Cleaning
Flush the unit before taking it apart for cleaning. Flush
the system with an over-sized container of cleaning
solution around the ram plate. Run the pump at low
speed and circulate the cleaning solution through the
system.
Flushing Safety
To reduce the risk of fluid injection injury, static sparking,
or splashing, follow the Pressure Relief Procedure (page
9) and remove the spray tip (spray guns or spray valves
only) before flushing. Hold a metal part of the gun firmly
to the side of a metal pail and use the lowest possible
fluid pressure during flushing.
Remove the Inflatable Seal
The inflatable seal must be removed from the bottom of
the ram plate. The bottom lip diameter is smaller than
the top. Do not use sharp objects to remove the
seal. Clean the seal and the ram plate.
1. Disconnect the air tube (A) from the seal fitting. The
fitting must be removed to allow passage of the
stem through the plate access tunnel.

2. On the side opposite the stem and starting with the
top edge, peel the seal downward. The bottom side
of the plate has a smaller diameter than the top to
facilitate easy removal and installation.

3. Continue peeling the top edge of the seal along the
diameter of the plate. Note that the top edge is
twisted downward. Once the seal is loose, gently
pull the stem from the tunnel.
