Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux

11、vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. I TO SERVICE PERSONNEL 1. Critical Components Information Components having special characteristics are marked s and must be replaced with parts having specific

12、ations 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.

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

15、 (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Side A Side B SMT REFLOW Process MI FLOW Process Solder Dip Caution: 1. As the melting point temperature of the lead free solder is about 30C to 40C (50F to 70F) higher than that of the lead solder, be sure to use a

16、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.
