grounding of the generator and ROWPU will prevent injury to your operating crew. Verify placement of a fire extinguisher
within 25 feet of the generator and ensure that there are no open flames within 50 feet.
Supervising Connection of Waste Outlet and Sump Drain Hoses. Ensure that personnel remove caps from the ends of the
waste hose section or waste will back up into the ROWPU. Ensure that the waste outlet adapter is connected to the waste-out
connection. Use enough waste hose sections to reach the water. Place the open end back in the water at least 50 feet from the
intake strainer (downstream in a river). Remind personnel to connect the sump drain hose to the drain-out connection; also,
see that they place the discharge ends downstream and away from work areas. Remind them that by correctly placing these
connections, the waste materials will be discharged safely.
Monitoring the Setup of the Water Distribution System. Ensure that personnel remove the protective caps from the hoses
only when they are ready to make a connection. Remind them that premature removal will allow dirt and sand to get into the
hoses. Ensure personnel also inspect hose gaskets before making connections and remind them to replace any damaged
gaskets. In setting up for a narrow river with deep water, you should ensure the intake strainer is placed in the center of the
river.
Supervising Initial Adjustments. Before starting operations, you need to see that personnel properly check, adjust, and test
the equipment to ensure that once the ROWPU starts up it will run at 20-hour intervals, shutting down for 4-hour maintenance
service periods only (see Part E - Preventive Maintenance). Among the items for personnel to check or test are:
Check hose couplings.
Check electrical cable connectors.
Check ground rod.
Check ground cables.
Check portable turbidity meter.
Test watercolor with Color Test Kit.
Check TDS meter
Check system mode switch.
Check generator.
Check system reset.
Check main circuit breaker.
Check air system.
Check lights.
Check manual valves.
Check vent, drain, and sample valves.
Check main control panel.
Check utility air hose.
Check emergency stop button.
Check cartridge filters.
PART D - OPERATIONS REQUIREMENT
Monitoring 3,000-GPH ROWPU Operation. The 3,000-GPH ROWPU requires little monitoring. Instead, you need to
ensure that personnel watch for warning lights, listen for the alarm horn, and perform
