This work package provides instructions for replacing the fuel and water drain valves. The procedure is the same for all
three models of the filter separator.
In normal operation, the filter/separator is filled with diesel/jet fuel. Diesel/jet fuel may explode if
subjected to high temperatures, sources of ignition or high pressure, resulting in bodily injury or death
to personnel. Keep all open flames, cigarettes, and any other sources of fire/flame or ignition a
minimum of 50 yards from any fuel servicing operations.
Diesel/jet fuel is toxic to skin, eyes and respiratory tract. Personnel must wear appropriate hand and
eye protection (nitrile gloves and goggles). Wash skin thoroughly with soap and water if exposed.
Flush eyes with clear water for at lest 15 minutes in case of contact with diesel/jet fuel.
Diesel/jet fuel fumes are toxic in high concentrations. Avoid prolonged breathing of vapors. Operation
and maintenance of the filter/separator should be performed only in a well-ventilated environment.
Failure to follow this warning may result in injury or death to personnel.
