8. If the dispense device cannot be actuated from the
control center, refer to F
IG. 16 and perform the fol-
lowing steps to open the dispense valve and relieve
fluid pressure:
a. Manually actuate the plunger on the solenoid,
that opens the dispense valve to relieve fluid
pressure. Refer to F
IG. 16.
b. Continue actuating the plunger until all pressure
is purged from the system between the needle
and dispense valve before proceeding to the
next step.
9. Shut off power and air to the fluid supply system.

If you have followed the previous steps and still sus-
pect that a valve, hose, or dispense nozzle is clogged
or that pressure has not been fully relieved, very slowly
remove the dispense tip, clean the orifice, and con-
tinue relieving pressure.
If this does not remove the obstruction, very slowly
loosen the hose end coupling and relieve pressure
gradually, then loosen the coupling completely. Clear
the valves or hose. Do not pressurize the system until
the blockage is cleared.
