9 Maintenance

The distiller PRO-NITRO «A» uses NaOH and concentrated acids for the analysis
process. These substances are very aggressive and will degrade
some parts of the unit.
To avoid derating and increase distiller's life a suitable cleaning routine should be
done.

9.1 Cleaning the unit:

9.1.1 Clean the distillation circuit:
After any analysis session, distillate for 5 minutes in order to remove any rest of
NaOH on the distillation glassware. See 6.2
9.1.2 Cleaning the chamber:
The chamber is protected with a chemical resistant coating. But it should be daily
cleaned to increase its life.
Use a well damp cloth to clean the chamber and its components to remove any
rests of NaOH.
Clean the tray with abundant water.
9.1.3 Cleaning the NaOH and Boric acid hose connection
Approximately every 3 months, clean the NaOH and the fixative solution from the
tank hose connection with a wet cloth.
9.1.4 Cleaning the steam generator (weekly)
Switch off the equipment. Open the «Steam generator drainage valve» and wait till
it will be completely empty. Close the valve and start the equipment.
See how the steam generator is filled in chapter 5 of this manual.

9.2 Hose inspection (monthly)

Visually check the hose condition and its connections to components.
To avoid premature derating of the unit due to liquid leakage, replace as soon as
possible any hose that has any leakage or damage.
9.2.1 Hose replacing:
Take these cautions to hose replacing:
• Unplug the unit from the electrical power supply.
• Check, as you can, (See 9.3) that the hose to remove is empty.
• Use only tubes material as indicated on 11.2.
