If overheating occurs in extreme conditions, shut down engine immediately. Be sure unit is operated in a
well ventilated area capable of allowing exhaust air to dissipate and to allow cool fresh air to enter engine intake If
possible protect pump assembly from direct heat or the sun
c. Operation in Sandy or Dusty Areas. Dusty and sandy conditions can seriously affect the operation of the DED
pump assembly. When operating the DED pump assembly in these dusty and sandy conditions, perform the following
steps.
(1)
Accumulation of dust or sand in the filters of the diesel engine will cause the pump to overheat and
damage the equipment. Have engine air filter replaced by unit maintenance and clean all other areas of dust and sand
accumulation frequently. In extreme conditions, daily replacement of filter may be necessary.
(2)
Water which has been contaminated by dust and sand can severely affect the usability of the water being
pumped by the DED pump assembly Special care must be taken that the water being pumped does not have dust or
sand in it when using the DED pump assembly in dusty and sandy conditions. Be sure that all hose and piping
connections are tight. Be sure that the insides of all DED pump assembly components are clean before piping
connections are made during DED pump assembly set up and assembly.
