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.
