Filling the cooling system
The cooling system is self-priming; air in the system is removed automatically as
the cooling system operates. The coolant is a 1:10 solution of glycerol in water
(1 part glycerol plus 9 parts water).
Note: The cooling system contains 0.5 L glycerol when it leaves the factory.
(See 'Cooling system maintenance procedures' in the Graphite Furnace User's
Guide for the procedure to follow when you empty and refill the cooling system.
Do not use antifreeze.)
.
1. Remove the stopper from the top of the
cooling system – twist and pull.
2. Fill the system to the
sediment-free drinking water – about
4.5 L.
Do not use deionized water since this can
cause corrosion.
3. Replace the stopper securely.
