Purging the DispenseJet
To purge the Fluid Line:
1. Obtain a solvent (such as Isopropyl Alcohol) that is recommended for the fluid.

NOTE If unsure, contact your material supplier for recommended solvents and always
review the MSDS for the solvent and fluid data and Protective Personal Equipment
recommendations.
2. Using the selected solvent instead of the flux fluid, follow the “Draining the Fluid Lines”
instructions in the Operation section.
3. Select
PURGE from the Fluidmove software to purge the solvent from the nozzle assembly.
Complete Cleaning
Typically, complete cleaning is performed on a bi-monthly or quarterly basis. However, the cleaning schedule
may vary depending on your application and production environment.
The following steps are necessary when performing a complete cleaning:
• Remove the DispenseJet from the dispensing system
• Disassemble the DispenseJet
• Inspect and clean
• Reassemble and reinstall the DispenseJet
Tools and Material Needed
The following tools and materials are needed:
• Adjustment and assembly tools
• Cleaning tools
• Air gun
• O-ring lubricant
• Conductive grease
Removing the DispenseJet from the Dispensing System
The instructions assume that the co-axial air solenoid valve and co-axial air nozzle are installed.
CAUTION! Do not subject the electrical cables to stress during the disassembly. Damaged
cables cannot be replaced separately and can only be replaced with the next higher
assembly.
To remove the DispenseJet:
1. Power up the dispensing system.
2. Purge any remaining fluid from the reservoir.
a. Use the position controls to move the DispenseJet so it is directly over an open purge station
(or click on
PURGE from the Fluidmove software) to purge the fluid from the fluid lines. If
necessary, refer to the Fluidmove User Guide for instructions.
b. Manually activate the solenoid valve by pressing the push-button underneath the solenoid
valve to flush out all fluid in the fluid system, lines, syringe, or reservoir.
