TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked
Z
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.
●
Meter impedance should be equivalent to 1500 ohms
shunted by 0.15µF.
●
Leakage current must not exceed 0.5mA.
●
Be sure to test for leakage with the AC plug in both
polarities.
WARNING: CHEMICAL CONTENT NOTICE!
T
he solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly
other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON
WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to
solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling
food.

Among some types of lead free solder currently available, it is
recommended to use one of the following types for the repair
work.
• Sn + Ag + Cu (tin + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
1. 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.
2. If lead solder must be used, be sure to remove lead free solder
from each terminal section of the parts to be replaced and
from the area around it completely before soldering, or make
sure that the lead free solder and lead solder melt together
fully.
