DAIR- 4.0.0 ISOLATE VALVE #39

  

If Valve #39 is sticking open target Deaeration Pressure CANNOT be achieved:   

a)  Per the Figures above AND right locate  

Valve #39 on the BOTTOM of the 
hydrochamber.  

b)  Figure right, clamp Valve #39’s clear 

tubing at the location seen.

 

c)  Can 

[PUMP RATE]

 now be adjusted to 

achieve

 

target pressures? 

Yes 

Target pressures achieved! See procedure number 

DAIR- 4.0.1

 (page 501). 

No  Pressures CANNOT be achieved! See procedure number
