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.
1. Critical Components Information
Components having special characteristics are marked
⚠
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 0.15 μF.
For U model
“CAUTION”
“F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 5A, 125V
FUSE.”
For C model
CAUTION
F1: REPLACE WITH SAME TYPE 5A, 125V FUSE.
ATTENTION
F1: UTILISER UN FUSIBLE DE RECHANGE DE MÉME TYPE DE 5A, 125V.
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.
• Sn + Zn + Bi (tin + zinc + bismuth)
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.
■
TO SERVICE PERSONNEL
• Leakage current must not exceed 0.5mA.
• Be sure to test for leakage with the AC plug in both polarities.
