Questions and answers

What speed should the WaFERS pump engine reach?

2. Adjust WaFERS pump engine speed to 1,200 RPM.

How should hydraulic pressure be adjusted during pump startup?

While watching the outlet pressure gauge, slowly turn the maximum pressure control knob clockwise to increase hydraulic pump speed. (paragraph 4)

How can the filter be identified as not full of fuel?

The filter is not full of fuel if air is escaping from the air vent located on recovery tank (T26). (paragraph 9)

What valves must be tested during initial startup?

During initial start-up, test the water slug-control pilot-valve(s) and flow control valve(s). (paragraph 9)

What is the role of the second filter in a duplex configuration?

When placed in this configuration, place either filter in service for continued fueling operation; the other filter is available for maintenance.
