Some geometries will prevent the isopropyl from reaching all the liquid resin. These geometrieswill hold the air that gets trapped when the isopropyl rises to the print. To completely clean theprint, remove the print from the Build Table and place it on the basket in the B9Clean and startanother wash cycle.7.7.8 Ensure the printed part is dry and free of surface resin. It is recommended to use compressedair to dry pieces prior to Curing if necessary.7.8 B9Clean Cleaning Procedure7.8.1 Unplug the barrel jack from the back of the unit.7.8.2 Remove container assembly from the base.7.8.3 Inspect base for any resin. Clean with a cloth and isopropyl alcohol while observing personalprotective measures (see chapt. 2.5).7.8.4 Remove Lid and Inner Assembly container and set aside.7.8.5 Remove all Isopropanol alcohol from the container.7.8.6 Clean the inner and outer container surfaces with a clean cloth and isopropanol alcohol.7.8.7 Inspect inner container bottom gasket to assure it is not damaged, replace if necessary.7.8.8 Do not discard the stir bar and the drain plugs.8 Safety8.1 Isopropyl Alcohol DrainingTo ensure that the 3D printed parts loaded in the B9Clean do not soak in isopropyl alcohol longer than thespecified cleaning cycle duration, the unit will automatically drain the inner container of isopropyl alcoholin the following situations.• A cleaning cycle completes• The Start/Stop button is pressed during a cleaning cycle• The B9Clean loses power8.2 Isopropyl Alcohol ContainmentWhen a cleaning cycle is not in progress, all isopropyl alcohol loaded in the B9Clean is stored in the outercontainer. The inner container creates a seal when placed inside the outer container, isolating theisopropyl alcohol from outside interference or contamination.DO NOT USE Acetone in the B9Clean. Acetone will rapidly destroy acrylic material of containers andpump. Warranty is void with even single use of Acetone.FLAMMABLEThough the B9Clean’s design reduces risk by separating the isopropyl alcohol in the outer container,isopropyl alcohol is still highly flammable in both liquid and vapor states.Read the safety information in Section 2.5 before handling isopropyl alcohol.9 Maintenance, Care and Cleaning9.1.1 Unit CleaningThe components of the unit that come into contact with isopropyl alcohol can be cleaned with water toremove uncured resin residue.NOTEEnsure that all water completely dries before refilling container and operating the B9Clean.
