Issue: There is water coming to the seal instead of steam.
Cause: Most likely the drain venturi nozzle has plugged up for some
reason. It is located in the flange of the drain.
Check if there is vapor and condensate coming out of the discharge nozzle of the optimizer.
- If nothing is coming out it means the venture nozzle is plugged. If it is working and discharging, we can leave it as is.
Do not over torque when closing – when no visible discharge is present no further torque is necessary.
- Open the emergency- and start blow-down valve to see if water comes out. If so, it means that the optimizer is flooded. Let it purge completely until steam comes out.
- Plan a scheduled 30 minutes to remove the counter flange and replace or pierce the venturi nozzle.
