If you are experiencing smoke or vapor coming from the lid of your pump, it could indicate a problem with the demister. We recommend starting by cleaning the demister. You can follow the instructions in this video: How to Remove and Clean the Demister.

After cleaning the demister, if the issue persists, it may be necessary to replace the demister. You can contact Harvest Right support to order the replacement parts.

Additionally, excessive smoke or vapor could also be caused by other factors such as skipping stages of the batch, a vacuum pump that is not working adequately, or a door gasket or drain valve that has an air leak. To troubleshoot these issues, you can refer to this video: High Pressure Checks.
