Oven Safety Reset- To protect the oven’s electrical components and for the
safety of the user, if the unit exceeds its maximum temperature, an internal safety
“snap disc” will cut power OFF to the unit until it is manually reset.
To Reset - unplug the oven, lay it on its back, and remove the bottom cover.
Locate the round safety “snap disc” and push on the button to reset.
Maintenance / Cleaning Procedures / Common Replacement Parts
The Lab Series Ovens are designed to be virtually maintenance free. But operational safety requires periodic cleaning
and chamber temperature accuracy verification (see Temperature offset/calibration on page 3 of this manual).
Cleaning Procedure - Periodically check the rear air intake vents for dirt or dust build-up. Keep the intake &
exit ports clear of obstruction and clean of dust and dirt. To reduce the risk of fire, it may be necessary to remove the
bottom plate cover to clean or vacuum any dirt and dust build-up. To clean the exterior and interior surfaces, use a
damp cloth or an all-purpose cleaner. Avoid commercially available oven cleaners.
