5. Disconnect wire leads from the transformer.

6. Remove two (2) screws holding the transformer to the

base cabinet.

Re-install

1. Rest the transformer on the base cabinet with its primary

terminals toward rear cabinet.

2. Insert the two edges of the transformer into two metal

tabs of the base cabinet.

3. Make sure the transformer is mounted correctly to the

corners underneath those tabs.

4. After re-installing the transformer, secure the transformer
