Maintenance
Do not attempt any service on this oven before opening the main power disconnect switch.
Danger!
Disconnect all power sources before making repairs. Contact
with energized electrical sources may result in serious injury or
death.
6.1. Checklist

Keep equipment clean. Gradual dirt accumulation retards airflow. A dirty oven can result in
unsatisfactory operation such as unbalanced temperature in the work chamber, reduced
heating capacity, reduced production, overheated components, and the like. Keep the walls,
floor and ceiling of the oven work chamber free of dirt and dust. Floating dust or accumulated
dirt may produce unsatisfactory work results. Keep all equipment accessible. Do not permit
other materials to be stored or piled against it.

Protect controls against excessive heat—particularly controls, motors or other equipment
containing electronic components. Temperatures greater than 50°C (122°F) should be
avoided.

Establish maintenance and checkup schedules. Do this promptly and follow the schedules
faithfully. Careful operation and maintenance will be more than paid for in continuous, safe
and economical operation.

Maintain equipment in good repair and make repairs immediately to avoid costly delays.

Practice safety. Make it a prime policy to know what you are doing before you do it. Make
caution, patience, and good judgment the safety watchwords for the operation of your oven.

Inspect oven seals if pressure readings decrease over time (Refer to Section 3.3.5 as well as
Table 6, Columns D and/or E)
Danger!
For LCC/LCD2-14A Class A ovens: Do not allow flammable
solvents, combustibles, or other organic material to accumulate
in Class A ovens, as this could lead to fire or explosion,
particularly if the maximum solvent rating of the oven is
exceeded.
