Introduction:
Steam Sterilization should be performed on the water distiller boiler, filter
canister and 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 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 Storage Tank and Optional Pump Water
Line System
1.
It important to first remove the source of contamination and remove all
contaminated debris before liquid sterilization.
2. Drain the water distiller and water lines as much as possible.
3. Add 2 gallons of Liquid Sterilizing solution to the water distiller storage
tank. If desired, spray some of the solution throughout the inside of the
storage tank. You may need more sterilization solution if you are using
more that 25 feet of pump water line.
4. Run the pump by opening the faucet at the kitchen sink to put sterilizing
solution through all water lines and dispensers. All the lines will be full of
sterilization solution when you can smell the solution at the faucet. Wait
20 minutes.
5. Rinse the entire inside of the storage tank with at least 2 gallons of
distilled water. Run the pump to clear the lines of the sterilizing solution.
6. Repeat the flushing of the storage tank with distilled water 2-3 times,
rinsing the pump and all water lines at the same time. Continue until no
chlorine smell is coming from the faucet.
7. Complete a Steam Sterilization of the boiling and storage tanks.
NOTE: This is performed whenever it is suspected that the water distiller
head, storage tank or pump water line system are contaminated.
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 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
