B-90 Operation Manual, Version B
5.10 Final installation check
This check has to be carried out after every installation and prior to the first spray drying process. All
connected supply media (e.g. mains voltage and gas pressure) must match the technical data of the
installed system or system set-up.
• Inspect all glass components for damage.
• Check the gas tubing connections and gas supply for leakages and good condition.
• Check that the complete set-up is sealed tightly and in sequence.
• Switch off the Nano Spray Dryer B-90. Check the high voltage cable of the electrical particle
collector for proper seating.
• Check all other electrical connections for proper connection, such as optional or external compo-
nents, for example: temperature sensors, heater, peristaltic pump cabling. The number of sensors
to be checked depends on the actual configuration.
NOTE
At 100 liter/minute gas flow, the internal pressure reading should be in the range of 30 to 60 mbar for
a well sealed system in ‘open loop’.
5.11 Electrical connections
After the installation procedure and the final check has been completed successfully, the power plug
of the Nano Spray Dryer B-90 and optional instruments must be connected to the mains for the spray
drying process.
Notice
Risk of instrument damage by wrong mains supply.
• External mains supply must meet the voltage given on the type plate
• Check for sufficient grounding
The used mains circuit has to:
• provide the voltage that is given on the type plate of the instrument.
• be able to handle the load of the connected instruments.
• be equipped with adequat fusage and electrical safety measures, in particular proper earthing.
See also technical data of all components regarding the different minimum system requirements!
NOTE
Additional electrical safety measures such as residual current brakers may be necessary to meet
local laws and regulations! External connections and extension lines must be provided with an
earthed conductor lead (3-pole couplings, cord or plug equipment). All used power cords shall be
equipped with molded plugs only to avoid risks due to unobservant defective wiring.
