When to Clean Your Separator

It is time to clean your Rockford Separator when you notice a gradual slow down of the unit draining. With normal use, you

should be able to establish a cleaning cycle. Whether once a week, or once a month. A thorough and regular cleaning each time

will assure maximum operating efciency, and will extend the life of your separator.

How to Clean Your Separator

1. Remove all grates to gain full access to the internal parts of the separator.

2. Remove all parts, and clean. Pump out the entire unit, removing all oily waste and sediment that will accumulate on the

bottom. DO NOT DISPOSE OF INTO THE SEWER.

3. Replace all parts. Call rockford if your separator parts are in need of replacement. All parts are usually in stock.

4. Run enough water to the separator, to restore the trap seal.
