When priming tanks with water from drinking water system pressure set:
Open drinking water system valve DW17 in void 3 port to allow drinking water to flow to hose bib in
void 2 port.
Attach hose to hose bib on drinking water to chlorination system line in void 2 port.
Proceed to step i to prime brine tank or to step j to prime holding tank.
Prime brine tank as follows:
Remove lid from brine tank and turn chlorination valve CU7 to position C (close) to isolate brine tank.
Using hose previously attached to bib, fill brine tank half full of water.
Add salt to brine tank and stir manually until no more salt will dissolve in water (about 500pounds).
Replace lid on brine tank.
Prime holding tank as follows:
Open cap on Y-connection on top of holding tank and using hose previously attached to bib, fill to low
level mark (90 gallons).
Use manual salinity tester (Total Dissolved Solids Tester) according to TM 5-6630215-12 to test
seawater salt concentration. If test indicates seawater is about a 4% brine solution (40 per 1000 ppm),
no additional salt is needed in the holding tank. However, if tests indicate additional salt is necessary,
refer to chart below for amount of salt to add to holding tank.
Salt concentration of
seawater per 1000 ppm:
Salt required in lb:
If necessary, add proper amount of salt to agree with salt concentration as determined by salinity
Then replace cap on connection of holding tank.
Generate and circulate chlorine according to paragraph 3-6.
3-6 Chlorine generation and recirculation
Make sure holding tank has beenprimed according to paragraph 3-5,
Position CU valves as indicated below.
Close chlorination unit makeup water and cooling water flowmeter valves (Figure 3-1). Make sure brine
pump switch inside control cabinet (Figure 3-) is OFF.
Turn alarm switch on control cabinet (Figure 3-5) to OFF.
Turn function switch on control cabinet (Figure 3-5) to AUTO.
Chlorination system now makes chlorine sol ution of a proper concentration
In approximately 4 hours. When DC ammeter (Figure 3-5) Is reading 950 to
1000 amps (0.95 to 1.0 kilo amps), holding tank solution Is at proper level of
concentration. Add salt or water to holding tank as necessary.
