How do I know when to change my vacuum pump oil?
One of the best ways of knowing when to change your vacuum pump oil is by
recognizing that batches of food that normally take 24 hours to complete, are taking
much longer (up to 48 hours to complete). When this occurs, it is time to change your
oil.
Another signal that your oil needs to be changed is by looking in the sight window. If the
oil looks milky, has visible particulates, or is amber in color, it is time to change the oil.
In most cases, your oil should be changed every 5-7 batches.
