I TO SERVICE PERSONNEL

1. Critical Components information

Components having special characteristics are marked A: and
must be replaced with parts having specifications equal to
those originally installed,

2. Leakage Current Measurement (For 120V Models Only)

When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits

0 Meter impedance should be equivalent to fSOO ohms shunted
by O.f5 uF,

For U model

About lead free solder/fifiEHVjIEDLT

All of the P,C.B.s installed in this unit and solder joints are
soldered using the lead free solder,

Among some types of lead free solder currently available,
it is recommended to use one of the following types for
the repair work,

0 Sn + Ag + Cu (tin + silver + copper)

I Sn + Cu (tin + copper)

0 Sn + Zn + Bi (tin + zinc + bismuth)

Cautlon:

As the melting point temperature of the lead free solder is
about 30° C to 40° C (50° F to 70° F) higher than that of
the lead solder, be sure to use a soldering iron suitable to
each solder.
