3.5 Fan Exhaust and Moisture Extraction Options
Start the extraction unit using the amber switch on the control panel; this is only functional when
the instrument switch is on.
The amount of air exhaust can be controlled by adjusting the slider under the exhaust box.
When the exhaust fan is turned on, there may be a drop in internal temperature before the oven
recovers to the setpoint value.
When working near to the maximum temperature, the airflow should be small to reduce the
amount of energy wasted in heating air.
3.6 Stoving and Curing Option
The oven is fitted with an explosion relief panel and a powered exhaust fan. The exhaust fan is
physically similar to that described above.
With this option the fan runs all the time that the oven is switched on.
A pressure switch detects that there is sufficient air flow through the chamber, and prevents the
oven from heating if the exhaust fan is not working correctly. If the pressure switch does not detect
sufficient air flow, a fault light comes on and the oven is prevented from heating up.
At least 200mm free space must be left at the back and sides of the oven to allow the explosion
relief panel to break out if there is a rapid build up of pressure inside the chamber.
