7. Apply soapy water to the seal in the Lower Valve Body (6986) and look for
bubbling that would imply a leak (do not point the resin outlet directly at yourself). It
is acceptable to have a small leak here.
8. Operate the IVX3 to the Purge position; the indicator/gauge should now show
pressure. Once again apply soapy water to the seal and check for leaks. There
should not be any leaks here if the valve is in good condition.
9. Apply soapy water to the fluid section where the Lower Valve Body (6986) and
Upper Valve Body (6985) join and check for leaks.
10. Apply soapy water to the fluid section where the Upper Valve Body (6985) and
Actuator Cylinder (6981) join and check for leaks, particularly at the isolation
channel. A leak here could indicate a problem with the Valve Bush (7052), or fitted
O-rings.
11. Point the IVX3 away from yourself and operate to the Inject position, air should
vent out of the resin Inject port. Close the valve.
12. Operate the IVX3 between the Closed-Inject-Purge-Closed positions a number of
times and ensure the shaft is moving freely.
NOTE: When testing is complete, residual pressure can remain in the hoses
connected to the Resin inlet and Purge outlet; take care when dis-connecting the
valve.
