15.0 PREVENTATIVE MAINTENANCE & SERVICE
Warning!
Only qualified maintenance and electrical personnel should be allowed to perform any
maintenance or repair work.
Warning! Turn the main circuit breaker on the front of the oven to the OFF position and proceed
with your company’s Lock-Out / Tag-Out procedure before servicing or cleaning. This
should include turning off the main disconnect switch supplying oven power, or
disconnecting the oven power cord when applicable.
Frequency of preventative maintenance operations depends upon your particular process application and
frequency of use. Because of this, a hard and fast schedule of maintenance operations is difficult to present.
A set of guidelines suitable for an “average use” oven might not be sufficient for an oven with a high
frequency use. Therefore, the preventative maintenance measures given here are offered as a guide,
allowing you to arrange your own program.
A Preventative Maintenance Schedule / Log chart is provided at the end of this section. The suggested
inspection / service dates given are for average use.
