CAUTION
1. Parts identified by the 4\ symbol on the schematic diagram and the parts list are critical for safety.
Use only replacement parts that have critical characteristics recommended by the manufacturer.
2.
Make
leakage-current
or
resistance
measurements
to
determine
that
exposed
parts
are
acceptably
insulated
from
the
supply
circuit
before
returning
the appliance
to
the
customer.
