Sterilization
Introduction:
Steam Sterilization should be performed on the water distiller boiler and the
optional storage tank before the water distiller is used for the first time or after a
period of storage or non-use. After initial sterilization, the boiler should be steam
sterilized after any maintenance is performed and/or cleaning including the
descaling process. The optional storage tank requires cleaning and steam
sterilization after any maintenance, or if there are any problems with the quality of
the distilled water.
If there is a water quality concern and the system may be contaminated, it is
important to first remove the source of contamination and remove all
contaminated debris and then complete a Liquid Sterilization before a Steam
Sterilization.
Liquid Sterilization of Optional Storage tank
NOTE: This is performed whenever it is suspected that the water distiller
head or optional storage tank are contaminated.
1. It important to first remove the source of contamination and remove all
contaminated debris before liquid sterilization.
2. Drain the water distiller.
3. Add 1/2 gallon of Liquid Sterilizing solution to the water distiller optional
storage tank. If desired, spray some of the solution throughout the inside
of the optional storage tank. Drain a small amount of the sterilizing
solution out of the drain faucet to sterilize the faucet.
NOTE: Liquid Sterilization Solutions can be made from Household bleach.
The bleach should be diluted to 100-200 PPM. Products such as Javex,
have 6% Sodium Hypochlorite and should be diluted by placing 3
teaspoons per gallon of water. Always use Chlorine bleach that does not
contain any other ingredients. Alternatively, Hydrogen Peroxide solutions
may be used by placing 3 teaspoons per gallon of water.
4. Wait 20 minutes and drain the sterilizing solution.
5. Rinse the entire inside of the optional storage tank with at least 2 gallons
of distilled water.
6. Repeat the flushing of the optional storage tank with distilled water 2-3
times; continue until no chlorine smell is coming from the faucet.
7. Complete a Steam Sterilization of the boiling and optional storage tanks.
