7 MAINTENANCE
7.1 DISTILLATION CHAMBER
After each distillation the distillation chamber must be washed with water to prevent contamination of the
successive sample.
Periodically clean the distillation chamber introducing approximately 500 ml of distilled or demineralised
water and approximately 20 ml of sodium chloride NaCl 1% solution. Start the distillation.
To remove deposits or incrustations that the samples can have left on the electrodes and/or on the glass
can be done in the two following ways:
Pour into the distillation chamber a dilute solution of HCl 0,1N. Await some hour and eventually
use a tube-brush to clean the chamber.
or
Introduce into the distillation chamber the solution B, supplied with the instrument, in sufficient
quantity to cover the incrustations. Also in this case to await some hour and use eventually a
tube-brush.
In any case rinse always accurately the distillation chamber before reuse the instrument.
WARNING! Don’t press the START button when into the distillation chamber there is a cleaning
solution. For more safety remove the power socket from the main.
7.2 ELECTRODES
The electrodes will gradually diminish in size and will have to be replaced at some stage. It is difficult to
predict the frequency of replacement because it will depend on total usage and type of sample (approx.
2000 tests).
For the replacement call the SAT (Service) of GIBERTINI - Phone (+39) 023541434 or your
supplier.
7.3 RECTIFICATION COLUMN
During the normal use of the SUPER DEE SV, the column does not require a particular cleaning. But, if
the column is contaminated by acid residuals, it is necessary to clean in this way:
fill the distillation chamber with about 500 ml of distilled water and 20 m of sodium chloride NaCl
1 % solution. Start distillation.
It is not necessary to collect the distillate. Stop the distillation holding pressed toward the balance for
some second
7.4 EMPTYING FUNCTION
Switch off the DISTILLATOR with the ON/OFF SWITCH.
Switch on pressing simultaneously the
B
key on the keyboard.
The display shows the message “ Take off water tube Wait for tank drain”
Empty the cooling coil using the shower.
Wait for the complete emptying of the distilled water tank by means of the steam pump (the water
finishes to go out by the nozzle and the pump becomes very noisy). Switch off the instrument.
Incline the instrument backwards to help the exit of water.
