NOTE
Refer to TM 5-6115-465-12 for operation of the generator set under unusual conditions.
Refer to TM 5-5430-227-12&P/TO 37A12-1-121 for operation of the collapsible water
tanks under unusual conditions.
2-18. FORDING
Avoid submerging the ROWPU during fording. Make sure canvas cover is down and securely fastened. Large volumes of
water entering the ROWPU skid may cause malfunctions in electrical devices, motors, and cabling. When fording models
WPES-20, H-9518-2, WPES-30, and H-9518-3, ensure skid is mounted high enough above stream (or water source) to
prevent flooding. After fording (Models WPES-10 and H-9518-1), wash the trailer with fresh water to remove mud and
other contaminants as soon as possible. Pay special attention to the electrical connections and brake hoses, the leaf springs,
and suspension assembly. Lubricate the entire vehicle in accordance with the instructions in the Lubricating Order, LO 10-
4610-241-12/TO 4OW4-13-51.
2-19. EMERGENCY PROCEDURES.
(Models WPES-10 and H-9518-1) If the air supply between the towing vehicle and the trailer air reservoir is interrupted, the
emergency spring brakes will lock. Notify unit maintenance to reset locked spring brake.
In the event of a fire, electrical short, or severe equipment malfunction during operation of the ROWPU, press the
EMERGENCY STOP button on the control panel.
2-20. WATER DEPTH/WAVE CONDITIONS.
When operating the ROWPU from a beach, special attention must be directed to sand conditions. Use care in placing the
suction hose strainer in the raw water source. Avoid turbulent water if possible. Waves stir up silt, sand, and debris which
can enter the raw water system. If waves of 2-4 feet at source water exist, or when water depth is too low to prevent sand or
debris from entering raw water suction hose strainer, it will be necessary to backwash the multimedia filter more often.
