counterclockwise to vent any entrapped air . Tightly close plug after all air is evacuated .
9 . Slowly open the outlet block valve (A) to allow pressurized flow through the system.
10 . Verify the regulator/valve assembly's outlet pressure (G) to determine if there is any
leakage . If there is any leakage, remove the 56-2XXX Series assembly for inspection and
repair . If no leakage occurs move on to Step 11 .
11 . Check the Bleed Plug (D) for any sign of liquid leakage. If leakage occurs remove
56 Series regulator for inspection and repair . If no leakage occurs move on to step 12 .
12 . Verify and record flow rate and pressure over time.
13 . Adjust valve (B) by turning the hand knob to the desired orifice size until desired flow
rate is achieved .
14 . Following any adjustment to valve (B), verify and record flow rate and pressure
over time .
