Pressure Application Adjustments 

 

Use the following procedure for start-up  and adjustment of the system.  (

Note: 

In elevated 

pressure applications,  the customer should install a flow controller downstream from the 
application,  as detailed in the Installation section of this manual.) 

 

a.

 

Open the (customer installed) inlet air gate valve. 
 

 

b.

 

Adjust the (customer installed) inlet air pressure regulator until the Operating Pressure 
gage (see figure 1) shows the pressure required to deliver nitrogen at the desired flow 
rate (per Tables 3 and 4.) 
 

c.

 

Turn the flow control valve to its fully open position.
