5. ItisrecommendedthatwhentheMiniSectionDryerisrstturnedon,once
it has reached the set temperature the instrument should be left for 20
minutes before use, to allow the dryer chamber to fully equilibrate to the set
temperature.
6. The lid of the Mini Section Dryer has to be closed in order for the heaters on
the section dryer to operate. If the door of the section dryer is open, power to
the heaters is dis-engaged.
7. As slide racks are placed or removed from the chamber, the door will be open
and consequently the heater dis-engage.This will result in the temperature of
the chamber dropping from the set value. Once the door is closed the heaters
will re-engage and the temperature of the chamber will quickly return to the set
temperature.
