Cleaning Frequency Guidelines
Initially, a once a month inspection and cleaning is recommended, then based on your
experience using with the pump and fluid, extend or shorten the cleaning interval as
needed.
Cleaning frequency is determined according to the type of fluid being dispensed. For
pumps in continuous use, clean in intervals no greater than 3 x fluid pot life. For
pumps dispensing fluids stable at room temperature and that have no significant pot
life issues, the pump may be run continually without issue.

Flush Pump
The flush procedure is used primarily when underfill material needs to be purged from the
pump. The dispense tip and needle can be removed or left in place:
•
The dispense tip may be left in place or removed during the flush procedure.
•
If a disposable needle is present, remove and discard it.
•
A needle intended for reuse can remain in place on the pump as the flush procedure will
clean the needle.
To flush fluid from the pump:
1. Remove the fluid reservoir from the pump.
2. If present, remove disposable needle.
3. Install an empty syringe on the pump.
4. Fill the syringe with a suitable solvent.
5. Set the pump to purge into a purge cup or suitable container.
6. Continue to purge until all dispense fluid has been purged and only solvent is exiting the
pump.
