User Guide (12. Fan Cleaning)
Now, let me explain about how to clean the fan on Smart Ceramic Coffee Roaster, CEROFFEE CRF-800. If heavy coffee buildup or oil residue accumulate after several months of steady use, it could result in abnormal sound of the fan or poor smoke exhaustion. Therefore, keep the fan clean to ensure proper operation.     Several tools are required for disassembling and cleaning; hex wrench (2.5 / 3.0 / 4.0 mm) and a screwdriver to remove and assemble the fan, brush to clean fan (We recommend iron brush or tooth brush when cleaning fan.)     Make sure the device is fully cooled before cleaning and replacement. First, power switch off and unplug power cord. And then remove hopper and bean entrance hole cover. Remove top cover by removing 6 fixing bolts with 2.5 mm hex wrench. Remove inner top cover by removing 6 fixing bolts with 3.0 mm hex wrench. And then remove one side cover by removing 4 fixing bolts with 4.0 mm hex wrench. Check positions of fan, flexible hose connected to fan, connection cable to activate fan and fixing bolts and order for disassembling. Remove flexible hose after loosening bolt of hose band with a screwdriver. And then separate cable terminal of fan connected with PCB board by pressing it with fingers. Pull out the separate cable thoroughly. And then remove 1 of 3 fixing bolts with a screwdriver and the remaining 2 fixing bolts behind the fan with the screwdriver. Raise and take the fan out to the side.     To separate the fan, connection cable and flexible hose are being connected. Clean up grease spatters from the fan blade with iron brush or tooth brush.
