SAFE SERVICING PRACTICES - ALL APPLIANCES

To avoid personal injury and/or property damage, it is important that Safe

Servicing Practices be observed. The following are some limited examples of

safe practices:

1. DO NOT attempt a product repair if you have any doubts as to your ability to

complete it in a safe and satisfactory manner.

. Before servicing or moving an appliance:

 Remove the power cord from the electrical outlet, trip the circuit breaker to

the OFF position, or remove the fuse.

 Turn off the gas supply.

 Turn off the water supply.

3. Never interfere with the proper operation of any safety device.

4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE.

SU STITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETY

STANDARDS SET FOR HOME APPLIANCES.

5. GROUNDING: The standard color coding for safety ground wires is GREEN,

or GREEN with YELLOW STRIPES. Ground leads are not to be used as current

carrying conductors. It is EXTREMELY important that the service technician

reestablish all safety grounds prior to completion of service. Failure to do so

will create a hazard.

6. Prior to returning the product to service, ensure that:

 All electrical connections are correct and secure

 All electrical leads are properly dressed and secured away from sharp

edges, high-temperature components, and moving parts

 All non-insulated electrical terminals, connectors, heaters, etc. are

adequately spaced away from all metal parts and panels

 All safety grounds (both internal and external) are correctly and securely

connected

 All panels are properly and securely reassembled
