3.5 The Oven Door and Chamber
It is recommended that the instrument switch is turned off if the oven door is to be opened when
the temperature is below 120°C. If the door is opened when on, and the set temperature is below
about 120°C, then the controller will attempt to compensate for the drop in temperature and the
actual temperature may exceed the set temperature when the door is closed again.
Also, remember that the fan is on when the instrument switch is on. Opening the door does not
switch off the fan.
The tip of the temperature sensor is visible on the right of the chamber, below the fan. It is not
electrically live, but it is delicate and should not be touched.
3.6 Loading and Unloading the Chamber
Where accurate temperature control of the load is important, use the central part of the chamber
and distribute the load to allow free air circulation. Do not place loads on the chamber floor: use
the bottom shelf.
Remember that the shelves and work pieces may be hot: use suitable gloves or other handling
equipment. Have a heat-resistant surface available on which to place hot materials.
There is no physical stop to prevent shelf removal: take care not to pull out a shelf accidentally.
Additional shelves may be obtained from Carbolite. The maximum load for each shelf is 10kg.
The maximum number of shelves and the maximum load for the oven depends on the model:

3.7 Vents
On the back of the unit are two vents, covered by a sliding baffle plate. The inlet vent is
permanently open, while the outlet may be opened or closed by means of the sliding plate.
The sliding plate gets hot. Do not touch it when the oven is hot. Make adjustments when the oven
is cold.
3.8 Explosive Vapours
These models are not suitable for drying or heat treatment applications where vapours are released
that are combustible or that can form explosive mixtures with air. Carbolite manufactures other
models suitable for these applications.
