temperature controller (16)
Units with Serial Number/9 onwards
When the mains switch (19) is set to the ON position the fluorescent indicator panel will display the measured
and set temperature in digital form. To alter the set point depress the respective UP/DOWN button and
after a delay of two seconds the set point will change in the required direction.
The control parameters have been factory pre-set if you need to know the latest values contact the Service
Department at Techne.
Fluidisation air Control (21)
The valve at the bottom of the flowmeter controls the amount of air for fluidising the bed, the amount
of flow being indicated by the float in the tube on a 2-25 scale.
extraction air switch (22)
Turns the dust extraction system on and off. Without dust extraction fine dust from the bath could escape
into the workroom atmosphere and although harmless, it has a nuisance value. The extraction system
should, therefore, be used whenever the bath is running.
Dust extraction Indicator (20)
Lights green when the dust extraction system is working.
heater indicator (20)
Lights orange when the heaters are on. Heaters are interlocked so that they will only turn on when fluidising
air is also on and exceeds a factory preset value.
