a.
Perform prestart procedures in paragraph 9-10.
b.
Make sure brine tank and holding tank are primed and holding tank is producing enough chlorine. If not, prime
tanks according to paragraph 9-13 and start generating and recirculating chlorine according to paragraph 9-14.
c.
Check sight on metering pump to ensure oil level is up to mark Add oil if necessary.
d.
Turn alarm ON/OFF switch on control cabinet (Figure 9-9) ON.
e.
Turn brine pump ON/OFF switch inside control cabinet (Figure 9-10) ON.
NOTE
There are two valves CU14 on Barge 1. Ensure that both are opened.

h.
Adjust chlorination unit cooling water flowmeter and pressure regulator (Figure 9-5) to 80 gph at 10 psi.
NOTE
A semiannual adjustment should be made using higher flow rate in summer and
lower flow rate in winter. Local climatic conditions should determine final flow
rate.
i.
Set chlorination unit makeup water flowmeter (Figure 9-5) to 36 gph.
