Solenoid Valve O-Ring Replacement 
 
The following is a step-by-step procedure to replace the internal solenoid valve O-rings in a 
Model 9816 Intelligent Pressure Scanner. The modules contain two internal solenoid valves. 
 
(1) 
Disassemble the module as described in Section 5.1.2. 
 
 
(2) 
Remove the two (2) Allen-head screws that secure 
the solenoid manifold to the module top guide rail.  
Carefully move the solenoid manifold assembly to 
one side for easier access.  Be careful not to 
crimp the attached nylon tubing.
