TM 10-4320-346-12&P Section IV. OPERATION UNDER UNUSUAL CONDITIONS 2-12. OPERATION UNDER UNUSUAL WEATHER. The FAWPSS is designed to operate normally within a wide range of climatic conditions. However, some extreme conditions require special operating and servicing procedures to prevent undue loading and excessive wear on the equipment. These unusual conditions and the special steps to be performed are listed in the following paragraphs. a. Operation In Extreme Cold. When operating the FAWPSS in temperatures down to -50°F (-45°C), extra care should be taken to minimize possible injury to personnel and damage to equipment. Special cold weather procedures must be followed for operation of the pump and engine assembly and collapsible water drums which are part of this FAWPSS. Refer to the applicable technical maintenance manual for the procedures to follow when operating these items in extremely cold temperatures. WARNING Water can freeze very quickly and can quickly lower the temperature of exposed skin until there is a great danger of frost bite. Prevent leakage of water onto bare skin of personnel. Remove any water from exposed skin as soon as possible. CAUTION Freezing water can badly damage the FAWPSS components. When FAWPSS operations are completed at temperatures below 32°F (0°C), disconnect each end of all hose assemblies to prevent freezing water from damaging equipment. b. Operation In Sandy or Dusty Conditions. Dusty and sandy conditions can seriously affect the operation of the FAWPSS. When operating the FAWPSS in these dusty and sandy conditions, perform the following steps. (1) Accumulation of dust or sand in the filters of the pump and engine assembly will cause the pump to overheat and damage the equipment. Frequently clean filters and all other areas of dust and sand accumulation. In extreme conditions, daily cleaning of filters may be necessary. Refer to the technical maintenance manual for the pump and engine assembly for detailed procedures which must be performed when the pump is used in dusty and sandy conditions. (2) Water which has been contaminated by dust and sand can severely affect the usability of the water. Special care must be taken that the water being pumped does not have dust or sand in it when using the FAWPSS in dusty and sandy conditions. Be sure that all hose and piping connections are tight. Be sure that the insides of all FAWPSS components are clean before piping connections are made during FAWPSS set up and assembly. 2-12
