CHEMICAL INJECTION CONTINUED
4. Finish filling the chemical tank T5 with product water.
5. Open vent cap on the chemical tank T5 to expose the vent hole.
6. Retrieve antiscalant chemical injection tubing from the COEI box.
7. Connect chemical injection tubing from the chemical module antiscalant outlet to the antiscalant injection
point on the high-pressure pump module. See Figure 5 and Figure 6.

Hypochlorite Mixing Instruction
Hypochlorite is injected as a residual disinfectant. The water coming out from the RO module is fit for
consumption but hypochlorite is needed to keep the organisms from contaminating the stored water.
1.
Add 18 grams (2 packets) (9 grams (1 packet) if operating in seawater at 75 gph) of calcium hypochlorite
(M229) into the pail from the BII box with a few cups of product water to dissolve. Package is identified with
a yellow triangle. This amount will achieve about 1 ppm of free chlorine.
2.
Fill the tank T 7 half way with product water half way.
3.
Stir the mixture in the pail thoroughly. All solids will not dissolve. Allow the solids to settle to the bottom of
the pail.
CAUTION
To prevent damage to the chemical injection pumps ensure that undissolved solids are not
added to the chemical tank T7.
4. Add the dissolved Hypochlorite to chemical tank T7. Do not add the undissolved solids into the tank.
5. Make sure all caps are closed and tight on the tank before shaking. Mix solution well by shaking the
chemical tank T7.
6. Finish filling the chemical tank T7 with product water. Use the 6-foot hose.
7. Open vent cap on the chemical tank T7 to expose the vent hole.
