Supplemental Manual
For Generating Hypochlorous Acid (HOCl)
How to Generate HOCl
The purpose of this supplemental manual is to explain
how to generate higher concentrations of HOCl using
less salt and
to present several options for optimizing
the pH to between pH 5 and pH 7.
1.
Ad
d
1 Liter of
reverse osmosis water (RO water should have pH <6)
If RO water is unavailable, use purified water or tap water and
lower
the pH by choosing one of the following methods:
a)
Add 1
teaspoon of 5% distilled vinegar
- or -
b)
Add 1 drop of muriatic acid (32% HCl) *
2.
Add 1 gram of salt . May also use as little as 1/2 gram.**
3.
Place
on
lid and plug-in the power supply ***
4.
Run
S
etting 3 once (8 minutes) to generate ~100 ppm
Run
S
etting 3 twice (16 minutes) to generate ~200 ppm
Each additional run on setting 3 will increase the
concentration by
6
0-
8
0 ppm
for a maximum of 5 total runs.

Press to Power On
Press once for Setting 1
Press twice for Setting 2
Press three times for Setting 3
Setting 3 – System runs for 8 minutes
Setting 2 – System runs for 5 minutes
Setting 1 – System runs for 3 minutes

Personal protective gear is required when using muriatic acid. '
This is the same muriatic acid that is used to lower the pH of pools.
**
Salt must be food grade salt (NaCl) without iodine (ie. kosher salt). When using
less than 1 gram of salt, it may be required to run 1 extra cycle of 8 minutes.
***
Power supply must be dry
