Section II. Prestart procedures
3-2 Prestart procedures
Before operating the chlorination system, be sure to check system for damage and perform before operation
preventive maintenance (paragraph 4-3).
Equipment Monitoring System (EMS) Indicates amount of chlorine in drinking water and
percentage of metering pump capacity being used.
Make sure EMS is operating. If not operating, start up according to instructions in TM 55-1930-20914&P-1.
Chlorination unit will operate unless void blower fan 8 is operating. Fan 8 circuit breaker 8P8
is on power panel 2 (amidships in ROWPU space starboard side).
Make sure that chlorine gas detector is operational. Detector is located in void 2 port, centerline bulkhead.
Alarm is located on ROWPU space bulkhead, forward.
Make sure switchboard circuit breakers P5 and P8 are closed to provide power to panels 1 and 2. Provide power
to chlorination unit control cabinet by closing power panel 1 circuit breaker 9P5. Provide power to metering
pump motor controller by closing power panel 1 circuit breaker 1 0P5. Provide power to vent fan 8 motor
controller by closing power panel 2 circuit breaker 8P8. Start vent fan 8 by pressing START button on motor
Seawater can be provided by seawater pumps or cooling water pump.
Make sure seawater system is ready for operation. If not operating, start by following procedures in TM 55-1930-
209-14 & P-2. Seawater, can be provided by either seawater pumps or cooling water pump.
Make sure seawater filter in line to chlorination system is clear and seawater pressure regulator is set to 10
pounds per square inch (psi).
When using drinking water, connect drinking water line to chlorination unit by connecting hose between valves
CU12 and CU12A. Make sure drinking water system holding tanks contain water and pressure set is ready for
operation. If not operating, start drinking water system by following procedures in TM 55-1930-209-14 & P-5.
Make sure ROWPU system is operational and can be started when chlorine solution is strong enough to provide
necessary chlorine to the product water. If not operational, follow maintenance procedures in TM 55-1930-209-
14 & P-3.
Check oil level on chlorination unit circulating pump (void port 2) to make sure oil is up to the mark. Add oil if
