SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.)

5、 by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outl

6、et and turn the AC power switch on. Any current measured must not exceed 0.5 mA. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE Many electrical and mechani

7、cal parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safet
