1.Parts identified by the A symbol on the schematic
diagram and the parts list are critical for safety.

Use only replacement parts that have critical
characteristics recommended by the manu-
facturer.

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.
