During this procedure, hot adhesive can come out of the Applicator
under high pressure.
Components and adhesive are hot when this procedure is being done.

:
a. Manually open the module(s).
This is done by pushing the
solenoid operator button(s)

turns. This screw is located on
the back of the filter block next
