HTR-5890 2 HTR-5890 WALL OUTLETEQUIPMENT UNDER TESTAC LEAKAGE TESTER OR EQUIVALENT INSULATING TABLE WARNING: CHEMICAL CONTENT NOTICE! The 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 REA- SON 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. TO SERVICE PERSONNEL 1. Critical Components Information Components having special characteristics are marked s 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. CAUTION F1, F2: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A, 125V FUSE. CAUTION F1, F2: REPLACE WITH SAME TYPE 10A, 125V FUSE. ATTENTION F1, F2: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 10A, 125V. Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities. About Lead Free Solder The P.C.B.s installed in this unit are soldered using the following 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 + Ag + Cu (tin + silver + copper) - Sn + Cu (tin + copper) - Sn + Zn + Bi (tin + zinc + bismuth) Side A Side BSMT REFLOW Process MI FLOW Process Solder Dip $ B V U J P O 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.
