Automatic Damper
1.
Put the oven in operation (without a load in the chamber) and wait until the
temperature is stabilized.
2.
Set the controller to about 10
°
C lower.
3.
While looking at the damper control motor and linkage, when the setpoint is first
turned down, the dampers should move to the wide-open position.
4.
Then, as the chamber temperature drops, the dampers should start to close
when the difference between the chamber temperature and the setpoint is less
than 4
°
C.
5.
When the chamber temperature has dropped between 1
°
C and 2
°
C above the
setpoint, the damper should be fully closed.
6.
At lower chamber temperatures (compared to the setpoint), the damper remains
closed and the heater is turned on.
7.
Reset the temperature controller.
Controls and Indicators
Check all controls for proper operation. Switches should move easily, indicators should
light or give a correct signal, and controls should perform intended function.
Loose Screws, Bolts and Fasteners
Check tightness of all screws, bolts and fasteners. Notice whether the oven vibrates or
makes unusual noises while starting, running or stopping. Make sure switches and
control knobs and indicators are securely fastened.
Lubrication
Fan motor bearings are permanently lubricated. All door latches, hinges, door operating
mechanisms, bearing or wear surfaces should be lubricated to ensure easy operation.
