opening the fast-fill ball valve on the AMTA (fast-fill ball valve is
shown above). Charge the system to 13 psi/0.9 Bar minimum. Refer
to the “Air Supply Requirements” section.
10. Confirm that the system is charging by observing the system air
pressure gauge. If the gauge is not showing an increase in air
pressure, there is a leak or an opening in the line. Repair any leaks
or openings and restart the setup procedures.
11. Confirm that no water is being exhausted from the Auto Vent of
the Series 776 Low-Pressure Actuator. If water is being exhausted
from the Auto Vents, continue to run air through the system in
order to remove moisture from the upper chamber of the Series
776 Low-Pressure Actuator. If a Series 746-LPA Dry Accelerator is
installed, make sure the accelerator is not flooded.
