Note
To prevent damage during transit the float may have been removed from the flowmeter on the front panel.
If so the following steps should be taken when installing the unit.
1. Remove the protective cover.
2. Remove the flow tube by first removing the plastic clip at the top of the flow tube, lift the flow tube
up and remove the bottom of the tube clear of the flowmeter assembly. Pull the tube downwards
from the top insert.
3. Fit the float with the pointed end down, into the tube.
4. Push the tube onto the top insert, line the tube up with the bottom insert, pull the flow tube and
the top insert down until the flow tube is fully engaged on the bottom insert, refit the plastic clip.
5. Refit the protective cover.
CONTROLS
The numbers refer to the item numbers on the diagrams
Mains on/off Switch (19)
Controls the mains input to the unit. This should be used in preference to the interlocks (see 'heater
indicator') when switching the unit off.
Mains Fuse (18)
Main fuse for the unit, rating 15A @ 240V AC.
Temperature Controller (16)
When the mains switch is set to the ON position the bath will fluidise and the temperature controller will
indicate the temperature of the fluidised bath in the upper display, while the lower display will always
indicate the set point temperature. The set temperature may be manually altered by depressing the
respective UP/DOWN key until the required value is indicated.
For further details of the Eurotherm 818P temperature controller see the attached manufacturers instruction
manuals.
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 uidising air pressure is above a preset value and the heaters are turned ON. When
the indicator is not illuminated the heaters are turned OFF.
