WARNING
See each chemical Material Data Safety Sheet for information regarding the specific hazards
associated with each chemical. Injury to personnel could result.
CAUTION
To prevent serious damage to the Reverse Osmosis (RO) membrane elements, never allow
water that contains chlorine to be introduced to the RO element module. Damage to
membrane elements will result.
Only the chlorine injection is mandatory. The other chemicals are to be injected depending
on source water conditions.
Sodium metabisulfite Mixing Instruction
NOTE
The Sodium metabisulfite container includes a double-ended scoop: a Large (tablespoon) and a small
(teaspoon) scoop.
1. If the raw water contains chlorine, sodium metabisulfite (M323) injection is required to neutralize it.
2. Add 50 grams (or two large scoops) of sodium metabisulfite (M323) for each parts per million (ppm) of
chlorine in the source water to the coagulant/sodium metabisulfite chemical tank T6. Chemical is identified
with a green diamond.
WARNING
To avoid injury from contact with the cleaning chemicals, be sure to wear the personnel
protective equipment (goggles, gloves, and apron).
3. Fill the appropriate tank with potable product water half way.
4. Make sure all caps are closed and tight on the tank before shaking. Mix solution well by shaking the
chemical tank T6.
5. Finish filling the chemical tank T6 with product water.
6. Open vent cap on the chemical tank T6 to expose the vent hole.
