The Bench Series Ovens are designed to be virtually maintenance free.
But operational safety requires periodic clean-
ing and chamber temperature accuracy verification.
CLEANING PROCEDURE
CONTROL CALIBRATION
Twice a year, check the actual oven chamber temperature against a known accurate temperature measurement
device. Maintain temperature accuracy to your models specified specifications. (see Control Calibration on page 4.)
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. This will keep the motor from overheating and reduce risk of fire. It may be necessary to remove
the rear electrical cover to clean or vacuum dirt and dust from in & around the motor. Unplug the oven before
removing the rear cover. To clean exterior and interior surfaces, use a damp cloth or an all-purpose cleaner. Avoid com-
mercially available oven cleaners.
