Section I. DESCRIPTION AND USE OF
OPERATOR'S CONTROLS AND INDICATORS
2-1. INTRODUCTION. The Forward Area Water Point Supply System (FAWPSS) is designed for operation in a wide
range of climatic conditions. Operators must be aware of any peculiarities or operational limitations for their specific
installation. Before setting up and operating this system, be sure that you have determined the type of terrain and
climate in which you will use the system and that you have assembled and serviced the system to match the existing
needs.
2-2. OPERATOR'S CONTROLS AND INDICATORS. This manual generally covers a FAWPSS less the pump and
engine assembly. For controls and indicators applicable to the pump and engine assembly, refer to the applicable
technical manual. The following items are the only remaining operator's controls for the FAWPSS.
a.
Ball Valve Assemblies. The two ball valve assemblies furnished with the FAWPSS are used to control the flow
of water between the two collapsible storage drums and the 125 pump and engine assembly. The ball valve is in the
open position when the handle on the valve is turned in the counter clockwise direction until the handle stop comes into
contact with the body of the valve. The ball valve is in the fully closed position when the handle is turned clockwise until
the handle stop again comes into contact with the body of the valve.
b. Nozzle Assemblies. The nozzle assemblies are used as the final dispensing component of the FAWPSS. After
positioning the nozzle over the container to be filled with potable water, the lever on the nozzle is depressed to allow
water to flow through the spout of the nozzle and into the container. When dispensing is complete, releasing the nozzle
will stop the flow of water from the nozzle.
c.
Collapsible Drum Assemblies. Each collapsible drum assembly is equipped with a coupler valve assembly to
control the flow of water from the drum.
Section II. OPERATOR PREVENTIVE MAINTENANCE
CHECKS AND SERVICES
2-3. GENERAL. Preventive Maintenance Checks and Services (PMCS) means systematic caring, inspecting, and
servicing of equipment to keep it in good condition and to prevent breakdowns. As the operator of the FAWPSS, your
mission is to:
a.
Be sure to perform your PMCS each time you operate your FAWPSS. Always do your PMCS in the same order,
so it gets to be a habit. Once you've had some practice, you'll quickly spot anything wrong.
