    DIAGNOSTICSAND TROUBLESHOOTING FAULTS AND This chapter assists the user to identify and correct possible faults POSSIBLE that can occur during the CFW-10 operation. Also instructions about CAUSES required periodical inspections and cleaning procedures are also provided. When a fault is detected, the inverter is disabled and the fault code is displayed on the readout in EXX form, where XX is the actual fault code.
