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, and the like. Keep the walls, floor and ceiling of the
oven work chamber free of dirt, dust, smoke, solvent vapors, or other contaminations.

Keep all equipment accessible. Allow space for good circulation. Do not permit other
materials to be stored or piled against it.

Do not place load too close to the supply duct. The supply air temperature is somewhat higher
than average work space temperature and may overheat or otherwise damage product.

Do not put product on the floor or in isolated corners where air movement and temperature
are not likely to be at average conditions.

Do not mix thick heavy parts with light parts. The heavy parts require longer to heat and
should be treated separately.

Check safety controls. This should be done daily and never less than once a week. Establish
maintenance and checkup schedules. Maintain equipment in good repair and adjustment at all
times. Make repairs immediately to avoid costly delays.
