IMPORTANT SAFETY NOTE
The information provided herein is designed to assist qualified repair personnel only. Untrained persons
should not attempt to make repairs due to the possibility of electrical shock. Disconnect power cord
before servicing this appliance.
IMPORTANT
If any green grounding wires are removed during servicing, they must be returned to their original position
and properly secured.
CAUTION
All electrical parts and wiring must be shielded from torch flame. DO NOT allow torch to touch insulation;
it will char at 200°F and flash ignite (burn) at 500°F. Excessive heat will distort the plastic liner.
