CAUTION

1. Parts identified by the A symbol on the schematic diagram and the parts list are critical for safety.
Use only replacement parts that have critical characteristics recommended by the manufacturer.

2. Make leakage-current or resistance measurements to determine that exposed parts are acceptably
insulated from the supply circuit before returning the appliance to the customer.

1. The symbols UL, SS and XX on the pans list and
the schematic diagram mean followings respectively.

UL ......... Manufactured for U.$.A. market.
