Flushing
• Flush before changing fluids, before fluid can dry
in the equipment, at the end of the day, before
storing, and before repairing equipment.
1. Turn OFF (O) the ES On-Off switch. Wait 30
seconds for the voltage to bleed off.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a non-flammable solvent that is
compatible with the fluid being dispensed and the
equipment wetted parts.
2. Discharge the system voltage. See Fluid Voltage
Discharge and Grounding Procedure, page 25.
To reduce the risk of fire, explosion, or electric
shock, turn OFF (O) the ES On-Off switch before

• FM, FMc Approved:
Material does not sustain burning in accordance
with the Standard Test Method for Sustained
Burning of Liquid Mixtures, ASTM D4206.
• CE-EN 50059 Compliant:
Materials which cannot be ignited, in any mixture
with air, by an energy source of less than 500mJ.
5. Change the fluid source to non-flammable
