SERVICING SAFEGAURDS:
To avoid personal injury and/or property damage, it is important that safe servicing practices be observed at all times. Examples of
safe service practices are listed below but are not limited to the following:
1) Never attempt a product repair if you have any doubts as to your ability to complete the repair in a safe and
satisfactory manner.
2) Before servicing or removing an appliance:
- Disconnect power to the appliance.
- Turn off the gas / LP supply.
- Turn off the water supply.
3) Never interfere with the proper operation of any safety device.
4) Use only genuine factory replacement parts as substitutions may interfere with compliances to home safety codes or standards.
5) It is extremely important that all safety ground connections be reestablished prior to the completion of the service call. Failure to
do so will result in a hazardous condition being created.
6) Prior to returning the appliance back into active service, ensure the following:
- All electrical connections are correct and secure.
- 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 metal parts or panels.
- All safety grounds (both internal and external) are correctly and securely connected.
- All access panels are properly and securely reassembled.
