Shut down procedure
When analysis of all samples has been completed, it is necessary to aspirate deionised water for a period of not less than 10-15 minutes depending
on the concentration and type of samples under test. This will ensure the mixing chamber and nebuliser are clean and ready for future use.
Once the cleaning protocol has been completed, the flame should be extinguished.
From the Main menu press back/STOP and then the accept key to extinguish the flame.
The flame out LED should be illuminated and the instrument will return to the Welcome menu.
Turn off the gas supply.
Check the flame has extinguished via the Chimney Inspection Port.
Turn off the external air supply (if being used) ONLY when the flame is extinguished.
Do not turn off the power to the instrument until the fan on the rear of the chimney has stopped spinning. Serious heat damage to internal
components can occur if the instrument is turned off before a sufficient cool down has been permitted.
