifold's open T-fittings.
At this point, tubing should run from each dock's GAS port to the T-fittings.
There should be no open T-fittings in the procedure, but there should be
one piece of open tubing on the elbow fitting.
4. Connect the open piece of tubing on the elbow fitting to the Demand
Flow Regulator.
