Visual Inspection Risk of electric shock. Disconnect all supplies before any visual inspection. o Verify condition of heating elements. o Heating element must be clean and free of dust or lint. o Open Coil: Carefully verify that there is no dust accumulation. Any dust of lint accumulation can lead to fire hazard. o Verify any indication of overheating conditions (discoloration) as well as any trace of oxidation (rust). Electrical Inspection Risk of electric shock. Disconnect all supplies before any electrical inspection. o Verify that electrical connections are correct and properly tightened. o Verify the condition of fuses. o Verify resistance of each circuit against ground. o Verify correct operation of contactor(s). o If necessary, electrical components must be replaced only with identical origin components. Filter Maintenance Risk of electric shock. Disconnect all supplies before removing and inspecting the filter. o CMU is equipped with a filter that must be washed at regular intervals. o Check the filter after two months of operation. o To take out the filter, remove the access cover by disconnecting the two screws. o If the filter is extremely dirty, increase the frequency of inspections. o Ensure that the filter is dry before replacing it. ! Warning, the CMU must always have a filter installed at this location even if an auxiliary filter is used.
