8. If the valve is operating properly, set the motorized valve
operation back to automatic by setting the ‘Valve C/-/O 123’ to 2
then press enter and continue with system startup. If the valve is not
operating properly, check all system wiring and verify any settings
located on the valve are properly configured.
5.1.6 Pressure Test the System and Plumbing
This section only pertains If isolation valves are used, otherwise proceed to the
following section.
1. Ensure the downstream isolation valve is in the closed position
2. Slowly open the upstream isolation valve, pressurizing the system
3. Check all plumbing for leaks and address as needed
5.1.7 Verify System Pressure Differential
Verify that the pressure differential across the system is within the expected
range. This is the differential from before the motorized valve to after the turbine
discharge. Do NOT exceed the following limitations for pressure differential.
Turbine-Generator Model
Maximum Pressure Differential
M300-30
32 PSI MAX
M300-60
73 PSI MAX
CAUTION: If excessive pressure differential is present in the system a
small pressure reducing valve must be installed to reduce differential
to acceptable levels. Exceeding the rated levels can result in over-
generation and DAMAGE the equipment. See the appendix for adding a
pressure reduction valve.
5.1.8 Flow Water Through the System
Once proper wiring is verified, the control panel is energized, motorized valve
operation is verified and system pressure differential is verified proceed wth the
following:
1. Slowly open any valves downstream of the system.
