Mix Material Flush Procedure

Standard procedure for all pumps except
polyester model 24W609
To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
lowest possible pressure. Monitor the fluid gauges
during flush operations to ensure the pumps are not
over pressurized.
NOTICE
Before flushing stop the pump at the bottom of its
stroke to keep fluid from drying on the exposed dis-
placement rod and damaging throat packings.
1. Trigger the gun to stop the pump at the bottom of its
stroke.
2. Shut off air to gun air pressure regulator (D) and the
pump air pressure regulator (H). Close the bleed
type master air valve (E).
