Safety, Care and Handling ............................................................................................................1-9
1-13. PRINCIPLES OF OPERATION.
a. General. The 20K and 50K collapsible water tanks described in this manual are functional components of a
water distribution system. Any number of water tanks may be connected to the system, depending on operational
requirements.
b. Filling. Potable water to fill the water tank is supplied by a water distribution system. The system water pumps
draw water from the source (tanker truck, pipeline, or purification equipment) and pump it into the water tank through the
filler assembly. Control of water flow between the supply pumps and the water tank is accomplished by opening or
closing gate valves within the system supply circuit. As the water tank fills, the tank will enlarge. When the tank is full,
or no more water is needed, supply circuit gate valves are then closed. Excessive pressures caused by overfilling the
tank are relieved by the vent fitting assembly. The vent unseats when internal water pressure exceeds 0.10 psi (0.00680
Atmospheres). The 4-inch gate valve supplied with the tank may be installed on the filler elbow to control water tank fill
rate.
c. Discharge. When needed, water is drawn from the tank by system suction pumps, and distributed through a
network of valves and hoses to the field installed facilities. As water is drawn from the tank, tank will flatten. Water flow
between the system discharge pumps and the water tank is controlled by system gate valves. The 4-inch gate valve
supplied with the tank may be installed on the discharge elbow to control water tank discharge rate. When the tank is
empty, or no more water is needed, the down stream system discharge gate valves are then closed. Venting of the tank
during discharge is not required.
d. Draining. A hand operated valve connected to the tank drain fitting controls water flow from the tank. This valve
allows a restricted flow of water from the tank for sampling or complete drainage. When preparing the tank for
movement, the system suction pumps will draw most of the water from the tank. To ensure complete drainage, the hand
valve is opened.
1-14. SAFETY, CARE, AND HANDLING.
Observe all Warnings, Cautions and Notes in this manual. This equipment can be dangerous or may be damaged if
these instructions are not followed.

a. This section provides a general explanation of all maintenance and repair functions authorized at various
maintenance categories.
b. The Maintenance Allocation Chart (MAC) in section II designates overall authority and responsibility for the
performance of maintenance functions on the identified end item or component. The application of the maintenance
functions to the end item or component will be consistent with the capacities and capabilities of the designated
maintenance categories.
c. Section III lists the tools and test equipment (both special tools and common tool sets) required for each
maintenance function as referenced from section II.
d. Section IV contains supplemental instructions and explanatory notes for a particular maintenance function.
B-2. MAINTENANCE FUNCTIONS.
Maintenance functions will be limited to and are defined as follows:
a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical
characteristics with established standards through examination (i.e., by sight, sound, or feel).
b. Test. To verify serviceability by measuring the mechanical or electrical characteristics of an item and comparing
those characteristics with prescribed standards.
c. Service. Operations required periodically to keep an item in proper operating condition, i.e., to clean (includes
decontamination, when required), to preserve, to paint, or to replenish fuel, lubricants, chemical fluids, or gases.
d. Adjust. To maintain or regulate, within prescribed limits, by bringing into proper or exact position, or by setting
the operating characteristics to specified parameters.
e. Aline. To adjust specified variable elements of an item to bring about optimum or desired performance.
f. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or test, measuring,
and diagnostic equipment used in precision measurement. Consists of comparisons of two instruments, one of which is a
certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being
compared.

B-2. MAINTENANCE FUNCTIONS (Cont).
g. Remove/Install. To remove and install the same item when required to perform service or other maintenance
functions. Install may be the act of emplacing, seating, or fixing into position a spare, repair part, or module (component
or assembly) in a manner to allow the proper functioning of an equipment or system.
h. Replace. To remove an unserviceable item and install a serviceable counterpart in its place.
Replace is authorized by the MAC and is shown as the 3rd position code of the SMR code.
i. Repair. The application of maintenance services or other maintenance actions to restore serviceability to an
item by correcting specific damage, fault, malfunction, or failure in a part, subassembly, module (component or
assembly), end item, or system.
j. Overhaul.
That maintenance effort (service/action) prescribed to restore an item to a completely
serviceable/operational condition as required by maintenance standards in appropriate technical publications (i.e.,
DMWR). Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not normally
return an item to like new condition.
k. Rebuild. Consists of those services/actions necessary for the restoration of unserviceable equipment to a likenew condition in accordance with original manufacturing standards. Rebuild is the highest degree of material
maintenance applied to Army equipment. The rebuild operation includes the act of returning to zero those age
measurements (hours/miles, etc.) considered in classifying Army equipment and components.
B-3. EXPLANATION OF COLUMNS IN THE MAC, SECTION II
a. Column 1 Group Number. Column I lists functional group code numbers, the purpose of which is to
identify maintenance significant components, assemblies, subassemblies, and modules with the next higher assembly.
b. Column 2 Component/Assembly.
Column 2 contains the names of components, assemblies,
subassemblies, and modules for which maintenance is authorized.
c. Column 3 Maintenance Function. Column 3 lists the functions to be performed on the item listed in
Column 2. (For detailed explanation of these functions, see paragraph 1-2.)
d. Column 4 Maintenance Category. Column 4 specifies, by the listing of a work time figure in the
appropriate subcolumn(s), the category of maintenance authorized to perform the function listed in Column 3. This figure
represents the active time required to perform that maintenance function at the indicated category of maintenance. If the
number or complexity of the tasks within the listed maintenance function varies at different maintenance categories,
appropriate work time figures will be shown for each category. The work time figure represents the average time
required to restore an item (assembly, subassembly, component, module, end item, or system) to a serviceable condition
under typical field operating conditions.
This time includes preparation time (including any necessary
disassembly/assembly time), troubleshooting/fault location time, and quality assurance/quality control time in addition to

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
