isolated. Find and correct the cause before resetting the over-temperature controller
according to the instructions supplied.
DO NOT switch off if the temperature is above 100 °C - damage could be caused to the
fan and motor. Adjust the controller to allow the temperature to fall.
To turn the oven off, set the oven switch to it’s off position. If the oven is to be left off
unattended, isolate it from the electrical supply.
4.3 Over-Temperature Control (if fitted)
The over-temperature controller should typically be set at 15 °C above the main
controller. If an over-temperature condition occurs, check the main controller is
functioning correctly.
An over-temperature condition cuts off power to the heating elements. A light in the
over-temperature controller flashes. To reset this, refer to the over-temperature control
section of this manual.
4.4 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.
4.5 Exhaust Fan (if fitted)
To operate the exhaust fan use the fan switch on the control panel; this is
only functional when the instrument switch is on.
The level 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 product recovers to the setpoint value.
The airflow should be adjusted to the minimum required by the process to reduce the
amount of energy wasted in heating air.
4.6 Door Switch (if fitted)
If ordered, the door switch will isolate the heating elements and circulation fan. The
door switch is operated when the door is opened causing the heating elements and air
circulation fan to be switched off.
