CAUTION
1.Parts identified by theAsymbol on the schematic
diagram and the parts list are critical for safety.
Use only replacement parts that have critical charac-
teristics recommended by the manufacturer.
2. Make leakage-current or resistance measurements
to determine that exposed parts are acceptably in-
sulated from the supply circuit before returning the
appliance to the customer.
