Flushing Procedure

To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing fluid, always flush at the lowest
possible pressure.
• Flush before changing colors, before fluid can dry in
the equipment, at the end of the day, before storing,
and before repairing equipment.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
