C. A water separator is installed on the reservoir pressurization unit. The water separator is located upstream of the pressure reducing valve . The water separator makes sure that the air is clear of water. A reservoir presssurization ground connector is also installed on the unit. It makes it possible to pressurize the system from a ground service cart. A filter assembly is also installed on the unit.
D. An air pressure gage is installed in each system, adjacent to the related reservoir. Each reservoir has a pressure relief valve to prevent overpressurization of the reservoir.
E. Each reservoir has a reservoir depressurization valve to let the pressure out of the reservoir. The valve is installed in the related ground service panel.
