the modules were tested for leaks and water-flow. Without this test no module will be sent out.
I dont understand why this is happend.
Shutter buckling problems will be happen when the water flow is off or less like the last time when
the new module was damage. In this case the flow meter was jumped and less water flow..
How many modules are damage?
Tell me the position where the damage it happened. Please check the water flow.
How many liters is the actual water flow. ( You can see it at the flow meter )
Where are the switch points of the flow meters. ( How many liters is the contact close point and how many liters is the contact open point)
Please sent me more Pictures and details.
