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.

. The symbols UL, EU, 55 and XX on the parts list
and the schematic diagram mean followings respectively.

UL ......... Manufactured for U.S.A. market.
(Underwriters Laboratories approved model.)
Manufactured for European market.

. Manufactured for Saudi Arabian market.
Standard Version.

NON MARK . . . Common Parts.

. Some printed circuit boards are not supplied assembled. To
separate these in this service manual, the part numbers are not
indicated for these boards. However, part numbers for individual
parts are indicated.
