4.0 Operation
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 Gero. The maximum load for each
shelf is 10 kg.
The maximum number of shelves and the maximum load for the oven are listed below:

Vents
On the back of the product 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 product is hot. Make adjustments
when the product is cold.
4.5
Temperature Control
The temperature is controlled by an easy-to-operate digital unit. The oven temperature
range is from 40 °C to 250 °C, though the minimum temperature may be higher if the
ambient temperature is above 30 °C.
A matching digital timer is available to order, or may be retro-fitted. A second option is
an over-temperature control device. There is also the option of a locking handle.
Temperature accuracy is enhanced by the use of a Type K thermocouple as the
temperature control sensor. A simple air-flow adjustment may be made by movement
of a sliding vent control mounted at the back of the oven. Typical air-flow with the vent
open is 1850 litres/ hour at 100 °C, giving exchanges in chamber volumes per hour of
65 (AX 30), 28 (AX 60) or 14 (AX 120).

Explosive Vapours
Unless your product includes the stoving and curing option, this model is
not suitable for drying or heat treatment applications where vapours are
released that are combustible or which can form explosive mixtures with
air. Carbolite Gero manufactures other products suitable for these
applications.
