CHAPTER 2. OPERATING INSTRUCTIONS
SECTION I. DESCRIPTION AND USE OF OPERATOR'S CONTROLS AND INDICATORS.
General. The operator needs to know and understand the function of controls, indicator lights, and manually operated valves
used in operation and operator maintenance of the ROWPU. This section describes and shows all the operator controls. In addition to
controls, indicator lights, and manually operated valves, there are portable meters and gages used to measure water quality outside the
ISO container at the raw water intake and distribution points. During certain operational phases of the ROWPU hose hook-ups must be
Raw Water Pump Controls and Indicators (Refer to Table 2-1).
Electrical Switch Panels 1 and 2 (Refer to Table 2-2).
Main Control Panel Controls and Indicators (Refer to Table 2-3).
Controls. There are four selector switches, fourteen pushbuttons, and eight resets on the main control panel; the function
of each is described in Table 2-3.
Gages and Instruments. There are four pressure gages, three flowmeters, and two hourmeters on the panel.
Circuit Breakers. There is one MAIN circuit breaker which totally activates or shuts down the panel. This MAIN circuit
breaker is also a door interlock. The breaker is opened and all electrical power to the panel is interrupted when the door
is opened. There are eight overload circuit breakers on the panel.
Indicator Lights. Green lights indicate switch ON positions , blue lights indicate automatic valve positions. Yellow lights
indicate when operator action is required, red lights indicate conditions which will automatically shut the ROWPU down.
When yellow lights go on, a pulsed (WARNING) horn on switch panel 2 goes on, when red lights go on, a steady horn
sound (ALERT) goes on (this horn is also on switch panel 2).
Remote Meters and Gages. In-line meters and gages not associated with chemical and water status are described in Table
Manual Water Valves. The manual water flow control and drain valves with which the operator has interface are described in
Manual Chemical Controls (Refer to Table 2-6).
Air Supply Controls and Indicators (Refer to Table 2-7).
Oil Drain Plugs, Drain Valves and Oil Level Indicators (Refer to Table 2-8).
Diesel Heater Controls and Carbon Monoxide Monitor (Refer to Table 2-9).
Potable Water Distribution System Controls and Indicators (Refer to Table 2-10).
Portable Testing Meters and Gages (Refer to para. 2-5 thru 2-8).
