To disinfect a component:
1.
Review the maintenance instructions for the component that will be cleaned and disinfected. Specific
considerations must be taken into account for some components.
2.
Ensure UV assembly is shut down before disinfection.
3.
Clean the component with hot water and soap, and rinse with water. Remove biofilms and any surface
impurities. Avoid using hard or metallic brushes (to avoid surface abrasions) to clean and disinfect.
4.
Descale components using citric acid* (pH 2), then rinse with water.
l
*Let the component soak for 20 minutes and avoid scrubbing. Do NOT agitate the piezoelectric
transducers because they are very fragile.
5.
Apply disinfecting agent (0.1% hydrogen peroxide) to the component and allow to air dry (this allows the
agent to penetrate and kill pathogens).
6.
Rinse thoroughly with
clean
water (RO or DI water) to remove residue.
To disinfect hoses:
1.
Clean and disinfect hose connections, as described above.
2.
Remove any residue or particles from the hoses.
3.
Flush the hoses with hot water.
4.
Flush the hoses with disinfecting liquid and allow to air dry.
5.
Rinse the hoses with
clean
water (RO or DI water) to remove residue from disinfectant.
8.2.1
Diluting your Disinfecting Solution (H
2
O
2
) to 0.1%
A 0.1% hydrogen peroxide solution is recommended to disinfect the unit. If a 0.1% solution is not readily
available, you may need to dilute your current solution.
General Formula
Before mixing your solutions, you should know the following:
l
The desired concentration of disinfectant (Hydrogen Peroxide) in the mixture (0.1%).
l
The current concentration of the disinfectant (Halomist is 5% Hydrogen Peroxide).
If the total volume of the required final mixture is known:
1. Calculate the required volume of concentrated disinfectant
Required Volume of
Concentrated Disinfectant
=
[Desired Volume of Mixture]
x
[Desired Concentration of Mixture]%
[Concentration of Disinfectant]%
2. Calculate the required volume of fresh water
Required Volume of
Fresh Water
=
[Desired Volume of Mixture]
–
[Required Volume of Concentrated Disinfectant]
It may be easier to submerge some components of the unit into the disinfecting solution, or the volume of the
diluted solution may not be known (i.e. fresh water has already been secured).
