6.4.2 Cleaning the wash bucket
Over time, dissolved resin accumulates on the walls of the wash bucket. Periodically, while
replacing the solvent, clean out the wash bucket to remove these resin deposits. Rinse the
wash bucket with fresh solvent and wipe with a paper towel.
Required supplies:
• 2.5 mm hex driver
• 43 L (11.4 US gal) of fresh solvent (IPA, TPM, or water)
• Electric siphon pump, included with the Form Wash L
• Empty container, suitable for storing up to 37.9 L (10 US gal) of solvent
• Non-reactive nitrile gloves
• Safety glasses
Follow these steps to transfer solvent from the Form Wash L into a chemically-resistant
container that is safely designated for highly-resin-concentrated solvent and to refill the wash
bucket with fresh solvent.
To clean the wash bucket:
1. Empty the wash bucket and remove it from the Form Wash L. Refer to section 6.4.1
Replacing solvent for detailed instructions.
2. There are two circular impellers located at the bottom of the wash bucket. Using a 2.5 mm
hex driver, loosen and remove the screw holding each impeller in place. Set the screws
and impellers aside.
3. Inspect the bearing underneath the impellers and the bottom surface of the impellers for signs of
wear. Visible wear on either surface is a sign that the impeller and bearing should be replaced.
4. Rinse the wash bucket and solvent monitor with IPA or water and wipe with a paper towel.
5. Reseat the two impellers in the wash bucket. Thread one screw into each of the impellers.
Using a 2.5 mm hex driver, tighten the impeller screws until finger tight.
6. Reinstall the wash bucket and fill it with solvent. Refer to section 6.4.1 Replacing solvent
for detailed instructions.
