When metering pump motor control MANUAL/OFF/AUTO witch Is In AUTO,
paddle flow switch In ROWPU product water line automatically starts and
stops metering pump. This action controls amount of chlorine the pump
Injects into the product water. When product water starts flowing, pump
starts and when product water stops flowing, metering pump stops.
Turn chlorine metering pump motor controller AUTO/OFF/MAN switch (Figure 3-2) to AUTO.
chlorination unit operates best when temperature of solution In holding
tank Is between 75 and 95 °F. Increasing cooling water flow decreases
temperature; decreasing flow increases temperature.
Turn metering pump control MANUAL/OFF/AUTO switch (Figure 3-3) to AUTO.
Chlorination system is now operating in conjunction with the seawater system, ROWPU system, and drinking
water system to provide correct amount of chlorine solution to ROWPU product water.
While chlorination system is operating, monitor the following for normal indications:
Chlorination unit panel (Figure 3-1)
Makeup water flowmeter - 36 gph
Cooling water flowmeter - 80 gph
Cooling water pressure gauge - 20-40 psi
Heat exchanger pressure gauge - 30-60 psi
When reading not normal, troubleshoot as necessary.

Chlorine status on LED display.
Chlorination unit control cabinet (Figure 3-5)
Ammeter - reading is between 950 to 1000 amperes (amps) (0.95-1.0 kilo amps)
Voltmeter - reading is between 6.0 to6.5 Vdc
Alarm - When alarm sounds, turn ON/OFF switch to OFF. Check if one of the following goes out
and troubleshoot as necessary:
Power supply failure light
Circulation (recirculation) pump failure light
Low salinity light
CHLORINE STATUS display page (Figure 3-8)
SYSTEM STATUS display page (Figure 3-9) - check the following:
CHLORINATOR OPERATING OFF is normal
CHLORINATOR PWR SUPPLY FAIL is normal
BRINE RCIR PMP OPERATING OFF is normal
