SECTION IV. OPERATION UNDER UNUSUAL CONDITIONS
Refer to applicable manuals for operation of power generating equipment
during unusual conditions.
References to trailer are for Army Model 600-1 only.
FORDING. No special procedures are required before or during fording. After fording, wash the trailer
with fresh water to remove mud and other contaminants as soon as it is convenient to do so. Pay special attention
to the electrical connections and brake hoses, the springs, and the suspension assembly. Lubricate the entire
vehicle in accordance with the instructions in the Lubrication Order, LO 10-4610-239- 12/Ll 08580A-12.
EMERGENCY PROCEDURES. If the air supply from the towing vehicle and from the trailer air
reservoir should be interrupted, the emergency spring brakes will lock. Refer to fig. 2-82 as required to reset a
locked spring brake.
WATER DEPTH/WAVE CONDITIONS. When waves of 2-4 feet at water source exist, or when water
depth is too low to prevent sand or debris from entering strainer at water source, it will be
necessary to backwash
multimedia filter more often.
Generator set must not be operated in enclosed areas unless exhaust
discharge is properly vented to the outside. Death by suffocation due to carbon
monoxide is possible if this warning is not heeded.
COLD WEATHER. Locating, installing and operating the equipment at subfreezing temperatures
requires taking precautions. Adequate shelter and heating are required when operating in temperatures below
32° F (0°C). When locating the equipment take advantage of existing shelter and windbreaks. Erect tenting
shelters for protection. The filtered water storage tanks may be installed inside a tent or other shelter. Filtered
water may be recirculated with the distribution pump between the two filtered water storage tanks to prevent
freezing in the hose lines, tank outlets and pump. Fuel, coal or wood burning heaters or other heating devices may
be installed inside the erected tents to protect the equipment and prevent freezing of water. When the equipment
is to be shutdown, all hoses must be disconnected from pumps, and all pumps, hoses, pipes and tanks drained
quickly. All drain and vent valves must be opened and all equipment inspected to assure complete drainage.
During cold weather, keep in mind the following warnings, cautions and procedures:
Turn valves slowly during cold weather, because metal contracts and becomes
a. Inspect the ROWPU closely for split or frozen hoses, dogged strainer, etc.
To prevent hands from freezing to metal, wear rubber gloves when handling
and setting valves.
