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.
