What Should I Do If the Oil in My Harvest Right Freeze Dryer’s Vacuum Pump Looks Cloudy?
Cloudy oil in your vacuum pump usually means there’s moisture or other contaminants in the oil. This can affect how well your pump works and how long it lasts. Here’s how to fix it:
Step-by-Step Instructions
- Turn Off and Unplug the Pump
- Make sure your vacuum pump is turned off and unplugged from the power source before starting.
- Drain the Old Oil
- Place a container under the oil drain plug to catch the used oil.
- Open the drain plug and let all the oil drain out completely.
- Dispose of the old oil according to your local regulations.
- Clean the Oil Reservoir (Optional)
- If you can safely reach inside, wipe the inside of the oil reservoir with a clean, lint-free cloth to remove any leftover residue.
- Refill with Fresh Oil
- Pour in fresh, Harvest Right-recommended vacuum pump oil.
- Fill until the oil reaches the middle of the sight glass (the clear window on the pump) or the level marked for your model. Don’t overfill.
- Monitor the New Oil
- After running your freeze dryer, check the oil’s clarity and level.
- If the oil turns cloudy again quickly, there may be a deeper issue with your pump or system.
